At this point we have a web server up and running with the ability to modify files from our host and have them automatically synced to the guest. However, accessing the web pages simply from the terminal from inside the machine is not very satisfying. In this step, we’ll use Vagrant’s networking features to give us additional options for accessing the machine from our host machine.

1.接口设置

One option is to use port forwarding. Port forwarding allows you to specify ports on the guest machine to share via a port on the host machine. This 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.

Let’s setup a forwarded port so we can access Apache in our guest. Doing so is a simple edit to the Vagrantfile, which now looks like this:

Vagrant.configure(“2”) do |config|
config.vm.box = “precise32”
config.vm.provision :shell, :path => “bootstrap.sh”
config.vm.network :forwarded_port, host: 4567, guest: 80
end

Run a vagrant reload or vagrant up (depending on if the machine is already running) so that these changes can take effect.

Once the machine is running again, load http://127.0.0.1:4567 in your browser. You should see a web page that is being served from the virtual machine that was automatically setup by Vagrant.

2.其他网络配置

Vagrant also has other forms of networking, allowing you to assign a static IP address to the guest machine, or to bridge the guest machine onto an existing network. If you’re interested in other options, read the networking page.
