The packages

According to this, there are some convenient packages of Nuxeo DM and Nuxeo DAM for Ubuntu. For my local drinking buddies, I'll just expand a bit on what's written there.

(If you prefer to build your Nuxeo DAM from scratch from the development branch, I explain how to do that here.)

Installing Sun's Java

I'll stick with discussing just the Nuxeo DAM package; I'm assuming everything works similarly for DM.

Those packages have Sun's Java as a strict dependency, so you'll need to add Sun's repository (unless it's already in your /etc/apt/sources.list file, of course):

sudo apt-add-repository "deb http://archive.canonical.com/ lucid partner"

at which point, you would:

$ sudo apt-get update
$ sudo apt-get install sun-java6-jdk

Installing the Nuxeo package(s)

First, add the Nuxeo repository and update the Apt cache:

$ sudo apt-add-repository "deb http://apt.nuxeo.org/ lucid-snapshots/"
$ sudo apt-get update

at which point you should be able to install the package of your choice:

$ sudo apt-get install nuxeo-dam-jboss

Do you really need Sun's Java?

Technically, you need it for the installation, but there's no obvious reason that you need to actually be running it. On my system, I'm still using the OpenJDK implementation, as you can see:

$ java -version
java version "1.6.0_18"
OpenJDK Runtime Environment (IcedTea6 1.8) (6b18-1.8-0ubuntu1)
OpenJDK 64-Bit Server VM (build 14.0-b16, mixed mode)
$

and until such time as OpenJDK is clearly incompatible with any software package, I'll keep using it.

Starting Nuxeo DAM

Simple:

$ sudo service nuxeo-dam start

give it a bit of time, then browser over to http://localhost:8080/nuxeo. Seems to work fine.

Some possible improvements

For one thing, the /etc/init.d/nuxeo-dam management script could stand to be fleshed out more -- it supports only the "start", "stop" and "restart" directives, but not "status," which would be nice. But that's just nitpicking.

A larger issue is whether or not OpenJDK 6 is really compatible with Nuxeo. If it is, then the Nuxeo packages should drop their explicit dependency on Sun's Java, and add the more generic dependency of just java6-sdk, a dependency that can be satisfied by either of those two Java implementations.

UPDATE, Jun 29: Making the NUXEO management script more verbose with a "status" directive

Personally, I really like my service management scripts to have a "status" directive, so I've attached an enhanced /etc/init.d/nuxeo-dam file to this article which adds that. It's not rocket surgery, I just find it handy. Now you can do:

$ sudo service nuxeo-dam status
Nuxeo DAM is running (pid 16158).
$ sudo service nuxeo-dam stop
 * Stopping Nuxeo DAM
..........Nuxeo stopped.
$ sudo service nuxeo-dam status
Nuxeo DAM is not running.
$

It's not deep programming, it just amuses me.

In fact, to be pedantic, all init scripts should follow the LSB guidelines described here.

UPDATE: Nuxeo DM and Nuxeo DAM can't be installed at the same time

After running Nuxeo DAM just fine for the last little while, I tried installing the Ubuntu Nuxeo DM package as well. That didn't go well as it appears that both packages dearly want to set the symlink /usr/bin/nuxeoctl to point to their respective control script under /opt. Unsurprisingly, that doesn't work very well.
