    1.修改

    # vi /etc/my.cnf 
    在[mysqld]的段中加上一句:skip-grant-tables 
    例如: 
    [mysqld] 
    datadir=/var/lib/mysql 
    socket=/var/lib/mysql/mysql.sock 
    skip-grant-tables 
    保存并且退出vi。 
    2.重新启动mysqld 
    # /etc/init.d/mysqld restart 
    Stopping MySQL: [ OK ] 
    Starting MySQL: [ OK ] 
    3.登录并修改MySQL的root密码 
    # /usr/bin/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 ; 
    Reading table information for completion of table and column names 
    You can turn off this feature to get a quicker startup with -A 
    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 
    Bye 
    4.将MySQL的登录设置修改回来 
    # vi /etc/my.cnf 
    将刚才在[mysqld]的段中加上的skip-grant-tables删除 
    保存并且退出vi。 
    5.重新启动mysqld 
    # /etc/init.d/mysqld restart 
    Stopping MySQL: [ OK ] 
    Starting MySQL: [ OK ]
