安装composer

sudo apt-get install libmcrypt libmcrypt-devel

sudo apt-get install php-mbstring

sudo apt-get install php-xml
curl -sS https://getcomposer.org/installer | php
mv composer.phar /usr/local/bin/composer        
composer -V

安装laravel

sudo apt-get install php-mbstring

composer create-project --prefer-dist laravel/laravel blog "5.2.*"

composer config -g repo.packagist composer https://packagist.phpcomposer.com

2、设置目录权限：对于storage文件夹和bootstrap/cache必须设置为服务器可以写入的权限（window下可以忽略）
5、（补充）如果你没有使用Composer安装(直接下载放到web服务器的网站根目录下)，还需要做两步
a、将.env.example文件复制一份，改名为.env
b、修改秘钥，这串秘钥存放在.env全局配置文件中，修改方法很简单只需在终端执行下面的命令(更安全有关需要修改)
php artisan key:generate
