nginx+tomcat+memcached实现交叉存储

打开nginx和php

nginx
/etc/init.d/php-fpm strat

官网上下载jdk，解压，并配置文件

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

source /etc/profile
echo $PATH
echo $CLASSPATH
echo $JAVA_HOME

测试：

vim test.java
public class test
{
        public static void main(String[] args)
        {
                System.out.println("hello word");
        }
}
javac test.java
java test

官网上下载apache-tomcat-7.0.37.tar.gz

tar zxf apache-tomcat-7.0.37.tar.gz -C /usr/local
cd /usr/local/
ln -s apache-tomcat-7.0.37/ tomcat
bin/startup.sh # 开启tomcat

这里写图片描述

cd logs/catalina.out #日志
cd /usr/local/tomcat/webapps/ROOT

浏览器验证tomcat服务：

vim vim test.jsp
The time is : <%new = %>

cd /usr/local/lnmp/nginx/conf/
vim nginx.conf
http {

        upstream tomcat{
        sticky;
        server 172.25.11.6:8080;
        server 172.25.11.7:8080;
        }

        location ~ \.jsp$ {
            proxy_pass   http://127.0.0.1;
        }
nginx -s reload

浏览器中验证：172.25.11.7:8080

scp jdk-7u79-linux-x64.tar.gz apache-tomcat-7.0.37.tar.gz server6:
在server6中做相同的配置，
scp test.jsp server6:/usr/local/tomcat/webapps/ROOT

vim 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>

浏览器测试：
172.25.11.7/test.jsp
在链接之后，一次之后就会跳转到下一个连接上。

vim /usr/local/tomcat/conf/context.xml
<Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"
memcachedNodes="n1:192.168.0.91:11211,n2:192.168.0.92:11211"
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"
/>
