mysql 远程连接数据库的二种方法

一、连接远程数据库：

1、显示密码

如：MySQL 连接远程数据库（192.168.5.116），端口“3306”，用户名为“root”，密码“123456”

C:/>mysql -h 192.168.5.116 -P 3306 -u root -p123456

2、隐藏密码

如：MySQL 连接本地数据库，用户名为“root”，

C:/>mysql -h localhost -u root -p 
Enter password:

二、配置mysql允许远程链接

默认情况下，mysql帐号不允许从远程登陆，只能在localhost登录。本文提供了二种方法设置mysql可以通过远程主机进行连接。

一、改表法

    在localhost登入mysql后，更改 "mysql" 数据库里的 "user" 表里的 "host" 项，将"localhost"改称"%"

例如：

#mysql -u root -p

Enter password:

……

mysql>

　　mysql>update user set host = '%' where user = 'root';

　　mysql>select host, user from user;

二、授权法

    例如： 你想myuser使用mypassword（密码）从任何主机连接到mysql服务器的话。

　　mysql>GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%'IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

　　如果你想允许用户myuser从ip为192.168.1.6的主机连接到mysql服务器，并使用mypassword作为密码

　　mysql>GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.3'IDENTIFIED BY

　　'mypassword' WITH GRANT OPTION;

   mysql>FLUSH PRIVILEGES

　　使修改生效，就可以了

常见问题： 
1、在采用法二授权法之后，无法在本地登录mysql（如：#mysql -u root -p -h 192.168.5.116
Enter password: 
ERROR 1045 (28000): Access denied for user 'root'@'loadb116' (using password: YES)
上例中loadb116是主机名.
解决方法： 
1、这时可以使用：mysql  -u root -p 登录，进入到mysql后。
mysql> grant all privileges on *.* to 'root'@'loadb116' 
       identified by '123456' with grant option; 
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges; 
Query OK, 0 rows affected (0.00 sec)
2、在本地使用ip地址登录
# mysql -u root -p -h 192.168.5.116 
Enter password:
