重新啓動NGINX失敗

我在Ubuntu 16.04上安裝了NGINX並編輯了我的配置。當我想用sudo service nginx restart重新啓動我的錯誤：重新啓動NGINX失敗

Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.

的nginx.service狀態的內容：

爲什麼我不能重新啓動我的nginx的實例？我不明白爲什麼它是阻斷重啓

錯誤信息的重要組成部分，是

bind() to 0.0.0.0:80 failed (98: Address already in use)

因此，在啓動時，nginx的無法綁定到端口80，因爲其他一些程序已經綁定到這個端口。當其他程序退出或取消綁定此套接字時，您將只能啓動nginx。

要找到哪個程序當前綁定這個端口，可以爲根的（sudo如）運行此命令：

ss -ntlp "sport = :80"

當我執行，我得到：'國家的Recv-Q發送-Q本地地址：端口對端地址：端口 LISTEN 0 128 *：80 *：* LISTEN 0 128 ::: 80 ::: *' – sesc360

請務必以root身份運行程序。普通用戶沒有權限檢查哪個程序綁定到某個端口。 –

好的，所以現在的輸出是 'State Recv-Q Send-Q Local Address：Port Peer Address：Port LISTEN 0 128 *：80 *：* users：（（「nginx」，pid = 26359，fd = （「nginx」，pid = 26359，fd = 7），（「nginx」，pid = 26358，fd = 6）） LISTEN 0 128 ::: 80 ::: * users：，pid = 26358，fd = 7））' – sesc360
