Upstart script for Ejabberd

ejabberd.conf

# Ubuntu upstart file at /etc/init/ejabberd.conf

respawn
respawn limit 20 5

start on runlevel [2345]
stop on runlevel [06]

script
    exec start-stop-daemon --start --name ejabberd  --user ejabberd --chuid ejabberd --exec /usr/local/sbin/ejabberdctl -- start
end script

pre-stop script
    exec start-stop-daemon --stop --oknodo --signal QUIT --user ejabberd --chuid ejabberd --exec /usr/lib/erlang/erts-5.10.1/bin/beam.smp
end script

to make this work with Upstart, an additional change is to modify ejabberdctl start function from this:

start ()
{
    checknodenameusage
    [ "$?" -eq 0 ] && echo "\nERROR: The node '$ERLANG_NODE' is already running." && return 1

    $EXEC_CMD "$ERL \
      $NAME $ERLANG_NODE \
      -noinput -detached \
      -pa $EJABBERD_EBIN_PATH \
      -mnesia dir \"\\\"$SPOOLDIR\\\"\" \
      $KERNEL_OPTS \
      -s ejabberd \
      -sasl sasl_error_logger \\{file,\\\"$SASL_LOG_PATH\\\"\\} \
      $ERLANG_OPTS $ARGS \"$@\""
}

to this:

start ()
{
    checknodenameusage
    [ "$?" -eq 0 ] && echo "\nERROR: The node '$ERLANG_NODE' is already running." && return 1

    $EXEC_CMD "$ERL \
      $NAME $ERLANG_NODE \
      -noinput \
      -pa $EJABBERD_EBIN_PATH \
      -mnesia dir \"\\\"$SPOOLDIR\\\"\" \
      $KERNEL_OPTS \
      -s ejabberd \
      -sasl sasl_error_logger \\{file,\\\"$SASL_LOG_PATH\\\"\\} \
      $ERLANG_OPTS $ARGS \"$@\""
}
