1、拓撲圖css

2、環境安裝html

安裝memcached的直接yumjava

[root@70sec ~]# yum -y install memcachedlinux

[root@70sec ~]# service memcached startweb

Starting memcached: [ OK ]apache

[root@70sec ~]# ss -anlpt | grep memcachedvim

LISTEN 0 128 :::11211 :::* users:(("memcached",26347,27))tomcat

LISTEN 0 128 *:11211 *:* users:(("memcached",26347,26))session

[root@70sec ~]# app

由於tomcat依賴於java環境因此先安裝jdk，（tomcat A B 都相同）

[root@90sec src]# rpm -ivh jdk-7u9-linux-x64.rpm

[root@90sec src]# vim /etc/profile.d/java.sh

JAVA_HOME=/usr/java/jdk1.7.0_09

PATH=$JAVA_HOME/bin:$PATH

export JAVA_HOME

[root@90sec src]# source /etc/profile.d/java.sh

安裝tomcat

[root@90sec src]# tar xf apache-tomcat-7.0.42.tar.gz -C /usr/local/

[root@90sec src]# cd /usr/local/

[root@90sec local]# ln -sv apache-tomcat-7.0.42/ tomcat

`tomcat' -> `apache-tomcat-7.0.42/'

[root@90sec tomcat]# vim /etc/profile.d/tomcat.sh

export CATALINA_HOME=/usr/local/tomcat

export PATH=$CATALINA_HOME/bin:$PATH

[root@90sec tomcat]# source /etc/profile.d/tomcat.sh

[root@90sec tomcat]# catalina.sh version #查看版本

[root@90sec tomcat]# catalina.sh start #啓動

修改tomcat的配置文件（A和B相同）

配置Session共享Memcache,分別放在兩個tomcat的lib下

javolution-5.4.3.1.jar

memcached-session-manager-1.8.1.jar

memcached-session-manager-tc7-1.8.1.jar z

msm-javolution-serializer-1.8.1.jar

spymemcached-2.10.2.jar

[root@90sec tomcat]# vim conf/context.xml

<Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"

memcachedNodes="n1:192.168.83.134:11211"

failoverNodes="n1"

requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js)$" transcoderFactoryClass="de.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory"

</Context>

爲tomcat提供測試頁

#### tomcat A##########

[root@90sec tomcat]# mkdir -pv /usr/local/tomcat/webapps/test/WEB-INF/{classes,lib}

[root@90sec tomcat]# vim /usr/local/tomcat/webapps/test/index.jsp

<%@ page language="java" %>

<html>

<head><title>TomcatA</title></head>

<body>

<h1><font color="red">TomcatA.magedu.com</font></h1>

<tr>

<td>Session ID</td>

<% session.setAttribute("magedu.com","magedu.com"); %>

</tr>

<tr>

<td>Created on</td> <td><%= session.getCreationTime() %></td>

</tr>

</table>

</body>

</html>

~ #####tomcat B##########

mkdir -pv /usr/local/tomcat/webapps/test/WEB-INF/{classes,lib}

[root@80sec tomcat]# vim /usr/local/tomcat/webapps/test/index.jsp

<%@ page language="java" %>

<html>

<head><title>TomcatB</title></head>

<body>

<h1><font color="red">TomcatB.magedu.com</font></h1>

<tr>

<td>Session ID</td>

<% session.setAttribute("magedu.com","magedu.com"); %>

</tr>

<tr>

<td>Created on</td>

</tr>

</table>

</body>

</html>

安裝httpd配置反代

[root@60sec ~]# yum -y install httpd
