重置MySQL root密码

今天复习同步的时候，忘了测试机的root密码，重置了一下，过程如下:

[root@localhost ~]# mysql -uroot -pyxgtest;
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

 

[root@localhost ~]# service mysql stop
Shutting down MySQL...[确定]
[root@localhost ~]# mysqld_safe --skip-grant-tables &

100809 17:15:09 mysqld_safe mysqld from pid file /var/lib/mysql//localhost.localdomain.pid ended

 

 

[root@localhost ~]# mysql -u root
