  • 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:

  • 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

  • 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

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。
