Table of Contents

4.1 Quick Installation Guide
4.2 Differences Between Binary And Source Distributions
4.3 Obtaining Connector/Python
4.4 Installing Connector/Python from a Binary Distribution
4.4.1 Installing Connector/Python with pip
4.4.2 Installing by RPMs
4.5 Installing Connector/Python from a Source Distribution
4.6 Verifying Your Connector/Python Installation

+ Connector/Python runs on any platform where Python is installed. Make sure + Python is installed on your platform: +

  • + Python comes preinstalled on most Unix and Unix-like systems, + such as Linux, macOS, and FreeBSD. If your system does not have + Python preinstalled for some reasons, use its software + management system to install it. +

  • + For Microsoft Windows, a Python installer is available at the + Python + Download website or via the Microsoft Store. +

+ Also make sure Python in your system path. +

+ Connector/Python includes the classic and X DevAPI APIs, which are + installed separately. Each can be installed by a binary or source + distribution. +

+ Binaries of Connector/Python are distributed in the + RPM + and the + wheel + package formats. The source code, on the other hand, is distributed + as a compressed archive of source files, from which a wheel package + can be built. +

4.1 Quick Installation Guide

+ The recommended way to install Connector/Python is by + pip and wheel + packages. If your system does not have pip, you + can install it with your system's software manager, or with a + standalone + pip installer. +

Note

+ You are strongly recommended to use the latest version of + pip to install Connector/Python. Upgrade your + pip version if needed. +

+ Install the Connector/Python interfaces for the classic MySQL + protocol and the X Protocol, respectively, with the following + commands. + 

# classic API
+$ pip install mysql-connector-python
+
+# X DevAPI
+$ pip install mysqlx-connector-python
+

+ Refer to the + installation + tutorial for alternate means to install X DevAPI. +

4.2 Differences Between Binary And Source Distributions

+ Installing from a + wheel + (bdist package) is the recommended, except for + Enterprise Linux systems, on which the RPM-based installation + method may be preferred. +

+ Wheels can be directly and easily installed without an extra build + step. However, a wheel package is often specific to a particular + platform and Python version, so there may be cases in which + pip cannot find a suitable wheel package based + on your platform or your Python version. When that happens, you + can get the + source + distribution (sdist) and produce a + wheel package from it for installing Connector/Python. +

Note

+ Creating a wheel package from an sdist may + fail for some older Python version, as the Connector/Python + source code is only compatible with a specific subset of Python + versions. +

+ In summary, the recommendation is to use a + bdist unless pip cannot find + a suitable wheel package for your setup, or if you need to custom + build a wheel package for some special reasons. +

4.3 Obtaining Connector/Python

Using pip is the preferred method to obtain, - install, and upgrade Connector/Python. Alternatively, see the + install, and upgrade Connector/Python. For alternatives, see the Connector/Python download site.

Note

The mysql-connector-python package installs - an interface to the commonly used classic MySQL protocol. - Alternatively, an X DevAPI interface is available as its own - mysqlx-connector-python package. Prior to - Connector/Python 8.3.0, mysql-connector-python installed - interfaces to both the X and classic protocols. + an interface to the classic MySQL protocol. The X DevAPI is + available by its own mysqlx-connector-python + package. Prior to Connector/Python 8.3.0, + mysql-connector-python installed interfaces + to both the X and classic protocols.

