使用PHP的MySQL连接字符串教程

我正在尝试通过本地计算机连接到服务器上托管的数据库.

我的服务器具有cPanel 11,它是典型的共享服务器,由CentOS,PHP和MySQL提供支持.

确切地说,我将转销商帐户保存在同一服务器中.我想访问不同帐户或域之间的数据库.

在MySQL连接字符串中,我尝试定义域名,但是它不起作用.这是我尝试过的.

<?php
$link = mysql_connect('mydomain.com', 'mysql_user', 'mysql_password');
if (!$link) {
    die('Could not connect: ' . mysql_error());
}
echo 'Connected successfully';
mysql_close($link);
?>

这给出了以下错误

Warning: mysql_connect() [function.mysql-connect]: [2002] A connection attempt failed because the connected party did not (trying to connect via tcp://bhatkalnews.com:3306) in C:\wamp\www\test\conn.php on line 4

Warning: mysql_connect() [function.mysql-connect]: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. in C:\wamp\www\test\conn.php on line 4

Fatal error: Maximum execution time of 60 seconds exceeded in C:\wamp\www\test\conn.php on line 4

我必须在连接字符串中定义什么才能使其正常工作？

解决方法:

防火墙？

尝试

telnet mydomain.com 3306

在命令行上.

如果这样不起作用,则说明该连接已被防火墙阻止
