Logging in an init.d script

hello to all,

i want to start the EJB app server from an init.d script.

It looks like:


#!/bin/sh
#
# Startup script for JBOSS,
#
# chkconfig: 2345 95 15
# description: JBoss is an EJB Server
# processname: jboss
# pidfile: /var/run/jboss.pid
# config: /opt/jboss-3.2.2RC2
# logfile: /opt/jboss-3.2.2RC2/log/server.log
#
# version 1.0 -
# version 1.1 - kjenks - Start Tomcat, too
#

# Source function library.
.. /etc/rc.d/init.d/functions

# Java dir
export JAVA_HOME=/usr/java/jdk1.3.1_08

export JBOSS_HOME=/opt/jboss-3.2.2RC2

export PATH=$PATH:$JBOSS_HOME/bin:$JAVA_HOME/bin:$JAVA_HOME/jre/bin

# I f YOU NEED SPECIAL CLASSES IN YOUR CLASSPATH
# AT STARTUP, ADD THEM TO YOUR CLASSPATH HERE
# export CLASSPATH=

RETVAL=0

# See how we were called.

case "$1" in
start)
cd $JBOSS_HOME/bin
echo -n "Starting jboss daemon: "
daemon $JBOSS_HOME/bin/run.sh start
RETVAL=$?
echo
[ $RETVAL -eq 0 ] && touch /var/lock/subsys/jboss
;;
stop)
echo -n "Stopping jboss daemon: "
killproc jboss
RETVAL=$?
echo
[ $RETVAL -eq 0 ] && rm -f
/var/lock/subsys/jboss
;;
restart)
echo -n "Restarting jboss daemon: "
$0 stop
sleep 2
$0 start
;;
esac


After do a . /init.d/jboss start.
>Starting daemon jboss

nothing else happens.
when i start the run.sh from the shell it prints a lot of message on
stdin and everything works well. So I tried to use a logfile to see
whats wrong.

I tried to call: daemon $JBOSS_HOME/bin/run.sh start >/var/log/jboss.log
2>&1

But this does not work. The logfile is empty.

How can I do a logging? How does 'daemon' work? There is no man page.

THANKS A LOT!!

"daemon" is not a binary executable. It is a bash function defined in
/etc/init.d/functions, which gets sourced in to this script via the line:

# Source function library.
. /etc/rc.d/init.d/functions

If you follow the logic in this function, you'll see that ultimately it
starts the command via the "initlog" command:

if [ -z "$user" ]; then
$nice initlog $INITLOG_ARGS -c "$*"

The $INITLOG_ARGS is set to "-q" if $BOOTUP is set to something other than
"verbose" in /etc/sysconfig/init (I'm just getting this from the scripts on
my system, RH9... your system might be different).

Anyway, if you do a man on initlog you'll see that the -q option means do
*not* print the program's output. Unless you do something to make the
value of $BOOTUP equal to "verbose", the default value for $INITLOG_ARGS is
"-q" so you won't see any messages.

No, it started the daemon. If you do a "ps -eal", I suspect you'll see
JBOSS started. It just suppressed the messages from the run.sh script.
