<下图来自于网络>

一、memcache

安装包：memcache-2.2.5.tgz

解压

配置

vim ~/.bash_profile
--> PATH=$PATH:$HOME/bin:/usr/local/lnmp/mysql/bin:/usr/local/lnmp/php/bin
source ~/.bash_profile

phpize
./configure --enable-memcache       //编译
make        make install

vim /usr/local/lnmp/php/etc/php.ini
--> 851 extension=memcache.so

cd /memcache-2.2.5
vim memcache.php
-->23 define('ADMIN_PASSWORD','westos');      // Admin Password
28 $MEMCACHE_SERVERS[] = '172.25.50.1:11211'; // add more as an array

cp example.php memcache.php /usr/local/lnmp/nginx/html
yum install memcached -y    //并且打开服务

测试：

二、Tomcat

安装包：

apache-tomcat-7.0.37.tar.gz jdk-7u79-linux-x64.tar.gz

jdk：Java语言的软件开发工具包

tomcat：应用（Java）服务器，是apache的扩展

解压

配置

tar zxf jdk-7u79-linux-x64.tar.gz -C /usr/local/
cd /usr/local
ln -s jdk1.7.0_79/ java
vim /etc/profile
-->  80 export JAVA_HOME=/usr/local/java
81 export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
82 export PATH=$PATH:$JAVA_HOME/bin

测试java包是否安装好，写一个java脚本，再进行编译测试。

vim test.java

–> public class test

{

public static void main(String[] args){

System.out.println(“Hello World!”);

}

}

javac test.java
[root@server1 ~]# java test
Hello world!

tar zxf apache-tomcat-7.0.37.tar.gz -C /usr/local
cd /usr/local
ln -s apache-tomcat-7.0.37/ tomcat
##开启tomcat                      ##为8080端口
##  为tomcat目录下的bin/startup.sh
##  关闭为bin/shutdown.sh
vim /usr/local/lnmp/nginx/conf/nginx.conf
--> 70         location ~ \.jsp$ {
71                 proxy_pass http://172.25.50.1:8080; 72         }

测试是否安装成功：

也可写一个脚本测试：

vim /usr/local/tomcat/webapps/ROOT/test.jsp
-->server1 time is: <%= new java.util.Date() %>

将jar目录中的内容全部放在tomcat下面的lib中，删除掉memcached-session-manager-tc6-1.5.1.jar

vim /usr/local/tomcat/conf/context.xml  //在最后加上
<Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"
memcachedNodes="172.25.50.1:11211,n2:172.25.50.2:11211"
failoverNodes="n1" #在node2上此项设置为“n2”
requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js)$"
transcoderFactoryClass="de.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory"
/>
启动该服务的命令为 /usr/local/tomcat/bin/startup.sh
关闭命令为       /usr/local/tomcat/bin/shutdown.sh

三、配置nginx

vim /usr/local/lnmp/nginx/conf/nginx.conf
--> http {
upstream westos {
sticky;
server 172.25.50.1:8080;
server 172.25.50.2:8080;
}
location ～ \.jsp$ {
proxy_pass http://westos; }

最后也可以自写测试页

vim /usr/local/tomcat/webapps/ROOT/test.jsp

<%@ 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>");%>
<%
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>");
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="test.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>
