Trouble configuring multicore / accessing admin page
Hello,
I am trying to get SOLR working with multiple cores and have a problem
accessing the admin page once I configure multiple cores.
Problem:
When accessing the admin page via http://solrhost:8080/solr/admin, I get a 404,
"missing core name in path".
Question: when using the multicore option, is the standard admin page still
available?
Environment:
- solr 1.4.1
- Windows server 2008 R2
- Java SE 1.6u27
- Tomcat 6.0.33
- Solr Experience: none
I have set -Dsolr.solr.home=c:\solr and within that I have a solr.xml with the
following contents:
I have copied the example/solr directory to c:\solr and have populated that
directory with the cores/{core{0,1}} as well as the proper configs and data
directories within.
When I restart tomcat, it shows a couple of exceptions related to
queryElevationComponent and null pointers that I think are due to the DB not
yet being available but I see that the cores appear to initialize properly
other than that
So the problem I'm looking to solve/clarify here is the admin page - should
that remain available and usable when using the multicore configuration or am I
doing something wrong? Do I need to use the CoreAdminHandler type requests to
manage multicore instead?
Thanks,

I've added the defaultCoreName="core0" into the solr.xml and restarted and tried the following combinations: http://host:port/solr/admin http://host:port/solr/admin/ http://host:port/solr/core0/admin/ … (and many others) I'm stuck on 1.4.1 at least temporarily as I'm taking over an application from another resource and need to get it up and running before modifying anything so any help here would be greatly appreciated.

When I click through the link, I get the 404 error, "missing core name in path". Thanks, Josh Miller Open Source Solutions Architect (425) 737-2590 http://itsecureadmin.com/

Once I commented out the related section in each core conf/solrconfig.xml file and restarted tomcat, I could then see the admin page link for each core and click through to manage them. Thanks!
