Multiple geoserver / or multiple tomcats?

Hi,

I would like to have two geoserver instances running on one linux ubuntu server. The reason is to be able to offer a wms service for a particular project without the clutter of other layers in the wmsgetcapabilities doc. I would like to just offer a series of layers 20 or so, which will have one organised nomenclature thus making it easier to identify the layers one wants. I find one of the most frustrating things about wmsgetcapabilities docs is the amount of layer info which one has to rumage through.

Anyway...My solution is to install either

1. geoserver again inside tomcat6, or

2. Tomcat6 again and put another geoserver inside

Would anyone have any experience of the best solution?

thanks,

Robert

Re: Multiple geoserver / or multiple tomcats?

Thanks for the reply.

The problem with having a shared geoserver_datadir is that I will then inherit all of the preconfigured layers from the first instance! This is exactly what I do not want...ie. lots of layers in my wmsGetCapabilities doc.

What is the problem with dropping another geoserver .war file into tomcat, renaming it "geoserver2", changing the default port to :8181 and giving it a different datadir directory?

cheers,

Rob

Hi,

you need to run geoserver on separate instances of tomcat. If you are
only reading and showing maps, then you ought to use the same data
directory for both geoservers, however if you plan to use the
integrated GWC you will need to setup a separate cache directory for
one one the geoserver by setting environment like
-DGEOWEBCACHE_CACHE_DIR=<path to folder with geowebcache.xml>

Re: Multiple geoserver / or multiple tomcats?

ok.

So how do I reduce the number of configured layers for one instance of geoserver and not for the other if they both use the same datadir?

cheers,

Hi,

you can have it anyway you like but its better you point both of them
to the same data directory, that way you will have to maintain one
data directory for both, the problem will only come when using cached
layers that is if you are using it.

Hi Robert,
you can have have several Geoserver instances in same Tomcat or at
least that was the case with the 1.7 branch. There may be some problems
with GWC and maybe with some other things, but besides that, there
shouldn't be any major obstacles. The port is same for all instances,
only instance name must be different.

Re: Multiple geoserver / or multiple tomcats?

Thanks.

I am using gwc for my first instance but not necessarily for my second. Would a multiple geoserver architecture break GWC for the first instance of geoserver, the second, or both? Is there a way to disconfigure/remove gwc from the second instance?

thanks,

Rob

I think, if there is problems with GWC, you can remove the gwc.jar from
the instance you wouldn't want to use it in.
But I'm not 100% sure, if I'm right on these issues. I have had, if I
recall right, some 5-6 instances of Geoserver in same Tomcat few years
back, but they were 1.7 branch. So maybe things have changed.. though I
doubt.

Andrea -

I have some layers that I want to protect with our local
centralized authentication server (CAS) and some layers that I don't. My
solution is to install two Geoserver instances in one Tomcat and allow
access to one only through a CAS-protected Apache httpd with mod_jk.
Each Geoserver has it's own data directory.

Besides the problem of how to restrict access to the secured
Geoserver via Tomcat's port, are there any problems with running two
Geoservers in one tomcat instance? The preceding posts in this thread
sounded unsure.

Permgen exhaustion can be a problem, GeoServer uses a ton of it because it's
made of a very large amount of classes.
For reasons we could not determine, it also leask permgen, that, is,
if you redeploy
GeoServer without restarting tomcat the permgen memory used by GeoServer
is not released.

This means you cannot redeploy the two GeoServer instances independently,
since the safe way to do that is to restart Tomcat.

Another issue is vector rendering scalability, the Sun/Oracle java2d
implementation
is fast but scales poorly, and the synchronization lock is held at the
JVM level,
meaning that if you run two GeoServer in the same process they will synch out
each other.
That's why we normally deploy one Tomcat + GeoServer every 2 or 4
available cores,
to ensure better scalability (see this presentation for details:
http://demo.geo-solutions.it/share/foss4g2011/gs_steroids_sgiannec_foss4g2011.pdf)
