There are 3 backend servers, 2 servers run one Tomcat on standard ports and 1 server runs two Tomcat on different ports (see file workers.porperties).
For the log file, I have only 1 log file for all the workers defined in mod_jk.conf by the following line :
# Where to put jk logs JkLogFile logs/mod_jk.log
So I don't have any info about the other workers.
If you are talking about the other tomcat, I can access them directly via their IP and port with a browser on the LAN. So I can say all the tomcat servers are up and running.
The strange thing is that this setup works fine with mod_JK2. But I would like to have a setup with JK1 since JK2 is not supported anymore.
Regards,
Christophe

Are the Tomcat instance running on the same physical server and you are just using IP Aliases, or are the workers running on 3 sperate backend machines?
You apache config looks OK, so I don't believe its an issue with Apache Virtual Host configuration. I believe all work in being forwarded to Demo1 only.
I believe you can have multiple instances of tomcat listening on the
same port by specifying an IP address in the connector. But I find it
much easier just to congigure each instance to listen on a different
port.
If you check your other 2 workers log files, you will probably see an
error similar to "Bind address already in use".
Modify each Tomcat instance to the SHUTDOWN and AJP listener are each on
unique ports;
For example, In each respective instance server.xml use;
Demo1 Shutdown: 8001 Demo1 HTTP: 8081 Demo1 AJP Listener: 8101
Demo2 Shutdown: 8002 Demo2 HTTP: 8082 Demo2 AJP Listeer: 8102
Demo3 Shutdown: 8003 Demo3 HTTP: 8083 Demo3 AJP Listern: 8103
Restart each instance (check the catalina.out for errors)
Modify your workers.properties file to relect the new AJP listen ports
Restart Apache

If you are running multiple instances of Tomcat, from what I understand and from my configuration (i run two Tomcat/mod_jk2 with Apache) you would then need each of them to listen on a different port. Right now the only instance that will receive requests via the worker is the instance that is using port 8009.

would it be the fact that your sending the requests through the same port number?

Hello,
I would like to setup a Apache 2.0.53 as front-end for several Tomcat
5.0.19. I use JK1.2.8 as connector.
I have defined one worker per tomcat server. I use three name based virtual hosts in the apache config.
The problem is only the first virtual host works. In the mod_jk.log, I can see that every request sent to the apache are checked with the JkMount from the first virtual host only.
Here are my config files :
-------------------- workers.properties ----------------------- worker.list=demo1,demo2,demo3,stat
worker.demo1.type=ajp13 worker.demo1.host=192.168.0.1 worker.demo1.port=8009
worker.demo2.type=ajp13 worker.demo2.host=192.168.0.2 worker.demo2.port=8009
worker.demo3.type=ajp13 worker.demo3.host=192.168.0.3 worker.demo3.port=8009
worker.stat.type=ajp13 worker.stat.host=192.168.0.3 worker.stat.port=7201 ----------------- end of workers.properties -------------------
In the httpd.conf file, I include the file mod_jk.conf (no other virtual hosts are defined in httpd.conf):
-------------------- mod_jk.conf ----------------------- # Load mod_jk module LoadModule jk_module modules/mod_jk.so
# Where to find workers.properties JkWorkersFile conf/workers.properties
# Where to put jk logs JkLogFile logs/mod_jk.log
# Set the jk log level [debug/error/info] JkLogLevel debug
# Select the log format JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
# JkRequestLogFormat set the request format JkRequestLogFormat "%w %V
'/'%T"
NameVirtualHost *:81
<VirtualHost *:81> ServerName demo1.myweb.org JkMount /*/tracking/* stat JkMount /tracking/* stat JkMount /web/* demo1 JkMount /ald/* demo1 JkMount /htmleditor/* demo1 JkMount /* demo1 </VirtualHost>
<VirtualHost *:81> ServerName demo2.myweb.org JkMount /*/tracking/* stat JkMount /* demo2 </VirtualHost>
<VirtualHost *:81> ServerName demo3.myweb.org JkMount /*/tracking/* stat JkMount /* demo3 </VirtualHost> ----------------- end of mod_jk.conf -------------------

But I get the homepage of demo1.myweb.org...
Any idea why this happen?
