官方下载和添加 Box

添加box指令：vagrant box add [自定义名称] [box镜像路径]
官方box镜像地址： https://app.vagrantup.com/boxes/search?order=desc&page=1&sort=downloads

下载添加Box演示

移除box指令：vagrant box remove box名称

手动下载Box并添加

为什么要手动下载？某些时候网络很慢又急需的时候
这里提供一个centos7的镜像百度网盘分享，分享码：70tj
下图为本地Box添加演示（由于我并未下载该文件故有 could not be found 错误提示）

添加本地Box演示

初始化配置与Box使用

首先强烈建议修改虚拟机镜像安装地址（因为window上、他默认放在C盘。当然后期再改也没问题，如果你不嫌麻烦的话）
为什么要改这个地址？请看下图
centos7镜像基本信息
VirtualBox虚拟机
还需要安装一个vagrant插件。看下图：
vagrant插件安装演示
使用 vagrant init [box-name] 生成 Vagrantfile 文件(box-name为box名称、默认为base)
使用 vagrant up启动一般在Vagrantfile 文件同级生成.vagrant的配置文件夹（如果是首次启动通常比较慢，会生成虚拟机镜像，镜像位置以我们上一步配置的路径地址为准）
初始化与启动演示
Vagrantfile文件常用设置如下：

Vagrant.configure("2") do |config|
  config.vm.box = "centos/7" # 使用的Box名称
  config.vm.hostname = "centos7" # 自定义的名称
  # 登录用户名（默认有vagrant这个用户、在未设置之前root可能登录不了）
  config.ssh.username = 'vagrant' 
  config.ssh.password = "vagrant" # 默认的登录密码 （root用户的默认密码也是这个密码）
  # 是否使用秘钥、公钥登录（默认为true,如果设为true那么上面的账号密码是无效的，建议设为true）
  config.ssh.insert_key = false 
  # 以下是需要映射的端口 guest：虚拟机端口 host：本机端口
  config.vm.network "forwarded_port", guest: 80, host: 80
  config.vm.network "forwarded_port", guest: 443, host: 443
  config.vm.network "forwarded_port", guest: 3306, host: 3306
  # 为虚拟机分配内网IP地址。 SSH可以直接通过192.168.1.10连接
  config.vm.network "public_network", ip:"192.168.1.10"
  # 需要共享的目录（即我们可在本机修改"D:/WWW"的文件，而在虚拟机环境中运行"/wwwroot"的代码）
  config.vm.synced_folder "D:/WWW", "/wwwroot"

修改配置文件需要重启。指令：vagrant reload。启动成功后可通过快捷指令连接：vagrant reload
注：如果在重启或者启动过程中提示尝试登录失败一般为公钥秘钥对应不上。可通过类似这样的ssh vagrant@192.168.1.10ssh命令直接登录使用密码登录即可。所有账号默认密码均为：vagrant

实现root账号的免密登录

查看本机是否已生成公钥、秘钥。如果没有则按下图第4个命令生成（如果没有特别需要可一路回车即可）
演示
查看虚拟机是否有该文件（如果没有则创建）
authorized_keys
将本机的公钥id_rsa.pub内容复制到虚拟机的authorized_keys中（如果需要多台免密登录authorized_keys里的公钥是可以叠加的）
设置权限

# 设置.ssh目录权限
$ chmod 700 -R .ssh
# 设置authorized_keys权限
$ chmod 600 authorized_keys

允许root用户远程登录设置

# 虚拟机编辑ssh配置文件（编辑后需要重启sshd服务，命令：```systemctl reload sshd``` 或 ```service sshd reload```）
 vi /etc/ssh/ssh_config

通常的配置：

# 允许使用密码登录
PasswordAuthentication yes
# 允许root认证登录
PermitRootLogin yes
# 允许密钥认证
RSAAuthentication yes
PubkeyAuthentication yes
# 默认公钥存放的位置
AuthorizedKeysFile  .ssh/authorized_keys

如果找不到以上某些配置项也不要慌。其实你已经开启了，具体参考CentOS7.4踩坑查看版本命令：cat /etc/redhat-release
这个时候本机就可以通过ssh命令远程登录。如果不行请通过cat ~/.ssh/authorized_keys再次确认你的公钥修改已经正确！

关于 `vagrant ssh`无法免密登录问题

查看Vagrantfile文件配置项config.ssh.insert_key是否为true
通过如下指令查看IdentityFile指向的文件是否存在，并且文件内容是否为存贮在虚拟机中authorized_keys文件中的公钥对应的私钥

# vagrant 指令
vagrant ssh-config
  # 响应内容如下
  Host default
  HostName 127.0.0.1
  User root
  Port 2222
  UserKnownHostsFile /dev/null
  StrictHostKeyChecking no
  PasswordAuthentication no
  # 检查该键指向的文件
  IdentityFile E:/Vagrant/centos7/.vagrant/machines/default/virtualbox/private_key
  IdentitiesOnly yes
  LogLevel FATAL

关于vagrant镜像无法访问问题（将异常的配置文件后缀`.temp`去掉即可）

发生的原因：通常为vagrant启动过程被冲断产生
正常的vagrant关机状态和镜像文件如下：

# vagrant 指令
vagrant status
# 响应数据
Current machine states:
default                   poweroff (virtualbox)
The VM is powered off. To restart the VM, simply run `vagrant up`

正常镜像

无法访问状态和镜像文件如下：

# vagrant 指令
vagrant status
# 响应数据
Current machine states:
default                   inaccessible (virtualbox)

无法访问状态镜像

关联已存在的镜像问题

发生原因：当我们删除.vagrant文件夹之后产生
如下空镜像状态信息（注：首次启动即为该状态）：

# vagrant 指令
vagrant status
# 响应数据
Current machine states:
default                   not created (virtualbox)
The environment has not yet been created. Run `vagrant up` to
create the environment. If a machine is not created, only the
default provider will be shown. So if a provider is not listed,
then the machine is not created for that environment.

如果该状态是异常的其实你已经有了镜像只是他无法关联那么解决方法如下：
1. 通过vagrant up生成以下文件。立刻通过进程管理器关闭````ruby.exe```（大概）这个名的进程（注：如果不关闭，那么他将重新生成一个新的镜像）
  .vagrant目录下所需的文件
2. 我们打开如下文件的值替换掉上图中的id文件的内容。此时通过vagrant status指令即可查看到正常的状态提示
  uuid值
