composer问题
/usr/bin/env: php: No such file or directory
因为是编译安装的php7，php的可执行文件不在/usr/bin，而在/usr/local/php7/bin，所以可以创建链接过去
ln -s /usr/bin/php /usr/local/php7/bin/php

安装laravel5.4

• 方法一-通过 Laravel 安装工具
  composer global require "laravel/installer"
laravel new blog
• 方法二-通过 Composer Create-Project
  composer create-project --prefer-dist laravel/laravel blog

Nginx配置Laravel

【问题】配置nginx的root为 /home/xy/project/lavue/public，打开localhost，显示404或者403
【解决】虽然project的owner是nginx，但是xy的owner是xy，可能是权限的问题，新建/home/nginx/project/，chown -R nginx nginx, chgrp -R nginx nginx，修改root路径，解决正常显示
