Installing JBoss AS 6.0 Final on Ubuntu Server 11.04 for mere mortals

Installing JBoss Application Server isn’t easy – it’s big, clunky and documented by sexually frustrated neckbeard types who write like wannabe MIT professors. As a predominantly PHP-based developer, and Ubuntu user (i.e. one of the “unwashed masses”) this can be a bit daunting, if not outright fucking frustrating, especially because JBoss-types snob us Ubuntu types.

For this reason, I’ve compiled a guide on installing JBoss on Ubuntu Server 11.04 (this guide works fine for the desktop version of Ubuntu as well).


First, we need to create a user that will run JBoss on your Ubuntu server – lots of services do this, like Apache is usually ran as a user called “www-data”.

$ sudo useradd -m -d /usr/local/jboss -s /bin/sh jboss

Now we need to install a Java Development Kit. For the purposes of this tutorial I’m using the Sun one, but there’s a bunch of others that exist because some other neckbeard types don’t like the Sun license.

The Sun JDK package is sun-java6-jdk, but to get access to it through apt, you have to uncomment the ‘partner’ repositories in /etc/apt/sources.list, so open that file up in nano or something and uncomment the following two lines (they’ll be near the bottom)

deb natty partner
deb-src natty partner

Once that’s done, you’ll need to update the GPG signatures on the repositories and update apt.

$ sudo apt-key adv --keyserver --recv 3E5C1192 && sudo apt-get update

Now you can finally install the Sun JDK

sudo apt-get install sun-java6-jdk

It probably wants to restart, so you’d better let it.


Now we need to download JBoss – sounds easy, but there’s so many different download links on the JBoss download page that I could forgive a person for not knowing. You want to click the one that says 6.0.0.Final, and once you’ve done that, download the one that looks like The easiest way to do this is to just fetch it with the command

$ wget -O ~/

Now we can unzip it to the place JBoss recommends – /usr/local

$ sudo unzip ~/ -d /usr/local/

This will make the directory /usr/local/jboss-6.0.0.Final, which we need to do two things to: first, set its owner as that jboss user we made earlier

$ sudo chown -R jboss:jboss /usr/local/jboss-6.0.0.Final/

Second, create a simlink to it from where JBoss will expect it to be – /usr/local/jboss (deleting the actual directory first – thanks Ken)

$ sudo rm -rf /usr/local/jboss
$ sudo ln -s /usr/local/jboss-6.0.0.Final /usr/local/jboss

This is just another “best practice” thing to do, and can make upgrading/downgrading less of a hassle in the future.

Setting up service scripts

JBoss comes out of the box with service scripts (those things that live in /etc/init.d) for RedHat, SUSE, CentOS, Solaris, HPUX (whatever the fuck that is), but not Ubuntu – another serious case of neckbeard snobbery. So let’s make one.

First, copy the RedHat script and rename it ‘ubuntu’

$ sudo cp /usr/local/jboss/bin/ /usr/local/jboss/bin/

Now open it up in your favourite text editor (I use nano – fuck you neckbeards), and make the following amendments

  • Change the JAVAPTH line so it points to just /usr/bin


  • Between the JBOSS_CONF and JBOSS_BIND_ADDR lines, add a definition for JBOSS_HOST, because if you don’t JBoss “binds” to the loopback interface and you can only access it from the server itself – nice one neckbeards. You can make this line either lots of zeros, which is like a wild-card, or a specific IP address if you only want it to be accessible from a particular network interface. Personally I believe this sort of shit is the responsibility of your firewall, and consider this sort of config totally redundant.


Once you’ve saved it, we can now make a simlink to it from /etc/init.d

$ sudo ln -s /usr/local/jboss/bin/ /etc/init.d/jboss

Finally, let’s add it to the system startup services, so it will run at boot (like Apache and all those kind of services do)

$ sudo update-rc.d jboss defaults

Now you can actually try firing the bitch up now by running the following command

$ sudo /etc/init.d/jboss start

On my crappy VM it takes about a minute, and it doesn’t tell you when it’s “done”, so you can follow it’s progress by seeing which ports it’s opened with the following command

$ netstat -al

You’re looking for one with :http-alt in the line. As soon as that’s up, you’re good to go.

