apache沒有啓動，日誌上沒有正確的消息

Question

我試圖用puppet配置apache。當我嘗試啓動Apache時，出現任何錯誤消息都會失敗。我不知道它爲什麼失敗。我嘗試執行下面的命令，它只是說啓動失敗，並沒有顯示啓動失敗的具體原因。你能讓我知道如何弄清楚發生了什麼？我在下面附上我的日誌文件。

systemctl status httpd.service 
journalctl -xe

Answer 1

我覺得你最好的提示是

Aug 15 22:56:03 hostname httpd[18999]: no listening sockets available, shutting down 

看起來像另一個過程是，Tomcat是試圖監聽套接字，默認爲8080，或者您可以檢查的conf看什麼傾聽設置

可以使用命令狀

lsof -i TCP |grep 8080 

要得到的是什麼進程id在該端口上偵聽並在top或其他任何地方追蹤它

Answer 2

我能夠找出問題，puppet的默認配置已經在httpd.conf中註釋了監聽端口並添加了一個port.conf。但是，因爲我沒有明確配置偵聽端口，所以apache沒有偵聽的默認端口。我配置了端口並開始工作。
