Script for Master-Slave automation.
unfixed Error => slave server can't run if configured through mysql_replication. need to run manually via cli in slave server with command : CHANGE MASTER TO MASTER_HOST = '{{host_ip}}', MASTER_USER = 'dbrep', MASTER_PASSWORD = 'dbrep', MASTER_LOG_FILE = '{{log_id}}', MASTER_LOG_POS = {{pos_id}}
