Erro de Inicialização MariaDB

SQL MySQL Linux MariaDB

Bom dia/Boa tarde/ Boa noite!

Utilizo o MariaDB como o banco de dados do GLPI, recentemente o programa começou a apresentar erro de desconexão com banco. Após fazer uma análise do que estava ocorrendo, encontrei um erro com o serviço do MariaDB, sendo ele: 

root@SVGLPI:~# sudo service mysqld start
Job for mariadb.service failed because of unavailable resources or another system error.
See "systemctl status mariadb.service" and "journalctl -xe" for details.


A principio o erro foi resolvido renomeando o arquivo ib_logfile0 de log do MySql em /var/lib/mysql/, porem o problema foi resolvido por um dia, no outro voltou a ocorrer e não funcionou mais. vou deixar o resultado do "systemctl status mariadb.service" and "journalctl -xe" abaixo, alguem pode me dar uma luz?

A primeira mensagem estava clara:

mar 14 13:46:48 SVGLPI systemd[1]: Failed to start MariaDB 10.5.23 database ser>
mar 14 13:51:11 SVGLPI systemd[1]: mariadb.service: Found left-over process 734>

O serviço do banco já estava no ar, através do processo 734.

Depois, no log, vemos que ocorreu um restart:

mar 14 00:29:20 SVGLPI systemd[1]: Stopped MariaDB 10.5.23 database server.
mar 14 00:29:20 SVGLPI systemd[1]: mariadb.service: Consumed 5min 7.735s CPU time.
mar 14 00:29:20 SVGLPI systemd[1]: Starting MariaDB 10.5.23 database server...
mar 14 00:29:27 SVGLPI systemd[1]: Started MariaDB 10.5.23 database server.
mar 14 00:29:27 SVGLPI /etc/mysql/debian-start[282250]: Upgrading MySQL tables if necessary.

O banco foi parado e reiniciado, novamente, aparentemente com sucesso.

Porém, ao acessar o banco com o usuário root@localhost, faltam permissões:

mar 14 01:27:05 SVGLPI /etc/mysql/debian-start[283869]: Checking for insecure root accounts.
mar 14 01:27:05 SVGLPI debian-start[283872]: ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: N>

Aí parece que alguém deu um kill no processo do banco:

mar 14 01:26:55 SVGLPI systemd[1]: mariadb.service: Main process exited, code=killed, status=6/ABRT
mar 14 01:26:55 SVGLPI systemd[1]: mariadb.service: Failed with result 'signal'.
mar 14 01:26:55 SVGLPI systemd[1]: mariadb.service: Consumed 5min 35.439s CPU time.
mar 14 01:27:00 SVGLPI systemd[1]: mariadb.service: Scheduled restart job, restart counter is at 261.
mar 14 01:27:00 SVGLPI systemd[1]: Stopped MariaDB 10.5.23 database server.

Não sei se é o seu caso, mas pode ser que o usuário "root@localhost" tenha sido excluído e, por isso, não esteja funcionando.
