MySQL远程访问权限,允许远程连接的开启

MySQL远程访问权限,允许远程连接的开启

1、登陆mysql数据库   
   mysql -u root -p
   查看user表  www.2cto.com 
mysql> use mysql;
Database changed
mysql> select host,user,password from user;
+--------------+------+-------------------------------------------+
| host         | user | password                                  |
+--------------+------+-------------------------------------------+
| localhost    | root | *A731AEBFB621E354CD41BAF207D884A609E81F5E |
| 192.168.1.1 | root | *A731AEBFB621E354CD41BAF207D884A609E81F5E |
+--------------+------+-------------------------------------------+
2 rows in set (0.00 sec)

   可以看到在user表中已创建的root用户。host字段表示登录的主机,其值可以用IP,也可用主机名,
   (1)有时想用本地IP登录,那么可以将以上的Host值改为自己的Ip即可。

2、实现远程连接(授权法)
   将host字段的值改为%就表示在任何客户端机器上能以root用户登录到mysql服务器,建议在开发时设为%。  
   update user set host = ’%’ where user = ’root’;
   将权限改为ALL PRIVILEGES
mysql> use mysql;
Database changed
mysql> grant all privileges  on *.* to root@'%' identified by "root";
Query OK, 0 rows affected (0.00 sec)  www.2cto.com 
mysql> select host,user,password from user;
+--------------+------+-------------------------------------------+
| host         | user | password                                  |
+--------------+------+-------------------------------------------+
| localhost    | root | *A731AEBFB621E354CD41BAF207D884A609E81F5E |
| 192.168.1.1 | root | *A731AEBFB621E354CD41BAF207D884A609E81F5E |
| %            | root | *A731AEBFB621E354CD41BAF207D884A609E81F5E |
+--------------+------+-------------------------------------------+
3 rows in set (0.00 sec)
这样机器就可以以用户名root密码root远程访问该机器上的MySql.
3、实现远程连接(改表法)
use mysql;
update user set host = '%' where user = 'root';
这样在远端就可以通过root用户访问Mysql.
