Laravel教程：laravel 4安装及入门

一.安装Composer
首先你需要安装Composer,Composer是PHP依赖管理工具，Laravel框架就是使用 Composer 执行安装和依赖管理。 
注：
(1)若安装Composer出错，在php.ini中开启php_openssl，php_fileinfo扩展，因为Laravel需要。
(2)安装过程中，选择正确的php.exe位置

二.安装Laravel
Composer安装完成后，在cmd中，你的网站目录执行下面命令即可：

<ol class="linenums" style="margin: 0px; padding: 0px 5px; border-width: 0px 0px 0px 30px; border-left-style: solid; border-left-color: rgb(200, 200, 200); list-style: decimal-leading-zero; color: rgb(0, 0, 0);"><li class="L0" style="margin: 0px; padding: 0px; border: 0px;"><span class="pln">composer create</span><span class="pun" style="color: rgb(102, 102, 0);">-</span><span class="pln">project laravel</span><span class="pun" style="color: rgb(102, 102, 0);">/</span><span class="pln">laravel your</span><span class="pun" style="color: rgb(102, 102, 0);">-</span><span class="pln">project</span><span class="pun" style="color: rgb(102, 102, 0);">-</span><span class="pln">name</span></li></ol>

Composer会自动帮你下载Laravel及安装。


三.部署虚拟主机
例如我的项目名称是project：

<ol class="linenums" style="margin: 0px; padding: 0px 5px; border-width: 0px 0px 0px 30px; border-left-style: solid; border-left-color: rgb(200, 200, 200); list-style: decimal-leading-zero; color: rgb(0, 0, 0);"><li class="L0" style="margin: 0px; padding: 0px; border: 0px;"><span class="tag" style="color: rgb(0, 0, 136);"><VirtualHost</span><span class="pln"> *:80</span><span class="tag" style="color: rgb(0, 0, 136);">></span></li><li class="L1" style="margin: 0px; padding: 0px; border: 0px; background-color: rgb(239, 239, 239);"><span class="pln">DocumentRoot "E:/www/project/public"</span></li><li class="L2" style="margin: 0px; padding: 0px; border: 0px;"><span class="pln">ServerName laravel.dev</span></li><li class="L3" style="margin: 0px; padding: 0px; border: 0px; background-color: rgb(239, 239, 239);"><span class="pln">ErrorLog "logs/laravel.log"</span></li><li class="L4" style="margin: 0px; padding: 0px; border: 0px;"><span class="pln">CustomLog "logs/laravel.log" common</span></li><li class="L5" style="margin: 0px; padding: 0px; border: 0px; background-color: rgb(239, 239, 239);"><span class="tag" style="color: rgb(0, 0, 136);"></VirtualHost></span></li></ol>

当然，也需要在你的hosts中绑定域名：

<ol class="linenums" style="margin: 0px; padding: 0px 5px; border-width: 0px 0px 0px 30px; border-left-style: solid; border-left-color: rgb(200, 200, 200); list-style: decimal-leading-zero; color: rgb(0, 0, 0);"><li class="L0" style="margin: 0px; padding: 0px; border: 0px;"><span class="lit" style="color: rgb(0, 102, 102);">127.0</span><span class="pun" style="color: rgb(102, 102, 0);">.</span><span class="lit" style="color: rgb(0, 102, 102);">0.1</span><span class="pln">       laravel</span><span class="pun" style="color: rgb(102, 102, 0);">.</span><span class="pln">dev</span></li></ol>

至此，安装完成：

四.实现Hello World
通过路由实现打印Hello World,在app/routes.php中新增：

<ol class="linenums" style="margin: 0px; padding: 0px 5px; border-width: 0px 0px 0px 30px; border-left-style: solid; border-left-color: rgb(200, 200, 200); list-style: decimal-leading-zero; color: rgb(0, 0, 0);"><li class="L0" style="margin: 0px; padding: 0px; border: 0px;"><span class="typ" style="color: rgb(102, 0, 102);">Route</span><span class="pun" style="color: rgb(102, 102, 0);">::</span><span class="kwd" style="color: rgb(0, 0, 136);">get</span><span class="pun" style="color: rgb(102, 102, 0);">(</span><span class="str" style="color: rgb(0, 136, 0);">'test'</span><span class="pun" style="color: rgb(102, 102, 0);">,</span><span class="pln"> </span><span class="kwd" style="color: rgb(0, 0, 136);">function</span><span class="pun" style="color: rgb(102, 102, 0);">()</span></li><li class="L1" style="margin: 0px; padding: 0px; border: 0px; background-color: rgb(239, 239, 239);"><span class="pun" style="color: rgb(102, 102, 0);">{</span></li><li class="L2" style="margin: 0px; padding: 0px; border: 0px;"><span class="pln">    </span><span class="kwd" style="color: rgb(0, 0, 136);">return</span><span class="pln"> </span><span class="str" style="color: rgb(0, 136, 0);">'Hello World!'</span><span class="pun" style="color: rgb(102, 102, 0);">;</span></li><li class="L3" style="margin: 0px; padding: 0px; border: 0px; background-color: rgb(239, 239, 239);"><span class="pun" style="color: rgb(102, 102, 0);">});</span></li></ol>

因为Laravel模板使用的是Blade，所以在后面的教程才介绍Controller或view相关！
