我在Ubuntu 16.04上安装了NGINX并编辑了我的配置 . 当我想用 sudo service nginx restart 重启时，我收到错误：
nginx.service的作业失败，因为控制进程退出并显示错误代码 . 有关详细信息，请参阅“systemctl status nginx.service”和“journalctl -xe” .
nginx.service状态的内容是：
nginx.service - A high performance web server and a reverse proxy server

为什么我不能重新启动我的nginx实例？我不明白为什么阻止重启

错误消息的重要部分是
因此，在启动时，nginx无法绑定到端口80，因为某些其他程序已绑定到此端口 . 当其他程序从此套接字退出或解除绑定时，您将只能启动nginx .
要查找当前绑定此端口的程序，可以以root身份运行此命令（例如，使用
sudo）：当您在与apache在同一台机器上运行apache服务器时，通常会出现此问题，并且nginx需要运行相同的端口，即80.尝试将nginx端口更改为8080或其他内容 . ie {listen 8080 default_server; listen [::]：8080 default_server;}并重新启动nginx
