首先整个安装软件说明 :windows7 , nginx-1.7.4 ,memcache1.4.13 ,分别在本机创建了2个服务memcached1 (端口 11211 )和 memcached2(端口 11212 ).
1.首先整个安装软件说明
1.1 首先安装nginx,本人使用的版本是nginx-1.7.4,并且把nginx作为系统服务,具体操作见下面:

修改nginx的conf文件下的nginx.txt配置文件

}
server {
listen 80;
server_name localhost;
location / {
proxy_connect_timeout 3;

proxy_pass http://localhost;
}

# redirect server error pages to the static page /50x.html
#

location = /50x.html {
root html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80

# ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on;
# location / {
# root html;
# index index.html index.htm;
# }
#}
}
1.2.安装memcache,具体操作见下面:
http://blog.csdn.net/luckykapok918/article/details/10005583
1.3.解压tomcat免安装压缩包到,具体如下图:
因为是在一台机器上做测试,所以还需对tomcat的配置文件端口、jvm等做修改,以满足一台机器测试所用:
a. tomcat6需要配置的文件,如下:
server.xml文件中4处修改(如果是安装在不同机器上则不需要)
第一处端口修改:
第二处端口修改:
第三处端口修改:
第四处修改:Engine元素增加jvmRoute属性:
b. tomcat7需要配置的文件,如下:
server.xml文件中4处修改(如果是安装在不同机器上则不需要)
第一处端口修改:
第二处端口修改:
第三处端口修改:
第四处修改:Engine元素增加jvmRoute属性:
c. tomcat6和tomcat7都需要修改的:
context.xml文件中 增加
kryo策略模式(一般来说采用kryo模式下的Non-sticky Session方式,性能最好)
javolution策略模式
d. tomcat6和tomcat7 lib文件夹下添加的MSM(memcached-session-manager) 相关jar:
kryo策略模式所需jar包
javolution策略模式所需jar包
1.4.测试web工程ssm,只需要一个index.jsp页面就可以了
<%@ page contentType="text/html; charset=GBK" %>
<%@ page import="java.util.*" %>
Cluster App Test
Server Info:
<%
out.println(request.getLocalAddr() + ":" + request.getLocalPort());
%>
<%
out.println("
ID " + session.getId()+"
");
String dataName = request.getParameter("dataName");
if (dataName != null && dataName.length() > 0) {
String dataValue = request.getParameter("dataValue") ;
session.setAttribute(dataName, dataValue);
}
out.print("Session list
");
Enumeration e = session.getAttributeNames();
while (e.hasMoreElements()) {
String name = (String)e.nextElement();
String value = session.getAttribute(name).toString();
out.println( name + " = " + value+"
");
System.out.println( name + " = " + value);
}
%>
所有软件安装配置好后,先启动nginx,memcached,最好分别启动tomcat6,tomcat7,都没报错,则配置成功。
2.tomcat集群session共享验证测试
2.1 ,验证tomcat6启动成功:
2.2 ,验证tomcat7启动成功:
2.3,验证nginx转发成功:
2.4,验证tomcat session共享成功:
kryo策略:
首先登陆的是tomcat6的服务器,现在关掉tomcat6服务器,然后再刷新页面, 如果ID的值相同且Session List中值也存在,说明Session是被共享的。
kryo策略:
javolution策略:
首先登陆的是tomcat7的服务器,现在关掉tomcat7服务器,然后再刷新页面,如果ID的值相同且Session List中值也存在,说明Session是被共享的。
javolution策略:
