### END INIT INFO
# Example of a very simple *nix init script that delegates commands to the bin/solr script
# Typical usage is to do:
#
# cp bin/init.d/solr /etc/init.d/solr
# chmod 755 /etc/init.d/solr
# chown root:root /etc/init.d/solr
# update-rc.d solr defaults
# update-rc.d solr enable
# Where you extracted the Solr distribution bundle

# variables used by the bin/solr script. It's highly recommended to define this script so
# that you can keep the Solr binary files separated from live files (pid, logs, index data, etc)
# see bin/solr.in.sh for an example
