I am trying to run Cassandra as a service on OpenSuse (Leap 42.1).

I have tried installing with apache-cassandra-2.1.11-bin.tar.gz and then copying /etc/init.d/cassandra from https://gist.github.com/sgomezvillamor/5458309. However, the startup script is not designed for OpenSuse, as the system.log says:

/etc/init.d/cassandra: line 30: daemon: command not found.

The problem would not exist if there would be an installer that would create the scripts correctly, similarly as there are for some other OSs. Searching for an installation package, I found http://www.datastax.com/dev/blog/announcing-rpms-cassandra and tried to look for an rpm in rpm.riptano.com but I cannot figure out which one would work in OpenSuse.

Which of those packages would work for OpenSuse? Or, how should I modify the startup script for Suse-fying it?

I would check these instructions which are for Cassandra 2.1: Installing DataStax Community 2.1 on RHEL-based systems.

I'm not sure whether that will get you 100% there on an OpenSUSE system, but should get you very close.

I got it to work with /etc/init.d/cassandra file:

#!/bin/bash
#
# /etc/init.d/cassandra
#
# Startup script for Cassandra
# 
# chkconfig: 2345 20 80
# description: Starts and stops Cassandra

#. /etc/rc.d/init.d/functions
