sunspot.yml

### config/sunspot.yml

    production:
      solr:
        hostname: localhost
        port: 8080
        log_level: WARNING
        path: /solr/my_collection
        # read_timeout: 2
        # open_timeout: 0.5

THANK YOU VERY MUCH!!!

I would fix only:

cp <RAILS_ROOT>/solr/conf/schema.xml /var/lib/tomcat7/solr/<my_collection>
cp <RAILS_ROOT>/solr/conf/solrconfig.xml /var/lib/tomcat7/solr/<my_collection>

for

cp <RAILS_ROOT>/solr/conf/schema.xml /var/lib/tomcat7/solr/<my_collection>/conf/
cp <RAILS_ROOT>/solr/conf/solrconfig.xml /var/lib/tomcat7/solr/<my_collection>/conf/

I also needed to copy collection1 from solr/collection1 to root (/var/lib/tomcat7/solr)
cp -r solr/collection1/ .

And then I accessed ui localhost:8080/solr to add my core "Core Admin". In the end I also make it only available to localhost:

cd /var/lib/tomcat7/conf

And edit server.xml

    <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               URIEncoding="UTF-8"
               redirectPort="8443" />

I added address to restrict access to only localhost.

    <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               URIEncoding="UTF-8"
               address="127.0.0.1"
               redirectPort="8443" />

PS: I did that for my version of solr (solr-4.10.3) + tomcat7

and I also needed to add my core
curl "http://localhost:8080/solr/admin/cores?action=CREATE&name=production&instanceDir=production&config=solrconfig.xml&schema=schema.xml&dataDir=data&persist=true"

persist=truemakes the magic, otherwise every time you restar server you lost your core conf