- Debian, Solaris, and most RPM (except Enterprise Linux) packages - are not available from dev.mysql.com. Instead, using - pip to manage Connector/Python is recommended. Packages - for those platforms were available before Connector/Python 9.0.0. -

4.2 Installing Connector/Python from a Binary Distribution

Installing Connector/Python with pip

- Use pip to install and upgrade Connector/Python: - 

# Installation
+      Most Linux installation packages (except RPMs for Enterprise
+      Linux) are no longer available from Oracle since Connector/Python
+      9.0.0. Using pip to manage Connector/Python on
+      those Linux distributions is recommended.
+

4.4 Installing Connector/Python from a Binary Distribution

4.4.1 Installing Connector/Python with pip
4.4.2 Installing by RPMs

+ Connector/Python includes the classic and X DevAPI connector APIs, + which are installed separately. Each can be installed by a binary + distribution. +

+ Binaries are distributed in the + RPM + and the + wheel + package formats. +

4.4.1 Installing Connector/Python with pip

+ Installation via pip is supported on Windows, + macOS, and Linux platforms. +

Note

+ For macOS platforms, DMG installer packages were available for + Connector/Python 8.0 and earlier. +

+ Use pip to install and upgrade Connector/Python: + 

# Installation
 $> pip install mysql-connector-python
 
 # Upgrade
 $> pip install mysql-connector-python --upgrade
 
-# Optional, installs the X DevAPI interface
+# Optionally, install X DevAPI 
 $> pip install mysqlx-connector-python
-

Installing Connector/Python on Microsoft Windows

- Use pip; installing Python on Windows also makes pip available - from the command line (cmd.exe). -

Installing Connector/Python on macOS

- Use pip; installing Python on macOS also makes pip available. -

Note

- DMG installer packages were available before Connector/Python 8.1.0. -

Installing Connector/Python on Linux Using the MySQL Yum Repository

- EL-based platforms can optionally use RPMs instead of pip, either - by using the - Connector/Python RPM - downloads or by using the MySQL Yum repository (see - Installing Additional MySQL Products and Components with Yum and - Adding the MySQL Yum Repository). -

RPM Prerequisites

  • - A python3-protobuf RPM package is not - available for Python 3.8 on these platforms, so the dependency - is not part of the RPM specification; instead it must be - manually installed with the likes of pip install - protobuf. This is required as of v8.0.29. -

  • - The mysql-community-client-plugins package - is required to use modern authentication methods, such as - caching_sha2_password, which is the default - authentication method as of MySQL 8.0. - 

$> sudo yum install mysql-community-client-plugins
-

- Then install Connector/Python as follows: - 

$> sudo yum install mysql-connector-python
-

Installing Connector/Python on Linux Using an RPM Package

- Connector/Python Linux RPM packages (.rpm files) are - available from the Connector/Python download site (see - Section 4.1, “Obtaining Connector/Python”). -

- To install a Connector/Python RPM package (denoted here as - PACKAGE.rpm), use - this command: - 

$> rpm -i PACKAGE.rpm
-

Prerequisites

  • - A python3-protobuf RPM package is not - available for Python 3.8 on these platforms, so the dependency - is not part of the RPM specification; instead it must be - manually installed with the likes of pip install - protobuf. This is required as of v8.0.29. -

  • - The mysql-community-client-plugins package - is required to use newer authentication methods, such as - caching_sha2_password, which is the default - authentication method as of MySQL 8.0. -

- RPM provides a feature to verify the integrity and authenticity of - packages before installing them. To learn more, see - Verifying Package Integrity Using MD5 Checksums or GnuPG. -

4.3 Installing Connector/Python from a Source Distribution

- Connector/Python source distributions are platform independent and can be - used on any platform. Source distributions are packaged in two - formats: + +# Upgrade X DevAPI +$> pip install mysqlx-connector-python --upgrade + +

+ In case the wheel package you want to install is found in your + local file system (for example, you produced a wheel package + from a source distribution or downloaded it from somewhere), you + can install it as follows: + 

# Installation
+$ pip install /path/to/wheel/<wheel package name>.whl
+

Installation of Optional Features

+ Installation from wheels allow you to install optional + dependencies to enable certain features with Connector/Python. + For example: + 

# 3rd party packages to enable the telemetry functionality are installed
+$ pip install mysql-connector-python[telemetry]
+

+ Similarly, for X DevAPI: + 

# 3rd party packages to enable the compression functionality are installed
+$ pip install mysqlx-connector-python[compression]
+

+ These installation options are shortcuts to install all the + dependencies needed by some particular features (they are only + for your convenience, and you can always install the required + dependencies for a feature by yourself): +

  • + For the classic protocol: +

    • + dns-srv +

    • + gssapi +

    • + fido2 +

    • + telemetry +

  • + For X Protocol: +

    • + dns-srv +

    • + compression +

+ You can specify a multiple of these options in your installation + command, for example: + +

$ pip install mysql-connector-python[telemetry,dns-srv,...]

