Gentoo Installation instructions

Gentoo Installation instructions
Part 1: Emerge packages

You need the following packages from the portage tree:

Package	Version	unstable?
dev-python/lxml	2.2.8
dev-python/pyyaml	3.09
dev-python/sphinx	1.0.5
dev-python/nose	0.11.4
sci-libs/scipy	0.7.2-r1
dev-python/numpy	1.4.1
dev-python/django	1.2.3
dev-python/python-gflags	1.4	~x86
dev-python/paramiko	1.7.6
dev-python/fabric	0.9.3	~x86
sci-libs/gdal	1.6.3-r1
dev-python/matplotlib	1.0.0
dev-python/guppy	0.1.9	~x86
dev-java/ant	1.7.1
virtual/jdk	1.6.0

Before emerging, set the ~x86 keyword for the unstable packages in the /etc/portage/package.keywords file to let emerge know you want the newest, unstable version:

echo dev-python/python-gflags ~x86 >> /etc/portage/package.keywords
echo dev-python/paramiko ~x86 >> /etc/portage/package.keywords
echo dev-python/guppy ~x86 >> /etc/portage/package.keywords

You can emerge all these packages at once with the following command (as root):

emerge -va dev-python/lxml dev-python/pyyaml dev-python/sphinx dev-python/nose \
 sci-libs/scipy dev-python/numpy dev-python/django dev-python/python-gflags \
 dev-python/paramiko  dev-python/fabric sci-libs/gdal dev-python/matplotlib \
 dev-python/guppy dev-java/ant virtual/jdk

Part 2: Manually install additional packages

Some of the packages required to run OpenQuake are not (yet) available in the portage tree, or are outdated. Therefore, some manual installations are necessary.

Python packages:

Package	Version	URL
jpype	0.5.4	http://jpype.sourceforge.net/
geohash	0.7.1	https://code.google.com/p/python-geohash/
shapely	1.2.08	http://pypi.python.org/pypi/Shapely
Celery	2.2.2	http://pypi.python.org/pypi/celery#downloads

Make sure you get the right version of geohash, there are two (the other is called “Geohash” with capital G. )
Each of these needs to be unpacked and then built and installed with:

cd <<package-version>>
python setup.py build    # as user
python setup.py install  # as root

Servers

REDIS:
Use the stable version from (2.0.4) from http://redis.io/download
None of the versions available in portage work with OpenQuake (1.2.5, 2.2.0_rc4).
You don’t need to install it, just unpack it and start it right there where you unpacked it. It works fine with the default settings.

cd redis-<<version>>
redis-server            # as root

RABBITMQ:

Download the generic unix version 2.3.1-1 from http://www.rabbitmq.com/server.html
This newest version is not yet available in portage.
Unpack and start it with:

cd rabbitmq-<<version>>
sbin/rabbitmq-server       # as root

Then follow the instructions on the http://openquake.org/documentation/installation/ page to create the celery users etc. using sbin/rabbitmqctl

Further assistance you can get help through our mailing list or on irc.freenode.net (freenode network) at #openquake.
