Notes

Note

  • Requires the PyMySQL (Python 2.7 and Python 3.X) or MySQL-python (Python 2.X) package on the remote host. The Python package may be installed with apt-get install python-pymysql (Ubuntu; see apt) or yum install python2-PyMySQL (RHEL/CentOS/Fedora; see yum). You can also use dnf install python2-PyMySQL for newer versions of Fedora; see dnf.
  • Both login_password and login_user are required when you are passing credentials. If none are present, the module will attempt to read the credentials from ~/.my.cnf, and finally fall back to using the MySQL default login of ‘root’ with no password.

Examples

- mysql_variables:
    variable: sync_binlog