+ + Or, if are installing a wheel package from your local file + system: + +

$ pip install /path/to/wheel/<wheel package name>.whl[telemetry,dns-srv,...]

+

4.4.2 Installing by RPMs

4.4.2.1 Using the MySQL Yum Repository
4.4.2.2 Using an RPM Package

+ Installation by RPMs is only supported on RedHat Enterprise + Linux and Oracle Linux, and is performed using the MySQL Yum + Repository or by using RPM packages downloaded directly from + Oracle. +

4.4.2.1 Using the MySQL Yum Repository

+ RedHat Enterprise Linux and Oracle Linux platforms can install + Connector/Python using the MySQL Yum repository (see + Adding + the MySQL Yum Repository and + Installing + Additional MySQL Products and Components with Yum). +

Prerequisites

  • + For installing X DevAPI only:Because + the required python3-protobuf RPM + package is not available for Python 3.8 on the RedHat + Enterprise Linux and Oracle Linux platforms, it has to be + manually installed with, for example, pip install + protobuf. This is required for Connector/Python + 8.0.29 or later. +

  • + The mysql-community-client-plugins + package is required for using robust authentication + methods like caching_sha2_password, + which is the default authentication method for MySQL 8.0 + and later. Install it using the Yum repository + 

      $ sudo yum install mysql-community-client-plugins
+
Installation

+ Use the following commands to install Connector/Python: + 

$ sudo yum install mysql-connector-python
+
+# Optionally, install also X DevAPI
+$ sudo yum install mysqlx-connector-python
+

4.4.2.2 Using an RPM Package

+ Connector/Python RPM packages (.rpm files) + are available from the + Connector/Python + download site. +

+ You can verify the integrity and authenticity of the RPM + packages before installing them. To learn more, see + Verifying + Package Integrity Using MD5 Checksums or GnuPG. +

Prerequisites

  • + For installing X DevAPI only:Because + the required python3-protobuf RPM + package is not available for Python 3.8 on the RedHat + Enterprise Linux and Oracle Linux platforms, it has to be + manually installed with, for example, pip install + protobuf. This is required for Connector/Python + 8.0.29 or later. +

  • + The mysql-community-client-plugins + package is required for using robust authentication + methods like caching_sha2_password, + which is the default authentication method for MySQL 8.0 + and later. + 

      $ rpm -i mysql-community-client-plugins-ver.distro.architecture.rpm
Installation

+ To install Connector/Python using the downloaded RPM packages: + 

$ rpm -i mysql-connector-python-ver.distro.architecture.rpm
+
+# Optionally, install X DevAPI
+$ rpm -i mysqlx-connector-python-ver.distro.architecture.rpm
+

4.5 Installing Connector/Python from a Source Distribution

+ Connector/Python source distributions are platform independent. Source + distributions are packaged in two formats:

  • - Zip archive format (.zip file) + Zip archive format + (.zip file)

  • - Compressed tar archive format + Compressed tar archive format (.tar.gz file)

- Either packaging format can be used on any platform, but Zip - archives are more commonly used on Windows systems and - tar archives on Unix and Unix-like systems. -

Prerequisites for Compiling Connector/Python with the C Extension

+ Either of the two packaging formats can be used on any platforms, + but Zip archives are more commonly used on + Windows systems and tar archives on Unix and + Unix-like systems. +

