環境介紹：兩臺win2008_x64位主機+jdk7_x64位分別爲A主機IP:192.168.7.100、B主機IP：192.168.7.101php

1、首先安裝memcached(A主機、B主機都須要安裝)css

下載地址：http://download.csdn.net/detail/ttyyadd/9414586html

下載完成後解壓到本地磁盤。java

打開cmd命令窗口進行到memcached.exe所在目錄，而後執行下面命令進行安裝nginx

memcached.exe -d install

安裝後並無啓動須要到服務管理裏面找到memached服務將它啓動。web

2、下面開始配置tomcat6 緩存

一、首先下載所須要jartomcat

將下載的jar放到tomcat目錄下的lib文件夾下面session

http://download.csdn.net/detail/ttyyadd/9414529app

二、開始配置（A主機:192.168.7.100）context.xml

<Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"
    memcachedNodes="n1:192.168.7.100:11211,n2:192.168.7.101:11211"
    failoverNodes="n2"
    requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js)$"
    transcoderFactoryClass="de.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory"
    />

開始配置（B主機:192.168.7.101）context.xml

<Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"
    memcachedNodes="n1:192.168.7.100:11211,n2:192.168.7.101:11211"
    failoverNodes="n1"
    requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js)$"
    transcoderFactoryClass="de.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory"
    />

這裏要注意的是failoverNodes屬性，該屬性值要指向（非本機的）另一臺主機。

三、新建一個test.jsp頁面,分別放到A主機和B主機的Tomcat 下的ROOT目錄

<%@ page language="java" %>
<%@ page import="java.util.*" %>

<html><head><title></title></head>

<body>

<%

System.out.println(session.getId());

out.println("<br> HostA HostB, SESSION ID:" + session.getId()+"<br>");

%>

</body>

</html>

3、配置nginx

一、首先下載 nginx安裝包

　　http://nginx.org/

二、開始配置nginx

打開安裝目錄的nginx.conf。個人安裝目錄爲（D:\nginx-1.9.9\conf\nginx.conf）

#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;
}

    include       mime.types;
    default_type  application/octet-stream;

    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    keepalive_timeout  65;

    #gzip  on;

   upstream mysvr { #weigth參數表示權值，權值越高被分配到的概率越大 #1.down 表示單前的server暫時不參與負載
      #2.weight 默認爲1.weight越大，負載的權重就越大。     
      #3.backup： 其它全部的非backup機器down或者忙的時候，請求backup機器。因此這臺機器壓力會最輕。  
      #server 192.168.1.116  down;
      #server 192.168.1.116  backup;
      server 192.168.7.100:8080  weight=1;
      server 192.168.7.101:8080  weight=1; } 

    server {
        listen       80;
