Apache-2.2
（nginx）Apache Forbidden錯誤（隨機）：沒有錯誤日誌
我正在執行 Nginx 伺服器，但最近我隨機收到 Apache 的“禁止”錯誤，而且它似乎永遠不會在“第一次”訪問時發生，只有在刷新/瀏覽一段時間後才會發生。
更重要的是，我對 httpd 的“指定”錯誤日誌
(/var/etc/httpd/logs/error_log and /var/logs/httpd/....)是空的。我想它們應該是空的，因為我正在執行 NGINX，但是 Apache 顯示了錯誤，所以我認為它應該一開始就在這裡。但是我後來才知道httpd是不活動的。我指定的 Nginx 日誌工作。通過
www.example.com(virtual.conf) 訪問我的伺服器，我可以看到訪問和錯誤日誌。錯誤日誌顯示了一些與此問題無關的隨機內容。通過 IP (default.conf) 訪問我的站點，我得到了訪問日誌，但錯誤日誌是空的。
所以我認為這個問題不是由 NGINX 引起的，HTTPD 被“禁用”，但是在瀏覽了一段時間後，我在任何頁面上都出現了隨機的“禁止”Apache 錯誤。
附加資訊
我將硬/軟 ulimit 都提高到 166384，重新啟動伺服器等。Apache 出於某種原因以root身份執行（這很奇怪，因為我提到httpd顯示為“已禁用”）。
Nginx default.conf（通過IP訪問伺服器的配置）

我現在至少看到了一些錯誤。這是audit.log。第一行顯示頁面載入成功。第二個是當我收到“禁止”消息時會發生什麼。

這篇文章旨在告訴您不要相信您的 ISP，因為他們在三週內重複“他們這邊一切正常”。
我在使用 Putty 時收到此錯誤。
The server's host key does not match the one PuTTY has cached in the registry.事實證明，我的 ISP 的另一個客戶端不小心將我的 IP 設置為他們自己的 IP，因此有兩台機器連接到一個 IP。它還解釋了 Apache 錯誤——它是由不同的伺服器提供的。
