Vagrant入门——同步文件及文件夹(Synced Folders)

While it is cool to have a virtual machine so easily, not many people want to edit files using just plain terminal-based editors over SSH. Luckily with Vagrant you don't have to. By using synced folders, Vagrant will automatically sync your files to and from the guest machine.

By default, Vagrant shares your project directory (remember, that is the one with the Vagrantfile) to the /vagrant directory in your guest machine. Run vagrant upagain and SSH into your machine to see:

$ vagrant up
...
$ vagrant ssh
...
vagrant@precise32:~$ ls /vagrant
Vagrantfile

Believe it or not, that Vagrantfile you see inside the virtual machine is actually the same Vagrantfile that is on your actual host machine. Go ahead and touch a file to prove it to yourself:

vagrant@precise32:~$ touch /vagrant/foo
vagrant@precise32:~$ exit
$ ls
foo Vagrantfile

Whoa! "foo" is now on your host machine. As you can see, Vagrant kept the folders in sync.

With synced folders, you can continue to use your own editor on your host machine and have the files sync into the guest machine.
