Apache2.2 Tomcat7 集羣 session共享html

下載：java

Apache2.二、apache-tomcat-7.0.42.zip、tomcat-connectors-1.2.37-windows-i386-httpd-2.2.x.zip【mod_jk】web

分別解壓縮Apache2.二、apache-tomcat-7.0.42.zip、tomcat-connectors-1.2.37-windows-i386-httpd-2.2.x.zipapache

此處：C:\Apache2.二、C:\tomcat\tomcat7一、C:\tomcat\tomcat72windows

copy從comcat-connectors-1.2.37-windows-i386-httpd-2.2.x.zip解壓縮後的文件mod_jk.so至C:\Apache2.2\modules中。瀏覽器

在C:\Apache2.2\conf下新建文件workers.properties、內容以下：tomcat

#server 列表
worker.list = controller,tomcat1,tomcat2 

#========tomcat1========
worker.tomcat1.port=8009 #注意這是 ajp1.3 端口號，在tomcat下server.xml配置,默認8009。不是tomcat的web端口
worker.tomcat1.host=localhost #tomcat的主機地址，如不爲本機，請填寫ip地址
worker.tomcat1.type=ajp13
worker.tomcat1.lbfactor = 1   #server的加權比重，值越高，分得的請求越多

#========tomcat2========
worker.tomcat2.port=9009
worker.tomcat2.host=localhost
worker.tomcat2.type=ajp13
worker.tomcat2.lbfactor = 1


#========controller,負載均衡控制器========
worker.controller.type=lb
worker.controller.balanced_workers=tomcat1,tomcat2  #指定分擔請求的tomcat

#session複製模式
worker.controller.sticky_session=false
worker.controller.sticky_session_force=1

#sticky模式，即黏性會話模式
#worker.controller.sticky_session=1

在C:\Apache2.2\conf下新建文件mod_jk.conf、內容以下：session

#加載mod_jk Module
LoadModule jk_module modules/mod_jk.so

#指定 workers.properties文件路徑
JkWorkersFile conf/workers.properties

#指定那些請求交給tomcat處理,"controller"爲在workers.propertise裏指定的負載分配控制器名
JkMount /*.jsp controller

修改C:\Apache2.2\conf\httpd.conf，在最後一行，添加：app

include "C:\Apache2.2\conf\mod_jk.conf"

此時，apache修改完畢；負載均衡

接下來修改tomcat、修改tomcat1的C:\tomcat\tomcat71\conf\server.xml

    <Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat1">
...
      <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>

修改tomcat2的server.xml文件

<Server port="9005" shutdown="SHUTDOWN">
。。。
    <Connector port="9090" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
。。。
    <Connector port="9009" protocol="AJP/1.3" redirectPort="8443" />
。。。
    <Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat2">
。。。
      <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>

主要是修改端口，使其同tomcat1的端口避免有衝突。

建立test文件夾，在其下新建test.jsp,內容以下：

<%@ 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>");
        // if have new Session attr set
        String dataName = request.getParameter("dataName");
        if (dataName != null && dataName.length() > 0) {
            String dataValue = request.getParameter("dataValue");
            session.setAttribute(dataName, dataValue);
        }
        out.println("<b>Session list</b><br>");
        System.out.println("=============tomcat 1===============");

        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>
        value:<input type=text size=20 name="dataValue"> <br> <input
            type=submit>
    </form>
</body>
</html>
