切换到幻灯片模式
需要配置前端web层和后端应用层: 
1.web层配置: 
<!--
            - Configuration 
for the web-tier/load-balancer
            -->
            <cluster id=
"web-tier">
            <server-default>
            <!-- The http port -->
            <http address=
"*" port=
"80"/>
            </server-default>
             
            <server id=
"web-a" address=
"127.0.0.1" port=
"6700"/>
             
            <cache path=
"cache" memory-size=
"64M"/>
             
            <host id=
"">
            <web-app id=
"/">
             
            <rewrite-dispatch>
            <load-balance regexp=
"" cluster=
"app-tier"/>
            </rewrite-dispatch>
             
            </web-app>
            </host>
            </cluster>
             
            <cluster id=
"app-tier">
            <server id=
"a" address=
"127.0.0.1" port=
"6800"/>
            <server id=
"b" address=
"127.0.0.1" port=
"6801"/>
             
            <persistent-store type=
"cluster">
            <init path=
"cluster"/>
            </persistent-store>
             
            <web-app-default>
            <session-config>
            <use-persistent-store/>
            </session-config>
            </web-app-default>
             
            <host id=
"">
            ...
            </host>
            </cluster>
           
以上配置将来自80的请求分发给app-tier应用层集群处理。 
2.应用层集群配置: 
    <!-- define the servers in the cluster -->
<server id="a" address="127.0.0.1" port="6800"/>
<server id="b" address="127.0.0.1" port="6801"/>
3.启动应用层服务器: 
D:\resin-pro-3.1.3\httpd.exe -conf conf/resin1.conf -server a
 D:\resin-pro-3.1.3\httpd.exe -conf conf/resin1.conf -server b
以上启动了两个应用服务器a和b. 
4.启动前端WEB服务器: 
    
        
            | 1
 | > D:\resin-pro-3.1.3\httpd.exe -conf conf/resin-web.conf -server web-a
             | 
    
5.写测试JSP a.jsp: 
    
        
            | 1
 | <%System.out.println("aaaaaaaaaaaa");%>
             | 
    
6.在浏览器中访问: 
http://localhost/a.jsp 
观察一下控制台,会在两个窗口控制台轮流打印出 aaaaaaaaaaaa,说明负载均衡Servlet工作正常。 
关掉一个应用服务器,再次访问,会发现访问正常。
