首先介绍一下vagrant,Vagrant是一个基于Ruby的工具，用于创建和部署虚拟化开发环境。它使用Oracle的开源VirtualBox虚拟化系统，使用 Chef创建自动化虚拟环境。 而Oracle最近推出了Oracle 18c数据库，现在可以在带有Vagrant的GitHub存储库中使用。在几分钟内，我们可以为这个要求准备好具有DB的VM，用于沙盒测试和QA环境。那么接下来我们来实际安装一下。
前提条件
1.安装Oracle VirtualBox
2.安装Vagrant
3.下载Oracle 18c安装介质
4.下载来自GitHub的Vagrant配置文件
在成功安装VirtualBox和Vagrant之后，我们需要下载或者是克隆GitHub上的配置文件，这里我使用的是windows上安装的Git Bash。运行命令：git clone https://github.com/oracle/vagrant-boxes。运行成功后会自动把配置文件下载下来，并存放在Git Bash软件的根目录下。
接下来我们把配置文件拷贝到一个单独的文件夹下面，同时我们需要把Oracle 18c的安装介质存放到vagrant-boxes\OracleDatabase\18.3.0这个目录下，如图所示：
上述操作完成之后，我们先来测试一下我们的Vagrant命令是否可以使用。
PS C:\Users\Administrator> vagrant -h Usage: vagrant [options][] -v, --version Print the version and exit. -h, --help Print this help. Common commands: box manages boxes: installation, removal, etc. destroy stops and deletes all traces of the vagrant machine global-status outputs status Vagrant environments for this user halt stops the vagrant machine help shows the help for a subcommand init initializes a new Vagrant environment by creating a Vagrantfile login log in to HashiCorp's Vagrant Cloud package packages a running vagrant environment into a box plugin manages plugins: install, uninstall, update, etc. port displays information about guest port mappings powershell connects to machine via powershell remoting provision provisions the vagrant machine push deploys code in this environment to a configured destination rdp connects to machine via RDP reload restarts vagrant machine, loads new Vagrantfile configuration resume resume a suspended vagrant machine snapshot manages snapshots: saving, restoring, etc. ssh connects to machine via SSH ssh-config outputs OpenSSH valid configuration to connect to the machine status outputs status of the vagrant machine suspend suspends the machine up starts and provisions the vagrant environment validate validates the Vagrantfile version prints current and latest Vagrant version For help on any individual command run `vagrant COMMAND -h` Additional subcommands are available, but are either more advanced or not commonly used. To see all subcommands, run the command `vagrant list-commands`.
接下来我们要到刚刚配置好的G:\VM DATA\vagrant-boxes\OracleDatabase\18.3.0目录去运行vagrant up。也就是上面的starts and provisions the vagrant environment。不过我在运行这个命令的时候出了一点小问题，默认vagrant是依赖Windows的powershell的。然后报错提示powershell的版本是2，需要版本为3。然后我check了一下，的确我的版本是2。然后在百度上搜索了一下，首先需要安装.NET 4.0或者.NET 4.5。然后在安装Microsoft Windows Management Framework 3.0的6.1内核版本安装文件，链接在这里。默认我已经安装了.NET 4.0框架，我没有安装3.0的6.1内核版本安装文件。我把链接的补丁下载下来安装好了之后再次check版本就变成3了。
The version of powershell currently installed on this host is less than the required minimum version. Please upgrade the installed version of powershell to the minimum required version and run the command again. PS C:\Users\Administrator> get-host Name : ConsoleHost Version : 2.0 InstanceId : 2dae0b07-3120-4576-b81b-fa329f22a38f UI : System.Management.Automation.Internal.Host.InternalHostUserInterface CurrentCulture : zh-CN CurrentUICulture : zh-CN PrivateData : Microsoft.PowerShell.ConsoleHost+ConsoleColorProxy IsRunspacePushed : False Runspace : System.Management.Automation.Runspaces.LocalRunspace
安装了3.0的6.1内核版本安装文件之后，再次check。
PS C:\Users\Administrator> get-host Name : ConsoleHost Version : 3.0 InstanceId : d1c831a7-e985-403f-88cd-c338b212864a UI : System.Management.Automation.Internal.Host.InternalHostUserInterface CurrentCulture : zh-CN CurrentUICulture : zh-CN PrivateData : Microsoft.PowerShell.ConsoleHost+ConsoleColorProxy IsRunspacePushed : False Runspace : System.Management.Automation.Runspaces.LocalRunspace
然后再次运行vagrant up,这次一切顺利。然后就开始构建环境了。最后安装完成之后会提示：INSTALLER: Installation complete, database ready to use.
现在，我们可以检查Vagrant是否已启动。
