1.下载安装 VirtualBox 和 Vagrant：

Vagrant 下载：
https://www.vagrantup.com/

VirtualBox 下载：
https://www.virtualbox.org/wiki/Downloads

2.使用 Vagrant 安装 Centos

C:\Users\keegan>vagrant -v
Vagrant 2.2.19

C:\Users\keegan>cd Desktop
C:\Users\keegan\Desktop>mkdir test
C:\Users\keegan\Desktop>cd test

C:\Users\keegan\Desktop\test>vagrant init centos/7
A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
`vagrantup.com` for more information on using Vagrant.
###======》或者 vagrant init centos7 https://mirrors.ustc.edu.cn/centos-cloud/centos/7/vagrant/x86_64/images/CentOS-7.box

C:\Users\keegan\Desktop\test>vagrant up   ###======》 重新加载镜像

###======>很慢，手动下载复制到test目录下
###下载地址：https://cloud.centos.org/centos/7/vagrant/x86_64/images/CentOS-7-x86_64-Vagrant-2004_01.VirtualBox.box

然后
进入盘路径符，cmd----回车
vagrant box add centos/7 CentOS-7-x86_64-Vagrant-2004_01.VirtualBox.box
或者进入
C:\Users\keegan\Desktop>cd test
C:\Users\keegan\Desktop\test> vagrant box add centos/7 CentOS-7-x86_64-Vagrant-2004_01.VirtualBox.box

3.怎么进入虚拟机里面玩它？

就会来到cmd:

输入：

C:\Users\keegan\Desktop\test>vagrant ssh

安装git:

[vagrant@localhost ~]$ ls -al
[vagrant@localhost ~]$ pwd
[vagrant@localhost ~]$ ping www.baidu.com
[vagrant@localhost ~]$ sudo yum install git

如果我想退出虚拟环境，那么敲 exit:

可以看到 default running (virtualbox) default 正在运行：

关于虚拟机的关机和启动：

C:\Users\keegan\Desktop\test>vagrant halt
C:\Users\keegan\Desktop\test>vagrant up

删除该虚拟机：

C:\Users\keegan\Desktop\test>vagrant ssh
Last login: Wed Jan 26 15:39:29 2022 from 10.0.2.2
[vagrant@localhost ~]$ exit
logout
Connection to 127.0.0.1 closed.

C:\Users\keegan\Desktop\test>vagrant halt
==> default: Attempting graceful shutdown of VM...

C:\Users\keegan\Desktop\test>vagrant destroy
    default: Are you sure you want to destroy the 'default' VM? [y/N] N

安装go环境：

mkdir ~/go && cd ~/go
sudo yum -y install wget
wget https://studygolang.com/dl/golang/go1.16.linux-amd64.tar.gz
sudo tar -C /usr/local -zxvf go1.16.linux-amd64.tar.gz
rpm -qa|grep vim
sudo yum -y install vim*

sudo vim /etc/profile
# 在最后一行添加
export GOROOT=/usr/local/go
export PATH=$PATH:$GOROOT/bin
source /etc/profile
# 开启go module
go env -w GO111MODULE=on
go env -w GOPROXY=https://goproxy.cn,direct

远程开发：
config.ssh.username = “vagrant”
config.ssh.password = “vagrant”
修改密码配置

设置外部网络访问虚拟机—宿主机自己电脑ping不同虚拟机，但虚拟机可以ping通宿主机：

设置静态ip地址，编辑网络配置文件，选择之前设置的网络设置文件：

TYPE="Ethernet"
PROXY_METHOD="none"
BROWSER_ONLY="no"
BOOTPROTO="static"          # static静态IP地址，dhcp动态IP地址
ONBOOT="yes"                # 将ONBOOT="no"改为ONBOOT="yes"，开启网卡自动连接
DEFROUTE="yes"
IPV4_FAILURE_FATAL="no"
IPV6INIT="yes"
IPV6_AUTOCONF="yes"
IPV6_DEFROUTE="yes"
IPV6_FAILURE_FATAL="no"
IPV6_ADDR_GEN_MODE="stable-privacy"
NAME="eth0"
DEVICE="eth0"
IPADDR="192.168.8.100"         # ip地址
NETMASK="255.255.255.0"        # 子网掩码
GATEWAY="192.168.8.1"          # 网关
DNS1="8.8.8.8"                 # 修改DNS服务器

virtualbox复制粘贴设置：

就配置好了。

以上就是Vagrant+VirtualBox 的基操了，其他的就是linux的常用操作了。
