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

# Stop mysql slave thread
- mysql_replication:
    mode: stopslave

# Get master binlog file name and binlog position
- mysql_replication:
    mode: getmaster

# Change master to master server 192.0.2.1 and use binary log 'mysql-bin.000009' with position 4578
- mysql_replication:
    mode: changemaster
    master_host: 192.0.2.1
    master_log_file: mysql-bin.000009
    master_log_pos: 4578

# Check slave status using port 3308
- mysql_replication:
    mode: getslave
    login_host: ansible.example.com
    login_port: 3308
