I'm a Linux noob, but have been working with JBoss for a while now on windows. I am trying to follow JBoss's doc on getting the server to run as a service. I am attempting to create a user for this daemon. I believe I have it correct, yet when I attemp to run the service script I get the following:

[root@localhost opt]# /opt/jboss-4.0.1sp1/bin/jboss_init_redhat.sh start
CMD_START = cd /opt/jboss-4.0.1sp1/bin; /opt/jboss-4.0.1sp1/bin/run.sh -c all
su: warning: cannot change directory to /opt/jboss-4.0.1sp1/bin: Permission denied
This account is currently not available.

My thought is that this has something to do with the jbossd user account that I created.

From etc/passwd:
jbossd:x:501:3:JBoss Server:/opt/jboss-4.0.1sp1/bin:/sbin/nologin

Thanks,

What are the permissions on /opt/jboss-4.0.1sp1/bin -- you can do "ls -ld /opt/jboss-4.0.1sp1/bin" (no quotes) to see them.

Thanks for the quick reply. I have been messing with chown and chmod on these dirs with -R. Here's the latest:

drwxr-x--- 2 jbossd root 4096 Apr 7 17:30 /opt/jboss-4.0.1sp1/bin

I figured out that my jboss user was the problem. Now, however I still can't get JBoss started. I keep getting:

[root@localhost init.d]# service jbossd start
CMD_START = cd /usr/local/jboss-4.0.1sp1/bin; /usr/local/jboss-4.0.1sp1/bin/run.sh -c all

That's all. Nothing starts. Just this output.

Thanks

Normally when daemons start they don't print any sort of messages. You can do ps aux and look for the JBoss process to see if it's running. You can use netstat too to make sure it's listening on the correct port. If it's not, you should probably look at the logfiles the application generates. There may also be a verbose output option you can start it with that might give a better clue about the problem -- you'll have to consult the documentation.

Unfortunately, there is little documentation other than the script provided by JBoss. I've done quite a bit of googling on this topic with little results. ps aux does not show it running. netstat does not show it listening. The JBoss logs do not seem to have been touched. I don't think it's doing anything.

The output is coming from the JBoss start up file, but that seems to be all it's doing.

Below is the script provided by JBoss with my alterations:

Code:

#!/bin/sh

#

# JBoss Control Script

#

# chkconfig: 3 80 20

# description: JBoss EJB Container

# 

# To use this script

# run it as root - it will switch to the specified user

# It loses all console output - use the log.

#

# Here is a little (and extremely primitive) 

# startup/shutdown script for RedHat systems. It assumes 

# that JBoss lives in /usr/local/jboss, it's run by user 

# 'jboss' and JDK binaries are in /usr/local/jdk/bin. All 

# this can be changed in the script itself. 

# Bojan 

#

# Either amend this script for your requirements

# or just ensure that the following variables are set correctly 

# before calling the script



# [ #420297 ] JBoss startup/shutdown for RedHat



#define where jboss is - this is the directory containing directories log, bin, conf etc

JBOSS_HOME=${JBOSS_HOME:-"/usr/local/jboss-4.0.1sp1"}



#make java is on your path

JAVAPTH=${JAVAPTH:-"/usr/java/jdk1.5.0_02/bin"}



#define the classpath for the shutdown class

JBOSSCP=${JBOSSCP:-"$JBOSS_HOME/bin/shutdown.jar:$JBOSS_HOME/client/jnet.jar"}



#define the script to use to start jboss

JBOSSSH=${JBOSSSH:-"$JBOSS_HOME/bin/run.sh -c all"}



if [ -n "$JBOSS_CONSOLE" -a ! -d "$JBOSS_CONSOLE" ]; then

  # ensure the file exists

  touch $JBOSS_CONSOLE

fi



if [ -n "$JBOSS_CONSOLE" -a ! -f "$JBOSS_CONSOLE" ]; then

  echo "WARNING: location for saving console log invalid: $JBOSS_CONSOLE"

  echo "WARNING: ignoring it and using /dev/null"

  JBOSS_CONSOLE="/dev/null"

fi



#define what will be done with the console log

JBOSS_CONSOLE=${JBOSS_CONSOLE:-"/dev/null"}



#define the user under which jboss will run, or use RUNASIS to run as the current user

