[Prabhakaran Karuppaih]

- name: Override variables for MySQL (RedHat).
set_fact:
mysql_daemon: mysqld
mysql_packages: ['mysql-server']
mysql_log_error: /var/log/mysqld.err
mysql_syslog_tag: mysqld
mysql_pid_file: /var/run/mysqld/mysqld.pid
mysql_socket: /var/lib/mysql/mysql.sock
when: ansible_os_family == "RedHat"
-

The above codes are present in starfish.yml file..

Instead of ansible commands, How to do it directly on mysql-python itself.

Please Help.