Prerequisites for Compiling Connector/Python with the C Extension

Source distributions include the C Extension that interfaces with - the MySQL C client library. You can build the distribution with or - without support for this extension. To build Connector/Python with support - for the C Extension, you must satisfy the following prerequisites. -

Note

- Python 2.7 support was removed in Connector/Python 8.0.24, and Python 3.7 - support was removed in Connector/Python 8.1.0. -

  • - Linux: A C/C++ compiler, such as gcc -

    - Windows: Current version of Visual Studio -

  • - Protobuf C++ (version >= 4.21.1,<=4.21.12) for the C - extension and/or Python's protobuf package for the pure Python - implementation + the MySQL C client library. You can build the + distribution with or without support for this + extension. To build Connector/Python with support for the C + Extension, the following prerequisites must be satisfied: +

    • + Compiling tools: +

      • + For Linux platforms: A C/C++ + compiler, such as gcc. +

      • + For Windows platforms: Current + version of Visual Studio. +

    • + Python development files.

    • - Python development files + For installing the classic interface + only: MySQL Server binaries (server may be + installed or not installed on the system), including + development files (to obtain the MySQL Server binaries, visit + the + MySQL + download site).

    • - MySQL Server installed, including development files to compile - the optional C Extension that interfaces with the MySQL C - client library -

    - You must install MySQL Server if it is not already present on your - system. To obtain it, visit the - MySQL download site. -

    Installing Connector/Python from Source on Microsoft Windows

    - A Connector/Python Zip archive (.zip file) is available - from the Connector/Python download site (see - Section 4.1, “Obtaining Connector/Python”). + For installing the X DevAPI interface + only: Protobuf C++ (version 4.25.3 or later). +

Installing Connector/Python from Source Code Using + pip

Note

+ We recommend leveraging + python + virtual environments to encapsulate the package + installation instead of installing packages directly into the + Python system environment. +

+ To install Connector/Python from a Zip archive, + download its latest version from the Connector/Python download + site (see + Obtaining + Connector/Python) and follow the steps described below.

- To install Connector/Python from a Zip archive, download the latest version - and follow these steps: + For installing the classic + interface:

  1. - Unpack the Zip archive in the intended installation directory - (for example, C:\mysql-connector\) using - WinZip or another tool that can read - .zip files. + Unpack the Zip archive in a directory of your preference.

  2. - Start a console window and change location to the folder where - you unpacked the Zip archive: - 

    $> cd C:\mysql-connector\
+          Start a terminal and change location to the folder where you
+          unpacked the Zip archive. The unpacked folder should have a
+          layout similar to the following:
+        
        mysql-connector-python-x.y.z-src
+    ├── CHANGES.txt
+    ├── CONTRIBUTING.md
+    ├── LICENSE.txt
+    ├── mysql-connector-python
+    │   ...
+    │   ├── setup.py
+    │   ...
+    ├── pyproject.toml
+    ├── README.rst
+    ├── README.txt
+    └── SECURITY.md

  3. - Inside the Connector/Python folder, perform the installation using this - command: - 

    $> python setup.py install
-

    - To include the C Extension (available as of Connector/Python 2.1.1), use - this command instead: - 

    $> python setup.py install --with-mysql-capi="path_name"
+          Go into the
+          mysql-connector-python-x.y.z-src
+          folder, and perform the installation using this command:
+        
     pip install ./mysql-connector-python
+
    Warning
    
+            DO NOT use mysql-connector-python instead
+            of ./mysql-connector-python, as the
+            former will install the WHEEL package from the PyPI
+            repository, and the latter will install the local WHEEL that
+            is compiled from the source code.
+          
    
+          To include the C Extension, use these
+          steps instead to provide the path to the installation
+          directory of MySQL Server (or to the folder where the server
+          binaries are located) with the MYSQL_CAPI
+          system variable before running the installation step. On Linux
+          platforms:

