Ubuntu 16.04.Когда я пробовал 'sudo service mysql restart', у меня был результат:
Job for mysql.service failed because the control process exited with error code. See "systemctl status mysql.service" and "journalctl -xe" for details.
service mysql status:

Ранее я пыталсяизменить кодировку текста по умолчанию на utf-8:
sudo nano /etc/mysql/conf.d/utf8_set.cnf
Теперь у меня было это (в файле)
[mysqld]
default-character-set=utf8
[client]
default-character-set=utf8
Я не мог правильно отключить mysql, потому что не мог понятькак выйти.Ввод '\ e' мне не поможет
