hammady / solr.service

Created January 9, 2017 08:18

systemd service file for Apache SOLR

	# put this file in /etc/systemd/system/ as root
	# below paths assume solr installed in /opt/solr, SOLR_PID_DIR is /data
	# and that all configuration exists in /etc/default/solr.in.sh which is the case if previously installed as an init.d service
	# change port in pid file if differs
	# note that it is configured to auto restart solr if it fails (Restart=on-faliure) and that's the motivation indeed :)
	# to switch from systemv (init.d) to systemd, do the following after creating this file:
	# sudo systemctl daemon-reload
	# sudo service solr stop # if already running
	# sudo systemctl enable solr
	# systemctl start solr
