服务器端的 PHP session_start() 错误 [英] PHP session_start () error on server side
问题描述
我目前正在尝试将我的站点从我机器上的本地主机移动到我的 Web 服务器.还有一个问题.
Im currently trying to move my site from localhost on my machine to my web server. And there is one problem.
一切正常，除了用于管理的登录表单.
Everything works fine, except login form for administration.
起初我以为是not-saving-as-utf-8-without-BOM问题，但错误日志显示了一些我以前从未遇到过的奇怪问题.据我了解，问题是关于在服务器上保存会话数据，请参阅下面的错误日志.
At first I thought it was not-saving-as-utf-8-without-BOM problem, but error logs show some strange problem which I never had before. As far as I understand, the problem is about saving session data on server, see error log below.
PHP Warning: session_start() [<a href='function.session-start'>function.session-start</a>]: open(/var/php_sessions/sess_cd9931f63118e645ca5d3704fecf86c6, O_RDWR) failed: No such file or directory (2) in /hermes/bosweb/web273/b2738/ipg.mydomaincom/admin/login.php on line 2

这是我用于 login.php 文档的代码:
Here is the code I use for login.php document:
<?php
session_start ();
require_once 'config/config.php';
$auth = "SELECT username, password FROM admin";
$dbi = mysql_query($auth, $connection);
$row = mysql_fetch_array($dbi);
if($_POST["username"] == $row['username'] && MD5($_POST["password"]) == $row['password'])
{
$_SESSION["Login"] = "true";
header ("Location: index.php");
}
else
{
$_SESSION["Login"] = "false";
//error msg
echo "<html>
<head><title>Failed Login Attempt</title></head>
<body>
Ops! Unlucky guess, try again!
<a href='index.php'>Go Back</a>
</body>
</html>
";
}
?>
推荐答案
第一步，检查目录 /var/php_sessions/ 是否存在并且可以被您的 Web 服务器写入.
first step, check that the directory /var/php_sessions/ exists and is writable by your web server.
