It was possible to install mysql in the source code of Ubuntu 12.04 after a step-by-step tutorial on the official website, but mysql won't work after Python-MySQLdb is installed.

I have been working on this for a few days. It was possible to install mysql in the source code of Ubuntu 12.04 following the tutorials on the official website step by step. However, after installing Python-MySQLdb, mysql would not work, when it is started, The "the MySQL server quit without updating The PID file (/usr/local/bin/mysql/data/XXXXX. pid "error or" MySQL server cannot be found (/usr/bin/mysqld_safe) "error.

It was later found that it was a/etc/mysql/my. the cnf file is generated after Python-MySQLdb is installed, unless you install mysql to copy the my-default.cnf to this location. The content of the/etc/mysql/my. cnf file after Python-MySQLdb is installed should be as follows:

#
# The MySQL database server configuration file.
#
# You can copy this to one:
#-"/Etc/mysql/my. cnf" to set global options,
#-"~ /. My. cnf "to set user-specific options.
#
# One can use all long options that the program supports.
# Run program with -- help to get a list of available options and
# -- Print-defaults to see which it wocould actually understand and use.
