1. Install golang

    tar -C /usr/local -xzf go1.7.3.linux-amd64.tar.gz
/etc/profile
export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin
export PATH=$PATH:/usr/local/go/bin
source /etc/profile

  2. Install GCC/OpenSSL

    yum install -y openssl-devel
yum groupinstall -y "Development Tools"

  3. Install goget

    安装goget工具
go get github.com/coderhaoxin/goget
cp goget /usr/local/bin/

  4. Install VirtualBox

    VirtualBox安装
cd  /etc/yum.repos.d/
goget http://download.virtualbox.org/virtualbox/rpm/el/virtualbox.repo
yum install -y VirtualBox-5.1

  5. VirtualBox安装 https://www.virtualbox.org/wiki/Linux_Downloads

  6. Vagrant安装 https://www.vagrantup.com/downloads.html

  7. 下载Centos Linux Box(http://www.vagrantbox.es/)

    goget https://releases.hashicorp.com/vagrant/1.8.6/vagrant_1.8.6_x86_64.rpm
cd /root/.vagrant.d/boxes
goget https://github.com/CommanderK5/packer-centos-template/releases/download/0.7.2/vagrant-centos-7.2.box
goget https://github.com/kraksoft/vagrant-box-ubuntu/releases/download/14.04/ubuntu-14.04-amd64.box
cd /root/.vagrant.d/boxes
vagrant box add cent1 /root/.vagrant.d/boxes/vagrant-centos-7.2.box
vagrant box add cent2 /root/.vagrant.d/boxes/vagrant-centos-7.2.box
vagrant box add cent3 /root/.vagrant.d/boxes/vagrant-centos-7.2.box
vagrant init cent1
vagrant up
注：
vagrant reload 修改配置后重启
vagrant up

  8. Vagrantfile配置参考

    Vagrant.configure("2") do |config|
  config.vm.define :cent1 do |cent1|
    cent1.vm.provider "virtualbox" do |v|
          v.customize ["modifyvm", :id, "--name", "cent1", "--memory", "512"]
    end
    cent1.vm.box = "cent1"
    cent1.vm.hostname = "cent1"
    cent1.vm.network :private_network, ip: "192.168.2.110"
  end
    
  config.vm.define :cent2 do |cent2|
    cent2.vm.provider "virtualbox" do |v|
          v.customize ["modifyvm", :id, "--name", "cent2", "--memory", "512"]
    end
    cent2.vm.box = "cent2"
    cent2.vm.hostname = "cent2"
    cent2.vm.network :private_network, ip: "192.168.2.120"
  end
      
  config.vm.define :cent3 do |cent3|
    cent3.vm.provider "virtualbox" do |v|
          v.customize ["modifyvm", :id, "--name", "cent3", "--memory", "512"]
    end
    cent3.vm.box = "cent2"
    cent3.vm.hostname = "cent3"
    cent3.vm.network :private_network, ip: "192.168.2.130"
  end
end

  9. 使用（注意执行下面的命令 一定要在Vagrantfile 同目录下进行）

    vagrant ssh cent1
vagrant ssh cent2
vagrant ssh cent3

    分别登录三个服务器

    vagrant global-status

    ip 命令 替代老的ifconfig

    https://linuxstory.org/replacing-ifconfig-with-ip/

    ip -4 a 注：虚拟器的 /vagrant目录 映射的就是 主机目录/root/install/

  11. 使用libvirt配置多节点的Vagrant集群
