You need "screen" to do it this way. If you don't have it then get it [1] or use an alternative to this procedure and run a DaemonizedAzureus.

Create User

• Create a user for running Azureus. We called him "azureuser". Replace all azureuser with your desired name!
• The <install-dir> is /home/azureuser/azureus. If you installed it somewhere else then substitute your <install-dir> into the scripts for this one.

Write Startscript

• To make Azureus start at boot, make a script in /home/azureuser/azureus

Create a textfile with the name "azureus_script"

/home/azureuser/azureus/azureus_script contains:

Copy to Clipboard

 #! /bin/sh
 
 #The user that will run Azureus
 AZ_USER=azureus
 
 #Name of the screen-session
 NAME=azureus_screen
 
 #executable files in the following paths that are perhaps needed by the script
 PATH=/bin:/usr/bin:/sbin:/usr/sbin:/home/azureus/bin
 
 #your path to the azureus directory, where Azureus2.jar is located
 DIR=/home/azureuser/azureus
 
 #Description
 DESC="Azureus screen daemon"

       echo "Azureus is already running!"
    else
       echo "Starting $DESC: $NAME"
       su $AZ_USER -c "cd $DIR; screen -dmS $NAME java -jar ./Azureus2.jar --ui=console"
    fi
    ;;
 stop)
    if [[ `su $AZ_USER -c "screen -ls |grep $NAME"` ]]
       then
       echo -n "Stopping $DESC: $NAME"
       su $AZ_USER -c "screen -X quit"
       echo " ... done."
    else
       echo "Coulnd't find a running $DESC"
    fi
    ;;
 restart)
    if [[ `su $AZ_USER -c "screen -ls |grep $NAME"` ]]
        then
       echo -n "Stopping $DESC: $NAME"
       su $AZ_USER -c "screen -X quit"
       echo " ... done."
    else
       echo "Coulnd't find a running $DESC"
    fi
    echo "Starting $DESC: $NAME"
       su $AZ_USER -c "cd $DIR; screen -dmS $NAME java -jar ./Azureus2.jar --ui=console"
    echo " ... done."

       echo "Azureus is RUNNING"

NOTE: Ubuntu uses dash as the low-level script interpreter invoked by 'sh' so this script will not work as-is on those systems. The quickest fix is to just change the first line to

Copy to Clipboard

#! /bin/bash

instead of

Copy to Clipboard

#! /bin/sh

Then chmod the scripts to make it executable

Copy to Clipboard

 chmod a+x azureus_script

Test your script

Start Azureus by typing ./azureus_script start You must be in the directory where your script is. At this point you have to enter the password of the "azureuser"-User twice. (When the script is loaded at startup, you don't have to do that!) Re-attach the virtual console by screen -r azureus_screen You should now see the normal console-ui of azureus. Test also if you are able to connect to your AzureusHTMLWebUI in your Browser. If this happened correctly, detach the azureus_screen again by pressing ctrl-a and then d. The azureus console-ui should now be hidden. Test now your stop-script by typing ./azureus_script stop If Azureus was sucsessfully killed you can't find "java" in your process list typing top except you have another Java programm running. Exit the process list by pressing q

If these tests were successfully, you can go further to the next step.

If your script does not start Azureus try this command from the command prompt within the Azureus directory.

Copy to Clipboard

java -jar ./Azureus2.jar --ui=console

If this command works the PATH in the script may be incomplete or wrong. Replace the value for PATH in the script with the value from the command:

Copy to Clipboard

echo $PATH

Install startscript

NOTE: This procedure will not work on Ubuntu (and could probably seriously mess up your init process) On Ubuntu simply copy the script to "/etc/init.d/" (using root privileges) and run sudo update-rc.d azureus_script default Also, Debian init scripts should have an LSB defined in them, see [2]

Get superuser access su

Copy your script in your runlevel-script directory. In most cases it is /etc/rc.d/

Copy to Clipboard

cp /home/azureuser/azureus/azureus_script /etc/rc.d/

Now create symbolic links in your default runlevel directory. One to start when entering the runlevel and another one to stop azureus tidily when leaving your runlevel, e.g. shutdown your copmuter.

First find out your default runlevel by typing

Copy to Clipboard

 cat /etc/inittab | grep :initdefault:

the number on the line that outputs it is your default runlevel. Symlink the azureus_script into the directory of the default runlevel.

Copy to Clipboard

cd /etc/rc3.d
ln -s /etc/rc.d/azureus_script S99azureus_script

All startscripts in your runlevel folder begin with "S" followed by a number, that gives the start-order. The number 99 makes the "azureus_script" script run after everything else at boot. Now when your machine starts up, the last thing that starts is azureus in console mode with a Web UI enabled.

Now, to stop Azureus tidily when you shutdown your computer, you must also create a symlink for your stop-script.

Copy to Clipboard

ln -s /etc/rc.d/azureus_script K01azureus_script

"K" means stop and the number 01 let quit azureus first, before other processes were killed.

Reboot

Reboot and try to connect to the Web-UI with your browser.
