centos 7 nginx不接受来自外部网络的请求

我在 centos 7 上配置了一个 Nginx 服务器,它可以从服务器上的浏览器正常运行。但是当我从任何远程客户端尝试时,它说无法连接。我尝试将 http 添加到防火墙服务中。

    sudo firewall-cmd --add-port=80/tcp --permanent

结果是:

 target: default
  icmp-block-inversion: no
  interfaces: ens192
  sources: 
  services: dhcpv6-client ssh http https
  ports: 80/tcp 443/tcp 8000/tcp
  protocols: 
  masquerade: no
  forward-ports: 
  source-ports: 
  icmp-blocks: 
  rich rules:

但是当我从另一个节点尝试时:

sudo  nmap -sT  {ip address}

我有:

PORT    STATE  SERVICE
22/tcp  open   ssh
443/tcp closed https

如果有帮助的话,结果

sudo netstat -tulpn
