如何连接到网络上另一台计算机上主机上的mysql [英] how to connect to mysql on host on another computer on network

问题描述

对于

$conn = mysql_connect("192.168.0.235", "root", "") or
    die("Could not connect: " . mysql_error());

mysql_select_db("crossdomaintest");

$result = mysql_query("SELECT * FROM testing");

while ($row = mysql_fetch_array($result, MYSQL_NUM)) {
    echo $row[1].$row[2].$row[3]."<br/>"; 
}

mysql_free_result($result);

我得到

警告:mysql_connect()[function.mysql-connect]:不允许主机"192.168.0.167"连接到第3行的/var/www/test.php中的此MySQL服务器 无法连接:不允许主机"192.168.0.167"连接到该MySQL服务器

Warning: mysql_connect() [function.mysql-connect]: Host '192.168.0.167' is not allowed to connect to this MySQL server in /var/www/test.php on line 3 Could not connect: Host '192.168.0.167' is not allowed to connect to this MySQL server

我的IP是192.168.0.168，我在Ubuntu 10.10上使用LAMP，而192.168.0.235在windows 7上使用XAMPP，我可以访问...235上的所有站点，但不能从本地服务器访问数据库

And my IP is 192.168.0.168 and I am using LAMP on Ubuntu 10.10 and 192.168.0.235 is using XAMPP on windows 7 i can access all sites on ...235 but not access database from my local-server.

有什么想法吗?

推荐答案

这与如何连接"无关.连接将完全相同.
关于如何设置远程服务器以允许来自IP的连接.
您在192.168.0.235上的数据库服务器上具有root特权吗?如果是这样，则必须在其上运行适当的GRANT PRIVILEGES查询.
如果不是，请让数据库管理员这样做

it's not about "how to connect". connecting would be all the same.
it's about how to setup remote server to allow connections from your IP.
do you have root privileges on the db server on 192.168.0.235? if so, you have to run appropriate GRANT PRIVILEGES query on it.
If not - ask a db admin to do that

我还建议不要使用root用户访问远程数据库.更好地创建另一个用户并给他适当的权限

I'd also advise not to use root user to access remote database. Better create another user and give him appropriate privileges
