二、memcached安装

yum -y install libevent libevent-devel

tar zxvf memcached-1.4.22.tar.gz

cd memcached-1.4.22

./configure --prefix=/usr/local/memcached

make && make install

?

启动memcached ip为172.19.0.102 根据自己的环境 端口11211可以根据自己需要修改不同端口

?

/usr/local/memcached/bin/memcached -d -m 1024 -u root -l 172.19.0.102 -p 11211 -c 1024 -P /tmp/memcached.pid

?

测试一下如下说明成功

telnet 172.19.0.102 11211

?

Trying 172.19.0.102...

Connected to 172.19.0.102.

Escape character is '^]'.

?

三、安装jdk

tar zxvf jdk-7u21-linux-x64.tar.gz

mv jdk1.7.0_21 /opt/jdk

配置vi /etc/profile 增加到环境变量中

在最后面增加

?

JAVA_HOME=/opt/jdk

PATH=$JAVA_HOME/bin:$PATH

CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

export JAVA_HOME

export PATH

export CLASSPATH

?

生效环境变量

source /etc/profile

?

java -version 查看是版本是否生效

java version "1.7.0_21"

Java(TM) SE Runtime Environment (build 1.7.0_21-b11)

Java HotSpot(TM) 64-Bit Server VM (build 23.21-b01, mixed mode)

?

四、安装与配置tomcat

1.安装tomcat

tar zxvf tomcat7.tar.gz

mv apache-tomcat-7.0.29 /opt/tomcat1

2.添加mem和msm的依赖jar包

把包下载后上传/opt/tomcat1/lib/ 目录下

?

3、配置tomcat

cd /opt/tomcat1/conf

vi context.xml

增加 之间 注意：172.19.0.102 11211 是memcached端口

memcachedNodes="n1:172.19.0.102:11211"

requestUriIgnorePattern=".*/.(png|gif|jpg|css|js|swf|flv)$"

sessionBackupAsync="false"

sessionBackupTimeout="100"

transcoderFactoryClass="de.javakaffee.web.msm.serializer.javolution.JavolutionTranscoderFactory"

copyCollectionsForSerialization="false"/>

?

修改vi server.xml

五、配置tomcat集群上面配置好后拷贝一份

cp -r tomcat1 tomcat2

cd tomcat2/conf/

修改vi server.xml配置把端口配置不同的

1. 找到如下把8005修改成8006

-->

2.找到如下把8080修改成8090根据自己来配置，修改后的8090与nginx配置一样

-->

connectionTimeout="20000"

redirectPort="8443" />

3.找到如下把8009修改成8010

4. 找到如下把tomcat1修改成tomcat2

-->

?

六、启动tomcat集群

启动tomcat1

sh /opt/tomcat1/bin/startup.sh

启动tomcat2

sh /opt/tomcat2/bin/startup.sh

?

netstat -tunlp查看tomcat集群启动成功

tcp 0 0 :::8080 :::* LISTEN 22911/java

tcp 0 0 :::8090 :::* LISTEN 22946/java

查看8080与8090说明成功

七、启动 nginx

/usr/local/nginx/sbin/nginx 启动

/usr/local/nginx/sbin/nginx -s reload 重启

测试session是否共享

1.cd /opt/tomcat1/webapps/ROOT/

mkdir test

cd test

vi index.jsp

?

<%@ page contentType="text/html; charset=GBK" %>

?

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

?

?

?

?

?

<%

?

//HttpSession session = request.getSession(true);

?

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

?

out.println("
SESSION ID:" + session.getId()+"
");

?

%>

?

?

?

2.cd /opt/tomcat2/webapps/ROOT/ 把tomcat1 test目录拷贝过来

cp -r /opt/tomcat1/webapps/ROOT/test ./

?

打开网页
