Linux MySQL密码修改

 

1)如果您没有忘记密码的情况下,可以通过UPDATE直接编辑user表来修改密码:

进入数据库mysql -u root

mysql> use mysql;

mysql> UPDATE user SET Password = PASSWORD('newpass') WHERE user = 'root';

mysql> FLUSH PRIVILEGES;

或者 

 /etc/init.d/mysql stop 

 /etc/init.d/mysql start

 

2)如果您已经忘记密码:

# /etc/init.d/mysql stop                                   1、结束当前正在运行的mysql进程。

# /usr/bin/mysqld_safe --skip-grant-tables     2、用mysql安全模式运行并跳过权限验证。

# mysql -u root                                               3、重开一个终端以root身份登录mysql。

 

 

mysql> use mysql;                                          4、修改root用户口令。

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('root') where User ='root';

Query OK, 3 rows affected (0.00 sec)

Rows matched: 3 Changed: 3 Warnings: 0

 

 

mysql> exit

 

 

# /etc/init.d/mysql restart                                5、结束mysql安全模式,用正常模式运行mysql。

mysql> update mysql.user set password=PASSWORD('新密码') where User='root'; 

                                                                       6、试试你新修改的口令

mysql> flush privileges;

mysql> quit
