The most recent URD version is 1.0.3.

The easiest way of installing is by using the ubuntu package:

• http://urdland.com/urd_1.0.3-1_all.deb

  Alternatively, you can install from source:

• http://urdland.com/urd-1.0.3.tar.gz

Older versions are still available for nostalgic reasons from the FAQ page.

Installing

(See below for information with regards to updating an existing URD)

From the debian package:

You can use packages to make installation even easier. There are two options,
either you download the .deb package from this website or you use the GetDeb
repository so you can simply use apt-get. GetDeb only works for Ubuntu though!

.deb package:
Download to your debian-based (e.g. Debian or Ubuntu) linux PC.
Doubleclick on the file to install, or alternatively run:

# sudo dpkg -i urd_1.0.3-1_all.deb

GetDeb repository:
See the installation instructions on how to install this repository at www.getdeb.net.
After that, it's just:

(This will install URD in /usr/share/urd, and add an apache alias for /urd to that directory)

From source:

Arie was so nice to make a quick installation manual for Ubuntu 7.10,
which should be similar for newer versions as well. With a bit of tweaking these are the steps:

Installing the web server, database server, and script processor:

# sudo apt-get update
# sudo apt-get upgrade
# sudo apt-get install apache2 php5 mysql-server 
# sudo apt-get install php5-cli php5-mysql php5-xmlrpc php5-curl
# sudo apt-get install yydecode unrar par2 trickle smarty

Restart Apache:

# /etc/init.d/apache2 restart

Download the webcomponents and change permissions:

# sudo cd /var/www/
# wget urdland.com/urd-1.0.3.tar.gz
# sudo tar zxf urd-1.0.3.tar.gz
# mv urd-1.0.3 urd
# sudo chown -R www-data:www-data urd/ 
# sudo chmod -R u+w urd/

Optionally create urd user for dropping privileges to:

# sudo ./install.sh

(This is only needed if you tend to run ./urdd.sh manually and as root)

After the first installation...

there are probably two things you need to change:

Change PHP's max memory usage:

# sudo vi /etc/php5/cli/php.ini
memory_limit = 128M

Uncomment the include path (for Smarty):

# sudo vi /etc/php5/apache2/php.ini
include_path = ".:/usr/share/php" 

 URD configuration and installation:

Now you can start the installation by accessing the URD website address!
(http://[YOUR IP-ADDRESS OR HOSTNAME]/urd/)

Updating

If you are already running URD and wish to update it to the latest version,
this is what you should do:

From the debian package:

Download to your debian-based (e.g. Debian or Ubuntu) linux PC.
Doubleclick on the file to install, or alternatively run:

# sudo dpkg -i urd_1.0.3-1_all.deb

That should be all!

From source:

Download the webcomponents and change permissions:

# sudo cd /var/www/
# wget urdland.com/urd-1.0.3.tar.gz
# sudo tar zxf urd-1.0.3.tar.gz
# sudo cp -rf urd-1.0.3 urd
# sudo chown -R www-data:www-data urd/ 
# sudo chmod -R u+w urd/
# cd install
# sudo ./update.sh

This should upgrade your old database, while keeping the settings etc!
