View Full Version : [ubuntu] Tomcat and Apache

April 23rd, 2008, 08:40 PM
I would like to set up tomcat and apache on an Ubuntu server. I want to set it up so that www.mydomain.com hits my webapp (hosted by tomcat) directly. I am a completely newbie webadmin, so I am not sure where to start.

I am also open to using tomcat on it's own (without apache), but I don't want ":8080/mywebapp" showing up on the address bar...

I found a few tutorials but they all seemed pretty outdated

You need a Tomcat Connector. Here is another guide for you: http://aeronetworks.ca/tomcat-howto.html

Hey daveklein,

to elaborate on HermanAB's response, here is a link from another poster a few months ago.


I've been battling this setup for a few days myself and have yet to find the answer.

My first step is just to get Tomcat going through Apache, so http://localhost/servlet actually hits my Tomcat server.

I manually installed Tomcat6, downloaded the mod_jk binary myself, and followed all of the Apache documentation, to no avail. Here's the Apache link:

If you have success at all, do you mind posting back? I'll do the same if I get this working. I plan on going back to battle this evening.

I'll check out the links you gave me. And yes, I'll be sure to post here if I get it to work.

Hi Dave, I think I've got it working.

I couldn't use the auto-generated mod-jk.conf from Tomcat, so I created a static one. Follow these steps and let me know how it goes.

If you've not already done so, install the libmod-jk library using your Package Manager.
You should now have a file mod_jk.so installed (mine is at /usr/lib/apache2/modules)

Below is my configuration file for mod-jk (located at $TOMCAT_INSTALL/conf/jk/mod-jk.conf)

# Load mod_jk module
# Update this path to match your modules location
# Leave this commented out too. It's already loaded somehow
# and this throws a warning
#LoadModule jk_module /usr/lib/apache2/modules/mod_jk.so

# Where to find workers.properties
JkWorkersFile $TOMCAT_INSTALL/conf/jk/workers.properties

# Where to put jk shared memory
JkShmFile /var/log/apache2/mod_jk.shm

# Where to put jk logs
JkLogFile /var/log/apache2/mod_jk.log

# Set the jk log level [debug/error/info]
JkLogLevel info

# Select the timestamp log format
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "

Now here is the line I added to my apache2.conf file

#For Tomcat
Include /opt/tomcat/conf/jk/mod-jk.conf

Lastly, I created a file as Apache suggested to restart my apps in the right order:


apache2ctl -k stop
apache2ctl -k start

I hit http://localhost/examples/servlets and it worked!

NOTE: Don't forget to replace $TOMCAT_INSTALL with your install path. Don't try to create an environment variable named TOMCAT_INSTALL.

Good luck!

You should be able to setup Tomcat as a stand-alone server running on port 80. However, if you are looking to use Apache as a front-end and have it proxy requests to Tomcat, that is the same setup that I have used.

We originally set this up on Windows, but have since migrated over to Ubuntu and have been much happier. We have a tutorial written on our blog if you are interested:
