Subject Re: apache + mod_jk + two tomcat instance configuration
Date Sun, 01 Jun 2008 00:58:46 GMT
Hi John,

Thanks for the comments. I did what you told me, but it does not work. here
is what I did:

workers.properties:

workers.java_home=/usr/lib/jdk1.6.0_04
#List workers
worker.list=worker001,worker002
#Define worker001
worker.worker001.port=8009
worker.worker001.host=localhost
worker.worker001.type=ajp13
worker.worker001.lbfactor=1

#Define worker002
worker.worder002.port=8010
worder.worker002.host=localhost
worker.worker002.type=ajp13
worker.worker002.lbfactor=1

httpd.conf:

LoadModule jk_module modules/mod_jk.so
# Where to find workers.properties
JkWorkersFile /etc/httpd/conf/workers.properties
# Where to put jk logs
JkLogFile /etc/httpd/logs/mod_jk.log
# Set the jk log level [debug/error/info]
JkLogLevel warn
# Select the log format
JkLogStampFormat "[%a %b %d %H:%M:%S %Y]"

virtual hosts:
##### for www.domain1.com -- by tomcat6.0.16
<VirtualHost *:80>
   ServerAdmin admin@domain1.com
   DocumentRoot /usr/servers/apache-tomcat-6.0.16/webapps/www.domain1.com
   ServerName www.domain1.com
   ErrorLog logs/domain1_error_log
   JkMount /*.jsp worker001
   JkMount /*.do worker001
</VirtualHost>
##### for cb.domain1.com  -- by codebeamer's built in tomcat
<VirtualHost *:80>
   ServerAdmin admin@domain1.com
   DocumentRoot /home/codebeamer/cb4/tomcat/webapps/cb
   ServerName cb.domain1.com
   ErrorLog logs/cb_error_log
   JkMount /*.* worker002
   JkMount /cb/*.* worker002
</VirtualHost>

I have changed AJP1.3 connector's port from 8009 to 8010 in codebeamer's
tomcat server.xml (worker002)

Now, all my PHP applications works correctly from internet by enter their
corresponding URL.
The Java application can be accessed too by www.domain1.com

but cb.domain1.com goes to the Java application under
www.domain1.cominstead of codebeamer, I checked access logs,
cb.domain1.com still forward request to tomcat6.0.16 by worker001.
cb.domain1.com is a subdomain of www.domain1.com.

Any idea why is this?

Thanks again.

Jiansen
