Apache的Nginx反向代理 - 错误500有时

我是一个nginx新手，我得到了一个headeach服务器配置。我将Nginx配置为Apache的反向代理，似乎都可以正常工作，但有时会出现错误500。Apache的Nginx反向代理 - 错误500有时

这里奇怪的是，后看到错误消息500，我刷新页面，它的工作！错误500看起来非常快，只有一秒半，所以我不认为这是超时问题。

当我测试浏览服务器上的网站和页面时，此问题随机出现。

随处搜索，尝试更改配置，但没有找到它，所以希望你们都能提供帮助。

下面是配置： 主要nginx的配置 - nginx.conf：

    location/{

    location ~ \.php$ { 
     proxy_pass http://127.0.0.1:8989;

具有上述问题的服务器 - /conf.d /myvhost.conf：

server { 
    listen  IP:80; ssl off; 
    server_name abc.xyz.com; 

    access_log /home/myvhost/logs/nginx_access.log;

     root /home/myvhost/public_html;

    location ~ /\.ht {

}

的apache配置：

在所有配置我粘贴在这里，IP是我的虚拟主机的IP地址。

谢谢大家的帮助！

是由nginx的500错误，或者它被阿帕奇引起的，通过nginx的通过呢？ –

最后一天，当我仅通过浏览http：// site：8989来测试apache方面时，有时会出现错误。所以我认为它是由Apache引起的。 – user2514868

我刚才也发现，**这个问题似乎出现在我运行fcgid模式时**。当我改用cgi模式时，这个问题似乎就出来了。 **但是当用cgi模式运行时，CPU负载会增加，这会使服务器很快拒绝请求** :-(。所以我必须回到fcgid模式，这个问题仍然没有解决 - 有时候内部服务器错误500。 – user2514868

我相信你会发现你的问题/var/log/.../abc.xyz.com_error_log文件
