 实际生产环境中架构用到IIS+haproxy+keepalived+nginx,需要综合整理学习一下。

    折腾半天haproxy,大面上配通,细节上还有很多需要整理。
环境:
    前端:haproxy  IP:192.168.71.128
    后端WEB:
    server01:apache  192.168.71.138(Linux)
    http://192.168.71.138

    server02:apache  192.168.71.135(windows)
    http://192.168.71.135

试验目的:
    前端haproxy为后端两台Web云服务器做负载均衡及灾备冗余。
