composer問題
/usr/bin/env: php: No such file or directory
因為是編譯安裝的php7，php的可執行文件不在/usr/bin，而在/usr/local/php7/bin，所以可以創建鏈接過去
ln -s /usr/bin/php /usr/local/php7/bin/php

安裝laravel5.4

• 方法一-通過 Laravel 安裝工具
  composer global require "laravel/installer"
laravel new blog
• 方法二-通過 Composer Create-Project
  composer create-project --prefer-dist laravel/laravel blog

Nginx配置Laravel

 user nginx nginx;
 worker_processes  1;

 pid        logs/nginx.pid;
 events {
     worker_connections  1024;
 }

 http {
     include       mime.types;
     default_type  application/octet-stream;

     sendfile on;
     tcp_nopush on;

     keepalive_timeout  65;
     gzip on;

     server
     {
         listen 80;
         server_name localhost;
         root /home/nginx/project/lavue/public;
         index index.html index.htm index.php;

         try_files $uri $uri/ @rewrite;
         location @rewrite {
             rewrite ^/(.*)$ /index.php?_url=/$1;
         }

         location ~ .*\.(php|php5)?$
         {
                 fastcgi_pass 127.0.0.1:9000;
                 fastcgi_index index.php;
                 fastcgi_split_path_info       ^(.+\.php)(/.+)$;
                 fastcgi_param PATH_INFO       $fastcgi_path_info;

                 fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                 include                       fastcgi_params;
         }

         location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
         {
                 expires 30d;
         }

         location ~ .*\.(js|css)?$
         {
                 expires 1h;
         }

         location ~ /\.ht {
             deny all;
         }
     }
 }

【問題】配置nginx的root為 /home/xy/project/lavue/public，打開localhost，顯示404或者403
【解決】雖然project的owner是nginx，但是xy的owner是xy，可能是權限的問題，新建/home/nginx/project/，chown -R nginx nginx, chgrp -R nginx nginx，修改root路徑，解決正常顯示
