本文详细介绍了如何手工和使用脚本部署LNMP（Nginx、PHP、MySQL）架构，包括WordPress和Wecenter的安装配置。在手工部署中，涉及Nginx的安装、DNS服务器配置、解决502错误等问题。而在脚本自动搭建部分，通过expect实现免交互登录，加入keepalived以实现高可用。同时，文中提供了常见报错的处理方法。

两种部署方式：

一、手工搭建

分析：最终效果，通过Nginx搭建两个网站blog和zh，通过域名访问。在lnmp的基础上，域名访问，要么搭建DNS服务器，要么修改主机hosts文件。

1、安装Nginx：
进入yum目录配置网络源，Nginx官网、清华源均可，以清华源为例。
