使用
Vagrant
+VirtualBox
在 Windows 上快速创建三台能ping
通局域网及公网的安装好docker
的centos7
虚拟机
下载并且安装软件

https://www.vagrantup.com/downloads
https://app.vagrantup.com/centos/boxes/7
添加虚拟机
# 下载 box 文件添加到虚拟机中,执行如下命令
$ vagrant box add centos7 CentOS-7-x86_64.box
新建配置文件

执行 vagrant up
命令,按照配置 Vagrantfile
文件遍历创建虚拟机,并执行 shell
脚本去初始化虚拟机
Vagrant 常用命令
命令 | 作用 |
---|---|
vagrant box add | 添加box的操作 |
vagrant init | 初始化box的操作,会生成vagrant的配置文件Vagrantfile |
vagrant up | 启动本地环境 |
vagrant ssh | 通过ssh登录本地环境所在虚拟机 |
vagrant halt | 关闭本地环境 |
vagrant suspend | 暂停本地环境 |
vagrant resume | 恢复本地环境 |
vagrant reload | 修改了Vagrantfile后,使之生效(相当于先halt,再up) |
vagrant destroy | 彻底移除本地环境 |
vagrant box list | 显示当前已经添加的box列表 |
vagrant box remove | 删除相应的box |
vagrant package | 打包命令,可以把当前的运行的虚拟机环境进行打包 |
vagrant plugin | 用于安装卸载插件 |
vagrant status | 获取当前虚拟机的状态 |
vagrant global-status | 显示当前用户Vagrant的所有环境状态 |
