Ubuntu查看nginx运行状态

你可以使用以下命令来查看 Nginx 运行状态：

1. 查看 Nginx 服务是否在运行：

sudo systemctl status nginx

如果 Nginx 正在运行，你应该会看到输出类似如下的信息：

● nginx.service - A high performance web server and a reverse proxy server
   Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled)
   Active: active (running) since Mon 2021-05-31 20:18:51 UTC; 1 weeks 0 days ago
     Docs: man:nginx(8)
  Process: 1668 ExecStart=/usr/sbin/nginx -g daemon on; master_process on; (code=exited, status=0/SUCCESS)
  Process: 1664 ExecStartPre=/usr/sbin/nginx -t -q -g daemon on; master_process on; (code=exited, status=0/SUCCESS)
 Main PID: 1672 (nginx)
    Tasks: 2 (limit: 1146)
   Memory: 2.9M
   CGroup: /system.slice/nginx.service
           ├─1672 nginx: master process /usr/sbin/nginx -g daemon on; master_process on;
           └─1673 nginx: worker process

2. 查看 Nginx 监听的端口：

sudo netstat -tulpn | grep nginx

这将会列出所有正在监听的端口，如果 Nginx 正在监听 80 和 443 端口，你应该会看到类似如下的输出：

tcp6       0      0 :::80                   :::*                    LISTEN      1672/nginx: master process /usr/sbin/nginx -g daemon on; master_process on;
tcp6       0      0 :::443                  :::*                    LISTEN      1672/nginx: master process /usr/sbin/nginx -g daemon on; master_process on;