Installing Connector/Python from Source on Unix and Unix-Like Systems

- For Unix and Unix-like systems such as Linux, Solaris, macOS, and - FreeBSD, a Connector/Python tar archive - (.tar.gz file) is available from the Connector/Python - download site (see Section 4.1, “Obtaining Connector/Python”). -

- To install Connector/Python from a tar archive, download - the latest version (denoted here as - VER), and execute these commands: - 

$> tar xzf mysql-connector-python-VER.tar.gz
-$> cd mysql-connector-python-VER
-
-$> sudo python setup.py install \
---with-protobuf-include-dir=/dir/to/protobuf/include \
---with-protobuf-lib-dir=/dir/to/protobuf/lib \
---with-protoc=/path/to/protoc/binary
-

- To include the C Extension (available as of Connector/Python 2.1.1) that - interfaces with the MySQL C client library, also add the - --with-mysql-capi such as: - 

$> sudo python setup.py install \
-  --with-protobuf-include-dir=/dir/to/protobuf/include \
-  --with-protobuf-lib-dir=/dir/to/protobuf/lib \
-  --with-protoc=/path/to/protoc/binary \
-  --with-mysql-capi="path_name
-

- The argument to --with-mysql-capi is the path to - the installation directory of MySQL Server, or the path to the - mysql_config command. -

- To see all options and commands supported by - setup.py, use this command: - 

$> python setup.py --help

4.4 Verifying Your Connector/Python Installation

- On Windows, the default Connector/Python installation location is - C:\PythonX.Y\Lib\site-packages\, - where X.Y is the Python version you - used to install the connector. -

- On Unix-like systems, the default Connector/Python installation location is + For installing X DevAPI: +

  1. + Unpack the Zip archive in a directory of your preference. +

  2. + Start a terminal and change location to the folder where you + unpacked the Zip archive. The unpacked folder should have a + layout similar to the following: + 

      mysql-connector-python-x.y.z-src
+    ├── CHANGES.txt
+    ├── CONTRIBUTING.md
+    ├── LICENSE.txt
+    ├── mysqlx-connector-python
+    │   ...
+    │   ├── setup.py
+    │   ...
+    ├── pyproject.toml
+    ├── README.rst
+    ├── README.txt
+    └── SECURITY.md
+

  3. + Go into the + mysql-connector-python-x.y.z-src folder, + and perform the installation using this commands: + 

     pip install ./mysqlx-connector-python
+
    Warning

    + DO NOT use mysqlx-connector-python + instead of ./mysqlx-connector-python, as + the former will install the WHEEL package from the PyPI + repository, and the latter will install the local WHEEL that + is compiled from the source code. +

    + To include the Protobuf C-Extension, use + these commands instead on Linux platforms to provide the path + to the folder where the protobuf binaries are located by the + MYSQLXPB_PROTOBUF system variable before + the installation step: + 

     $ export MYSQLXPB_PROTOBUF=<path to protobuf binaries>
+ $ export MYSQLXPB_PROTOBUF_INCLUDE_DIR="${MYSQLXPB_PROTOBUF}/include"
+ $ export MYSQLXPB_PROTOBUF_LIB_DIR="${MYSQLXPB_PROTOBUF}/lib"
+ $ export MYSQLXPB_PROTOC="${MYSQLXPB_PROTOBUF}/bin/protoc"
+ $ pip install ./mysqlx-connector-python
+

    + Or these commands on Windows platforms to provide the path to + the folder where the protobuf binaries are located by the + PROTOBUF system variable before the + installation step: + 

     > $env:PROTOBUF=<path to protobuf binaries>
+ > $env:PROTOBUF_INCLUDE_DIR=$env:PROTOBUF+"\include"
+ > $env:PROTOBUF_LIB_DIR=$env:PROTOBUF+"\lib"
+ > $env:PROTOC=$env:PROTOBUF+"\bin\protoc.exe"
+ > pip install ./mysqlx-connector-python
+
    Note

