CentOS下mysql忘记root密码解决办法

        最近接手服务器，没人知道数据库密码。

        遇到这种情况如何处理

        1，停止mysql服务

            service mysqld stop

        2，修改配置文件/etc/my.cnf

            在[mysqld]下添加skip-grant-tables

            意思是忽略密码

            保存并退出

        3，启动Mysql

            service mysql start

         4，修改密码

            mysql

            Welcome to the MySQL monitor. Commands end with ; or \g.

            Your MySQL connection id is 3 to server version: 3.23.56
            Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
            mysql> USE mysql ;
            Database changed
            mysql> UPDATE user SET Password = password ( 'new-password' ) WHERE User = 'root' ;
            Query OK, 0 rows affected (0.00 sec)
            Rows matched: 2 Changed: 0 Warnings: 0
            mysql> flush privileges ;
            Query OK, 0 rows affected (0.01 sec)

            mysql> quit

        5，改回配置，重启服务

            service mysqld restart
