Port not forwarded from vagrant for rails application on host

Having a rails application on the vagrant machine and the 3000 port not being forwarded when you access it form host machine like

http://localhost:3000

if so keep reading

Assuming you have already setup your vagrant machine

Go ahead and open your Vagrant file, find the config.vm.network and update it with

config.vm.network "forwarded_port", guest: 3000, host: 3000

Then make sure you are binding the server with 0.0.0.0 as it is the main problem is being the default 127.0.0.1 for that, when yoiu are instantiation the server do the binding with 0.0.0.0

bin/server --binding=0.0.0.0

Basically the above would tell to listen to almost any ip. This has its own risk if you are doing it on public VM so caution shall be applied. Where as when it is 127.0.0.1, it will be listening to the local address only.

While working with tomcat, you might come across this glitch. Here is how to get rid of it easily.

1. Go to server tab in your eclipse. If you cant see it you can have it through window->show view->servers
2. double click on the tomcat server and you will be directed to page for tomcat configuration.
3. On the page you will see list of ports that the current server is using.
4. Change the HTTP/1.1 from 80 – or whatever it is complaining to new one like 9181.
5. what… you’re done… :)

Happy TomCatting.
