bootstrap_confdir does not necessarily correlate to a core. It uploads a
set of configuration files that might be used by one core or many cores.
So you want to create multiple configurations, and then assign the right
cores to the right set of configuration files.

For all but the simplest demos, you really have to edit the zookeeper
config yourself. There are tools to help you do this. See:

If you don't want to upload the files yourself to zk, you can start Solr
multiple times with different bootstrap_confdir and
collection.configName values.

So you might start up with:

-Dbootstrap_confdir=./solr/conf1 -Dcollection.configName=coreconf1

then with:

-Dbootstrap_confdir=./solr/conf2 -Dcollection.configName=coreconf2

and a third time with:

-Dbootstrap_confdir=./solr/conf3 -Dcollection.configName=coreconf3

This would give you three different configurations - you would then edit
the zookeeper info to point each collection (essentially a SolrCore at
this point) to the right configuration files:
