## 其中一个有效可行方案

```ruby

# -*- mode: ruby -*-
# vi: set ft=ruby :

servers = {
    :ct1 => "192.168.30.30",
    :ct2 => "192.168.30.31",
    :ct3 => "192.168.30.32"
}

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

config.vm.box = "centos6-mini-nfs"
  config.vm.box_check_update = false

servers.each do |server_name, server_ip|
      config.vm.define server_name do |server_config|

server_config.vm.hostname = "#{server_name.to_s}"
          server_config.vm.network :private_network, ip: server_ip

server_config.vm.provider "virtualbox" do |vb|
              vb.name = server_name.to_s
                        vb.memory = "256"
                        vb.cpus = 1
         end
      end
  end
end
```

## 另外一个可行方案

```ruby

Vagrant.configure("2") do |config|
   (1..3).each do |i|
        config.vm.define "node#{i}" do |node|
            # 设置虚拟机的Box
            node.vm.box = "centos6-mini-nfs"

# 设置虚拟机的主机名
            node.vm.hostname="node#{i}"

# 设置虚拟机的IP
            node.vm.network "private_network", ip: "192.168.30.#{40+i}"

# 设置主机与虚拟机的共享目录
            # node.vm.synced_folder "~/Documents/vagrant/share", "/home/vagrant/share"

# VirtaulBox相关配置
            node.vm.provider "virtualbox" do |v|
                # 设置虚拟机的名称
                v.name = "s-#{i}"
                # 设置虚拟机的内存大小
                v.memory = 256
                # 设置虚拟机的CPU个数
                v.cpus = 1
            end
        end
   end
end
