Ruby on Rails: http://localhost:3000 not working

Question

Machines:

• VM Machine (Ruby on Rails Server) - 192.168.1.37
• Host Machine (Machine where the VM resides) - 192.168.1.38
• Remote Machine (Dev Machine) - 192.168.1.36

Notes

• VM Machine is running Cent OS (console only)
• Host Machine is running Windows 7
• VM emulator is Virtual Box
• Remote Machine is Running on Windows 10

Pre-requisite

• Added 192.168.1.37 as localhost in the Host Machine host file
• start the rails service bundle exec rails s -p 3000

Problem

• accessing site http://localhost:3000 NOT working
• accessing site https://192.168.1.37:3000 working

What Is Needed

• Access the site via http://locahost:3000

Quirks

• It works on remote machines running Linux (changed the host file to point to VM Machine as localhost)

Answer 1

why do you insist to visit the site via localhost:3000? as you are running the app under vm, if you want to access the webpage from another pc/mac via ip, you have to forward the local port to the vm port via nat, or let the vm to own a ip from your local network.

As you can access the webpage via https://192.168.1.37:3000, rails is running, there's nothing to do with rails configurations.

Answer 2

Rails 4 binds on localhost by default, so you will need to bind to 0.0.0.0, if you want the page to be accessible from another machine.

Start your rails server like this:

bundle exec rails s -p 3000 -b 0.0.0.0
