用 SSH客户端登录上以后

首先启动数据库：

[root@iZm5ec880z2rorZ ~]# service mysqld start

可以输入一下加粗命令：
[root@iZm5ec880z2rorZ ~]#  mysql -u root -p 
Enter password: （输入你的数据库密码）
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 5

mysql> commit;

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql>  exit;

退出后，输入下边的命令：
[root@iZm5ec880z2rorZ ~]# service mysqld restart
Shutting down MySQL...                                     [  OK  ]
Starting MySQL.                                            [  OK  ]


然后在本地输入自己设置的密码（这里是 ldyu123）就可以连接上来了
