開啓MySQL遠程訪問權限 容許遠程鏈接

一、登錄mysql數據庫    

   mysql -u root -p

   查看user表

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)

 

   能夠看到在user表中已建立的root用戶。host字段表示登陸的主機，其值能夠用IP，也可用主機名，

   (1)有時想用本地IP登陸，那麼能夠將以上的Host值改成本身的Ip便可。

二、實現遠程鏈接(受權法)

   將host字段的值改成%就表示在任何客戶端機器上能以root用戶登陸到mysql服務器，建議在開發時設爲%。   
   update user set host = ’%’ where user = ’root’;

   將權限改成ALL PRIVILEGES

mysql> use mysql;
Database changed
mysql> grant all privileges  on *.* to root@'%' identified by "password";
Query OK, 0 rows affected (0.00 sec)

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

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)

這樣機器就能夠以用戶名root密碼root遠程訪問該機器上的MySql.

三、實現遠程鏈接（改表法）

use mysql;

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

這樣在遠端就能夠經過root用戶訪問Mysql.
