DNS 查找失敗：

我用 virtualmin 安裝了我的伺服器，我正在使用 apache 和 php fpm。當我嘗試打開我的網站時，出現此錯誤：

代理錯誤

代理伺服器收到來自上游伺服器的無效響應。代理伺服器無法處理請求 GET /index.php。

原因：DNS 查找失敗：

在“for:”之後是空的

這是我為該站點提供的 apache2 conf 文件：

謝謝

SetHandler傳遞給 UNIX 域套接字的指令格式錯誤。

它應如文件所示：

SetHandler "proxy:unix:/var/run/154262472926263.sock|fcgi://localhost/"

請記住，您已將其放置在配置中的兩個位置。

另請記住，您可能還有其他配置問題，這些問題在這裡並不明顯。
