loadbalancing with tomcat only and unable to bring admin and manager pages
Hi,
I've to put together a tomcat web setup for a project
with loadbalancing and/or failover (between 2 sites).
I read that this is possible with mod_jk connector.
i'm running tomcat 4.1.12. I've a few questions any
and all help is truly appreciated.
1. what's the best way to monitor the health of
tomcat?
2. Is the default connector that comes packaged with
tomcat capable of doing failover,loadbalancing or do I
need to have apache in the front and a connector in
between.
3. Is it possible to redirect tomcat to port 80 (or do
i need apache in the front again) to avoid having the
users type 8080 everytime?
4. while starting tomcat as user "tomcat" i keep
getting "tomcat-users permission denied". only
wrokaround I found was to either give the user write
access to the conf dir or comment out the memoryrealm
altogether. One, is it a good idea to give the suer
write access to conf dir. Two i have to setup a user
list (currently locally) to allow access to tomcat, if
i comment out the memeoryrealm then how do i
authenticate my users.
5. Lastly, I can't get admin or manager applications
to work. I keep getting HTTP Status 403 - Access to
the requested resource has been denied
Please help....Thanks to all in advance.

Ben,
Thanks for te reply (so far the only one). Can you
please elaborate on the monitoring part? I meant to
ask what are the symptoms (are there generic
meassges?) to grep for from the log files to monitor
the health of tomcat.
Thanks

There are a number of ways to do this: process watching, scripts that
access the certain URLs and match the result with what is expected,
third-party monitors like Big Brother, etc.

You need to have Apache out in front with a connector in between.

You can have Tomcat use port 80, but you have to change the server.xml
to reflect that and start Tomcat as Root. However, you would not have
the load-balancing/failover.

I give the user 'Tomcat' the ownership of the Tomcat directory. Should
be no pproblem with that, as log as the conf directory is not in the
'ROOT' docbase directory.
The answer above should fix two.
