1.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 ).
tomcat分别为apache-tomcat-6.0.41 (端口 18081 )和apache-tomcat-7.0.54 (端口 18080),主要是测试不同版本的tomcat的配置
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:
http://blog.csdn.net/luckykapok918/article/details/39501259
修改nginx的conf文件下的nginx.txt配置文件
#user nobody; worker_processes 1; #error_log logs/error.log; #error_log logs/error.log notice; #error_log logs/error.log info; #pid logs/nginx.pid; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; #log_format main '$remote_addr - $remote_user [$time_local] "$request" ' # '$status $body_bytes_sent "$http_referer" ' # '"$http_user_agent" "$http_x_forwarded_for"'; #access_log logs/access.log main; sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; #gzip on; upstream localhost { #ip_hash #ip_hash; server localhost:18081; server localhost:18080;

1.2.安装memcache,具体操作见下面:

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)
<Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager" memcachedNodes="n1:localhost:11211,n2:localhost:11212" sticky="false" sessionBackupAsync="false" lockingMode="uriPattern:/path1|/path2" requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js)$" transcoderFactoryClass="de.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory" />
<span style="color:#000099;"> javolution策略模式</span>
<pre name="code" class="html"> <Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager" memcachedNodes="n1:localhost:11211,n2:localhost:11212" sticky="false" sessionBackupAsync="false" lockingMode="uriPattern:/path1|/path2" requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js)$" transcoderFactoryClass="de.javakaffee.web.msm.serializer.javolution.JavolutionTranscoderFactory" />d. tomcat6和tomcat7 lib文件夹下添加的 MSM(memcached-session-manager) 相关jar:
<img src="http://img.blog.csdn.net/20140923223300359?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvbHVja3lrYXBvazkxOA==/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/SouthEast" alt="" />
<span style="color:#000099;">javolution策略模式所需jar包</span>
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.*" %> <html><head><title>Cluster App Test</title></head> <body> Server Info: <% out.println(request.getLocalAddr() + ":" + request.getLocalPort()); %> <br><br> <% out.println("<br> ID " + session.getId()+"<br>"); String dataName = request.getParameter("dataName"); if (dataName != null && dataName.length() > 0) { String dataValue = request.getParameter("dataValue") ; session.setAttribute(dataName, dataValue); } out.print("<b>Session list</b> <br>"); Enumeration e = session.getAttributeNames(); while (e.hasMoreElements()) { String name = (String)e.nextElement(); String value = session.getAttribute(name).toString(); out.println( name + " = " + value+"<br>"); System.out.println( name + " = " + value); } %> <form action="index.jsp" method="POST"> name:<input type=text size=20 name="dataName"> <br> key:<input type=text size=20 name="dataValue"> <br> <input type=submit> </form> </body> </html>
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:
