What is the error when starting mysql?

Question

MySQL

When starting mysql, it gives the following error (or what is it?)
[email protected]:~# service mysql restart
stop: Unknown instance:
mysql start/running, process 6228
when I go to the site, this error appears:
[Bitrix\Main\DB\SqlQueryException]
Mysql query error: Unknown storage engine 'InnoDB' (400)
SELECT o.SITE_ID, o.MODULE_ID, o.NAME, o.VALUE FROM b_option o
site on Bitrix if anything.
