How to connect Apache to Tomcat?

Felipe · 05-01-2011, 11:57 AM

Hallo:

I'm configuring a web server using Apache and Tomcat. I use Apache 2 and various instances of Tomcat5 and Tomcat6.
I try that Apache serves the static data and tomcat the dynamic (Apache receives all requests, sending tomcat only the dynamic)

I see that Apache and Tomcat can be connected using http or ajp Can any tell me:
- What connector should I use: ajp, http,...?
- How can I say Apache to serve the static data and Tomcat the dynamic?
Due to I have many instances of Tomcat, connectins http and https, https with client certificates, and due to the port configuration:
- Is there any way to configure Apache-tomcat without the use of ports in tomcat (a differect connector)?

An easy sample would be appreciated.

Thanks

I use mod_jk (ajp) to connect Apache and Tomcat. I made changes to the Apache httpd.conf file (you probably won't need the same set and there are others):

Code:

LoadModule jk_module modules/mod_jk.so
JkWorkersFile "/usr/local/apache2/conf/extra/workers.properties"
JkLogFile "/var/log/httpd/mod_jk.log"
JkLogLevel info
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
JkRequestLogFormat "%w %V %T

The workers.properties file contains this:

Code:

worker.list=ajp13
worker.ajp13.type=ajp13
worker.ajp13.host=localhost
worker.ajp13.port=8009
worker.ajp13.lbfactor=50
worker.ajp13.cachesize=10
worker.ajp13.cache_timeout=600
worker.ajp13.socket_keepalive=1
worker.ajp13.socket_timeout=300

To direct URLs I use this in the virtual hosts section:

Code:

  JkMount /timesheets ajp13
  JkMount /timesheets/* ajp13
  JkMount /timesheetadmin ajp13
  JkMount /timesheetadmin/* ajp13
  JkMount /testingdb ajp13
  JkMount /testingdb/* ajp13

This info is from an old backup (I'm not at work at the moment) and I can't recall why I have the top directory as well as the wildcard, but google may help.

Thank you for the information.
It's detailed and I'll look for some of the parameters.

The only question I can't see is how to say Apache to serve static data and Tomcat de dynamic.
Do I have to mount it on Apache and Tomcat? How do I do it?

Thanks

You can put the static URLs in <Directory>, <Location> tags, etc. and the dynamic content is referenced with the JkMount directives.
