1.安装pcre

tar zxvf pcre-8.36.tar.gz

cd pcre-8.36

./configure

make && make install

2.安装zlib

cd zlib-1.2.8

./configure

make && make install

3.安装openssl

                  upstream wazert.com {

            server 127.0.0.1:8080;  #tomcat1后面安装配置

                    server 127.0.0.1:8090;   #tomcat2

         }

                  

        server {

              expires 30d;

                              proxy_cache_key $host$uri$is_args$args;

        }

        }

}

 

 

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 ip172.19.0.102 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memmsm的依赖jar

技术分享

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<Context></Context>之间      注意:172.19.0.102 11211 memcached端口

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

                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

<!-- You should set jvmRoute to support load-balancing via AJP ie :

    <Engine name="Catalina" defaultHost="localhost" jvmRoute="jvm1">

    -->

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

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

-->

<Server port="8005" shutdown="SHUTDOWN">

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

   -->

    <Connector port="8090" protocol="HTTP/1.1"

               connectionTimeout="20000"

               redirectPort="8443" />

3.找到如下把8009修改成8010

<!-- Define an AJP 1.3 Connector on port 8009 -->

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

4. 找到如下把tomcat1修改成tomcat2

-->

    <Engine name="Catalina" defaultHost="localhost" jvmRoute="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80808090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.*" %>

 

<html><head><title>Cluster Test</title></head>

 

<body>

 

<%

 

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

 

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

 

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

 

%>

 

</body>

 

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

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

刷新几次看看session iD不变,就成功了,如果变了可能配置问题。以上图说明session共享了

telnet 172.19.0.102 11211