Dell PERC 6i “Fast Initialize” – how to restore

TL;DR: Make a BartPE boot disc, with Dell RAID drivers and EASEUS Free Partition recovery. Undelete those partitions LIKE A BOSS.

Yesterday at 6PM, while installing a new drive in our Dell PowerEdge 2900, I accidentally “fast initialized” the system drive in the machine.

Yes, this is pretty much as stupid as it sounds. When you install a new drive (the guide I used), you basically turn the machine off, remove a drive bay cover panel, insert the new drive (wrapped in a $45 caddy and a $48 interposer – woo Dell!), boot up the machine, press Ctrl-R/M to get through to the RAID config, create a new “virtual disk”, add the just installed “physical drive” to it, and finally initialize the new virtual disk. Unfortunately, the Dell RAID config software is a little unclear, when you finish creating the new virtual disk, it asks you if you want to initialise it, then takes you to a selection screen – I just picked the first one. Big mistake! In 1/3rd of a second I’d effectively deleted the first and last 8MB of our main server’s boot disk, which includes the MBR, bootsector, partition map, etc, etc… You know that “oh fuck” feeling you get when you’ve done something horribly wrong?

Anyway, here’s how I restored it.

First, I figured out what a “fast initialize” actually is. An article on the Dell support website says:

A fast initialization on a virtual disk overwrites the first and last 8 MB of the virtual disk, clearing any boot records or partition information.

Great, so the data is still all there, it’s just missing the MBR and partition stuff.

So next I needed a boot CD so I could run some recovery software on the machine. At first I considered using an Ubuntu LiveCD, GParted and GNU DDRescue, because there’s a great recovery guide on the Ubuntu community site, but I was worried that I’d have to mess around with drivers to get Ubuntu to recognise the Dell’s PERC 6i RAID array.

So I settled on BartPE, which is basically a modifiable version of the Windows Preinstalled Environment akin to the Linux LiveCD concept. BartPE CDs are created using the PE Builder, which allows you to customise drivers and software, so I added the Dell PERC 6 drivers (downloadable from the Dell website) using this guide.

Now I needed a partition recovery bit of software. Unfortunately I actually tried 3 before I found one that worked just right. I first tried’s GetDataBack for NTFS which can be added as a plugin to Bart PE, and after a 1h40m scan I realised to my horror that GetDataBack is just a file recovery tool – it doesn’t recover partition information at all. It did find all of the data on the drive, but recovering this way would have meant an enormous copy/format/paste shuffle. No good.

So next I tried Active@ Partition Recovery, whose website is really dodgy looking. I added it to yet another BartPE disc by adding its Windows executable in PE Builder as a custom directory (the DOS version of Active@ PR does not work with BartPE’s command prompt, as it is 16-bit native). I had to open a command prompt once this BartPE disc had booted on the server and navigate to the executable to run it, but it did work. After another 1h10m “fast scan”, Active@ had detected one of the two partitions on the drive, and seemingly not the other. Fortunately it was the boot drive, so I restored it.

Now all I had to do was mark the drive as active and fix its MBR, which I did by booting from a Windows 7 disc, running the recovery console and running DISKPART, then BOOTSECT /nt52 C – there are hundreds of guides on this process out there.

Unfortunately, even after this it didn’t boot. I had no idea what was wrong. Then, after removing most of my hair I realised that because the partition information had changed, the boot.ini file would need to be updated. Being a Mac user I sort of expect this kind of stuff to “just work”, but if the boot.ini file doesn’t have a correct partition specified, it will just give up, and peace out, not bothering to display an error message of any kind.

Restart, and bingo. Server back online. Now for that second partition. Frustrated at Active@, I installed EASEUS Partition Recovery and decided to give it a shot. Literally SIX seconds later, I had the second drive recovered, mounted and back up and running.

Seriously, WTF. EASEUS Partition Recovery is black magic and totally free and awesome. I cannot recommend it highly enough. If you accidentally “quick format” a drive, EASEUS Partition Recovery is the tool you’re after. There’s even a guide on their site of how to add it as plugin to BartPE.

So at the end of the day I spent $114USD and learnt a valuable lesson – EASEUS is free and the best partition recovery software out there.
