基础-01项目环境（虚拟机、docker、idea）
一、 项目架构
二、使用vagrant创建虚拟机
下载VirtualBox（开源虚拟机软件）
下载Vagrant（官网下载地址好像只能在fq后下载）
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。
BBC Vagrant 是基于VirtualBox创建的虚拟机，并通过Vagrant进行打包而得到的VM环境。在虚拟机中部署好开发环境并建立虚拟机和实体机的文件共享，在开发时，可以通过实体机进行文件修改，并经过虚拟机中的环境执行，从而实现不同操作系统的工作环境的轻松部署。
-
下载box文件。
-
执行vagrant init 。（会自动下载文件） ---- 也可以自己下载镜像然后添加
vagrant init centos/7 -
执行vagrant up。
vagrant up
vagrant常用命令
| vagrant box list | 查看目前已有的box |
|---|---|
| vagrant box add [BOX NAME] [BOX URL] | 新增加一个box |
| vagrant box remove [BOX NAME] | 删除指定box |
| vagrant init [BOX NAME] | 初始化配置vagrantfile |
| vagrant up | 启动虚拟机 |
| vagrant ssh | ssh登录虚拟机 |
| vagrant suspend | 挂起虚拟机 |
| vagrant reload | 重启虚拟机 |
| vagrant halt | 关闭虚拟机 |
| vagrant status | 查看虚拟机状态 |
| vagrant destroy | 删除虚拟机 |
- 所有操作需要在workspace目录下执行
- 浏览页面是127.0.0.1:8000。对应workspace/ecstore/
- mysql网页配置端口是3306，如果需要从母机连接，需要访问33060端口。
- 如果需要连接ssh，为：vagrant ssh 即可。
- windows下，因为virtualbox本身一个bug，所以不能使用4.3.18版本，4.3.12版本可以用。
- win8可能需要改bios（开启intel的虚拟技术intel Virtualization Technology）
- box中的系统是64位的，建议在64位操作系统中使用
2.1 安装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.
执行完上面的命令后，会在用户的家目录下生成Vagrantfile文件。
$ vagrant up

==> default: Box 'centos/7' could not be found. Attempting to find and install...
default: Box Provider: virtualbox
default: Box Version: >= 0

下载镜像过程比较漫长，也可以采用先用下载工具下载到本地后，然后使用“ vagrant box add ”添加，再“vagrant up”即可
#将下载的镜像添加到virtualBox中
$ vagrant box add centos/7 E:\迅雷下载\CentOS-7-x86_64-Vagrant-1905_01.VirtualBox.box
