cassandra Cassandra as a Service Linux

Example

1. Create the /etc/init.d/cassandra startup script.

2. Edit the contents of the file:

   #!/bin/sh
   #
   # chkconfig: - 80 45
   # description: Starts and stops Cassandra
   # update daemon path to point to the cassandra executable
   DAEMON=<Cassandra installed directory>/bin/cassandra
   start() {
           echo -n "Starting Cassandra... "
           $DAEMON -p /var/run/cassandra.pid
           echo "OK"
           return 0
   }
   stop() {
           echo -n "Stopping Cassandra... "
           kill $(cat /var/run/cassandra.pid)
           echo "OK"
           return 0
   }
   case "$1" in
     start)
           start
           ;;
     stop)
           stop
           ;;
     restart)
           stop
           start
           ;;
     *)
           echo $"Usage: $0 {start|stop|restart}"
           exit 1
   esac
   exit $?
   

3. Make the file executable:

   sudo chmod +x /etc/init.d/cassandra

4. Add the new service to the list:

   sudo chkconfig --add cassandra

5. Now you can manage the service from the command line:

   sudo /etc/init.d/cassandra start
   sudo /etc/init.d/cassandra stop
   sudo /etc/init.d/cassandra restart
