如何对在同一服务器上运行的不同进程使用不同的域名

Question

Assume I have three different sites running. Node.js app on port 3000, Apache/PHP on port 80, and then a Go app on port 5000.

How can I have three different domain names that go to each port?

I was thinking of a basic route system on port 80 that all domains refer to, then the program looks at url and redirects to correct port. Is that recommended? Is there a better way?

Thanks

If you're already using Nginx, you can very easily set up named-based reverse proxy vhosts for the apps that aren't on port 80:

server {
    listen *:80;
    server_name nodeapp.mydomain.com;
    location / {
        proxy_pass http://localhost:3000;
    }
}

server {
    listen *:80;
    server_name goapp.mydomain.com;
    location / {
        proxy_pass http://localhost:5000;
    }
}
