Question

我使用api解析xml，每隔30分钟用cronjob解析xml，我突然发现我无法再连接到服务器了。我的测试得到了这个错误：

failed to open stream HTTP request failed

我做了什么：

contact to server provider -> they have no idea
ping to server -> works fine
check by file_get_contents('http://ip.xx/ and http://domian.xx') -> the same error
checked with curl -> still no success
check from localhost -> everything work fine
used get_headers() -> no luck
used gethostbyname('domain') -> successful returns ip
checked allow_url_fopen -> is 1
checked file_get_content through other random domains -> work
changed dns settings in resolve.conf from default to publick -> no luck
disabled directadmin csf -> nothing changed

a也使用了这段代码

$curl = curl_init();
curl_setopt_array($curl, array(    
    CURLOPT_URL => $url,
    CURLOPT_HEADER => true,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_NOBODY => true));

$header = explode("\n", curl_exec($curl));
curl_close($curl);

它返回

    Array ( 
[0] => HTTP/1.1 200 OK 
[1] => Date: Sun, 10 Aug 2014 08:42:07 GMT 
[2] => Server: Apache/2 
[3] => X-Powered-By: PHP/5.4.24 
[4] => Cache-Control: no-cache 
[5] => Pragma: no-cache 
[6] => Set-Cookie: irsp_admin_sessionhash=eb1aeff7a65ff9bfde01658804a56245; path=/; domain=.87.107.52.147 
[7] => Set-Cookie: irsp_user_sessionhash=b8878e85b41e47bbcf162c7a74a4f4f6; path=/; domain=.87.107.52.147 
[8] => Set-Cookie: irsp_invalidsignin=deleted; expires=Thu, 01-Jan-1970 00:00:01 GMT; path=/; domain=.87.107.52.147
[9] => Vary: User-Agent 
[10] => Content-Type: text/html 
[11] => 
[12] => )

最后我改变了我们服务器的IP地址 - ＆gt;没有变化（它从xxx.xx.xxx.48变为xxx.xx.xxx.49）

然而，该服务器上有一个目录，它有一个不同的作业（http // ip ** / api **）我可以连接到那个

服务器信息是：

第5.3.24节 Apache 2.2.22

任何建议？

显然MTU出了问题。使用下面的ssh命令修复了问题

ip link set dev venet0:0 mtu 1350

无法打开流HTTP请求失败 - soap - getheader - file_get_contents
