1.查看nginx状态

systemctl status nginx

状态如果是Active: active (running)则是正常的

[root@hcss-ecs-9b96 ~]# systemctl status nginx
● nginx.service - The nginx HTTP and reverse proxy server
   Loaded: loaded (/usr/lib/systemd/system/nginx.service; disabled; vendor preset: disabled)
   Active: active (running) since Wed 2024-11-13 13:41:11 CST; 16min ago
  Process: 603696 ExecStart=/usr/sbin/nginx (code=exited, status=0/SUCCESS)
  Process: 603639 ExecStartPre=/usr/sbin/nginx -t (code=exited, status=0/SUCCESS)
  Process: 603637 ExecStartPre=/usr/bin/rm -f /run/nginx.pid (code=exited, status=0/SUCCESS)
 Main PID: 603699 (nginx)
    Tasks: 3 (limit: 11427)
   Memory: 16.9M
   CGroup: /system.slice/nginx.service
           ├─603699 nginx: master process /usr/sbin/nginx
           ├─603700 nginx: worker process
           └─603701 nginx: worker process

2.查看Nginx进程

如果Nginx正在运行，您还可以使用ps命令来查看Nginx进程

ps aux | grep nginx

3.检查Nginx配置文件是否正确无误

nginx -t

4.查看Nginx的版本

nginx -v
# 如果查看更详细
nginx -V

5.修改nginx配置

vim /etc/nginx/nginx.conf

增加容器端口8090指向域名

server {
      listen 80;
      server_name www.tieyongjie.cn;  # 替换为您的域名
​
      location / {
         proxy_pass http://localhost:8090;  # 指向Docker容器的端口8080
         proxy_set_header Host $host;
         proxy_set_header X-Real-IP $remote_addr;
    }

6. 设置开机自启动

# 设置 nginx 开机自启动
systemctl enable nginx
# 验证
systemctl is-enabled nginx

输出如下即表示开机自启动设置成功

[root@hcss-ecs-9b96 ~]# systemctl enable nginx
Created symlink /etc/systemd/system/multi-user.target.wants/nginx.service → /usr/lib/systemd/system/nginx.service.
[root@hcss-ecs-9b96 ~]# systemctl is-enabled nginx
enabled
