CLI Use(mchb command)

mchb command

Send the heartbeat related command.
You can issue the following commands: heartbeat configuration listing, heartbeat configuration, heartbeat modification, cluster name modification, and heartbeat port modification.

When you install MCCS, the initial user account ID is set to 'admin' and the password is set to 'password'.
When you run the CLI command, you need to enter the ID and the password. Otherwise, the above initial ID and password will be used.
Thus, when you change the initial user password, you must enter the ID/password in the CLI command as options.
