vagrant 使用說明
查看版本號(hào)
vagrant -v
Vagrant 2.2.6
安裝完畢，接下來開始體驗(yàn)顶滩；
體驗(yàn)
注意：體驗(yàn)之前請(qǐng)?jiān)偃_認(rèn)virtualbox已經(jīng)安裝成功寸爆，最好是雙擊圖標(biāo)啟動(dòng)virtualbox而昨，確認(rèn)能夠啟動(dòng)成功；
vagrant box list
There are no installed boxes! Use `vagrant box add` to add some.
檢查已有的虛擬機(jī)列表vagrant box list，提示還沒有任何虛擬機(jī)：
查找鏡像
去虛擬機(jī)鏡像倉庫找個(gè)合適的鏡像务嫡，地址是：https://app.vagrantup.com/boxes/search 漆改，如下圖，咱們用centos來完成初次體驗(yàn)吧去扣，點(diǎn)擊紅框位置：
在新頁面中愉棱，點(diǎn)擊下圖紅框中的"New"按鈕哲戚，即可看到使用該虛擬機(jī)的命令：
vagrant init
按照上圖的提示顺少，在命令行執(zhí)行vagrant init centos/7王浴，即可在當(dāng)前目錄生成此虛擬機(jī)的配置文件Vagrantfile：
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.
打開Vagrantfile看看氓辣，如下圖袱蚓，只有少量信息，看來主要用的都是默認(rèn)配置：
啟動(dòng)
執(zhí)行命令啟動(dòng)虛擬機(jī)，接下來需要等待10分鐘左右响蓉，控制臺(tái)輸出以下信息表示啟動(dòng)虛擬機(jī)成功

ssh登錄：
vagrant ssh
登錄成功后，查看虛擬機(jī)操作系統(tǒng)版本粱栖，可見是centos7.6：
[vagrant@localhost ~]$ cat /etc/redhat-release
CentOS Linux release 7.7.1908 (Core)
退出ssh脏毯，回到控制臺(tái)：
exit
基本命令
- 關(guān)閉虛擬機(jī)：
vagrant halt
- 啟動(dòng)虛擬機(jī)：
vagrant up
- 重啟虛擬機(jī)：
vagrant reload
- 刪除虛擬機(jī)：
vagrant destroy
修改配置
接下來嘗試修改虛擬機(jī)的配置文件Vagrantfile食店，在Vagrantfile中添加如下圖紅框中的內(nèi)容，作用是將虛擬機(jī)內(nèi)存設(shè)置為2G：
執(zhí)行vagrant reload重啟虛擬機(jī)价认，然后執(zhí)行vagrant ssh進(jìn)入虛擬機(jī)自娩，執(zhí)行free -m查看內(nèi)存情況，可見設(shè)置已經(jīng)生效：

至此脐彩，Mac下的vagrant安裝和體驗(yàn)就完成了丁屎，希望本文能給您一些參考旱眯，幫助您快速搭建虛擬機(jī)環(huán)境证九。
