[root@oraserver139 ~]# mysql -uroot -p
Enter password:
ERROR 1045 （28000）: Access denied for user "root"@"localhost" （using password: NO）

查看当前安装的mysql版本：

停止mysql服务：
[root@oraserver139 ~]# service mysql stop
Shutting down MySQL.. SUCCESS！

进入到skip-grant-tables模式：

[root@oraserver139 ~]# mysqld_safe --skip-grant-tables
