window7环境下配置nginx+tomcat+memcached集群

From：http://blog.csdn.net/luckykapok918/article/details/39500545

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

  windows7

  nginx-1.7.4

 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：

修改nginx的conf文件下的nginx.txt配置文件

}

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：

 <!--  修改原port端口：8005 俩个tomcat不能重复，端口随意，别太小-->
 <Server port="18006" shutdown="SHUTDOWN">

 
   第二处端口修改：

 <!-- 原port="8080" tomcat监听端口，随意设置，别太小 -->
 <Connector port="18081" protocol="HTTP/1.1"
                connectionTimeout="20000"
                redirectPort="8443" />

 

   第三处端口修改：

 <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

 

   第四处修改：Engine元素增加jvmRoute属性：

 <Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat1">

 

     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：

 <!--  修改原port端口：8005 俩个tomcat不能重复，端口随意，别太小-->
 <Server port="18007" shutdown="SHUTDOWN">

 
   第二处端口修改：

 <!-- 原port="8080" tomcat监听端口，随意设置，别太小 -->
 <Connector port="18080" protocol="HTTP/1.1"
                connectionTimeout="20000"
                redirectPort="8443" />

 

   第三处端口修改：

 <Connector port="8010" protocol="AJP/1.3" redirectPort="8443" />

 

   第四处修改：Engine元素增加jvmRoute属性：

 <Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat2">

 

   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"
   />

	<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>

   <span style="color:#000099;"> javolution策略模式</span>

    sticky="false"
    sessionBackupAsync="false"
    lockingMode="uriPattern:/path1|/path2"
    requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js)$"
    transcoderFactoryClass="de.javakaffee.web.msm.serializer.javolution.JavolutionTranscoderFactory"
    />

    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：
kryo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.*" %>
<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>

          <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：
