Installing Solr 3.6.0 on Ubuntu from source

1. Make a solr user

    tar -zxf apache-solr-3.6.0.tgz
    mv apache-solr-3.6.0 /opt/solr
    chown -R solr /opt/solr

4. Make log directory

    mkdir /var/log/solr
    chown solr /var/log/solr

    description "Solr"


    start on runlevel [2345]
    stop on runlevel [016]

    <solr persistent="false">
      <cores adminPath="/admin/cores">
        <core name="example.com" instanceDir="/etc/solr/example.com">
