Mac下vagrant从安装到体验
Mac下使用虚拟机时，通过vagrant+virtualbox的组合是个不错的方案，简便快捷；
安装步骤
- virtualbox官网下载，地址：https://www.virtualbox.org/wiki/Downloads ，如下，下载完毕后双击安装：

- vagrant官网下载，地址：https://www.vagrantup.com/downloads.html ，如下，下载完毕后双击安装：

- 安装完成后在命令行执行命令vagrant -v，查看版本号如下：
(base) zhaoqindeMBP:~ zhaoqin$ vagrant -v
Vagrant 2.2.5安装完毕，接下来开始体验；
体验
注意：体验之前请再三确认virtualbox已经安装成功，最好是双击图标启动virtualbox，确认能够启动成功；
- 检查已有的虚拟机列表vagrant box list，提示还没有任何虚拟机：
(base) zhaoqindeMBP:~ zhaoqin$ vagrant box list
There are no installed boxes! Use `vagrant box add` to add some.- 去虚拟机镜像仓库找个合适的镜像，地址是：https://app.vagrantup.com/boxes/search ，如下图，咱们用centos来完成初次体验吧，点击红框位置：

- 在新页面中，点击下图红框中的"New"按钮，即可看到使用该虚拟机的命令：

- 按照上图的提示，在命令行执行vagrant init centos/7，即可在当前目录生成此虚拟机的配置文件Vagrantfile：
base) zhaoqindeMBP:18 zhaoqin$ 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.- 打开Vagrantfile看看，如下图，只有少量信息，看来主要用的都是默认配置：

- 执行命令启动虚拟机，接下来需要等待10分钟左右，控制台输出以下信息表示启动虚拟机成功：
(base) zhaoqindeMBP:18 zhaoqin$ vagrant up

==> default: Rsyncing folder: /Users/zhaoqin/temp/201908/18/ => /vagrant- ssh登录：
vagrant ssh- 登录成功后，查看虚拟机操作系统版本，可见是centos7.6：
[vagrant@localhost ~]$ cat /etc/redhat-release
CentOS Linux release 7.6.1810 (Core)- 退出ssh，回到控制台：
exit基本命令
- 关闭虚拟机：
vagrant halt- 启动虚拟机：
vagrant up- 重启虚拟机：
vagrant reload- 删除虚拟机：
vagrant destroy修改配置
- 接下来尝试修改虚拟机的配置文件Vagrantfile，在Vagrantfile中添加如下图红框中的内容，作用是将虚拟机内存设置为2G：

- 执行vagrant reload重启虚拟机，然后执行vagrant ssh进入虚拟机，执行free -m查看内存情况，可见设置已经生效：
(base) zhaoqindeMBP:18 zhaoqin$ vagrant ssh
Last login: Sun Aug 18 08:09:43 2019 from 10.0.2.2
[vagrant@localhost ~]$ free -m
total used free shared buff/cache available
Mem: 1838 70 1655 8 112 1624
Swap: 2047 0 2047至此，Mac下的vagrant安装和体验就完成了，希望本文能给您一些参考，帮助您快速搭建虚拟机环境。
