simple and stupid Arch Linux rc.d script for starting and stopping puma (http://puma.io) with certain rails app

puma_rc.d.sh

#!/bin/bash

. /etc/rc.conf
. /etc/rc.d/functions
. /etc/profile

DAEMON=prozatorium
PIDFILE=/path/to/pidfile
app_path=/path/to/rails_app
config=config/puma.rb
logfile=log/puma.log

case "$1" in
 start)
   stat_busy "Starting $DAEMON"
   [ -z "$PID" ] && cd $app_path && bundle exec puma --pidfile $PIDFILE -C $config &>/dev/null >> $logfile &
   if [ $? = 0 ]; then
     add_daemon $DAEMON
     stat_done
   else
     stat_fail
     exit 1
   fi
   ;;
 stop)
   PID=`cat $PIDFILE`
   stat_busy "Stopping $DAEMON"
   [ -n "$PID" ] && kill $PID &>/dev/null
   if [ $? = 0 ]; then
     rm_daemon $DAEMON
     stat_done
   else
     stat_fail
     exit 1
   fi
   ;;
 restart)
   $0 stop
   sleep 1
   $0 start
   ;;
 *)
   echo "usage: $0 {start|stop|restart}"
esac

These (like everything else) tend to look a lot better on OpenBSD:

#!/bin/sh

# Puma startup script

# chmod +x /etc/rc.d/myapp

# http://cvsweb.openbsd.org/cgi-bin/cvsweb/ports/infrastructure/templates/rc.template

. /etc/rc.d/rc.subr

myapp_home="/home/www/myapp"

pumactl="/usr/local/bin/pumactl"
puma_config="-C ${myapp_home}/config/puma.rb"
puma_state="-S ${myapp_home}/tmp/puma.state"

rc_start() {
  ${rcexec} "${pumactl} ${puma_state} start ${puma_config}"
}

rc_reload() {
  ${rcexec} "${pumactl} ${puma_state} restart ${puma_config}"
}

rc_stop() {
  ${rcexec} "${pumactl} ${puma_state} stop"
}

rc_check() {
  ${rcexec} "${pumactl} ${puma_state} status"
}

rc_cmd $1

Or FreeBSD:

#!/bin/sh

# Puma startup script

# chmod +x /usr/local/etc/rc.d/myapp

# https://freebsd.org/doc/en/articles/rc-scripting/rcng-dummy.html

. /etc/rc.subr

name=myapp
rcvar=myapp_enable

myapp_home="/home/www/myapp"

pumactl="/usr/local/bin/pumactl"
puma_config="-C ${myapp_home}/config/puma.rb"
puma_state="-S ${myapp_home}/tmp/puma.state"

start_cmd="${pumactl} ${puma_state} start ${puma_config}"
stop_cmd="${pumactl} ${puma_state} stop"
restart_cmd="${pumactl} ${puma_state} restart"

load_rc_config $name
run_rc_command "$1"
