Cassandra automatic startup script on ubuntu

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

Sebastien

The debs produced by Eric Evans, and the others that I've been building,
have an init.d script in them.

You can find Eric's debs here:

http://wiki.apache.org/cassandra/DebianPackaging

Or the ones I build and test on Ubuntu releases here:

https://launchpad.net/~cassandra-ubuntu/+archive/stable

I just uploaded 0.7.0, so it will still have 0.6.8 in it while the
builds finish and the debs are published.

You can also use the apt-get repository version, which installs the startup
script.  On http://wiki.apache.org/cassandra/CloudConfig, see the Cassandra
Basic Setup section.  It applies to any debian based machine, not just cloud
instances.

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
# by donal 2010-01-11
#
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
