Howto

JDownloader is since many years my favorite download manager. He has indeed many positive points:

• supports an impressive number of hosts (Uptobox, Rapidshare, Youtube, ... 1file.)
• Java-based platform
• support for multi-site premium subscriptions such alldebrid.com
• supporting different types of captchas
• controllable via a dedicated Android app or better a simple browser (my.jdownloader.org)
• Free and open-source

Only an account is needed from my.jdownloader.org to use Jdownloader2

prepare and download

• You need first to install java

yum install java-1.8.0-openjdk

• you need to make a folder

 mkdir /usr/share/JD2

• you need to download the java file

cd /usr/share/JD2
wget http://installer.jdownloader.org/JDownloader.jar

set JD

here you need an account with your password from http://my.jdownloader.org/

• now you can launch the java software

java -Djava.awt.headless=true -jar /usr/share/JD2/JDownloader.jar

JD2 will ask to update, answer yes (y), then it need to restart

• launch again the java software

 java -Djava.awt.headless=true -jar /usr/share/JD2/JDownloader.jar

here it will ask your jdownloader account.

	Note:
	at my first start, the former instance was not closed properly , I found these warnings when I launched JD2 the second time -> existing jD instance found! -> Send parameters to existing jD instance and exit: [--focus] in fact you have to close JD ps aux |grep JD find the pid, for example here kill -9 7336

start at boot time

now when you launch the command above your JD instance is able to run. we have to create an init script to run JD at the boot time

• create the jdownloader system user

/sbin/e-smith/create-system-user jdownloader 810 "Jdownloader server" /usr/share/JD2/ /bin/false

• set good ownership

chown jdownloader:jdownloader /usr/share/JD2/ -R

• create the db entry

db configuration set jdownloader service status enabled

• create the initscript

vim /etc/rc.d/init.d/jdownloader

and paste this

#!/bin/sh

  if [ -f $PIDFILE ]; then
      PID=$(cat $PIDFILE)
          if [ -z "$(ps axf | grep ${PID} | grep -v grep)" ]; then
              printf "%s\n" "The process appears to be dead but pidfile still exists"
          else
              echo "Running, the PID is $PID"
          fi
  else
      printf "%s\n" "Service not running"
  fi
}


case "$1" in

  uninstall

  echo "Usage: $0 {start|stop|status|restart|uninstall}"
esac

we need to get that script executable

chown u+x /etc/rc.d/init.d/jdownloader

and set the time when we want it starts

chkconfig --add jdownloader
ln -s  /etc/rc.d/init.d/e-smith-service S90jdownloader
