mysql 远程访问的

不少时间应用与数据库是分开架设的，这样能够提供良好的访问速度的。

详细配置以下：

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


mysql> -- 只有一个默认的 root 用户, 密码为空, 只容许 localhost 链接
mysql> -- 下面咱们另外添加一个新的 root 用户, 密码为空, 只容许 192.168.1.100 链接

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