Node.js application wont start on my public IP

Question

I'm SSHing into a linux shell for a school project. Right now, we're trying to set up a react app for a web frontend. We were able to run the app on localhost easily enough, and all of the functionality seems to be good, but I can't figure out how to get this hosted on the public IP of the computer. We've been using yarn to do all of this, though i've tried other things, so here's some cli output.

path/to/thing# yarn start
yarn run v1.22.5
$ react-scripts start
Attempting to bind to HOST environment variable: public.facing.ip.address        //This is a website name
If this was unintentional, check that you haven't mistakenly set it in your shell.

Could not find an open port at public.facing.ip.address.
Network error message: listen EADDRNOTAVAIL: address not available public.facing.ip.address  //numeric

error Command failed with exit code 1.

root@computer:path/to/thing# 

When I run hostname -I, public.facing.ip.address does not appear at all. So that seems like the obvious issue. The catch here is that we are also running jenkins on a separate port of public.facing.ip.address from this same computer. That was much easier to set up, it just came as something I could start as a service using 'systemctl start jenkins' and up it went onto the public facing IP. I set all that up and I can access it just fine, etc. The best I can do with this is modify the HOST variable either in the terminal or the .env file, then yarn starts a development server on localhost (which I can't access since I'm on a different network SSHing into this computer)

How do I make yarn host our webapp on the public facing IP?

Answer 1

打开您的路由器页面，某处应该有 dmz 主机选项，将其指向您的本地 IP 地址

Answer 2

My networking inexperience was the culprit. Instead of using HOST=path.to.public.ip, the solution was to use HOST=0.0.0.0.
