在 Fedora 24 上,Web 服务器 (Node.js) 在端口 5000 上运行(独立,无 apache/nginx)。 http://本地主机:5000作品
如何让80端口可以访问呢?
试过这个
systemctl restart firewalld
firewall-cmd --add-service=http --permanent
firewall-cmd --add-masquerade --permanent
firewall-cmd --add-forward-port=port=80:proto=tcp:toport=5000
firewall-cmd --list-all

sources:

附加信息 也尝试使用 --zone=external 进行上述所有操作
在端口 80 上以 root 身份运行节点是可行的。请注意,没有 IPv4:
netstat -tpln

答案1
firewall-cmd --add-service=http --permanent
firewall-cmd --add-service=https --permanent
firewall-cmd --add-masquerade --permanent
firewall-cmd --add-forward-port=port=80:proto=tcp:toport=5000 --permanent
#make port forwarding work on localhost
iptables -t nat -I OUTPUT --source 127.0.0.1 --destination 127.0.0.1 -p tcp --dport 80 -j REDIRECT --to-ports 5000
答案2
firewall-cmd --reload
设置永久规则后不要忘记运行。否则,在重新启动服务之前不会读取规则firewalld
。
