With this guide you can easily install JDownloader 2 (from now on JD2) on your nas Qnap, both version are supported, Arm and Intel!

Premise
This method is "fully" automated, just follow this simple step! This script install also the qpkg for your Qnap, so you can activate and deactivate it through the App Center on your Qnap system. This script is also Auto-Upgradable, so if new version of this script is released, it upgrade itself automatically!
Let's do it!

Requirements

• Nas Qnap!!!
• JRE from the App Center of your Qnap
• Optware or Entware-ng:
  For those who want to use Optware, I suggest this one:
  forum.Qnap.com/viewtopic.php?f=124&t=45769&hilit=ipkg+sl1000+download&start=30#p206927 sl1000
  and the relative fix:
  wiki.qnap.com/wiki/Install_Optware_IPKG#Fix_the_.24PATH_in_.2Fetc.2Fprofile
  For those who want to use Entware-ng, I suggest this one:
  forum.qnap.com/viewtopic.php?f=351&t=116737
• Have an account on my.jdownloader.org
• Have a minimum of familiarity with putty and some basic skills!

Here is the exact process , I recommend you follow it, step to step and you'll be fine

Installation

1. Download this script:
   dropbox.com/s/iaafkg38waduo4a/JD2_Qnap_installer.sh?dl=0
   WARNING: the script won't work out-of-the-box for older QNAP devices and needs manual changes, see
   https://board.jdownloader.org/showpo...&postcount=449
   Alternative version (1.38) of the script for older QNAP nas devices (modified to be hosted on our server):
   installer.jdownloader.org/3rdpartyqnap/JD2_Qnap_installer.sh
   Is the installation script, copy it on your nas, I suggest to copy it on the Public folder
2. Access through ssh at your Nas with Putty and go to the directory where you copied the installer script, in this case:
   

   cd `/sbin/getcfg Public path -f /etc/config/smb.conf`

3. Now you've to make it executable, so:
   

   chmod +x JD2_Qnap_installer.sh

4. Now you've to execute it, so:
   

   ./JD2_Qnap_installer.sh

5. Don't care about this error:
   

   Link service start/stop script: JDownloader2.sh
   Set QPKG information in /etc/config/qpkg.conf
    Checking for /opt...  Found!
   Unable to find JD2 in the folder: /share/CACHEDEV1_DATA/.qpkg/JDownloader2/JD2.

   It's normal, because JD2 is not yet installed!
6. Now, you've only to wait until you'll see
   

   |---------------------------Headless Information-------------------------------
   |       New Update available
   |       A new Update is available. Do you want to download it now?
   |       Enter y -> Download now
   |       Enter n -> Later
   y

   Obviously you have to insert y like me
7. Now, you've to wait until you'll see this request
   

   |---------------------------Headless Information-------------------------------
   |       MyJDownloader Setup
   |       Your 'My JDownloader' logins are not correct.
   |       Please check username/email and password!
   |       Enter y -> Enter Logins
   |       Enter n -> Exit JDownloader
   y
   |       Please Enter your MyJDownloader Email:
   ***************
   |       Please Enter your MyJDownloader Password:
   ***************

   This is an important step, you've to insert your log-in credentials to connect JD2 to the web service!
8. Now, you've only to wait until you'll see
   

   set  CONNECTED

   Now, manually, you've to do this combination of key, on your keyboard:
   

   CTRL+C

9. Done, remain just the last information that indicate that all is ok. This also make you a request, so press any key and then you can close the putty windows!
   

   ==========================================================================================
   All done!!! Remember to log-in to https://my.jdownloader.org/login.html and configure JD2!
   ==========================================================================================
   Ok, now press any key to continue, then you can terminate this ssh session. Have a Good Download!!!

Configuration

1. From now on all the configurations are via web, so log-in on my.jdownloader.org and go to the JD2 (Settings), then (Advanced Settings) and for 1st change the (Default Download Folder), remember that you've to input a path like that /share/Download, or other
   Important note that will be valid only from 1.31 version: If you don't want, don't know what is a path or simply if you skip this passage, all your download will be put on the default Qnap Download folder! So you need to change it only if you really need to change it!
2. Always from the (Advanced Settings) you've to reset the field (Browser Command Line)
3. If you don't have an account on 9kw.eu/register.html service make one on it, it's a captchas solver. The best thinks about it, is that if you don't want to buy some captcha credits, you can partecipate, solving some captchas and earn captcha credits!
4. Through the service my.jdownloader there is the 3 major mobile apps to controll JD2, just go at Mobile Apps! If you can't see it this's the links
   Android App:
   play.google.com/store/apps/details?id=org.appwork.myjdandroid
   Apple App:
   itunes.apple.com/de/app/jdanywhere/id683222457
   Windows phone App:
   windowsphone.com/de-de/store/app/file-recon/e40c41d0-3c94-4ed6-9fe8-66d4547a8ffe
5. Enjoy your new JD2 for Qnap :D

