Vagrant同时管理多台机器

1. Vagrantfile

下面为1个master和3个node的配置

# 启动Node的数量
$workerNodeNumber = 3

# IP前缀
$workerNodeIpBase = "192.168.33."

# Node的IP地址数组(从192.168.33.20开始分配)
$workerNodeIps = $workerNodeNumber.times.collect {|n| $workerNodeIpBase + "#{n+20}"}

Vagrant.configure("2") do |config|

  # 定义master
  config.vm.define "master" do |master|
    master.vm.box = "centos7" # centos7为本地的box(使用`vagrant box list`查看)
    master.vm.network "private_network", ip: $workerNodeIpBase + "10" # 192.168.33.10
    master.vm.hostname = "master"
    master.vm.provider "virtualbox" do |vb|
      vb.memory = "1024" # 定义master机器的内存：1024MB
      vb.cpus = "1" # 定义master机器的CPU数量：1
      vb.name = "master" # 虚拟机名称(在VirtualBox中显示)
    end
  end

  # 定义node
  $workerNodeNumber.times do |n|
    vmName = "node#{n}"
    config.vm.define vmName do |node|
      node.vm.box = "centos7"
      node.vm.network "private_network", ip: $workerNodeIps[n]
      node.vm.hostname = "node#{n}"
      node.vm.provider "virtualbox" do |vb|
        vb.memory = "1024"
        vb.cpus = "1"
        vb.name = "node#{n}"
      end
    end
  end
end

2. 启动

vagrant up

3. 关闭

vagrant halt
