I don't know if this will help but I usually add a dataDir element to
each cores solrconfig.xml to point at a local data folder for the core
like this:
<!-- Used to specify an alternate directory to hold all index
data
other than the default ./data under the Solr home.
If replication is in use, this should match the replication
configuration. -->
<dataDir>${solr.data.dir:./solr/core0/data}</dataDir>

Subject: need some help with a multicore config of solr3.6.0+tomcat7.
mine reports: "Severe errors in solr configuration."
i've installed tomcat7 and solr 3.6.0 on linux/64
i'm trying to get a single webapp + multicore setup working. my efforts
have gone off the rails :-/ i suspect i've followed too many of the
wrong examples.
i'd appreciate some help/direction getting this working.
so far, i've configured
grep 8888 /etc/tomcat7/server.xml -A2 -B2

after tomcat restart,
ps ax | grep tomcat

i see as expected

now, i'm trying to set up multicore properly. i configured,
cat /srv/www/solrbase/solr.xml
<?xml version="1.0" encoding="UTF-8" ?>
<solr persistent="false">
<cores adminPath="/admin/cores">
<core name="core0" instanceDir="core0" />
<core name="core1" instanceDir="core1" />
</cores>
</solr>
then
mkdir -p /srv/www/solrbase/{core0,core1}
cp -a /srv/www/solrbase/conf /srv/www/solrbase/core0/
cp -a /srv/www/solrbase/conf /srv/www/solrbase/core1/
if i nav to
http://localhost:8888/solr/core0
i get,
HTTP Status 500 - Severe errors in solr configuration. Check
your log files for more detailed information on what may be
wrong. If you want solr to continue after configuration errors,
change:
<abortOnConfigurationError>false</abortOnConfigurationError> in
solr.xml

at this point i'm completely unclear whether i've misconfigured
something, failed to install a dep, etc.
