Apache2.2 TOMCAT7 Cluster session sharing
Download:
Apache2.2, Apache-tomcat-7.0.42.zip, tomcat-connectors-1.2.37-windows-i386-httpd-2.2.x.zip "MOD_JK"
Decompress Apache2.2, Apache-tomcat-7.0.42.zip, Tomcat-connectors-1.2.37-windows-i386-httpd-2.2.x.zip respectively
Here: C:\Apache2.2, C:\tomcat\tomcat71, C:\tomcat\tomcat72
Copy the extracted files from Comcat-connectors-1.2.37-windows-i386-httpd-2.2.x.zip mod_jk.so to C:\Apache2.2\modules.
Under C:\Apache2.2\conf, create a new file workers.properties with the following content:
#server list worker.list = controller,tomcat1,tomcat2 #========tomcat1========worker.tomcat1.port=8009 #注意这是 ajp1.3 port number, Under Tomcat server.xml configuration, default 8009. Not tomcat Web Port Worker.tomcat1.host=localhost #tomcat的主机地址, if not native, please fill in the IP address worker.tomcat1.type= Ajp13worker.tomcat1.lbfactor = 1 #server的加权比重, the higher the value, the more requests to be divided #========tomcat2========worker.tomcat2.port= 9009worker.tomcat2.host=localhostworker.tomcat2.type=ajp13worker.tomcat2.lbfactor = 1#========controller, Load balancer Controller ========worker.controller.type=lbworker.controller.balanced_workers=tomcat1,tomcat2
Under C:\Apache2.2\conf, create a new file mod_jk.conf with the following content:
#加载mod_jk moduleloadmodule jk_module modules/mod_jk.so# Specify workers.properties file path Jkworkersfile conf/ workers.properties# Specifies that those requests be given to Tomcat processing, "controller" for the load assignment controller name specified in Workers.propertise jkmount/*.jsp Controller
Modify C:\Apache2.2\conf\httpd.conf, in the last line, add:
Include "C:\Apache2.2\conf\mod_jk.conf"
At this point, Apache modification is complete;
Next modify Tomcat, modify TOMCAT1 's C:\tomcat\tomcat71\conf\server.xml
<name= "Catalina" defaulthost= "localhost" jvmroute = "TOMCAT1" > ... < className= "Org.apache.catalina.ha.tcp.SimpleTcpCluster"/>
Modify TOMCAT2 's Server.xml file
<ServerPort= "9005"shutdown= "SHUTDOWN">..... <ConnectorPort= "9090"Protocol= "http/1.1"ConnectionTimeout= "20000"Redirectport= "8443" />..... <ConnectorPort= "9009"Protocol= "ajp/1.3"Redirectport= "8443" />..... <Enginename= "Catalina"Defaulthost= "localhost"Jvmroute= "Tomcat2">..... <ClusterClassName= "Org.apache.catalina.ha.tcp.SimpleTcpCluster"/>
The main is to modify the port, so that it with the TOMCAT1 port to avoid conflict.
Create the Test folder, under which you created a new test.jsp, with the following content:
<%@ 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 haveNewSession attrSet StringDataname=Request.getparameter ("Dataname"); if(dataname! )= NULL &&dataname.length ()> 0) { StringDataValue=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 ()) {Stringname= (String) e.nextelement (); Stringvalue=Session.getattribute (name). toString (); OUT.PRINTLN (Name+ " = " +value+ "<br>"); SYSTEM.OUT.PRINTLN (Name+ " = " +value); } %> <formAction= "test.jsp"Method= "POST">Name:<inputtype=textsize=20name= "Dataname"> <BR>Value:<inputtype=textsize=20name= "DataValue"> <BR> <inputtype=submit> </form></Body></HTML>
Copy the test folder to C:\tomcat\tomcat71\webapps, C:\tomcat\tomcat72\webapps, respectively.
Start or restart TOMCAT1, TOMCAT2, Apache, and no order respectively.
Browser input:
http://localhost/test/test.jsp
Observe the effect.
Done.
