nginx做调度（自身用dns轮询保证高可用）,varnish做后端的cache

本文主要是介绍nginx做调度（自身用dns轮询保证高可用）,varnish做后端的cache，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

Nginx + varnish 构建高可用CDN节点集群

作者：随风发布于：2012-6-19 10:29 Tuesday 分类：linux运维

OSAPUB 出品的集群方案，旨在抛砖引玉，给广大朋友提供高可用CDN节点集群方案
转载请标明出去：http://bbs.osapub.com/thread-3370-1-1.html

一、环境描述

Linux server A (CentOS release 5.8 Final) 实IP:192.168.4.97 虚IP：192.168.4.96
Linux server B (CentOS release 5.8 Final) 实IP:192.168.4.99 虚IP：192.168.4.98

域名环境（DNS轮询解析到虚IP）：
server.osapub.com 192.168.4.96
server.osapub.com 192.168.4.98

二、简单架构示意图

描述：前端两台NGINX做DNS轮询，通过虚IP漂移+HA监控脚本相结合，实现前端两台NGINX高可用，利用NGINX反向代理功能对后端varnish实现高可用集群。

三、软件环境搭建
3.1 编译安装nginx

三、配置varnish一些参数说明：
Backend servers
Varnish有后端（或称为源）服务器的概念。后端服务器是指Varnish提供加速服务的那台，通常提供内容。
第一件要做的事情是告诉Varnish，哪里能找到要加速的内容。
vcl_recv
vcl_recv是在请求开始时调用的。完成该子程序后，请求就被接收并解析了。用于确定是否需要服务请求，怎么服务，如果可用，使用哪个后端。
在vcl_recv中，你也可以修改请求。通常你可以修改cookie，或添加/移除请求头信息。
注意在vcl_recv中，只可以使用请求对象req。

vcl_fetch
vcl_fetch是在文档从后端被成功接收后调用的。通常用于调整响应头信息，触发ESI处理，万一请求失败就换个后端服务器。
在vcl_fecth中，你还可以使用请求对象req。还有个后端响应对象beresp。Beresp包含了后端的HTTP头信息。

varnish 3.X 配置参考文档：http://anykoro.sinaapp.com/?p=261

编辑：/usr/local/varnish/vcl.conf ，文件不存在则创建。注意：Server A 与server B 配置一致！
