    Centos下忘记mysql的root密码的解决方法

    一:(停掉正在运行的mysql)
    [root@NetDakVPS ~]# service mysql stop
    二:使用 “--skip-grant-tables”参数重新启动mysql
    [root@NetDakVPS ~]# mysqld_safe --skip-grant-tables &

    [1] 23810
    Starting mysqld daemon with databases from /var/lib/mysql
    三:用root帐号登录mysql
    [root@NetDakVPS ~]# mysql -u root
    Welcome to the MySQL monitor. Commands end with ; or g.
    Your MySQL connection id is 1
    Server version: 5.0.77 Source distributionType 'help;' or 'h' for help. Type 'c' to clear the buffer.
    四:改变用户数据库
    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 -ADatabase changed
    五:修改密码,记得密码要用password()函数进行加密
    mysql> update user set password=password('netdak') where user='root';
    Query OK, 1 row affected (0.04 sec)
    Rows matched: 1 Changed: 1 Warnings: 0
    六:刷新权限表
    mysql> flush privileges;
    Query OK, 0 rows affected (0.00 sec)
    七:退出mysql
    mysql> quit
    Bye
    八:对mysql进行重启
    [root@NetDakVPS ~]# service mysql restart;
    STOPPING server from pid file /var/run/mysqld/mysqld.pid
    100421 13:44:03 mysqld endedStopping MySQL: [ OK ]
    Starting MySQL: [ OK ]
    [1]+ Done mysqld_safe --skip-grant-tables
    九:用更改过的密码重新登录即可。
    [root@NetDakVPS ~]# mysql -u root -p
    Enter password: netdak
    Welcome to the MySQL monitor. Commands end with ; or g.
    Your MySQL connection id is 2
    Server version: 5.0.77 Source distributionType 'help;' or 'h' for help. Type 'c' to clear the buffer.mysql> quit
    Bye

    十、重新执行修改密码

    SET PASSWORD = PASSWORD('123456');

    注:第十步不一定需要,但是 MySql5.6操作时可能会报错:You must SET PASSWORD before executing this statement.
