Direct access method without 8080
problem
Generally, the websites we visit are all domain names without port numbers. How did he achieve it?
After purchasing the dns resolver and domain name, you need to add the port number to access the website you deployed
Solution
Map 80 of the system to port 8080
iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080
When starting the project again, it can be used without the port number
