问题描述

• 由于误操作，将mysql的mysql库删除，导致数据库启动异常，mysql启动报错，报错如下

2018-10-11 16:30:11 2995 [ERROR] Fatal error: Can't open and lock privilege tables: Table 'mysql.user' doesn't exist
181011 16:30:11 mysqld_safe mysqld from pid file /export/servers/data/mysql/3306/pid/mysql.pid ended

 

解决方法

• 从别的环境拷贝  user.frm       user.MYD       user.MYI 这三个文件

cd /export/servers/data/mysql/3306/data/mysql/

ls user.*
  user.frm       user.MYD       user.MYI

 

• 拷贝到报错的环境
• 更改权限

cd /export/servers/data/mysql/3306/data/mysql/

chmod admin.admin user.*

chmod 775 user.*

 

再次启动即可