Hi Chryses,
nice job! I didn't test it yet, but it looks very promising.
Did you use the QDK to build the qpkg? If yes, where did you get?
I also wanted to have a look at it (just out of curiosity), but I couldn't get the QDK anywhere (all links on the QNAP page are not available anymore). The App Center of my TS-219P II doesn't contain it neither.
Is it only available for certain models?

Update: I found it myself. There is a valid link for QDK 2.2.4 in the quick start guide PDF.

Many tnx, sorry for the delay!
2.2.4? I'm still stuck at 2.2.2, that actually have some bug!

Yep is a mix of a qpkg and an external script that install all!

JD2 unfortunately does not work properly on QNAP ( my 453mini qts 4.2 )
after installation is all ok, but after a reboot does not work, you can start it manually but you can not connect to it through the site my.jdownloader.org.
Java works well, so i don't wny idea how fixit it.

[Jiaz]

I can help via Teamviewer if you want, contact us via support@jdownloader.org

When it works one, it should work always. After rebooting not working -> guess its simple setup issue

The script uses disown, but I think is not available on all system, so ... what do you think is better Jiaz, screen or disown?

@yabba235
can you write to me the output of this command?

disown

which screen

[Jiaz]

you dont need disown or screen
you can also use
su -c "command &" user
to start in background,would change it into that

I don't know why but, seems that
1. by default seems that all programs installed via qpkg run with admin
2. there is no sudo so no su command availabe, must be installed via ipkg
3. not all version of qnap have disown

I don't know why but seems that some peoples have some trouble to start jd2, ok during the installation phase if you close the ssh session and jd2 is not on background, but in theory if you go to the cpannel and start it again must works! But seems that is not true, and is strange.

So:
I tried to use screen, after a jd2 update screen wont works
Not all qnap have disown!

I've now 2 way
1. installing sudo via ipkg and run your command
2. installing coreutils via ipkg and run nohup

Qpkg updated to 1.32.
Introduced a double check on the pid file
Disabled disown command

Great work, love this alot...
I only have one issue... every time i close the ssh connection, jdownloader stops working...

Any ideas?

Hi, tnx.

First of all check that have the latest version 1.32

The ssh connection is only for the installing purpose, so you install jd2 via ssh and close the ssh session, if jd2 stop you need to go to the qnap app center and disable JDownloader2, the you can re-enable it, always from qnap app center

[Jiaz]

I helped him via teamviewer and installed coreutils -> to provide nohup and updated script to use nohup

Updated to 1.33
If launched via ssh connection, jd2 starts with screen and inform the user

@Chryses
thank you for the guide. Everything works perfectly.
Only thing i see is that my Qnap dont go in standby, do you think its jdownloader?
I also do a firmware upgrade on the Qnap.

[Jiaz]

This will be fixed by an update for JDownloader. We will fix this issue as soon as possible

Tnx. I think that is a "common" problem when you use programs that need to be always on activity and/or online. In my opinion this is better for the hd life, less start/stop cycle I mean.

Any news?
There are some updates in last time, but problem is stil here.
If i turn off jdownloader in qnap, the harddisk spin down.

[Jiaz]

Its not the activity, it is the update check touching a file on disk.

Thank you, hope a update will solve this little problem.

I think i can update via Jdownloader Androis app, i see there is something like "update jdwonloader". No need to change something on the Qnap?

[Jiaz]

nothing to change jd will update itself and remote apps will inform about pending update

Thanks.

Umm thats the same version I have (4.2) and I got jDownloader working!. I followed the tutorial on this forum and it went smoothly!

Hi all,
I installed jdownlader on my QNAP TS-212p as per the description above. Everything worked fine, I got the "set CONNECTED" and "All done!!!.." messages. However, on my jdownloader account, I still get the message "No connected JDownloader found".
How can I establish the connection again?

