经过上述的步骤，传说中的LAMP架构就这样搭建完成了

顺便提下

yum install httpd

安装的httpd配置在/etc/httpd/conf/httpd.conf 中

如：

ServerName localhost:80

Listen 192.168.1.112:80

另外学一门语言总得把相关的框架给玩一下：

yii为例子（yii的官网：https://github.com/yiisoft/yii）：

执行以下命令：

  1. mkdir YiiPath
  2. cd YiiPath/
  3. git clone https://github.com/yiisoft/yii.git

然后就可以看到如此美丽的配置页面了

CI框架为例子（官网：http://codeigniter.org.cn/）：

  1. wget https://codeload.github.com/bcit-ci/CodeIgniter/zip/3.0.0
  2. unzip

然后就也可以看到如此美丽的配置页面了

http://192.168.1.112/CodeIgniter-3.0.0/

或者到github上面去找（https://github.com/bcit-ci/CodeIgniter）

  1. mkdir ci
  2. cd ci/
  3. git clone https://github.com/bcit-ci/CodeIgniter.git

http://192.168.1.112/ci/CodeIgniter/
