在 Fedora 24 上,Web 服务器 (Node.js) 正在端口 5000 上运行(独立,无 apache/其他)。尝试使其可在端口 80 上访问。
尝试过这个:
systemctl stop firewalld
iptables -t nat -F
iptables -t mangle -F
iptables -F
iptables -X
iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-ports 5000
http://localhost不起作用
尝试过这个
systemctl restart firewalld
firewall-cmd --add-service=http --permanent
firewall-cmd --zone=external --add-masquerade
firewall-cmd --zone=external --add-forward-port=port=80:proto=tcp:toport=5000
firewall-cmd --add-forward-port=port=80:proto=tcp:toport=5000
firewall-cmd --list-all

对于其他人来说它只是有效: Best practices when running Node.js with port 80 (Ubuntu / Linode)
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
