RE: Apache+Tomcat + MOD_JK on different machine
Hi Randall, I WOULD LIKE TO THANK YOU. My Apache and Tomcat on different machine are working great now. THANK YOU AGAIN for your time and input.

RE: Apache+Tomcat + MOD_JK on different machine
From what I can see, it should work. So you can browse http://someserver:8080/examples on the server where Tomcat is installed, right? Also, there just to be on the safe side, your network allows communication from one machine to another on port 8009. Try using telnet to access the server running tomcat from a seperate computer to see if the port is even accessible. Or if you have nmap, scan the tomcat box to see what ports are open or accessible. I performed a similar setup on a couple of test servers and it worked. One machine was running apache on linux and the other was running tomcat on windows. I am running out of things to tell ya. Anyone else want to take a stab at this??? Of course looking at your logs more closely, these lines here would assume that you are connecting the examples context??

Apache+Tomcat + MOD_JK on different machine
SUBJECT: Apache+Tomcat + MOD_JK on different machine I am using Apache 2.0.47 and Tomcat 4.1.27 on my SuSE Linux. I had configured my mod_jk and it works just great! (My Web and App Server were on same box) Now I have a Web Server and App Server on a different box and was wondering what changes do I have to make to MOD_JK for the Integration to work. My old settings were: -- httpd.conf -- LoadModule jk_module modules/mod_jk.so ServerName abc.com Include /usr/local/tomcat4/conf/auto/mod_jk.conf JkWorkersFile /usr/local/apa2047/conf/workers.properties JkLogFile /usr/local/apa2047/logs/mod_jk.log JkLogLevel debug JkMount /examples ajp13 JkMount /examples/* ajp13 workers.properties workers.CATALINA_HOME=/usr/local/tomcat4 workers.java_home=$(JAVA_HOME) ps=/ worker.list=ajp13 worker.ajp13.port=8009 worker.ajp13.host=101.102.103.104 #above is IP address of abc.com worker.ajp13.type=ajp13 worker.ajp13.lbfactor=5 Now that I have both APACHE and TOMCAT on DIFFERENT Boxes, I was wondering what changes do I have to make for the above to work.

Your workers.properties should be on your webserver where apache is located. I typically place the workers.properties in the same directory where httpd.conf is located. workers.properties is needed for mod_jk so it makes sense that it needs to be in the same machine where mod_jk and apache are installed. At least far as I know anyways. Sometimes apache has a difficult time finding it. I have used this line to tell apache where to find the workers.properties.

I would also confirm in you logs that everything is working ok. However, Apache should not even startup if the included configuration file, mod_jk.conf is not present. -- httpd.conf (on Web Server) -- LoadModule jk_module modules/mod_jk.so ServerName xyz.com Include conf/mod_jk.conf JkWorkersFile conf/workers.properties JkLogFile logs/mod_jk.log JkLogLevel debug JkMount /examples ajp13 JkMount /examples/* ajp13 The trick here is to make some changes to your workers.properties in order to connect to another box. It looks as if your are trying to configure a load balancer. If you are connecting to only one instance of tomcat this is not necessary. Also you need to look in your server.xml and see that you have the coyote connector running on port 8009. I would exclude the line: worker.ajp13.lbfactor=5 from this configuration. Besides, you have not defined a worker for load balancer, so i believe this line is not necessary. I would probably write your workers.properties files the following way: workers.properties (on Web Server

Hmmm...I did not even configure any virtual hosts, although I know you can but I rarely do for my implementations.

SUBJECT: Apache+Tomcat + MOD_JK on different machine I am using Apache 2.0.47 and Tomcat 4.1.27 on my SuSE Linux. I had configured my mod_jk and it works just great! (My Web and App Server were on same box) Now I have a Web Server and App Server on a different box and was wondering what changes do I have to make to MOD_JK for the Integration to work. My old settings were: -- httpd.conf -- LoadModule jk_module modules/mod_jk.so ServerName abc.com Include /usr/local/tomcat4/conf/auto/mod_jk.conf JkWorkersFile /usr/local/apa2047/conf/workers.properties JkLogFile /usr/local/apa2047/logs/mod_jk.log JkLogLevel debug JkMount /examples ajp13 JkMount /examples/* ajp13 workers.properties workers.CATALINA_HOME=/usr/local/tomcat4 workers.java_home=$(JAVA_HOME) ps=/ worker.list=ajp13 worker.ajp13.port=8009 worker.ajp13.host=101.102.103.104 #above is IP address of abc.com worker.ajp13.type=ajp13 worker.ajp13.lbfactor=5 Now that I have both APACHE and TOMCAT on DIFFERENT Boxes, I was wondering what changes do I have to make for the above to work.
