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

Notes

Note

  • Requires the MySQLdb Python package on the remote host. For Ubuntu, this is as easy as apt-get install python-mysqldb. (See apt.) For CentOS/Fedora, this is as easy as yum install MySQL-python. (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.

Status

This module is flagged as preview which means that it is not guaranteed to have a backwards compatible interface.
