前言
好久没用homestead环境了，一启动遇到如下问题
Bringing machine 'homestead-7' up with 'virtualbox' provider...
==> homestead-7: Importing base box 'laravel/homestead'...
==> homestead-7: Matching MAC address for NAT networking...
==> homestead-7: Checking if box 'laravel/homestead' is up to date...
==> homestead-7: Setting the name of the VM: homestead-7
==> homestead-7: Clearing any previously set network interfaces...
==> homestead-7: Preparing network interfaces based on configuration...
homestead-7: Adapter 1: nat
homestead-7: Adapter 2: hostonly

homestead-7: 80 (guest) => 8000 (host) (adapter 1)
homestead-7: 443 (guest) => 44300 (host) (adapter 1)
homestead-7: 3306 (guest) => 33060 (host) (adapter 1)
homestead-7: 5432 (guest) => 54320 (host) (adapter 1)
homestead-7: 22 (guest) => 2222 (host) (adapter 1)
==> homestead-7: Running 'pre-boot' VM customizations...
==> homestead-7: Booting VM...
==> homestead-7: Waiting for machine to boot. This may take a few minutes...
homestead-7: SSH address: 127.0.0.1:2222
homestead-7: SSH username: vagrant
homestead-7: SSH auth method: private key
Timed out while waiting for the machine to boot. This means that
Vagrant was unable to communicate with the guest machine within
the configured ("config.vm.boot_timeout" value) time period.
If you look above, you should be able to see the error(s) that
Vagrant had when attempting to connect to the machine. These errors
are usually good hints as to what may be wrong.
If you're using a custom box, make sure that networking is properly
working and you're able to connect to the machine. It is a common
problem that networking isn't setup properly in these boxes.
Verify that authentication configurations are also setup properly,
as well.
If the box appears to be booting properly, you may want to increase
the timeout ("config.vm.boot_timeout") value.
问题分析
明显的是超时
回想我中间做了啥，对 了，是从新生成了ssh-key！！！！！
但是，我删除了~/.vagrant/下面的private key 就是我自己电脑的~/.ssh下面的！！！！
中间还尝试过重新更新virtualbox的镜像！
包括，virtualbox中设置总要点击选中 『网络』接入网线，这个选项！！！
无济于事！！！
最后，无意运行了一行命令，打开了思路
vagrant status 如下

问题来了，我启动 VM的名字是homestead-7，为何这里的status显示的是default，而这个default 确实是没有打开的啊！！！！
问题应该就是在这里了，就是我homestead up 启动但是 homestead-7虚拟机，而homestead ssh连接的时候呢，却默认连接的是 名字为default的VM所以，连接不上也很正常啊！！！！！
解决
- 删除~/.vagrant文件
- homestead halt，停止正在运行的虚拟机
- 重新homestead up 启动
注意
- 如果你留意你会发现，homestead-7和default这两个虚拟机啥关系呢？这里的关系是，你使用homestead命令启动就是，否则就是default，defalut的端口映射默认很少
- 开发laravel的时候，一定要用homestead这个命令，方面的地方在于，无论你在哪个地方，都会定位到同一个文件夹执行homestead。这样，得到的环境才一样！
我的理解，你再某一个文件夹下面操作vagrant 配置会和这个文件夹有些关系。
不对多多指教！！！！
