1.composer安裝命令：

Writing lock file

Generating autoload files

直接使用laravel命令有錯，需要手動新增許可權及給命令

~/.config/composer/vendor# chmod +x laravel/installer/laravel 

~/.config/composer/vendor# ln laravel/installer/laravel /usr/bin/laravel

訪問路徑為/blog/public

編輯 環境變數檔案 vi /etc/environment

新增路徑 /root/.config/composer/vendor/bin

這樣就可以全域性使用laravel命令

2.詳細查看了官方開發環境Homestead，覺得在已經有云伺服器的情況下，可以不用安裝，用phpstorm配置遠端同步也一樣開發方便。

3.美化url，nginx 配置檔案新增紅色部分：

location / {
            root   html;
            index  index.html index.htm index.php;
                        add_header 'Access-Control-Allow-Origin' '*';
            try_files $uri $uri/ /index.php?$query_string;
        }
