O Mariadb não inicia: Falha no registro do InnoDB como um mecanismo de armazenamento

0

Eu instalei mariadb no meu PC. Mas não vai começar o serviço. O comando sudo systemctl mariadb.start retorna o erro -

Job for mariadb.service failed because the control process exited with error code. See "systemctl status mariadb.service" and "journalctl -xe" for details.

O status de mariadb.service é reconhecido

Also,

  • I can't find any file name my.cnf on my system.
  • I have installed it using dnf not yum.
  • mysql -u root -p returns ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (111 "Connection refused").
