At the moment I have to go to /usr/java/apache-solr-1.4.0/example
and then do:
java -jar start.jar
How do I get this to start automatically on boot?
I'm on a shared Linux server.
As you're on a shared Linux box, you'll have to ask the system administrator to do the following, probably.
Create a startup script in /etc/init.d/solr
.
Copy this code, my Solr startup script, into that file:
#!/bin/sh
# Prerequisites:
# 1. Solr needs to be installed at /usr/local/solr/example
# 2. daemon needs to be installed
# 3. Script needs to be executed by root
# This script will launch Solr in a mode that will automatically respawn if it
# crashes. Output will be sent to /var/log/solr/solr.log. A PID file will be
# created in the standard location.
start () {
echo -n "Starting solr..."
# Start daemon
daemon --chdir='/usr/local/solr/example' --command "java -jar start.jar" --respawn --output=/var/log/solr/solr.log --name=solr --verbose
RETVAL=$?
if [ $RETVAL = 0 ]
then
echo "done."
else
echo "failed. See error code for more information."
fi
return $RETVAL
}
stop () {
# Stop daemon
echo -n "Stopping solr..."
daemon --stop --name=solr --verbose
RETVAL=$?
if [ $RETVAL = 0 ]
then
echo "Done."
else
echo "Failed. See error code for more information."
fi
return $RETVAL
}
restart () {
daemon --restart --name=solr --verbose
}
status () {
# Report on the status of the daemon
daemon --running --verbose --name=solr
return $?
}
case "$1" in
start)
start
;;
status)
status
;;
stop)
stop
;;
restart)
restart
;;
*)
echo $"Usage: solr {start|status|stop|restart}"
exit 3
;;
esac
exit $RETVAL
Then run:
chkconfig --add solr
Or (on Ubuntu):
update-rc.d solr defaults
... or, if your Linux distribution doesn't have chkconfig
(or update-rc.d
), link /etc/init.d/solr
to /etc/rc3.d/S99solr
and /etc/rc5.d/S99solr
and /etc/rc3.d/K01solr
and /etc/rc5.d/K01solr
:
% ln -s /etc/init.d/solr /etc/rc3.d/S99solr
% ln -s /etc/init.d/solr /etc/rc5.d/S99solr
% ln -s /etc/init.d/solr /etc/rc3.d/K01solr
% ln -s /etc/init.d/solr /etc/rc5.d/K01solr
Now on reboot Solr will startup in run levels 3 and 5 (console with network & full GUI).
To start solr manually run:
% /etc/init.d/solr start
