问题描述

当我尝试连接到数据库时，出现此错误:

When I try to connect to my databases, I get this error:

Lost connection to MySQL server at 'reading initial communication packet', system error:111

这是我的PHP代码(仅是测试):

Here is my PHP code (it's just a test):

<?php
@session_start(); 
include(".conf.php");
print_r($conf);
$con = mysql_connect($conf['db_hostname'], $conf['db_username'], $conf['db_password']) or die (mysql_error());
mysql_select_db("aTableName", $con);
$prof = '000';
//$prof = $_GET['profile'];
$prof = addslashes(htmlentities($prof));
$result = "SELECT * FROM aTableName WHERE id = '$prof'";
$q = mysql_query($result, $con);
$qarr = mysql_fetch_array($q);
print_r($qarr); 
?>

推荐答案

您的主机错误，端口错误，防火墙阻止了连接或SQL Server未运行. 111是连接被拒绝".您可以尝试通过telnet到SQL Server的主机和端口进行故障排除.如果可行，则您的代码会使主机或端口错误.

Your host is wrong, your port is wrong, a firewall blocked the connection, or the SQL server is not running. 111 is "connection refused". You can troubleshoot by trying to telnet to the SQL server's host and port. If that works, your code gets the host or port wrong.

如果这不起作用，请检查SQL Server本身.如果在那里工作，则问题出在网络上.如果无法正常运行，则表明SQL Server未运行.

If that doesn't work, check on the SQL server itself. If it works there, the problem is the network. If it doesn't work there, the SQL server is not running.