    + It is not required that the server is actually installed on + the system; for compiling the C-extension, the presence of + libraries are sufficient +

4.6 Verifying Your Connector/Python Installation

Verifying Installations by pip

+ To verify that a Connector/Python package has been installed + successfully using pip, use the following + command: + 

$ pip install list
+

+ If you have installed the classic interface, you should see an + output similar to the following: + 

Package                                  Version
+---------------------------------------- ----------
+...                                      ...
+mysql-connector-python                   x.y.z
+...                                      ...
+

+ If you have installed X DevAPI, you should see an output similar + to the following: + 

Package                                  Version
+---------------------------------------- ----------

+mysqlx-connector-python                   x.y.z
+...
+

Installed from an RPM

+ The default Connector/Python installation location is /prefix/pythonX.Y/site-packages/, where prefix is the location where Python is installed and X.Y is the - Python version. See - How - installation works in the Python manual. + Python version.

The C Extension is installed as - _mysql_connector.so in the + _mysql_connector.so and + _mysqlxpb.so in the site-packages directory, not in the - mysql/connector directory. + mysql/connector and + mysqlx directories for the classic interface + and X DevAPI, respectively. +

Verify the C-extension

+ To verify the C-extension of the classic package is available, run + this command: + 

$ python -c "import mysql.connector; assert mysql.connector.HAVE_CEXT; print(f'C-ext is {mysql.connector.HAVE_CEXT}')"
+

+ If no error is returned, the C-extension has been correctly built + and installed.

- Depending on your platform, the installation path might differ - from the default. If you are not sure where Connector/Python is installed, do - the following to determine its location. The output here shows - installation locations as might be seen on macOS: - 

$> python
->>> from distutils.sysconfig import get_python_lib
-
->>> print get_python_lib()            # Python v2.x
-/Library/Python/2.7/site-packages
-
->>> print(get_python_lib())           # Python v3.x
-/Library/Frameworks/Python.framework/Versions/3.1/lib/python3.1/site-packages
-

- To test that your Connector/Python installation is working and able to - connect to MySQL Server, you can run a very simple program where - you supply the login credentials and host information required for - the connection. For an example, see - Section 5.1, “Connecting to MySQL Using Connector/Python”. -

    Chapter 4 Connector/Python Installation

    Table of Contents

    4.1 Quick Installation Guide
    4.2 Differences Between Binary And Source Distributions
    4.3 Obtaining Connector/Python
    4.4 Installing Connector/Python from a Binary Distribution
    4.4.1 Installing Connector/Python with pip
    4.4.2 Installing by RPMs
    4.5 Installing Connector/Python from a Source Distribution
    4.6 Verifying Your Connector/Python Installation

    + Connector/Python runs on any platform where Python is installed. Make sure + Python is installed on your platform: +

    • + Python comes preinstalled on most Unix and Unix-like systems, + such as Linux, macOS, and FreeBSD. If your system does not have + Python preinstalled for some reasons, use its software + management system to install it. +

    • + For Microsoft Windows, a Python installer is available at the + Python + Download website or via the Microsoft Store. +

    + Also make sure Python in your system path. +

    + Connector/Python includes the classic and X DevAPI APIs, which are + installed separately. Each can be installed by a binary or source + distribution. +

    + Binaries of Connector/Python are distributed in the + RPM + and the + wheel + package formats. The source code, on the other hand, is distributed + as a compressed archive of source files, from which a wheel package + can be built. +

    4.1 Quick Installation Guide

    + The recommended way to install Connector/Python is by + pip and wheel + packages. If your system does not have pip, you + can install it with your system's software manager, or with a + standalone + pip installer. +

    Note

    + You are strongly recommended to use the latest version of + pip to install Connector/Python. Upgrade your + pip version if needed. +

