event.d/init.d script

event.d script

This is an event.d-script for the new Ubuntu Upstart.

The event gets started/respawned on runlevels 2-5. If you change to level 0, 1 or 6, the process gets stopped/killed. Manual start/stop works through the same commands start and stop. With status you can check the status.

# manages Solr search engine

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

kill timeout 30
respawn

script
    cd /home/sysadmin/extension/ezfind/java
    exec /usr/bin/java -jar start.jar
end script

init.d script

This does the same using the traditional init.d-way.

After creation of the script in /etc/init.d you also have to make the symlinks in the rc.2..rc.5-directories.
