3.4.2.5. Tips and Tricks

We can use the --discover-slaves-login option for mysqlrpladmin in order to detect the slaves automatically instead of manually specifying the slaves.

The mysqlrpladmin utility allows users to specify a script to execute before and after the failover and switchover operations using the --exec-before and --exec-after options respectively. Note that the script specified using the exec-after option only runs in case the switchover/failover executes successfully.

We can use the mysqlrpladmin utility to start and stop all the slaves with the start/stop commands. Using the stop command only stops servers that are actually slaves of the specified master thus preventing us from stopping unwanted servers.
