< 用 Apache 构建 HTTP 服务器 > （最近更新日：2006/08/26）
前 言
对于大多数的网络服务器，最广泛的功能就是开通HTTP服务，达到开放和发布网站的目的。目前绝大多数的网络交互程序，例如论坛、社区等等也是基于HTTP而建立的。
在这里，我们通过Web服务器软件中使用量超过半数的自由软件Apache，来构建一台能够满足实际要求的多功能Web服务器，使它能够在我们发布网页的基础上，实现可以运行Perl、PHP的等等语言编写的交互程序，以及在虚拟主机、保密方面的功能。
安装HTTP（Apache）服务器及相关组件
首先来安装Apache服务器及相关组件。这里使用yum命令来在线安装。

为了使PHP应用程序的执行效率大幅度提高，我们安装Zend。

然后会出现对话方式的安装向导，图样如下：
[1] 选择OK，进入安装向导。