JBOSSUS=${JBOSSUS:-"jbossd"}



CMD_START="cd $JBOSS_HOME/bin; $JBOSSSH" 

CMD_STOP="java -classpath $JBOSSCP org.jboss.Shutdown --shutdown"



if [ "$JBOSSUS" = "RUNASIS" ]; then

  SUBIT=""

else

  SUBIT="su - $JBOSSUS -c "

fi



if [ -z "`echo $PATH | grep $JAVAPTH`" ]; then

  export PATH=$PATH:$JAVAPTH

fi



if [ ! -d "$JBOSS_HOME" ]; then

  echo JBOSS_HOME does not exist as a valid directory : $JBOSS_HOME

  exit 1

fi





echo CMD_START = $CMD_START





case "$1" in

start)

    cd $JBOSS_HOME/bin

    if [ -z "$SUBIT" ]; then

        eval $CMD_START >${JBOSS_CONSOLE} 2>&1 &

    else

        $SUBIT "$CMD_START >${JBOSS_CONSOLE} 2>&1 &" 

    fi

    ;;

stop)

    if [ -z "$SUBIT" ]; then

        $CMD_STOP

    else

        $SUBIT "$CMD_STOP"

    fi 

    ;;

restart)

    $0 stop

    $0 start

    ;;

*)

    echo "usage: $0 (start|stop|restart|help)"

I had the same problem.

The solution to me was to change this:

Code:

JBOSSSH=${JBOSSSH:-"$JBOSS_HOME/bin/run.sh -c all"}

to this:

Code:

JBOSSSH=${JBOSSSH:-"$JBOSS_HOME/bin/run.sh"}

As I have only the default server installed (via the JBoss installer.jar).

-->I figured out that my jboss user was the problem. Now, however I still can't get JBoss started. I keep getting:

I am having the same problem "This account is not currently available". Can you explain what was actually done to fix the jboss user on your system?

Hi Guys,

I have got mine working. - CENTOS 4.4, jdk.1.5.0_08, jboss-4.0.4.GA

Simplied answer is:

I installed jboss in /opt ie /opt/jboss-4.0.4.GA

Copy the jboss_init_redhat.sh as jboss in init.d
# cp /opt/jboss-4.0.4.GA/bin/jboss_init_redhat.sh /etc/init.d/jboss

Code:

Change the following lines in the jboss

#define where jboss is - this is the directory containing directories log, bin, conf etc

JBOSS_HOME=${JBOSS_HOME:-"/opt/jboss-4.0.4.GA"}

                          ~~~~~~~~~~~~~~~~~~~



#make java is on your path

JAVAPTH=${JAVAPTH:-"/usr/java/jdk.1.5.0_08"}

                    ~~~~~~~~~~~~~~~~~~~~~~



#define the script to use to start jboss

JBOSSSH=${JBOSSSH:-"$JBOSS_HOME/bin/run.sh"}

                                          ~~~~~~~~~~~~



#define the user under which jboss will run, or use RUNASIS to run as the current user

JBOSSUS=${JBOSSUS:-"root"}

                    ~~~~



And copied the start bit as status also. See below. Then SAVE File.



case "$1" in

start)

    cd $JBOSS_HOME/bin

    if [ -z "$SUBIT" ]; then

        eval $CMD_START >${JBOSS_CONSOLE} 2>&1 &

    else

        $SUBIT "$CMD_START >${JBOSS_CONSOLE} 2>&1 &" 

    fi

    ;;

status)

    cd $JBOSS_HOME/bin

    if [ -z "$SUBIT" ]; then

        eval $CMD_START >${JBOSS_CONSOLE} 2>&1 &

    else

        $SUBIT "$CMD_START >${JBOSS_CONSOLE} 2>&1 &" 

    fi

    ;;

stop)

    if [ -z "$SUBIT" ]; then

        $CMD_STOP

    else

        $SUBIT "$CMD_STOP"

    fi 

    ;;

restart)

    $0 stop

    $0 start

    ;;

*)

    echo "usage: $0 (start|stop|restart|help)"

esac

On the menu,
goto Server Settings->Services, enter root password.
goto Actions->Add Service
enter jboss
click on the checkbox for jboss, save.
Reboot the server.

Give enough time for the jboss to complete it's startup and test.

Enjoy

Please let me know if it works for you.
