在安裝完Nginx后服務啟動失敗的解決辦法

systemctl start nginx //啟動服務
Job for nginx.service failed because the control process exited with error code. See “systemctl status nginx.service” and “journalctl -xe” for details. //提示信息

問題分析

然后我就按照問題提示的命令查看了一下 journalctl -xe
8月 09 00:38:21 localhost.localdomain nginx[26205]: nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Addre
8月 09 00:38:22 localhost.localdomain nginx[26205]: nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Addre
8月 09 00:38:22 localhost.localdomain nginx[26205]: nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Addre
8月 09 00:38:23 localhost.localdomain nginx[26205]: nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Addre
8月 09 00:38:23 localhost.localdomain systemd[1]: nginx.service: control process exited, code=exited stat
8月 09 00:38:23 localhost.localdomain nginx[26205]: nginx: [emerg] still could not bind()
8月 09 00:38:23 localhost.localdomain systemd[1]: Failed to start nginx.
從輸出的提示信息上可以看到”0.0.0.0:80 failed”字樣，大概可能跟端口有關，然后再使用如下命令查看一下端口進程：

通過監聽端口，發現80端口已經被占用了，怪不得Nginx服務起不來

解決辦法

[root@promote nginx-1.12.2]# killall -s QUIT nginx

重啟啟動一下nginx
