CoreOS学习之Vagrant安装
准备环境（本人电脑win7 x64）
- 1 安装最新版Oracle VM VirtualBox 4.3.18
- 2 安装最新版vagrant 1.6.5
- 3 安装windows版git
安装CoreOS
创建安装目录下载vagrant配置文件
比如我在E盘创建了一个coreos文件夹，然后在git shell界面进入这个文件夹，执行：
git clone https://github.com/coreos/coreos-vagrant.git
cd coreos-vagrant
修改git clone下来的配置文件
将config.rb.sample复制一份为config.rb
将user-data.sample复制一份为user-data
修改config.rb文件内容：
$num_instances=3 #如果安装单个coreos就写1，如果是集群就写大于1的数字
$update_channel='alpha' #这个是版本，可以改为stable或者beta
安装coreos
执行：
cd coreos-vagrant
vagrant up
此时有报错信息如下：
E:\coreos\coreos-vagrant>vagrant up
Bringing machine 'core-01' up with 'virtualbox' provider…
Bringing machine 'core-02' up with 'virtualbox' provider…
Bringing machine 'core-03' up with 'virtualbox' provider…
==> core-01: Box 'coreos-alpha' could not be found. Attempting to find and insta
ll…core-01: Box Provider: virtualbox core-01: Box Version: >= 308.0.1You specified a box version constraint with a direct box file
path. Box version constraints only work with boxes from Vagrant
Cloud or a custom box host. Please remove the version constraint
and try again.
查看Vagrantfile文件内容匹配报错有如下行：
config.vm.box_version = ">= 308.0.1"
将这一行在Vagrantfile文件里面用#注释掉，然后重新执行vagrant up：
E:\coreos\coreos-vagrant>vagrant up
Bringing machine 'core-01' up with 'virtualbox' provider…
Bringing machine 'core-02' up with 'virtualbox' provider…
Bringing machine 'core-03' up with 'virtualbox' provider…

安装完成。
配置连接
执行vagrant ssh, 会自动生成ssh的信息：
E:\coreos\coreos-vagrant>vagrant ssh core-01
sshexecutable not found in any directories in the %PATH% variable. Is an
SSH client installed? Try installing Cygwin, MinGW or Git, all of which
contain an SSH client. Or use your favorite SSH client with the following
authentication information shown below:
Host: 127.0.0.1
Port: 2222
Username: core
Private key: C:/Users/Administrator/.vagrant.d/insecure_private_key
使用xshell或者secureCRT配置私钥远程连接
