Shutdown Linux nouGUI script?

Andreas

Is it possible to stop aware using a script in linux?
Like the one used to start aware under nogui linux: startAwareIMNoGUI.sh ?

No. You need to kill all "java" processes in memory.

Is it safe to use this script and then shut down it by killing all java and again starting it in terms of errors that can lead it in working application?

Or is it safer to work under GUI?

Sergej

Is it safer in terms of errors to run it as a service?

Sergej

what the best and most correct way to stop startAwareIMNoGUI.sh?

With KDE i am having encoding issue that makes impossible opening files with cyrilic names.

If you have GUI always shutdown by closing the Control Panel. If you don't have GUI kill java processes - this should be safe enough

I've been playing around with the startup & shutdown on Linux without GUI in order to be able to start/stop Aware IM easily.

I've managed to alter the startAwareIMNoGUI.sh script so:

it logs all output to ../log/console.log en rotates any previous console.log
writes a awareim.pid-file to hold the parent PID
I created also a stopAwareIMNoGUI.sh script that reads the parent PID (Aware server) and kills the child processed (Tomcat & JBoss)

For startAwareIMNoGUI.sh: replace in the file shipped by Aware the last line with this snippet:

#rename previous console.log-file
echo "archive previous logfile"
mv ../log/console.log "../log/console_`date +%Y%m%d-%H%M%S`.log"
echo "log current output to ../log/console.log"
$JDK_HOME/bin/java -Xmx192m -Xms20m -Djava.awt.headless=true -cp $CLASSPATH com.bas.basserver.bsmanager.NonGUIServerMonitorCallback &>> ../log/console.log &
echo $! > awareim.pid
echo "Aware IM started (PID:$!)."

the stopAwareIMNoGUI.sh script:

#!/bin/sh
echo "Kill complete Aware IM process-tree (Aware IM server, Tomcat, JBoss)"
parentPID=$(cat awareim.pid)
if [ -n "$parentPID" ]; then
	childPIDs=`ps -o pid --no-headers --ppid ${parentPID}`
	for child in $childPIDs
	do
		echo " - kill child process $child"
		kill -9 $child
	done
	echo "- kill main process ($parentPID)"
	kill $parentPID
	rm ./awareim.pid
	echo "KILLING DONE."
	echo "killing Aware IM by ./stopAwareIMNoGUI.sh" >> ../log/console.log
else
	echo "ERROR: could not stop Aware IM (Aware IM is not running, or is running in GUI modus)"
fi

In addition to my previous post, I've created a daemon script, so Aware can start on boot

conditions: tested on Linux CentOS 6.2 - Aware IM installed on /usr/aware - change this path were needed below

1. create a new file /etc/init.d/aware with

#!/bin/sh
#chkconfig: 2345 20 80
#description: Starts and stops the Aware IM daemon (includes Aware IM server, JBoss and Tomcat)
#processname: aware
     

aware=/usr/aware
startup=$aware/bin/startAwareIMNoGUI.sh
shutdown=$aware/bin/stopAwareIMNoGUI.sh
     

start() {
  echo -n $"Starting Aware IM service: "/bin/su - -s /bin/sh root -c "cd /usr/aware/bin; $startup"
  echo $?
}
     

stop() {
  echo -n $"Stopping Aware IM service: "/bin/su - -s /bin/sh root -c "cd /usr/aware/bin; $shutdown"
  echo $?
}
     

restart() {
  stop
  start
}
     

status() {
  ps aux | egrep "com.bas.basserver.bsmanager.NonGUIServerMonitorCallback|org.jboss.Main|org.apache.catalina.startup.Bootstrap" | grep -v "com.bas.basserver.bsmanager.NonGUIServerMonitorCallback|org.jboss.Main|org.apache.catalina.startup.Bootstrap"
}
     

# Handle the different input options
case "$1" in
start)
  start
  ;;
stop)
  stop
  ;;
status)
  status
  ;;
restart)
  restart
  ;;
*)
  echo $"Usage: $0 {start|stop|restart|status}"
  exit 1
esac
     

exit 0

2. Set this aware daemon script as executable

chmod +x /etc/init.d/aware

3. Testing the aware daemon script

./aware start
./aware stop
./aware status

4. Add aware as service for all runlevels

chkconfig --add aware
chkconfig aware on

5. From now on Aware will start up on booting and you can use these commands

service aware start
service aware status
service aware stop
