使用vagrant创建多台虚拟机

• 安装virtualbox
• 安装vagrant2.2.3
• vagrant init
• 修改agrantfile

VAGRANTFILE_API_VERSION = "2"
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
   (1..5).each do |i|
       config.vm.define "node#{i}" do |node|
           node.vm.box = "../iso/CentOS-7-x86_64-Vagrant-1811_02.VirtualBox.box"
           #node.vm.box = "Centos/7"
           node.vm.hostname = "node#{i}"
           node.vm.network "public_network"
           node.vm.provider "virtualbox" do |v|
               v.name = "node#{i}"
               v.memory = 4096
               v.cpus = 2
           end
       end
   end
end
