• Apache2.2 Tomcat7 集群 session共享 [windows]


    Apache2.2  Tomcat7 集群 session共享

    下载:

    Apache2.2、apache-tomcat-7.0.42.zip、tomcat-connectors-1.2.37-windows-i386-httpd-2.2.x.zip【mod_jk】

    分别解压缩Apache2.2、apache-tomcat-7.0.42.zip、tomcat-connectors-1.2.37-windows-i386-httpd-2.2.x.zip

    此处:C:Apache2.2、C: omcat omcat71、C: omcat omcat72

    copy从comcat-connectors-1.2.37-windows-i386-httpd-2.2.x.zip解压缩后的文件mod_jk.so至C:Apache2.2modules中。

    在C:Apache2.2conf下新建文件workers.properties、内容如下:

    #server 列表
    worker.list = controller,tomcat1,tomcat2 
    
    #========tomcat1========
    worker.tomcat1.port=8009 #注意这是 ajp1.3 端口号,在tomcat下server.xml配置,默认8009。不是tomcat的web端口
    worker.tomcat1.host=localhost #tomcat的主机地址,如不为本机,请填写ip地址
    worker.tomcat1.type=ajp13
    worker.tomcat1.lbfactor = 1   #server的加权比重,值越高,分得的请求越多
    
    #========tomcat2========
    worker.tomcat2.port=9009
    worker.tomcat2.host=localhost
    worker.tomcat2.type=ajp13
    worker.tomcat2.lbfactor = 1
    
    
    #========controller,负载均衡控制器========
    worker.controller.type=lb
    worker.controller.balanced_workers=tomcat1,tomcat2  #指定分担请求的tomcat
    
    #session复制模式
    worker.controller.sticky_session=false
    worker.controller.sticky_session_force=1
    
    #sticky模式,即黏性会话模式
    #worker.controller.sticky_session=1 

    在C:Apache2.2conf下新建文件mod_jk.conf、内容如下:

    #加载mod_jk Module
    LoadModule jk_module modules/mod_jk.so
    
    #指定 workers.properties文件路径
    JkWorkersFile conf/workers.properties
    
    #指定那些请求交给tomcat处理,"controller"为在workers.propertise里指定的负载分配控制器名
    JkMount /*.jsp controller

    修改C:Apache2.2confhttpd.conf,在最后一行,添加:

    include "C:Apache2.2confmod_jk.conf"

    此时,apache修改完毕;

    接下来修改tomcat、修改tomcat1的C: omcat omcat71confserver.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的端口避免有冲突。

    创建test文件夹,在其下新建test.jsp,内容如下:

    <%@ 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>

    将test文件夹分别copy至C: omcat omcat71webapps、C: omcat omcat72webapps下。

    分别启动或重启tomcat1、tomcat2、apache、无先后顺序。

    浏览器输入:

    http://localhost/test/test.jsp

    观察效果。

    Done.
