mod_jk

[monkeynuts84]

Hi,
   I'm having problems getting mod_jk to work. I've moved the html files to the apache webroot. When I set up mod_jk and start tomcat the site can't seem to find the search.jsp. Does anyone have a working example config for mod_jk that I can cross reference with mine?

Thanks in advance.

Here is sample (also my production copy) and I hope it helps you out a bit;
 
mod_jk.conf:
 
# Replace jsp-hostname with the hostname of your JSP server, as
# specified in workers.properties.
#
<IfModule mod_jk.c>
        JkWorkersFile etc/apache/workers.properties
        JkLogFile  /var/log/jk.log
        JkShmFile  /var/log/jk-runtime-status
        JkLogLevel error
        # Sample JkMounts.  Replace these with the paths you would
        # like to mount from your JSP server.
        #JkMount /*.jsp jsp-hostname
        #JkMount /servlet/* jsp-hostname
        #JkMount /examples/* jsp-hostname
</IfModule>

 
workers.properties:
 
# Incredibly simple workers.properties file, intended for connecting
# to one host, via AJP13.  See the tomcat documentation for
# information on more exotic configuration options.
#
# Change jsp-hostname to the hostname of your JSP server.
#
worker.list=link
worker.link.port=8009
worker.link.host=link.enhancededge.com
worker.link.type=ajp13
worker.link.lbfactor=1

 
httpd.conf (in the appropriate area):
 
<VirtualHost 216.58.87.200>
    DocumentRoot /usr/local/www/data/results.bigsearch.ca/
    ServerName results.bigsearch.ca
    JkMount /* link
    CustomLog /var/log/httpd/results.bigsearch.ca.log combined
</VirtualHost>

What kind of error page do you get: one from Tomcat or one from Apache?

Hal,
    The error is from apache. It can't seem to find the jsp files. Is there something specific I need to do in the config file regarding the nutch jsp location?

Thanks.

In my setup, I do not have nutch installed in the tomcat root, instead
it is in /search. IIRC, without doing some additional fiddling, both
apache and tomcat must agree on the path to the web application. In my
case, that means that both Apache and Tomcat must believe that the
webapp is in /search. For that kind of setup, I have the following in my
Apache config:

LoadModule      jk_module modules/mod_jk.so
JkWorkersFile   /etc/httpd/conf/workers.properties
JkLogFile       logs/mod_jk.log
JkLogLevel      error
JkMount /search ajp13
JkMount /search/* ajp13

note that both JkMount lines are necessary if you want Tomcat to see
requests for /search without the trailing slash.

The workers.properties has:
workers.tomcat_home=/usr/share/tomcat5
workers.java_home=/usr/java/default
ps=/
worker.list=ajp12, ajp13, jboss
worker.ajp13.port=8009
worker.ajp13.host=localhost
worker.ajp13.type=ajp13
worker.ajp13.lbfactor=1
worker.loadbalancer.type=lb
worker.loadbalancer.balance_workers=ajp13
worker.inprocess.type=jni
worker.inprocess.class_path=$(workers.tomcat_home)$(ps)lib$(ps)tomcat.jar
worker.inprocess.cmd_line=start
worker.inprocess.jvm_lib=$(workers.java_home)$(ps)jre$(ps)lib$(ps)i386$(ps)server$(ps)libjvm.so
worker.inprocess.stdout=$(workers.tomcat_home)$(ps)logs$(ps)inprocess.stdout
worker.inprocess.stderr=$(workers.tomcat_home)$(ps)logs$(ps)inprocess.stderr

Then, make sure that Tomcat really is listening on port 8009 on the
loopback interface (localhost).

Just one more question (this may be where I'm going wrong!): the /search directory; is that relative to your tomcat install or is it the absolute path?

In my setup: /search is relative to the Tomcat webapps folder (from the
point of view of Apache, it is just an alias).

I see. That's probably where I've gone wrong. My nutch folders absolute path is /data.
