# mysql -uroot
mysql> use mysql;
Database changed
mysql> SELECT `Host`,`User` FROM `user`;
+-----------+--------+
| Host      | User   |
+-----------+--------+
| 127.0.0.1 | houtai |
| 127.0.0.1 | root   |
| ::1       | root   |
| localhost | houtai |
| localhost | root   |
+-----------+--------+
5 rows in set (0.00 sec)

mysql> UPDATE `user` SET `Host` = '%' WHERE `User` = 'root' LIMIT 1;
Query OK, 1 row affected (0.00 sec)
Rows matched: 1  Changed: 1  Warnings: 0

mysql> SELECT `Host`,`User` FROM `user`;
+-----------+--------+
| Host      | User   |
+-----------+--------+
| %         | root   |
| 127.0.0.1 | houtai |
| 127.0.0.1 | root   |
| ::1       | root   |
| localhost | houtai |
+-----------+--------+
5 rows in set (0.00 sec)

mysql> flush privileges;

远程写个PHP脚本测试：

php
$con = mysqli_connect("IP","root","密码");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

 else echo"connect ok!"
?>

服务器要关闭防火墙： iptables -F  (service iptables stop)

显示： connect ok!
