Subject: How to stop the whole system gracefully ?


My system is installed using kola-ansible.

The database was inconsistent due to the last unexpected shutdown, and the
system could not start normally, which was very troublesome. 

I would like to ask what command should be used to shut down the entire
system gracefully in an emergency ?
