最近公司的IIS服务器总是宕机，自己对运维知识又很欠缺，听了一些介绍决定硬着头皮上，架设一个haproxy负载到后端两个IIS.这里总结一下经验吧！
首先用yum命令安装haproxy这个很简单，说一下流程吧！先安装gcc编译器
# yum install gcc
# wget http://haproxy.1wt.eu/download/1.4/src/ haproxy-1.4.24.tar.gz
# tar zxvf haproxy-1.4.24
# make install
# mkdir -p /usr/local/haproxy/etc
# mkdir -p /usr/local/haproxy/sbin
# cp examples/haproxy.cfg /usr/local/haproxy/etc
# ln -s /usr/local/sbin/haproxy /usr/local/haproxy/sbin/haproxy
到这里安装的步骤就基本完成了，下面开始要进行配置文件的修改，在网上找了许多文件尝试不成功，最后找到了一篇博文用ACL的方式配置成功，自己也不理解具体的含义。姑且用自己的理解先做着吧！
