Fedroa Linux开启局域网8080端口访问

尝试开启8080端口
–zone #作用域
–add-port=8080/tcp #添加端口，格式为：端口/通讯协议
–permanent #永久生效，没有此参数设置，重启后会失效。

[root@cvallis Downloads]# firewall-cmd  --permanent --zone=public --add-port=8080/tcp

报错：找不到firewall命令

Traceback (most recent call last):
  File "/usr/bin/firewall-cmd", line 31, in <module>
    from firewall.client import FirewallClient, FirewallClientIPSetSettings, \
ModuleNotFoundError: No module named 'firewall'

安装第三方命令firewall

[Lay@cvallis Downloads]$ sudo dnf install python3-firewall

尝试开启8080端口，报错：firewalld未启动

[Lay@cvallis Downloads]$ sudo firewall-cmd --zone=public --add-port=8080/tcp --permanent
FirewallD is not running

修改Tornado服务配置文件

    'application': {  # 应用配置
        'ip': '192.168.31.137',  # 应用绑定端口
        'port': 8080,  # 应用端口
        }
