4. Start mysql service and add boot start mysql Service

# Add start cp support-files/mysql. server/etc/init. d/mysql
# Start mysql
Service mysql start

An error is reported during startup.

Because the/var/log/mariadb Folder does not exist, we create

mkdir /var/log/mariadb && chown mysql.mysql /var/log/mariadb && sudo -u mysql touch /var/log/mariadb/mariadb.log

Restart

service mysql start
