Apache的Nginx反向代理 - 錯誤500有時

我是一個nginx新手，我得到了一個headeach服務器配置。我將Nginx配置爲Apache的反向代理，似乎都可以正常工作，但有時會出現錯誤500。Apache的Nginx反向代理 - 錯誤500有時

這裏奇怪的是，後看到錯誤消息500，我刷新頁面，它的工作！錯誤500看起來非常快，只有一秒半，所以我不認爲這是超時問題。

當我測試瀏覽服務器上的網站和頁面時，此問題隨機出現。

隨處搜索，嘗試更改配置，但沒有找到它，所以希望你們都能提供幫助。

下面是配置： 主要nginx的配置 - nginx.conf：

謝謝大家的幫助！

是由nginx的500錯誤，或者它被阿帕奇引起的，通過nginx的通過呢？ –

最後一天，當我僅通過瀏覽http：// site：8989來測試apache方面時，有時會出現錯誤。所以我認爲它是由Apache引起的。 – user2514868

我剛纔也發現，**這個問題似乎出現在我運行fcgid模式時**。當我改用cgi模式時，這個問題似乎就出來了。 **但是當用cgi模式運行時，CPU負載會增加，這會使服務器很快拒絕請求** :-(。所以我必須回到fcgid模式，這個問題仍然沒有解決 - 有時候內部服務器錯誤500。 – user2514868

我相信你會發現你的問題/var/log/.../abc.xyz.com_error_log文件
