Question

我在机器上安装了nginx，并且安装正确，但是无法在机器上启动nginx，每当我尝试启动nginx时，都会显示以下错误。每当我运行命令systemctl restart nginx && systemctl status nginx时我收到错误消息：

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

执行命令后：systemctl status nginx.service

以下输出是产生的：

  `nginx.service - The NGINX HTTP and reverse proxy server
   Loaded: loaded (/lib/systemd/system/nginx.service; disabled; vendor 
   preset: e Active: failed (Result: exit-code) since Mon 2018-09-10 
  14:57:14 IST;32s ago Process: 6321 ExecStartPre=/usr/sbin/nginx -t 
  (code=exited ,status=203/EXEC)`

执行命令后： journalctl -xe，生成的输出为：

为此寻找解决方案，但没有找到任何解决方案。任何帮助将不胜感激。

Answer 1

就像最后一个错误说您正在使用端口80一样，请检查端口80上是否有Apache

有用的命令：

netstat -tlpn

无法启动nginx
