当我尝试通过远程 MySQL 服务器上的本地计算机的 shell 进行连接时，我可以成功连接：

> mysql -h remotehost -u myuser -p
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.

但是当我尝试使用 PHP 脚本连接时

$serverName = "remotehost"; // here I put the actual IP address
$userName = "myuser";
$passCode = "actualpassword";
mysql_connect($serverName,$userName,$passCode);

我收到以下错误

警告：mysql_connect()：用户“myuser”@“localhost”的访问被拒绝（使用密码：是）

远程MySQL服务器版本为5.1.52，本机PHP版本为5.3.10-1ubuntu3.4

我发现了一个类似的问题，但答案并没有解决我的问题： problem connected to remote mysql database using php

我真的很感激一些帮助！

Use SHOW GRANTS to see if the user you are trying to login with has permission to connect from the web server's IP or domain name.

mysql> SHOW GRANTS;
+----------------------------------------------------------------------------------------------------------------------------------------+
| Grants for root@localhost                                                                                                              |
+----------------------------------------------------------------------------------------------------------------------------------------+
| GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY PASSWORD '*6381FFD48B21F7ED17AE12AF4F8BE4458F4B0AC7' WITH GRANT OPTION |
+----------------------------------------------------------------------------------------------------------------------------------------+

Use the GRANT command to give remote access to your web user, so to speak. Something like this. 

mysql> GRANT SELECT ON database.table TO 'myuser'@'web_server_IP_or_domain_name' IDENTIFIED BY 'actualPassword';

Reference the MySQL 5.1 manual for exact syntax. MySQL 5.1 Manual: GRANT

您需要允许远程访问 mySQL（在您拥有 mySQL 数据库的服务器上）。如果您使用的是 CPanel 或 Plesk，您可以在控制面板中进行操作。我遇到了这个问题，显然 mySQL 默认配置是只允许本地主机。

您需要授予该用户访问权限，以便您的服务器的 IP 地址可以访问该用户。MySQL 用户经常被锁定到本地主机。

一个快速的方法是查看表mysql.users并查看该用户是否被锁定到本地主机。

有许多不错的 GUI 可以帮助添加主机，但最手动的方法可能是向数据库添加另一行。您可以将主机更改为 '%' 以进行测试，但这会打开一些东西并且不太安全。

您是否发布了实际代码？如果是这样，您忘记将字符串括在引号中：

$serverName = "remotehost"; // here I put the actual IP address
$userName   = "myuser";
$passCode   = "actualpassword";
mysql_connect($serverName,$userName,$passCode);

在继续之前，请确认 $serverName 变量确实是远程地址，主机名或 IP 地址。然后...
