推荐答案

您可以使用ip表将端口80映射到8000

you can use ip tables to map port 80 to 8000

iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8000

使其永久化

sudo sh -c "iptables-save > /etc/iptables.rules"

并添加

pre-up iptables-restore < /etc/iptables.rules

到您的/etc/network/interfaces

to your /etc/network/interfaces
