Access web server on VirtualBox/Vagrant machine from host browser?

I have a Django web server on a VirtualBox/Vagrant machine running Ubuntu.

I have followed this guide to create a Django project: https://docs.djangoproject.com/en/dev/intro/tutorial01/

I have a web server running at http://127.0.0.1:8000/ inside my guest machine. This is the first time I am running a Django web server. It is supposed to be a hello world app.

How can I access this web application from my host browser?

I have tried running ifconfig in the guest to get the IP that I should visit I found a promising IP address in inet addr.

But I have tried entering the following into my host browser and it didn't work. http://inetaddrnumbers:8000/

How can I access the web server from my browser?

Try this.

1. Open the vagrant file (should be in the directory where you specified to create the new vagrant machine).
2. Search for config.vm.network. If you didn't set up the file earlier, it should be commented-out.
3. Change it to look something like this: config.vm.network "private_network", ip: "55.55.55.5". Here the IP address (55.55.55.5) can be any IP address you want.
4. Now log out from the vagrant machine, and reload your vagrant machine by the command vagrant reload.
5. Ssh again to your vagrant machine and restart your django server by the command python manage.py runserver 0.0.0.0:80. Again, the port address (80) can be 8000 if you want it so.
6. After that, in your browser, enter the address 55.55.55.5, and hopefully you should see your web app.

Now if you would like to go further, you can edit your host file, and add this line:

55.55.55.5 mynewdomain.com

Then, in your browser, enter the following address:

mynewdomain.com

And you should see your web app. Note that www is not added in the domain name inside the host file, so only mynewdomain.com can be accessed by hostname. You can, however, add it.

55.55.55.5 mynewdomain.com www.mynewdomain.com

Hope this helps. Cheers
