Subject Re: Tomcat6 with mod_jk
Date Sun, 09 Jan 2011 01:28:12 GMT
Hello,

What I am trying unsuccessfully to do is - on debian (lenny) with apache2 have multiple instances
of 
tomcat6 each servicing a different domain using a java war/servlet

To date I have only loaded one domain "appledorera.org"

file /etc/apache2/mods-enabled/jk.load is
  LoadModule jk_module /usr/lib/apache2/modules/mod_jk.so

file  /etc/apache2/sites-enabled/appledorera.org is
<VirtualHost appledorera.org:80>
         ServerAdmin admin@appledorera.org
         ServerName  appledorera.org
         ServerAlias www.appledorera.org
         JkMount /* appledorera
</VirtualHost>

file /etc/apache2/workers.properties is
workers.tomcat_home = /usr/local/tomcat
workers.java_home=  / usr/lib/jvm/java-6-sun
ps = /
worker.list=appledorera
  Set properties for appledorera
worker.appledorera.type=ajp13
worker.appledorera.host=localhost
worker.appledorera.port=8109

file /etc/apache2/conf.d/jk.conf is
<IfModule mod_jk.c>
     JkWorkersFile /etc/apache2/workers.properties
     JkLogFile /var/log/apache2/mod_jk.log
     JkLogLevel debug
</ifmodule>

file /usr/local/tomcat/instances/appledorera/conf/server.xml I have amended
<Server port="8005" shutdown="SHUTDOWN">  to
<Server port="8105" shutdown="SHUTDOWN">
and
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" /> to
<Connector port="8109" protocol="AJP/1.3" redirectPort="8443" />

When the tomcat instance in /usr/local/tomcat/instances/appledorera is stopped
http://appledorera.org/  gives Service Temporarily Unavailable
and tail /var/log/apache2/mod_jk.log is
