这几天研究了一下Nginx和tomcat的集群环境搭建，同时支持HTTP请求和HTTPS请求，研究了一下，整理一下，分享给大家。还是有很多不足的地方，大家发现问题，希望多多指正。话不多说，上代码~
因为研究的条件有限，我是在本机上搭建两个Tomcat进行模拟的。
一、环境准备
1.Tomcat7：http://tomcat.apache.org/download-70.cgi
2.Nginx1.7.4：http://nginx.org/en/download.html
3.Memcached：http://www.newasp.net/soft/63735.html 实在没有找到别的太好的下载地址~
4.必备的JAR包：
