centos 修改mysql密码

1．修改MySQL的登录设置：

?

1	# vim /etc/my.cnf

加上一句：skip-grant-tables

 

2．重启mysql

?

1 2 3

# service mysqld restart Stopping MySQL: [ OK ] Starting MySQL: [ OK ]

3．修改密码

这里要注意 ，本人尝试很多次都报错，命令找不到 ，解决办法是 去/usr/local/bin
去执行命令即可

?

1 2 3 4 5 6 7 8

mysql> USE mysql ; Database changed mysql> UPDATE user SET Password = password ( '新密码' ) 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

4．修改刚刚改过的配置文件

?

1	# vim /etc/my.cnf

5.重启mysql

?

1 2 3

# service mysqld restart Stopping MySQL: [ OK ] Starting MySQL: [ OK ]
