学习CentOS
Linux的时候经常会忘记各种密码,本文主要说明在使用CentOS的过程中,忘记MySQL数据库密码的解决办法。
第一步:通过如下代码,停止MySQL服务器的运行
Stopping MySQL: [ OK ]
第二步:使用 “–skip-grant-tables”参数重新启动mysql
[root@CentOs5 ~]# mysqld_safe --skip-grant-tables &[1] 23810
[root@CentOs5 ~]# Starting mysqld daemon with databases from /var/lib/mysql
第三步:用帐号登录MySQL
[root@CentOs5 ~]# mysql -u rootWelcome to the MySQL monitor. Commands end with ; or g.
Your MySQL connection id is 1
Server version: 5.0.77 Source distribution
Type 'help;' or 'h' for help. Type 'c' to clear the buffer.
第四步:改变用户数据库表
mysql> use mysqlReading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
第五步:修改密码,记得密码要用password()函数进行加密,一定不要忘记!不然,
mysql> update user set password=password('admin123') where user='root';Query OK, 1 row affected (0.04 sec)
Rows matched: 1 Changed: 1 Warnings: 0
第六步:刷新权限表
mysql> flush previleges;ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'previleges' at line 1
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
第七步:退出mysql
mysql> quitBye
第八步:对mysql进行重启
[root@CentOs5 ~]# service mysqld restart;STOPPING server from pid file /var/run/mysqld/mysqld.pid
100421 13:44:03 mysqld ended
Stopping MySQL: [ OK ]
Starting MySQL: [ OK ]
[1]+ Done mysqld_safe --skip-grant-tables
第九步:用更改过的密码重新登录即可。
[root@CentOs5 ~]# mysql -u root -pEnter password: admin123
Welcome to the MySQL monitor. Commands end with ; or g.
Your MySQL connection id is 2
Server version: 5.0.77 Source distribution