Hey Guys

This would be the solution to all my problems

I tried to follow the described steps but keep getting the following error while installing JDownloader:

[/share/HDA_DATA/Public] # sh JD2_Qnap_installer.sh

=============================================================
JDownloader2 QPKG Installer script
=============================================================

Checking for /opt... Found!
Checking for Java... Found... exporting variables
Checking for Java executable... Java does not run correctly. Please test the Java environment and try again.


Can somebody tell my what I was doing wrong?

NAS: TS-109
Firmware: 3.3.3 Build 1003T
JRE:
Version: 6.0.22
Installation Path: /share/HDA_DATA/.qpkg/JRE




I googled now what the problem could be, but i am stock, everything looks properly set up ....

Thanks for the support guys!

Got an error while trying to install it.

Looks like the update file is gone.

The link leads to file not found. Can anyone help? Thanks in advance

[sultanbrunei]

everytime I install jdownloader through putty,
it always stuck in "Update message: check for updates".

Therefore I could never get to "set: connected".
Anyone knows how can I fix this?

[Jiaz]

That's not stuck, that's normal and okay.
It is important to start it first time with
java -jar JDownloader.jar -norestart
so you can enter your MyJDownloader logins on console.

I have folled the steps except for the location of the JDownloader2 QPKG Installer script.

In my case this is in "cd '/sbin/getcfg /share/CACHEDEV1_DATA/Multimedia/Downloads/JDownloader2/Config path -f /etc/config/smb.conf'"

However, when I try to execute ./JD2_Qnap_installer.sh, I'm faced with

"=============================================================
JDownloader2 QPKG Installer script
=============================================================

The Public share not found.
[/share/CACHEDEV1_DATA/Multimedia/Downloads/JDownloader2/Config] #
#"

Any ideas?

[tt_1111]

Die Installation läuft bis 'Upgrade progress: 100%' – ca. 25 Zeilen nach Eingabe der Login Credentials. Danach passiert in der SSH-Session gar nichts mehr; ich habe vorsichtshalber fast eine Stunde gewartet.

Im QNAP App-Center (TS-332x, Arm Cortex 57 CPU) taucht der JDownloader auf und lässt sich auch über my.jdownloader.org verwalten.

Wenn ich die SSH-Session dann schließe, verschwindet allerdings auch der JDownloader wieder aus dem Dashboard auf my.jdownloader.org. Stoppen und Neustarten der QNAP-App (JDL) hilft nicht.

Zusammengefasst also: Der JDL wird auf dem QNAP NAS nur solange bereitgestellt, wie die SSH-Session noch offen ist. Danach 'isser wech'.

Mache ich etwas falsch? Oder ist es ein spezielles Problem mit der Arm 57 x64 CPU?

Bin für jeden Tipp dankbar!

[Jiaz]

You're welcome!

Hello Chryses,

it seems that there is something change in the actual QNAP Firmware 4.2.0(20150819). I now it is Beta status at the moment, but it will be final soon.

I get the attached Warning message, that the JDownloader2 Apps will no longer be supported. But it seems to work fine.

Maybe you want to look into it.

Best regards

Maybe in final relase of QTS 4.2 JD2 stop working, who knows that ?
For now work fine so I'm happy
Reg

[Jiaz]

I guess its a simple version variable in package that defines what qnap firmware are supported

[tarkett]

For more information about the QNAP changes

_**External links are only visible to Support Staff**
I hope it is okay, that I post the link.

Edit: Here is the interest part about this change. I think Optware is the problem.

Hi,

For Your Information 

After  exchange with QNAP ... please consider following message from App.  Center ... saying that some QPKG are now unsupported as an error (Bug)

An  error occurs in the test ... that ONLY compare to a whitelist of QNAP's  official application ... and not separate applications by origin ...

SO the warning is correct for QNAP's list NOR (or perhaps) for other QPKG

Change impacting App. ... that will don't work or not :
ALL  using Optware (perhaps) ... please contact dev. or use other version  without ipkg / Optware requested ... move to QNAPware / Entware
PHP application due to upgrade of PHP : PHP Version => 5.5.27
Mysql application  and MariaDB application due to replacement of mysql by MariaDB : Ver 15.1 Distrib 5.5.44-MariaDB

This will be corrected in next update with a more clear message AND special notes in "release notes".
Philippe.

[Jiaz]

yes it is too sad the board is not open for read without an account

Now JD2 requires optware fo install, so maybe is time to change it to qnapware requires ?
Optware is obsolete and replaced with qnapware.
If final compilation qts 4.2 will not allow to run optware JD2 may not be possible to install on qnap machine :(
