Seperate tomcats - one apache
Hi all,
I'm having some fun with some applications supplied to us that may be
casuing a problem wiht each other, i.e. one application may be causing the
whole tocat environment to fail - thus affecting the others.
I'm toying with the idea of trying to run a signle apache but with
multiple tomcats - one per application. Does anyone have any views on this
?
Cheers - Steve

I've been trying to do it for over a day, with mod_jk, with no luck.
I think at this point I will have to use 2 complete installs of Tomcat...up
'til now I have trying to use one install of Tomcat but two instances via
CATALINA_BASE.

It doesn't work at all. Believe me, I've now spent 14 hours trying to make
it work.
I posted yesterday exactly what I have done so far ("Help with one Apache,
mod_jk, two Tomcats, no load balancing").
http://host1.com:8080 -> Tomcat 1 works great
http://host2.com:8081 -> Tomcat 2 works great
Apache Virtual Host host1 (http://host1.com) -> Tomcat 1
Apache Virtual Host host2 (http://host2.com) -> ALSO Tomcat 1
I've tried many variations of workers.properties, even setting up load-
balanced workers as suggesting in http://www.ubeans.com/tomcat (private JVM
section) even though I don't want load-balancing at all.
mod_jk.log:

I don't know about you, but line number one there looks pretty fishy to
me...I have no idea what "shostn" means (shared host name?), but it
shouldn't be "host1", it should be "host2", and the worker found should be
"tomcat2", not "tomcat1".
I am definitely open to suggestions on how to make this work, but I can
tell you that I am no stranger to setting up mod_jk (different port
numbers, etc), and at this time this DOES NOT work for me with Apache .43,
Tomcat 4.1.18, Solaris 8, and built-from-source mod_jk.

I routinely run via the CATALINA_BASE method for multiple instances and have
no problems.
Using mod_jk, all you have to do is define the connectors to be on different
ports, and then configure each servlet engine to run mod_jk on a different
port.
