Work in progress

This guide is written for Ubuntu 10.04.

For neo4j-embedded:

sudo apt-get install nginx git-core python-virtualenv postfix openjdk-6-jre-headless postgresql build-dep

For neo4j-rest-client:

sudo apt-get install apache2 libapache2-mod-wsgi git-core python-virtualenv postfix openjdk-6-jre-headless postgresql python-psycopg2 libpq-dev python-dev

For both neo4j versions:
Make a virtual python environment.

cd /opt/python_environments/
sudo virtualenv --no-site-packages norduni

Install needed python modules.

sudo su
source python_environments/norduni/bin/activate
pip install django ipaddr argparse pexpect markdown psycopg2 lucene-querybuilder gunicorn

Add the following python modules if you are running the Neo4j stand alone server:

pip install httplib2

Get the NORDUni files:
For neo4j-embedded:

cd /var/opt/
git clone git://git.nordu.net/norduni.git

For neo4j-rest-client:

cd /var/opt/
git clone git://git.nordu.net/norduni.git
git checkout operation

For both neo4j versions:
Get the NERDS files:

mkdir /opt/norduni/tools/
cd /opt/norduni/tools/
git clone https://github.com/fredrikt/nerds.git

Symlink admin media and the virtual python environment to niweb.

cd /var/opt/norduni/scr/niweb/
ln -s /var/opt/python_environments/norduni/ env
cd static
ln -s ../env/lib/python2.6/site-packages/django/contrib/admin/media/ admin

Set password for database user and create a new database

sudo -u postgres psql postgres
\password postgres
Write password
Write password again
Ctrl+D
sudo -u postgres createdb norduni

Change the django settings.

# Django settings for niweb project
cd /opt/norduni/scr/niweb/
cp generic_settings.py settings.py
vi settings.py

Change at least the following settings.

NIWEB_ROOT = '/opt/norduni/src/niweb/'
# Database settings
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'norduni',
        'USER': 'postgres',
        'PASSWORD': 'secret',
        'HOST': 'localhost'
    }
}
# Neo4j settings
NEO4J_RESOURCE_URI = '/opt/norduni/dependencies/neo4jdb/'

Create a file name niweb in /etc/apache2/conf.d/.

WSGIPythonPath "/var/opt/norduni/scr:/var/opt/norduni/scr/niweb"
WSGIPythonHome "/opt/python_environments/norduni"
WSGIDaemonProcess processes=1 threads=25 # For neo4j-embedded
WSGIApplicationGroup %{GLOBAL}           # For neo4j-embedded
WSGIRestrictStdin Off
WSGIRestrictStdout Off
WSGIScriptAlias / /var/opt/norduni/niweb.wsgi

Add niweb path to niweb.wsgi

sys.path.append('/opt/norduni/src/niweb')

Install nginx for serving static files.
Configure Apache to listen to localhost only and set up proxy through nginx.

Set up a GIT repository for the JSON files produced by the NERDS producers and make a clone in /var/opt/. We have a GIT repository called nistore
and we have made a clone found at /var/opt/nistore/.

Produce JSON files with the producers you want.

Consume the recently produces JSON files with the NORDUni consume scripts.

Install Neo4j graph database

Neo4j 1.5 embedded with Python bindings (recommended)

Install JPype and Neo4j-embedded.

apt-get install python-jpype
pip install neo4j-embedded

Set JAVA_HOME for JPype to work correctly.

export JAVA_HOME=/usr/lib/jvm/java-6-openjdk/jre

Neo4j 1.3 REST stand alone server

Download neo4j-1.3 from http://neo4j.org.
Extract the file to, for example, /var/opt/norduni/dependencies/.

cd /var/opt/norduni/dependencies/
tar xfz neo4j-1.3.tar.gz

Copy the startup script from /var/opt/norduni/scr/scripts/neo4j/ to /etc/init.d/ and then make neo4j start on boot.

update-rc.d /et/init.d/neo4j defaults

You need to shut down port 7474 from anything except localhost.

iptables -A INPUT -p tcp --dport 7474 -s localhost -j ACCEPT
iptables -A INPUT -p tcp --dport 7474 -j DROP

Save the rules and add the following line to your interface configuration so you will restore the rules on a reboot.

bash -c "iptables-save > /etc/iptables.rules"

vi /etc/network/interfaces

iface eth0 inet static
    pre-up iptables-restore < /etc/iptables.rules

Old Apache stuff

Configure the web server to play nice with neo4j-embedded. Install apache2-mpm-prefork libapache2-mod-wsgi.
/etc/apache2.conf

<IfModule mpm_prefork_module>
    StartServers          1
    ServerLimit           1
    MinSpareServers       5
    MaxSpareServers      10
    MaxClients            1
    MaxRequestsPerChild   0
</IfModule>

Add the following lines to /etc/apache2/sites-available/default-ssl

        <LocationMatch "Shibboleth.sso">
           SetHandler None
        </LocationMatch>

        <Location "/accounts/login-federated/">
