长时间登录vps,然后mysql的密码忘记了。。。。so,百度之,记录一下
1.首先确认服务器出于安全的状态,也就是没有人能够任意地连接MySQL数据库。因为在重新设置MySQL的root密码的期间,MySQL数据库完全出于没有密码保护的状态下,其他的用户也可以任意地登录和修改MySQL的信息。自己的vps也没人知道,应该是安全状态。
2.修改MySQL的登录设置:
#vim /etc/my.conf eg:
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
skip-grant-tables
保存并且退出vim
3.重启mysqld
# /etc/init.d/mysqld restart
Stopping MySQL: [ OK ]
Starting MySQL: [ OK ]
4.
4.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
5.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。
6.重新启动mysqld
# /etc/init.d/mysqld restart
Stopping MySQL: [ OK ]
Starting MySQL: [ OK ]
