mod-jk stopped working
Apache 2.2 and Tomcat 6 on Linux Ubuntu 10.10
My connector worked fine for several years and then suddenly stopped
working! Now I get a "requested URL was not found on this server" error
instead. I've tried several things to fix this but no joy. Here is the
current content of my two files:
==============================
workers.properties file -->
workers.tomcat_home=/usr/share/tomcat6
workers.java_home=/usr/lib/jvm/java-6-openjdk/jre
ps=/
worker.list=ajp13_worker
worker.ajp13_worker.port=8009
worker.ajp13_worker.host=localhost
worker.ajp13_worker.type=ajp13
worker.ajp13_worker.lbfactor=1
worker.loadbalancer.type=lb
worker.loadbalancer.balance_workers=ajp13_worker
==============================
httpd.conf file -- >
LoadModule jk_module /usr/lib/apache2/modules/mod_jk.so
JkWorkersFile /etc/libapache2-mod-jk/workers.properties
JkShmFile /var/log/apache2/mod_jk.shM
JkLogFile /var/log/apache2/mod_jk.log
JkLogLevel info
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
JkMount /big41 ajp13_worker
JkMount /big41/* ajp13_worker
JkMount /big50 ajp13_worker
JkMount /big50/* ajp13_worker
JkMount /*.jsp ajp13_worker
JkMount /*/servlet/ ajp13_worker
==============================
I changed the JkLogLevel to debug, restarted Apache, and read through
the long log file. No errors and everything seems to have be setup
correctly. However, there was one strange occurrance. It went through
the entire setup process twice and gave me two of these log entries:
[info] init_jk::mod_jk.c (2830): mod_jk/1.2.26 initialized
[info] init_jk::mod_jk.c (2830): mod_jk/1.2.26 initialized
Now the log file is giving me a bunch of [debug] entries saying things
similar to: "missing uri map for
domU-12-31-39-04-58-57.compute-1.internal:/big41." Also, I have a bunch
of "missing uri map" entries for things present on the server that were
never JkMounted.
Like I said, it used to work fine. Any help or suggestions would be
greatly appreciated. Thank you!

Sounds like the mod_jk version and/or httpd was/were upgraded and you
didn't know. That's why a working configuration "suddenly" stopped
working.

Wow! I put my JkMounts inside the VirtualHost directives and now it is working again. Thank you very much!

This sounds like a missing JkMount in httpd or even a non-deployed
webapp in Tomcat. Can you tell which component it generating the page
(httpd versus Tomcat)?

Did you declare these JkMounts in a VirtualHost? Did you define them
at the top-level and then try to use them in a virtual host? If you do
a JkWorkersFile and JkMount at the top-level, they won't work within
virtual hosts. You have to either explicitly-add them to all virtual
hosts, or use JkMountCopy in each virtual host that should inherit the
configuration.
Maybe you added a new virtual host and forgot JkMountCopy? Or switched
from non-virtualhost configuration to one with a "default" virtual
host instead of none at all?
