Hello!
I am using cassandra on a ubuntu machine and installed it from the
binary found on the cassandra home page.
However, I did not find any scripts to start it up at boot time.
Where can I find this kind of script?
Thanks a lot in advance

Hi, this is what I do, you can add the watchdog to rc.local
/%S[%m]%s %~ %# cat watchdog
#!/bin/bash
#
# This script is to check every $INTERVAL seconds to see
# whether cassandra is work well
# and restart it if neccesary

PORT=9160
INTERVAL=2
CASSANDRA=/opt/cassandra
check() {
netstat -tln|grep LISTEN|grep :$1
if [ $? != 0 ]; then
echo "restarting cassandra"
$CASSANDRA/bin/stop-server
sleep 1
$CASSANDRA/bin/start-server
fi
}
while true
do check $PORT
sleep $INTERVAL
done/
