Convertendo o script do init para o systemd

Question

Estou mudando do Ubuntu 11 para o 16 e gostaria de converter scripts customizados para trabalhar com o Ubuntu 16

Eu iniciei e concluí o primeiro script de inicialização , mas preciso de ajuda no segundo script de inicialização . Eu completei parte disso, mas não consigo encontrar exemplos on-line para concluí-lo.

Primeiro script de inicialização

description "worker process to start multiple consumers - q9 mt03 local queue"
author      "mt dev team"

start on runlevel [2345]
stop on runlevel [!2345]

env NUM_WORKERS=20

pre-start script
  for i in 'seq 1 $NUM_WORKERS'
  do
    start consumer-localhost N=$i
  done
end script

Versão Systemd

### BEGIN INIT INFO 
Provides: localqueue 
Default-Start: 2 3 4 5 
Default-Stop: 0 1 6 
Short-Description: start and stop service rabbitmq servers 
Description: worker process to start multiple consumers - q9 mt03 local queue 

Environment NUM_WORKERS=20 
ExecStartPre 
for i in 'seq 1 $NUM_WORKERS' 
do 
start consumer-localhost N=$i 
done 
ExecStopPost 
### END INIT INFO

Segundo script de inicialização

description "consumer script as a service - q9 local queue"

author "mt dev team"

stop on stopping worker-localhost

instance $N

# Automatically Respawn:

respawn

respawn limit 70 5

pre-start script

# script to run before restart - notify or logging script

/bin/sh /root/consumer_restart_log.sh localhost pre-start

end script

script

exec /usr/bin/php /root/tracking/consumer.php localhost $N >>/var/log/aws_consumer_output.log 2>&1

end script

post-start script

# script to run before restart - notify or logging script

/bin/sh /root/consumer_restart_log.sh localhost post-start

end script

Script de versão do Systemd

Description "Consumer script as a service "
author "mt dev"
Conflicts=worker-localhost
