1 修改MySQL的登录设置


 

# vi /etc/my.cnf 


在[mysqld]的中加上一句:skip-grant-tables 

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‘ ;

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。