    + Install the Connector/Python interfaces for the classic MySQL + protocol and the X Protocol, respectively, with the following + commands. + 

    # classic API
+$ pip install mysql-connector-python
+
+# X DevAPI
+$ pip install mysqlx-connector-python
+

    + Refer to the + installation + tutorial for alternate means to install X DevAPI. +

    4.2 Differences Between Binary And Source Distributions

    + Installing from a + wheel + (bdist package) is the recommended, except for + Enterprise Linux systems, on which the RPM-based installation + method may be preferred. +

    + Wheels can be directly and easily installed without an extra build + step. However, a wheel package is often specific to a particular + platform and Python version, so there may be cases in which + pip cannot find a suitable wheel package based + on your platform or your Python version. When that happens, you + can get the + source + distribution (sdist) and produce a + wheel package from it for installing Connector/Python. +

    Note

    + Creating a wheel package from an sdist may + fail for some older Python version, as the Connector/Python + source code is only compatible with a specific subset of Python + versions. +

    + In summary, the recommendation is to use a + bdist unless pip cannot find + a suitable wheel package for your setup, or if you need to custom + build a wheel package for some special reasons. +

    Note

    - DMG installer packages were available before Connector/Python 8.1.0. -

    Installing Connector/Python on Linux Using the MySQL Yum Repository

    - EL-based platforms can optionally use RPMs instead of pip, either - by using the - Connector/Python RPM - downloads or by using the MySQL Yum repository (see - Installing Additional MySQL Products and Components with Yum and - Adding the MySQL Yum Repository). -

    RPM Prerequisites

    • - A python3-protobuf RPM package is not - available for Python 3.8 on these platforms, so the dependency - is not part of the RPM specification; instead it must be - manually installed with the likes of pip install - protobuf. This is required as of v8.0.29. -

    • - The mysql-community-client-plugins package - is required to use modern authentication methods, such as - caching_sha2_password, which is the default - authentication method as of MySQL 8.0. - 

    $> sudo yum install mysql-community-client-plugins
-

    - Then install Connector/Python as follows: - 

    $> sudo yum install mysql-connector-python
-

    Installing Connector/Python on Linux Using an RPM Package

    - Connector/Python Linux RPM packages (.rpm files) are - available from the Connector/Python download site (see - Section 4.1, “Obtaining Connector/Python”). -

    - To install a Connector/Python RPM package (denoted here as - PACKAGE.rpm), use - this command: - 

    $> rpm -i PACKAGE.rpm
-

    Prerequisites

    • - A python3-protobuf RPM package is not - available for Python 3.8 on these platforms, so the dependency - is not part of the RPM specification; instead it must be - manually installed with the likes of pip install - protobuf. This is required as of v8.0.29. -

    • - The mysql-community-client-plugins package - is required to use newer authentication methods, such as - caching_sha2_password, which is the default - authentication method as of MySQL 8.0. -

    - RPM provides a feature to verify the integrity and authenticity of - packages before installing them. To learn more, see - Verifying Package Integrity Using MD5 Checksums or GnuPG. -

    4.3 Installing Connector/Python from a Source Distribution

    - Connector/Python source distributions are platform independent and can be - used on any platform. Source distributions are packaged in two - formats: + +# Upgrade X DevAPI +$> pip install mysqlx-connector-python --upgrade + +

    + In case the wheel package you want to install is found in your + local file system (for example, you produced a wheel package + from a source distribution or downloaded it from somewhere), you + can install it as follows: + 

    # Installation
+$ pip install /path/to/wheel/<wheel package name>.whl
+

    Installation of Optional Features

    + Installation from wheels allow you to install optional + dependencies to enable certain features with Connector/Python. + For example: + 

    # 3rd party packages to enable the telemetry functionality are installed
+$ pip install mysql-connector-python[telemetry]
+

    + Similarly, for X DevAPI: + 

    # 3rd party packages to enable the compression functionality are installed
+$ pip install mysqlx-connector-python[compression]
+

    + These installation options are shortcuts to install all the + dependencies needed by some particular features (they are only + for your convenience, and you can always install the required + dependencies for a feature by yourself): +

    • + For the classic protocol: +

      • + dns-srv +

      • + gssapi +

      • + fido2 +

      • + telemetry +

    • + For X Protocol: +

      • + dns-srv +

      • + compression +

    + You can specify a multiple of these options in your installation + command, for example: + +

    $ pip install mysql-connector-python[telemetry,dns-srv,...]

