# 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.)

Note

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.
