nginx -t 看看配置有没错误
curl 127.0.0.1:9002 看看能不能正常返回
配置完要执行 nginx -s reload 重启 nginx

  [root@iZwz9dkghamwjolg5bhaidZ ~]# nginx -t
  nginx: the configuration file /www/server/nginx/conf/nginx.conf syntax is ok
  nginx: configuration file /www/server/nginx/conf/nginx.conf test is successful
  [root@iZwz9dkghamwjolg5bhaidZ ~]# curl 127.0.0.1:9002
  curl: (7) Failed to connect to 127.0.0.1 port 9002: Connection refused
  
  有做重启操作，不能正常返回

  那就是这个服务没有启动 127.0.0.1:9002
  检测一下这个端口号对不对，或者试试换小一点的端口号，比如 3000

  之前是正确的，改成3000还是不行
  prod.server.js  const port = process.env.PORT || 3000
