Core admin: create new core
The core admin CREATE function requires that the new instance dir and
schema/config exist already. Is there a particular reason for this? It
would be incredible convenient if I could create a core with a new
schema and new config simply by calling CREATE (maybe providing the
contents of config.xml and schema.xml as base64 encoded strings in HTTP
POST or something?).
I'm guessing this isn't currently possible?

Unless you are in SolrCloud mode, creating cores via the admin UI (or
the /admin/cores HTTP API) requires that the core directory and its conf
subdirectory with solrconfig.xml, schema.xml, and other potential files
must already exist in the indicated location. There's a note right on
the screen for "Add Core" that says this: "instanceDir and dataDir need
to exist before you can create the core". This was the case for 4.x as
well as 5.0.
That note is slightly misleading ... the dataDir does not need to exist,
just instanceDir and the conf directory. Solr will create the dataDir
and its contents, if the user running Solr has permission.
There is a configsets functionality that's new in recent versions which
very likely will make it possible to create a core completely from
scratch within the admin UI in non-cloud mode, but I do not know
anything about using it, and I do not think the functionality is exposed
in the admin UI yet.
Learning about cores and/or collections and how to create them is a
hugely important part of using Solr. In 4.x, users did not need to do
anything to get their first core, and that fact has led to many
problems. New users don't know how to add a core, and many do not even
know about cores at all. This requires that they must learn about the
core/collection concepts, and many of them cannot find any info about
the procedure, so they ask for help. I am glad to help out both here
and on the IRC channel, but it improves the experience of everyone
involved if users become familiar with the concept and methods on their own.
Thanks,
Shawn

Solr 5 has been released. I was just giving a try and come across the same
issue. As I heard over from some documentation, Solr 5 doesn't come with
default core (example in earlier versions). And this requires us to create
a core from Solr Admin. When I tried to create the core, I get the following
error
Error CREATEing SolrCore 'inventory': Unable to create core [inventory]
Caused by: Can't find resource 'solrconfig.xml' in classpath or
'/Users/manjunath.reddy/Programming/Solr/solr-5.0.0/server/solr/inventory/conf'
So I had to manually create the core based on my previous experience with
Solr 4.10 version.
I guess its quite misleading for new users of Solr. I like the older
versions of Solr that comes with default cores so that It would be easier to
follow up on.
I have attached screen shots for the reference. Is there a work around for
this?

Well, the easiest way is probably the bin/solr script.
Try typing in bin/solr create_core -help

creating a little API that takes schema/config as input,
creates the files and then uses the core admin CREATE request. Works
like a charm.
RE/ Can you help or post how you made this API
Thank you

If you're really bored, anything you'd like to do for SOLR-4779
would be great!

I ended up creating a little API that takes schema/config as input,
creates the files and then uses the core admin CREATE request. Works
like a charm. If I get bored I might just turn it into a solr plugin or
something.
Ta for the suggestions!

Right, this has been an issue for a while, there's no current
way to do this.
Someday, I'll be able to work on SOLR-4779 which should
go some toward making this work more easily. It's still not
exactly what you're looking for, but it might work.
Of course with SolrCloud you can specify a configuration
set that is used for multiple collections.
People are using Puppet or similar to automate this over
large numbers of nodes, but that's not entirely satisfactory
either in our case I suspect.
FWIW,
Erick
