To install MySQLdb, please visit sourceforge.net/projects/mysql-python, (for Linux platform, you can visit: pypi.python.org/pypi/MySQL- python) From here you can choose the installation package suitable for your platform, which is divided into precompiled binary files and source code installation packages.

If you choose the binary file release version, the installation process will be completed with basic installation prompts. If you are installing from source code, you need to switch to the top-level directory of the MySQLdb distribution and type the following command:

$ gunzip MySQL-python-1.2.2.tar.gz
$ tar -xvf MySQL-python-1.2.2.tar$ cd MySQL-python-1.2.2$ python setup.py build
$ python setup.py install
