PHP框架学习之Laravel安装

自从接触PHP以来一直使用Yii,感觉Yii实现功能比较简单，是一个很不错的框架。最近由于工作的原因开始研究Laravel5，不得不说我在第一步安装就被坑着了，下面就是我痛苦的学习成果。Laravel对我来说完全是新东西，如果内容有误，烦请留言或QQ我，帮我纠正错误，感激不尽！！！

1.首先安装php,最好5.6以上版本
  (1)windows安装composer过程中需要指定php.exe的路径
  (2)linux安装composer过程中需要利用php-cli功能

2.安装composer
  (1)windows安装composer
       a.windows下载composer软件,然后next直到完成
       b.win+R => 输入cmd => 输入composer, 如果出现composer字体表示安装成功
  (2)linux安装composer
       a.$ curl -sS https://getcomposer.org/installer | php
       b.此时在~/.composer下应该会产生composer.phar 这个文件
       c.$ mv  composer.phar  /usr/local/bin/composer
       d.将composer.phar移动成/usr/local/bin/composer全局下，以后可以直接使用composer,而不需要php  composer.phar
       e.$ composer
 
3.修改composer镜像源（建议第一种）
   (1)将配置信息添加到 composer 的配置文件 config.json 中（系统全局配置）
　　　 $composer config -g repositories.packagist composer http://packagist.phpcomposer.com

   (2)将配置信息添加到单个项目的 composer.json 文件中（单个项目配置）   注意最后几行repositories

    "repositories": [
        {"type": "composer", "url": "http://packagist.phpcomposer.com"},
        {"packagist": false}
    ]
}

4.安装laravel
$ composer create-project laravel/laravel learnlaravel5

5.如果是mac或linux系统需要对storage赋予777权限
$ sudo chmod -R 777 learnlaravel5/storage

6.浏览器访问localhost/learnlaravel5/public,出现Laravel5表示laravel5安装成功
