CentOS6.8下MySQL数据库忘记root密码解决方法

一、更改my.cnf配置文件

编辑/etc/my.cnf文件,在[mysqld]下添加skip-grant-tables,保存退出。


重启mysql服务:services mysqld restart


二、更改root密码

重启mysqld服务后,执行mysql命令,进入mysql命令行:


[root@yeebian ~]# mysql
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 2

修改root密码

mysql> UPDATE mysql.user SET Password=PASSWORD('mysqladmin') where USER='root';
Query OK, 0 rows affected (0.00 sec)
Rows matched: 3  Changed: 0  Warnings: 0
 
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
 
mysql> exit
Bye
三、删除/etc/my.cnf中的skip-grant-tables,或者注释掉,重启mysql即可。
