Notes

Note

  • Requires the PyMySQL (Python 2.7 and Python 3.X) or MySQL-python (Python 2.X) Python package on the remote host. For Ubuntu, this is as easy as apt-get install python-pymysql. (See apt.) For CentOS/Fedora, this is as easy as yum install python2-PyMySQL. (See yum.)
  • 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

# Check for sync_binlog setting
- mysql_variables:
    variable: sync_binlog

# Set read_only variable to 1
