一、 專案架構
二、使用vagrant建立虛擬機器
2.1 安裝Centos7
$ 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.
執行完上面的命令後，會在使用者的家目錄下生成Vagrantfile檔案。
$ vagrant up Bringing machine 'default' up with 'virtualbox' provider... ==> default: Box 'centos/7' could not be found. Attempting to find and install... default: Box Provider: virtualbox default: Box Version: >= 0 ==> default: Loading metadata for box 'centos/7' default: URL: https://vagrantcloud.com/centos/7 ==> default: Adding box 'centos/7' (v1905.1) for provider: virtualbox default: Downloading: https://vagrantcloud.com/centos/boxes/7/versions/1905.1/providers/virtualbox.box default: Download redirected to host: cloud.centos.org default: Progress: 0% (Rate: 6717/s, Estimated time remaining: 7:33:42)
下載映象過程比較漫長，也可以採用先用下載工具下載到本地後，然後使用“ vagrant box add ”新增，再“vagrant up”即可
#將下載的映象新增到virtualBox中 $ vagrant box add centos/7 E:\迅雷下載\CentOS-7-x86_64-Vagrant-1905_01.VirtualBox.box ==> box: Box file was not detected as metadata. Adding it directly... ==> box: Adding box 'centos/7' (v0) for provider: box: Unpacking necessary files from: file:///E:/%D1%B8%C0%D7%CF%C2%D4%D8/CentOS-7-x86_64-Vagrant-1905_01.VirtualBox.box box: ==> box: Successfully added box 'centos/7' (v0) for 'virtualbox'! #啟動 $ vagrant up Bringing machine 'default' up with 'virtualbox' provider... ==> default: Importing base box 'centos/7'... ==> default: Matching MAC address for NAT networking... ==> default: Setting the name of the VM: Administrator_default_1588497928070_24634 ==> default: Clearing any previously set network interfaces... ==> default: Preparing network interfaces based on configuration... default: Adapter 1: nat default: Adapter 2: hostonly ==> 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: 127.0.0.1:2222 default: SSH username: vagrant default: SSH auth method: private key default: default: Vagrant insecure key detected. Vagrant will automatically replace default: this with a newly generated keypair for better security. default: 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: No guest additions were detected on the base box for this VM! Guest default: additions are required for forwarded ports, shared folders, host only default: networking, and more. If SSH fails on this machine, please install default: the guest additions and repackage the box to continue. default: default: This is not an error message; everything may continue to work properly, default: in which case you may ignore this message. ==> default: Configuring and enabling network interfaces... ==> default: Rsyncing folder: /cygdrive/c/Users/Administrator/ => /vagrant
vagrant ssh 開啟SSH，並登陸到centos7
