Vagrant + Virtualbox 建立 Ubuntu VM on Mac

Read Time:2 Minute, 18 Second

1. 下載並安裝Vagrant:

2. 下載並安裝VirtualBox:

3. 進終端機後找一個喜歡的路徑,在之下建立一個專案資料夾,並進到該資料夾,例:

% mkdir vagrant && cd vagrant

4. 初始化一個Ubuntu 20.04:

% vagrant init bento/ubuntu-20.04

5. Vagrant會在該目錄下建立一個Vagrantfile,目前先不用編輯它

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
`` for more information on using Vagrant.

6. 起動這個虛擬機,Vagrant會開始下載Ubuntu 20.04 的映像檔,如果中途有詢問要用哪一種VM服務,請選 Virtualbox,如果Mac已經安裝了Virtualbox,預設會使用Virtualbox:

% vagrant up


Bringing machine 'default' up with 'virtualbox' provider...
==> default: Box 'bento/ubuntu-20.04' could not be found. Attempting to find and install...
    default: Box Provider: virtualbox
    default: Box Version: >= 0

Vagrant is currently configured to create VirtualBox synced folders with
the `SharedFoldersEnableSymlinksCreate` option enabled. If the Vagrant
guest is not trusted, you may want to disable this option. For more
information on this option, please refer to the VirtualBox manual:

This option can be disabled globally with an environment variable:


or on a per folder basis within the Vagrantfile:

  config.vm.synced_folder '/host/path', '/guest/path', SharedFoldersEnableSymlinksCreate: false
==> default: Clearing any previously set network interfaces...
==> default: Preparing network interfaces based on configuration...
    default: Adapter 1: nat
==> default: Forwarding ports...
    default: 22 (guest) => 2222 (host) (adapter 1)
==> default: Booting VM...
==> default: Waiting for machine to boot. This may take a few minutes...
    default: SSH address:
    default: SSH username: vagrant
    default: SSH auth method: private key
    default: Vagrant insecure key detected. Vagrant will automatically replace
    default: this with a newly generated keypair for better security.
    default: Inserting generated public key within guest...
    default: Removing insecure key from the guest if it's present...
    default: Key inserted! Disconnecting and reconnecting using new SSH key...
==> default: Machine booted and ready!
==> default: Checking for guest additions in VM...
==> default: Mounting shared folders...
    default: /vagrant => /Users/maki/vagrant

7. 進入VM並使用sudo權限(不需密碼)

% vagrant ssh
# sudo su

就可以開始用Ubuntu VM了
