Motivation
- You have a service that needs to start more than one process
- You want to use Ubuntu Upstart to manage the service
- You want to su to another user when running the service
Example
description "my service name here"
version "1.0"
author "James Cooper"
env PATH=/bin:/usr/bin:/usr/local/bin
env RUNUSER=web
env LOGDIR=/home/$RUNUSER/logs
respawn
start on runlevel [23]
script
mkdir -p $LOGDIR
chown $RUNUSER $LOGDIR
su $RUNUSER -c "/path/to/script1 & echo \$! > $LOGDIR/script1.pid"
exec su $RUNUSER -c "exec /path/to/script2 >> $LOGDIR/stdout.log 2>> $LOGDIR/stderr.log"
end script
pre-stop exec kill `cat $LOGDIR/logs/script1.pid`
Notes
- The pre-stop hook runs first when you stop the service. It kills script1
- Make sure you backslash escape the $!
- No ; after the & that backgrounds script1
