mysql 遠程訪問的

不少時間應用與數據庫是分開架設的，這樣能夠提供良好的訪問速度的。

詳細配置以下：

mysql> USE mysql; 
mysql> SELECT User, Password, Host FROM user; 
+------+----------+-----------+
| User | Password | Host      |
+------+----------+-----------+
| root |          | localhost |
+------+----------+-----------+ 


mysql> -- 只有一個默認的 root 用戶, 密碼爲空, 只容許 localhost 鏈接
mysql> -- 下面咱們另外添加一個新的 root 用戶, 密碼爲空, 只容許 192.168.1.100 鏈接

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.1.100' IDENTIFIED BY '' WITH GRANT OPTION;
mysql> flush privileges;

Query OK, 0 rows affected (0.00 sec)

mysql> SELECT User, Password, Host FROM user;
+------+-------------------------------------------+---------------+
| User | Password                               | Host              |
+------+-------------------------------------------+---------------+
| root | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 | localhost   |

| root | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 | 127.0.0.1      |
| root |                                              | 192.168.4.101 |
+------+-------------------------------------------+----------------+
