标签:mysql   install   db   

运行环境:centos 7

数据库:mariadb

问题描述:在yum安装mariadb数据库运行后运行了/var/lib/mysql_install_db命令,从而导致mariadb数据库启动或重启都失败。

故障解决:

[centos@centos mysql]$ sudo systemctl start mariadb.service  
Job for mariadb.service failed because the control process exited with error code. See "systemctl status mariadb.service" and "journalctl -xe" for details.

通过问题描述,首先想到的是运行sudo journalctl -xe 查看以下问题详细信息,但是经查看并没有比较详细的error描述,使我想到了/var/log/mariadb/error.log,经查看获取了以下错误信息,mysqld: File ‘./mysql-bin.000013‘ not found (Errcode: 13),根据提示,查看到底是不是mysql-bin.000013二进制日志文件丢失,ls -l /var/lib/mysql/经查看此文件存在,但却发现此文件的属主与属主和其他文件属主与属组权限不一样,改其属主和属组 sudo chown mysql.mysql mysql-bin.000013,重新启动mariadb问题得以解决。

总结:

在linux下大多数故障的发生都有日志文件的记录,遇到问题不要惊慌,首先查看问题描述,然后通过日志文件描述来解决问题。不要盲目网上查答案。
