how to get multicore to work?

[xdzgor <pk...@alphasolutions.dk>]

Hi - I can't seem to get "multicores" to work. I have a solr installtion
which does not have a "solr.xml" file - I assume this means it is not
multicore.

If I create a solr.xml, as described on
http://wiki.apache.org/solr/CoreAdmin, my solr installation fails - for
example I get 404 errors when trying to search, and "solr/admin" does not
work.

Is there more than simply making solr.xml to get multicores to work?

Thanks,
Peter

If you take a look in the examples directory there is a directory called
multicore. This is an example of the solrhome of a multicore setup.

Otherwise take a look at the logged output of Solr itself. It should tell
you what is wrong with the setup

You need to elaborate on "It all stops working" ... what does that mean? 
what are you trying to do? and what errors are you getting?

when i take an existing (functional) Solr 1.4 SolrHome dir, and drop that 
solr.xml file into it, everything works as expected for me....

  1. Solr starts up 
  2. This URL lists a link to the admin page for a single core named 
     "core0"...
     http://localhost:8983/solr/
  3. This URL let's me use core0...
     http://localhost:8983/solr/core0/admin/
  4. this URL (specified in your solr.xml) let's my admin the cores 
     (ie: view-status/add/remove/reload) ...
     http://localhost:8983/solr/admin/cores

Thanks for the comments. I still can't get this multicore thing to work!

Here is my directory structure:

d:
__apachesolr
____lucidworks
______lucidworks
________solr
__________bin
__________conf
__________lib
________tomcat

There is no solr.xml, and solr.solr.home points to
d:\apachesolr\lucidworkd\lucidworks\solr

As it stands, solr works fine, and sites like
http://locahost:8983/solr/admin also work.

As soon as I put a solr.xml in the solr directory, and restart the tomcat
service. It all stops working.
<solr persistent="false">
  <cores adminPath="/admin/cores">
    <core name="core0" instanceDir="." />
  </cores>
</solr>

Any idea where I can look?
Where is the solr startup log written?

Thanks,
Peter

- solr.xml have to reside in the solr.home dir. you can setup this with the java-option
  -Dsolr.solr.home=xxxx
- admin is per core, so solr/CORENAME/admin will work

it is quite simple to setup.
