Frances Du's questions

下面是我的流浪文件。但是，它没有创建 1 个 RedHat 虚拟机和 2 个 Ubuntu 虚拟机，而是“流浪”了 3 个 Ubuntu 虚拟机。

有人可以告诉我为什么吗？先感谢您！

Vagrant.configure("2") do |config|
  config.ssh.insert_key = false
  config.vm.synced_folder ".", "/vagrant", disabled: true
  config.vm.provider :virtualbox do |v|
    v.memory = 4000
    v.linked_clone = false
  end

# App server 1   
config.vm.box = "geerlingguy/centos7"
  config.vm.define "app1" do |app|
    app.vm.hostname = "orc-app1.test"
    app.vm.network :private_network, ip: "192.168.60.4"
  end

# App server 2   
config.vm.box = "geerlingguy/ubuntu2004"
  config.vm.define "app2" do |app|
   app.vm.hostname = "orc-app2.test"
    app.vm.network :private_network, ip: "192.168.60.5"
  end

# DB server   
config.vm.box = "geerlingguy/ubuntu2004"
  config.vm.define "db" do |db|
    db.vm.hostname = "orc-db.test"
    db.vm.network :private_network, ip: "192.168.60.6"
  end
end
