Ubuntu under python2.7 link MySQL

The previous time in learning the basics of Python, where to operate MySQL, but always error:

Mysql_exceptions. Operationalerror: (2002, "Can ' t connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock ' (2)")

Baidu for a long time, can solve the problem.

The above error indicates that Python defaults to/var/run/mysqld/mysqld.sock for MySQL Mysqld.sock, but Ubuntu is generated by default in/tmp/mysql.sock, so it can be ln-s/tmp/via a soft connection Mysql.sock/var/run/mysqld/mysqld.sock

However, due to Mysql.sock in the TMP directory, so the Mysql.sock will be automatically deleted after shutdown, which will cause the soft link is also deleted, after the boot and generate a new mysql.sock, so to re-link to the soft chain.

Search for a long time, want to solve the shutdown after the automatic removal of Mysql.sock method, but are unsuccessful.
