I would like to run the ELK stack in a FreeBSD Jail on an FreeNAS host. I have a hard time to get an simple init/rc.d script to work.

#!/bin/sh . /etc/rc.subr name=logstash rcvar=logstash_enable load_rc_config $name logstash_bin="/usr/local/bin/${name}/bin/${name}" logstash_conf="/usr/local/etc/${name}/${name}.conf" logstash_pid="/var/run/${name}.pid" command="/usr/sbin/daemon" command_args="-f -p ${logstash_pid} ${logstash_bin} -f ${logstash_conf} web" run_rc_command "$1"

I can execute the script and it will return that logstash now started but "ps" tells me another story.

root@logstash:/var/log # service logstash start Starting logstash. root@logstash:/var/log # ps aux USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND root 2963 0.0 0.0 12076 1636 ?? SsJ 3:58PM 0:00.02 /usr/sbin/syslogd -s root 3014 0.0 0.0 14176 1592 ?? SsJ 3:58PM 0:00.01 /usr/sbin/cron -s root 57344 0.0 0.0 17564 3736 0 SJ 5:31PM 0:00.18 csh root 61945 0.0 0.0 14220 1768 0 R+J 7:24PM 0:00.00 ps aux root@logstash:/var/log #

If I print the content of $command and $command_args out and enter it manually it works perfectly.

output from "command="echo /usr/sbin/daemon":

/etc/rc.d/logstash: WARNING: cannot read shebang line from echo /etc/rc.d/logstash: WARNING: run_rc_command: cannot run echo /usr/sbin/daemon

Any ideas what I'm doing wrong?

  • Please try command="echo /usr/sbin/daemon". Does it print the full command? Commented Oct 5, 2014 at 6:12

Are you sure the logstash_bin is right? "/usr/local/bin/logstash/bin/logstash" looks suspicious.

There is also an RC debugging mechanism (eg "rc_debug=true /usr/local/etc/rc.d/logstash start"), but I'm not sure if it will help you in this case.