    + + Or, if are installing a wheel package from your local file + system: + +

    $ pip install /path/to/wheel/<wheel package name>.whl[telemetry,dns-srv,...]

    +

    4.4.2 Installing by RPMs

      Installing Connector/Python from Source on Microsoft Windows

      - A Connector/Python Zip archive (.zip file) is available - from the Connector/Python download site (see - Section 4.1, “Obtaining Connector/Python”). + For installing the X DevAPI interface + only: Protobuf C++ (version 4.25.3 or later). +

    Installing Connector/Python from Source Code Using + pip

    Note

    + We recommend leveraging + python + virtual environments to encapsulate the package + installation instead of installing packages directly into the + Python system environment. +

    + To install Connector/Python from a Zip archive, + download its latest version from the Connector/Python download + site (see + Obtaining + Connector/Python) and follow the steps described below.

    - To install Connector/Python from a Zip archive, download the latest version - and follow these steps: + For installing the classic + interface:

    1. - Unpack the Zip archive in the intended installation directory - (for example, C:\mysql-connector\) using - WinZip or another tool that can read - .zip files. + Unpack the Zip archive in a directory of your preference.

    2. - Start a console window and change location to the folder where - you unpacked the Zip archive: - 

      $> cd C:\mysql-connector\
+          Start a terminal and change location to the folder where you
+          unpacked the Zip archive. The unpacked folder should have a

    4.6 Verifying Your Connector/Python Installation

    Verifying Installations by pip

    + To verify that a Connector/Python package has been installed + successfully using pip, use the following + command: + 

    $ pip install list
+

    + If you have installed the classic interface, you should see an + output similar to the following: + 

    Package                                  Version
+---------------------------------------- ----------
+...                                      ...
+mysql-connector-python                   x.y.z
+...                                      ...
+

    + If you have installed X DevAPI, you should see an output similar + to the following: + 

    Package                                  Version

    + The default Connector/Python installation location is /prefix/pythonX.Y/site-packages/, where prefix is the location where Python is installed and X.Y is the - Python version. See - How - installation works in the Python manual. + Python version.

    The C Extension is installed as - _mysql_connector.so in the + _mysql_connector.so and + _mysqlxpb.so in the site-packages directory, not in the - mysql/connector directory. + mysql/connector and + mysqlx directories for the classic interface + and X DevAPI, respectively. +

    Verify the C-extension

    + To verify the C-extension of the classic package is available, run + this command: + 

    $ python -c "import mysql.connector; assert mysql.connector.HAVE_CEXT; print(f'C-ext is {mysql.connector.HAVE_CEXT}')"
+

    + If no error is returned, the C-extension has been correctly built + and installed.

    - Depending on your platform, the installation path might differ - from the default. If you are not sure where Connector/Python is installed, do - the following to determine its location. The output here shows - installation locations as might be seen on macOS: - 

    $> python
->>> from distutils.sysconfig import get_python_lib
-
->>> print get_python_lib()            # Python v2.x
-/Library/Python/2.7/site-packages
-
->>> print(get_python_lib())           # Python v3.x
-/Library/Frameworks/Python.framework/Versions/3.1/lib/python3.1/site-packages
-

    - To test that your Connector/Python installation is working and able to - connect to MySQL Server, you can run a very simple program where - you supply the login credentials and host information required for - the connection.
