Interacting with a vagrant box

SSH

The most common way of interacting with a vagrant box is through ssh. Once the box is up you can connect to it from your local terminal. Remember to be in the directory of you virtual box before doing anything. In my case it's ~/vagrant/centos65i686. Just type:
vagrant ssh

Synced Folders

The folder you used to launch your vagrant session, the one which contains Vagrantfile, can be accessed from you box after you have begun your ssh session as /vagrant. E.g.
vagrant ssh
ls /vagrant
would return Vagrantfile
During the next section titled 'Provisioning' we'll add a line to the Vagrant file to sync folders which enable the process of developing web content.

Provisioning

Vagrant can automatically install software when you vagrant up so that the guest machine can be repeatably created and ready-to-use. E.g.
Create bootstrap.sh in the same directory as your Vagrantfile with these contents.
#!/usr/bin/env bash
apt-get update
apt-get install -y apache2
Next, add these line to your Vagrantfile:
config.vm.synced_folder '.', "/var/www"
config.vm.provision :shell, path: "bootstrap.sh"
Once this is done, you'll need to reload the vagrant session and make sure that the provisioning is used thus:
vagrant reload --provision
If you're starting a session from scratch:
vagrant up --provision
will do.

Port Forwarding

During the provisioning stage we installed an Apache server. We also set up a synced folder so that whatever we had in our /vagrant folder could be served.
Port forwarding allows you to access a port on your own machine, but actually have all the network traffic forwarded to a specific port on the guest machine.
To achieve this add the following line to your Vagrantfile:
config.vm.network :forwarded_port, guest: 80, host: 4567
Then reload your session:
vagrant reload --provision
Now you should be able to access your box directory through your browser using the following URL
http://localhost:4567

When you want to finish your ssh session, just type
logout
If I mess up
If you make a bunch of changes which mess things up, don't worry. You can return the box to its original state by typing
vagrant destroy
