因为放寒假家里没有宽带,便很少上网,前几天用手机进入自己的个人博客时竟然返回数据库不能连接的错误,吓我一跳,网站肯定被人黑了,但转头一想我的博客就几篇破文章,谁这么无聊要黑,我并没有立刻去网上找解决的办法,因为手机不能连接服务器。今天打开电脑第一件事就是要解决这个问题,我确定我的mysql登录密码没有写错,但是不明白为什么一直报这样的错: Access denied for user 'root'@'localhost' (using password:YES) 索性我就改一下登录密码试试,在网上搜了搜,一位园友的方法解决了这个问题:

方法:
1.修改MySQL的登录设置:
# 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 ]
