本想使用 Laravel Valet，但本机上有较低版本的PHP，决定采用全平台支持的Homestead。
Laravel 致力于让整个 PHP 开发过程变得让人愉悦，包括本地开发环境，官方为我们提供了一整套本地开发环境 —— Laravel Homestead。
安装：
需要先安装Vagrant和VirtualBox，安装完之后，在ITerm中使用如下命令将 laravel/homesterad 添加到 Vagrant 中。
vagrant box add laravel/homestead
结果就尴尬了，下载到4%就断了，尝试了几次换迅雷离线下载，成功下载了
https://atlas.hashicorp.com/laravel/boxes/homestead/versions/2.1.0/providers/virtualbox.box
再次添加：vagrant box add laravel/homestead ./virtualbox.box
安装 Homestead
|
|
再在Homestead目录中执行init
cd Homestead
bash init.sh当前目录下的Homestead.yaml基本不用修改，需要注意的是sites段路径是否符合项目
sites:
- map: homestead.app
to: /home/vagrant/Code/Laravel/public
启动 Vagrant Box：vagrant up
并没有想像的那么顺利，提示找不到ssh key；生成
ssh-keygen -t rsa -C "austgl@qq.com"再次执行vagrant up，发现还是会从外网下载，用list看了下盒子已经存在了的
vagrant box list
laravel/homestead (virtualbox, 0)
laravel/homestead (vmware_desktop, 0)vagrant up的时候提示
Box ‘laravel/homestead’ could not be found. Attempting to find and install…
搜了下，可以通过json指定meta，再加到Vagrant中，在box文件所在的目录中创建metadata.json：
|
|
|
|
再执行 vagrant up， 虚机正常起来了，中间有红色的报错信息，目录没挂上
folders:
- map: ~/Code
to: /home/vagrant/Code
本地没有~/Code目录，新建Code目录后，vagrant destroy Homestead-7, 再vagrant up创建虚机；在本地Code目录下新建index.html，vagrant ssh连上虚机后，查看/home/vagrant/Code/下同步出现了index.html，但index.html是访问不到的，默认Homestead.yaml中的sites root是指向/home/vagrant/Code/Laravel/public。
为了方便连虚机，设置命令alias：
|
|
安装 Laravel
需要先安装composer，再全局安装Laravel 安装器，
|
|
再将$HOME/.composer/vendor/bin 加到系统PATH，否则不能在任意路径调用 laravel 命令
vi ~/.bash_profile #增加一行export PATH="$HOME/.composer/vendor/bin:$PATH"
:wq,再source一下
source ~/.bash_profile
进入尾声，laravel new 命令创建一个新的 Laravel 应用

查看目录结构：
|
|
修改hosts，增加一条记录,ip和Homestead.yaml中的对应
|
|
访问 homestead.app 提示 No such files 之类的错误，查看日志/var/log/nginx/homestead.app-error.log：都是找不到/home/vagrant/Code/laravel/public，
生成的Laravel应用目录为blog，修改Homestead.yaml中的sites to /home/vagrant/Code/blog/public。
vagrant reload 修改后的配置未能生效，只好暴力点vagrant destroy homestead-7，再vagrant up；
再次访问ok了，修改welcome.blade.php试下效果：
