Redirecting to /bin/systemctl status mysql.service
● mysql.service
Loaded: not-found (Reason: No such file or directory)

[root@ansible flask_sqlalchemy]# service mysql start
Redirecting to /bin/systemctl start mysql.service

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
解决方法:
# yum install mariadb-server -y
# systemctl start mariadb.service
# systemctl enable mariadb.service
# mysql
