RFE idea: Add port offset system property to Tomcat
Hi all,
I was just doing some testing and got had an idea for spinning up new
instances of tomcat. JBoss has this system property
"-Djboss.socket.binding.port-offset" that I think would be useful for
tomcat. As en example, setting the property to 100 on startup would
add "100" to all port bindings on the server (e.g. with a vanilla
install it would cause tomcat to run on 8105, 8180, and 8109). This
prevents uses from having to use a fancy sed (or whatever Windows has)
to update the port bindings for every new install. Does anyone else
see any value to adding this feature?
Thanks,
Coty

I created https://bz.apache.org/bugzilla/show_bug.cgi?id=61171. I'm
not sure what degree of difficulty this is, so I'll let mark or
someone else tag it if appropriate.

If you open a ticket and think that it's appropriate, please tag it as
"Beginner".

It would have placeholder support (as do all attributes in server.xml)
so yes, system properties could be used - with a small edit to
server.xml. It would have to be on Server.

@Mark: guess you are thinking to server.xml? then it would have placeholder
support so still a system property somehow no?
+1 anyway, sounds very useful!

Yeah, sure. I think the biggest benefit is not having to manually
configure all the ports, so it could be an env var in the startup
script or some other setting somewhere. JBoss has a sysprop, so I'm
used to starting it that way, but if you like another method let me
know, I'll open an enhancement request and give it a shot.

I like the idea a lot - apart from the system property part. Would this
still be as useful if it wasn't a system property?
