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:
<solr persistent="true" sharedLib="lib">
<cores adminPath="/admij/cores">
<core name="core0" instanceDir="cores/core0" />
<core name="core1" instanceDir="cores/core1" />
</cores>
</solr>
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 gave that a try and it didn't change anything.

Hi Joshua,
Can you try updating your solr.xml as follows:
Specify
"<core name="core0" instanceDir="/core0" />" instead of
"<core name="core0" instanceDir="cores/core0" />"
Basically remove the extra text "cores" in the core element from the
instanceDir attribute.
Just try and let us know if it works.

I was finally able to figure out the issue here. It was the solr.QueryElevationComponent exception in the logs. 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.

No, that was a typo -- the config file is correct with admin/cores. Thanks for pointing out the mistake here.

Was that a cut and paste? If so, the /admij/cores is presumably incorrect, and ought to be /admin/cores

One time when we had that problem, it was because one or more cores had a broken XML configuration file.
Another time, it was because solr/home was not set right in the servlet container.
Another time it was because we had an older EAR pointing to a newer release Solr home directory. Given what you did, I suppose that is possible in your case, too.
In all cases, the Solr log provided hints as to what was going wrong.

Now this is interesting.
If I have defaultCoreName in my solr.xml (on 3.4.0), the /solr URL only
shows one admin link, which takes me to the /solr/admin/ page for my
default core. On that page, I do have links to all the other core admin
pages, as usual.
If I don't have defaultCoreName, /solr shows admin links for all defined
cores.
A quick search didn't turn up any Jira issues for this. Is this
intended behavior?
Thanks,
Shawn

I see "Welcome to Solr!" and "Solr Admin" below that as a link. When I click through the link, I get the 404 error, "missing core name in path".

Just go to localhost:8983 (or whatever other port you are using) and use
this path to see all the cores available on the box:
In your example this should give you a core list:
http://solrhost:8080/solr/

Hi Shawn,
Thanks for the quick response.
I can't get any of those combinations to work.
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.
Thanks,

When you enable multiple cores, the URL syntax becomes a little
different. On 1.4.1 and 3.2.0, I ran into a problem where the trailing
/ is required on this URL, but that problem seems to be fixed in 3.4.0:
http://host:port/solr/corename/admin/
If you put a defaultCoreName="somecore" into the <cores> tag in
solr.xml, the original /solr/admin URL should work as well. I just
tried it on Solr 3.4.0 and it does work. According to the wiki, it
should work in 1.4 as well. I don't have a 1.4.1 server any more, so I
can't verify that.
