安装Laravel5.2

通过 Composer 创建项目并自动下载Laravel框架

composer create-project --prefer-dist laravel/laravel laravel5

以上则已经为我们下载好了laravel框架，如果顺利应该继续往下执行并安装其他依赖。
安装过程中可能报错，因为composer走的国外地址可能被墙。
以下为报错信息：

Loading composer repositories with package information

解决方法：更换网络节点，或者使用vpn。
在已下载下来的（laravel5.2）项目中执行 composer update 或者 composer install

nginx 配置

server {
    listen       80;
    server_name  laravel;
    root /Users/wenji/project/laravel5.2/public;
    index  index.html index.htm index.php;

    access_log  /Users/wenji/project/logs/laravel5.2_access.log;

    # php rewrite
    location / {

    try_files $uri $uri/ /index.php?$query_string;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80

随机字串作为应用的秘钥（key）
php artisan key:generate
这个 key 还可以在 .env 环境配置文件中设置

➜  laravel5.2 git:(master) php artisan key:generate
Application key [base64:66bDiQEpVqzyL6CsWBcIN5IYnJHa3vqezUtph+hHGXc=] set successfully.
