just add a --chuid logstash:logstash option, like:

  start () {
      log_daemon_msg "Starting $mode" "$name"
      if start-stop-daemon --start --quiet --oknodo --pidfile "$pid_file" --chuid logstash:logstash -b -m --exec $command; then
          log_end_msg 0
      else
          log_end_msg 1
      fi
  }

Hello,
How should I use this script?
Should I create a file named logstash-reader and logstash-shipper?
Where should I put the file, logstash-reader and logstash-shipper?

then
excute
update-rc.d logstash-shipper defaults
update-rc.d logstash-reader defaults
commands in anywhere?

After that?
What command I should type to start the logstash?
Something like logstash-reader start?

Thank you very much.

Andy

@AndyCCChang, I know this may be a little late, but for future users

To use this script:
create logstash-reader in /etc/init.d/
put the reader code from above into that file
make it executable with: chmod +x logstash-reader
run: update-rc.d logstash-reader defaults

Do the same for the shipper on the other machine (typically, depending on your setup. For example, I'm only running the reader)
[These insctructions were taken from StackOverflow, look here for more info: http://stackoverflow.com/questions/7221757/run-automatically-program-on-startup-under-linux-ubuntu]

logstash-reader will then be run at startup
you can also use the commands
service logstash-reader status/start/restart/stop
(these should be pretty self-explanatory)

It also looks like the logstash cookbook is down :(

First of all, thank you for this gist! It's really helpful. However it's not working for me, and I'm not sure where the problem is. I copied your gist and adjusted the paths. This is the exception I am getting:

logstash@asgard:~$ service logstash-reader status
/etc/init.d/logstash-reader: invalid arguments
 * could not access PID file for logstash-reader
logstash@asgard:~$ service logstash-reader start
/etc/init.d/logstash-reader: invalid arguments
 * could not access PID file for logstash-reader
 * Starting reader logstash-reader                                                              
/etc/init.d/logstash-reader: 28: /etc/init.d/logstash-reader: start-stop-daemon: not found
                                                                                         [fail]

Do you have any ideas what could be the problem?

If you edited the logstash_bin= line, you may need to make sure that the command is preceded by --.

logstash_bin="-- /opt/logstash/logstash-1.4.2/bin/logstash"

I got the same error:

• could not access PID file for logstash-shipper
• Starting shipper logstash-shipper

i tried with above soln but still no luck ...plss help

How we make use of multiple pipelines when logstash is running as a service?
