System environment: Windows XP SP3, jdk1.6.0 _ 13

Software version: httpd-2.2.21-win32-x86-openssl-0.9.8r.msi apache-tomcat-6.0.33 tomcat-connectors-1.2.32-windows-i386-

 

 

Httpd-2.2.x

 

 

I did a test on a machine, because I have completed apache server load balancer and replica of Tomcat 6 clusters and sessions,

You may need to modify the configuration as follows:

 

 

1. modify httpd. conf of apache:

 

 

First, load the required so file and remove the comments before the following lines.

LoadModule proxy_module modules/mod_proxy.so

LoadModule proxy_ajp_module modules/mod_proxy_ajp.so

LoadModule proxy_balancer_module modules/mod_proxy_balancer.so

LoadModule proxy_connect_module modules/mod_proxy_connect.so

LoadModule proxy_ftp_module modules/mod_proxy_ftp.so

 

 

Add the load connector configuration

LoadModule jk_module modules/mod_jk.so

JkWorkersFile "conf \ workers. properties"

JkMount/*. jsp controller

 

 

Remove comments from VM

Include conf/extra/httpd-vhosts.conf

 

 

Add server load balancer configuration at the end

 

 

SetHandler server-status

Order Deny, Allow

Deny from all

Allow from all

SetHandler balancer-manager

Order Deny, Allow

Deny from all

Allow from all

ProxyRequests Off

ProxyPass/test balancer: // tomcatcluster/stickysession = jsessionid nofailover = On

 

 

 

 

BalancerMember ajp: // 127.0.0.1: 8009 loadfactor = 1 route = route 1

BalancerMember ajp: // 127.0.0.1: 9009 loadfactor = 1 route = tomcat2

 

 

 

2. add the following to the apache httpd-vhosts.conf file:

 

 

 

 

ServerAdmin webmaster@163.com

ServerName localhost

ServerAlias localhost

ProxyPass/balancer: // tomcatcluster/stickysession = jsessionid nofailover = On

ProxyPassReverse/balancer: // tomcatcluster/

 

 

3. create the workers. properties file

 

 

#========= Export AT1 ========

Worker. tomcat1.port = 8009 # ajp13 port number, which is configured in server. xml under tomcat. the default value is 8009.

Worker. tomcat1.host = localhost # tomcat host address. if not, enter the IP address

Worker. tomcat1.type = ajp13

Worker. tomcat1.lbfactor = 1 # server weighting ratio. the higher the value, the more requests are allocated.

 

#======= Tomcat2 =========

Worker. tomcat2.port = 9009 # ajp13 port number, which is configured in server. xml under tomcat,

Worker. tomcat2.host = localhost # tomcat host address. if not, enter the IP address

Worker. tomcat2.type = ajp13

Worker. tomcat2.lbfactor = 1 # server weighting ratio. the higher the value, the more requests are allocated.

#======= Controller, server load balancer controller ========

Worker. controller. type = lb

Worker. controller. balanced_workers = worker AT1, tomcat2 # specify tomcat that shares the request

Worker. controller. sticky_session = false # worker. controller. sticky_session = 1

 

 

4. modify tomcat server. xml:

 

In addition to changing both tomcat conflicting ports, you also need to add the cluster settings.

 

 

 

 

-- The other is Tomcat 2.

 

 

ExpireSessionsOnShutdown = "false"

NotifyListenersOnReplication = "true"/>

 

 

Address = "228.0.0.4"

Port = "45564"

Frequency = "500"

DropTime = "3000" type = "codeph" text = "codeph"/>

Address = "auto"

Port = "5001"

SelectorTimeout = "100"

MaxThreads = "6"/>

Filter = ". *\. gif ;. *\. js ;. *\. jpg ;. *\. png ;. *\. htm ;. *\. html ;. *\. css ;. *\. txt; "/>

TempDir = "/tmp/war-temp /"

DeployDir = "/tmp/war-deploy /"

WatchDir = "/tmp/war-listen /"

WatchEnabled = "false"/>

 

 

 

 

5. configure web. xml in the webapps

 

 

 

 

You must add

This application will copy the Session with the cluster server

 

 

After the configuration is complete, start all tomcat servers and then start the apache2.2 server.

 

 

6. the following jsp can be deployed as a test program in tomcat1, tomcat2

<% @ Page contentType = "text/html; charset = GBK" %>

<% @ Page import = "java. util. *" %>

Cluster App Test

Server Info:

<%

Out. println (request. getLocalAddr () + ":" + request. getLocalPort () +"
"); %>

<%

Out. println ("
ID "+ session. getId () +"
");

String dataName = request. getParameter ("dataName ");

 

If (dataName! = Null & dataName. length ()> 0 ){

String dataValue = request. getParameter ("dataValue ");

Session. setAttribute (dataName, dataValue );

}

 

Out. print ("Session List");

 

Enumeration e = session. getAttributeNames ();

 

While (e. hasMoreElements ()){

String name = (String) e. nextElement ();

String value = session. getAttribute (name). toString ();

Out. println (name + "=" + value +"
");

System. out. println (name + "=" + value );

}

%>

 

 

After successful configuration, the result is 2017at1. the session content is the same in the background of Tomcat 2 and is distributed through apache access requests.

 

From my complaint
