mysql is not running, but lock file (/var/lock/subsys/mysql) exists
存在这个问题的一般是由三个原因决定的:
1:配置中的一些文件权限不够,将所有的配置中涉及到的文件全部修改为mysql用户权限
2:mysql运行的pid没有,rm -rf /var/lock/subsys/mysql ,重新创建新的pid文件默认的权限为660
3:my.cnf配置文件错误,需要重新修改
Can‘t open and lock privilege tables: Table ‘mysql.user‘ doesn‘t exist
这个问题是由于myql存放文件中没有系统自带的数据库可以输入mysql_install_db
或者将数据库的路径重新修改为默认的/var/lib/mysql的目录下面
下面贴出我自己的mariadb的配置(从数据库)
