VagrantでCentOS7.1の環境を構築

# 1. Boxファイルの取得

```
$ vagrant box add centos71 https://github.com/CommanderK5/packer-centos-template/releases/download/0.7.1/vagrant-centos-7.1.box
==> box: Box file was not detected as metadata. Adding it directly...
==> box: Adding box 'centos71' (v0) for provider: 
    box: Downloading: https://github.com/CommanderK5/packer-centos-template/releases/download/0.7.1/vagrant-centos-7.1.box
==> box: Successfully added box 'centos71' (v0) for 'virtualbox'!
```

# 2. 仮想マシンの初期化

```
$ mkdir centos71vm
$ cd centos71vm
$ vagrant init centos71
A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
`vagrantup.com` for more information on using Vagrant.
```

# 3. 仮想マシンへのログイン
* 仮想マシンの起動

```
$ vagrant up
Bringing machine 'default' up with 'virtualbox' provider...
==> default: Importing base box 'centos71'...
==> default: Matching MAC address for NAT networking...
==> default: Setting the name of the VM: centos71vm_default_1455940191858_56370
==> default: Clearing any previously set network interfaces...
==> default: Preparing network interfaces based on configuration...
    default: Adapter 1: nat
==> default: Forwarding ports...
    default: 22 => 2222 (adapter 1)
==> default: Booting VM...

    default: SSH address: 127.0.0.1:2222
    default: SSH username: vagrant
    default: SSH auth method: private key
    default: Warning: Connection timeout. Retrying...
    default: 
    default: Vagrant insecure key detected. Vagrant will automatically replace
    default: this with a newly generated keypair for better security.
    default: 
    default: Inserting generated public key within guest...
    default: Removing insecure key from the guest if it's present...
    default: Key inserted! Disconnecting and reconnecting using new SSH key...
==> default: Machine booted and ready!
==> default: Checking for guest additions in VM...
    default: The guest additions on this VM do not match the installed version of
    default: VirtualBox! In most cases this is fine, but in rare cases it can
    default: prevent things such as shared folders from working properly. If you see
    default: shared folder errors, please make sure the guest additions within the
    default: virtual machine match the version of VirtualBox you have installed on
    default: your host and reload your VM.
    default: 
    default: Guest Additions Version: 4.3.30
    default: VirtualBox Version: 5.0
==> default: Mounting shared folders...
    default: /vagrant => /home/katsuya/Documents/centos71vm
```

* 仮想マシンにSSH接続

```
$ vagrant ssh
[vagrant@localhost ~]$ pwd
/home/vagrant
```
