Услуги Mysql - Не запуск

Я - новичок к Ubuntu, и я нашел, что mysql снижается без любого обновления. Ниже команда, которую я использую, и она заканчивается. Любая ссылка или совет высоко ценятся.

sudo /etc/init.d/mysql start
[....] Starting mysql (via systemctl): mysql.serviceJob for mysql.service failed because the control process exited with error code. See "systemctl status mysql.service" and "journalctl -xe" for details.
 failed!
