Description of how to install the software needed for Lobber.

  4. Database server

Common

All hosts are running Ubuntu (10.04) with the following extra packages and customizations.

apt-get install git-core git-doc ssl-cert git-core python-virtualenv
apt-get install postfix
# local only configuration!

Web application and tracker server

Install the following packages:

apt-get install apache2 libapache2-mod-wsgi libapache2-mod-shib2 libpq-dev python-dev python-twisted
pip install orbited

Orbited can not be installed in the lobber python environment because it requires python-twisted.

pip install orbited

You might need these:

python-egenix-mxdatetime python-egenix-mxtools python-pycurl python-openssl 

Set up a virtual python environment (virtualenv) and activate it.

virtualenv --no-site-packages /path/to/lobber_env
source /path/to/lobber_env/bin/activate

Install the needed python applications. (Yes, orbited again...needed as import in django)

pip install django django-tagging django-form-utils stomp.py psycopg2 orbited

You might need these:

pip install uuid django-evolution django-extensions werkzeug

Get Lobber from git.nordu.net and check out the latest stable version.

git clone git@git.nordu.net:lobber.git
cd lobber
git checkout bud-light

Create the a log, torrent and a dropbox directory in the lobber root directory. Make the writable by the Apache user.

cd /path/to/lobber/
mkdir logs
mkdir torrents
mkdir dropbox

Symlink the environment directory and Django admin media directory in to the src directory.

cd /path/to/lobber/src
ln -s /path/to/lobber_env env
ln -s env/lib/python2.6/site-packages/django/contrib/admin/media admin-media

Edit paths and other options in settings.py.

settings.py
BASE_DIR = '/path/to/lobber'

APP_ADDR = 'host_ip or FQDN'
TRACKER_ADDR = 'host_ip or FQDN'

ADMINS = (
    ('Your name', 'your@email.net'),

DATABASE_ENGINE = 'postgresql_psycopg2'
DATABASE_NAME = 'lobber'
DATABASE_USER = 'lobber'
DATABASE_PASSWORD = 'secret_password'
DATABASE_HOST = 'database host'
DATABASE_PORT = 'database port'

DROPBOX_DIR = '/path/to/lobber/dropbox'

# Make this unique, and don't share it with anybody.
SECRET_KEY = 'secret'

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',      # For the Permission model.
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.admin',
    'tagging',
    'lobber.extensions',
    'lobber.userprofile',
    'lobber.share',
    'lobber.links',
    'lobber.tracker',
    'lobber.auth'
)

If you are using Django 1.3 (standard from pip) then you need to change your database settings to:

settings.py
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'lobber'
        'USER': 'lobber'
        'HOST': 'database_server'
        'PORT': 'database_port'
    }
}

Synchronize the database.

./dev-django-admin.sh syncdb

Setup Orbited by creating /etc/orbited.cfg:

orbited.cfg
[listen]
http://:9001
stomp://:61613

[access]
* -> localhost:61613

[static]

[global]
session.ping_interval = 300
user=www-data

[logging]
debug=STDERR,debug.log
info=STDERR,info.log
access=STDERR,info.log
warn=STDERR,error.log
error=STDERR,error.log

#Don't enable debug by default
enabled.default=info,access,warn,error

and make sure that orbited is started like this automatically at boot:

echo "orbited -c /etc/orbited.cfg" >> /etc/rc.local

Then start orbited:

orbited -c /etc/orbited.cfg &

Activate some Apache modules:

a2enmod shib2
a2enmod headers
a2enmod rewrite
a2enmod proxy
a2enmod proxy_http

Restart Apache

/etc/init.d/apache2 restart

Edit lobber/src/lobber.wsgi:

lobber.wsgi
sys.path.append('/path/to/lobber/src')

Create /etc/apache2/conf.d/lobber:

lobber
WSGIPythonPath "/path/to/lobber:/path/to/lobber/src"
WSGIPythonHome "/path/to/lobber/src/env"
WSGIRestrictStdout Off
WSGIScriptAlias / /path/to/lobber/src/lobber.wsgi

Edit /etc/apache2/sites-available/default-ssl:

default
Alias /admin-media /path/to/lobber/admin-media
Alias /site-media /path/to/lobber/site-media

Missing documentation

Documentation on how to set up Apache to handle https is missing.

Perhaps useful links for Apache SSL configuration: http://www.tc.umn.edu/~brams006/selfsign.html http://www.tc.umn.edu/~brams006/selfsign_ubuntu.html

Usual problems:

  • /path/to/lobber/logs/web.log is not writable by www-data (apache user).
  • /path/to/lobber/torrents/ is not writable by www-data (apache user).
  • /path/to/lobber/dropbox/ is not writable by www-data (apache user).
  • /path/to/lobber/db/ (if you are using sqlite) is not writable by www-data (apache user).

Missing documentation

Documentation on how to set up federated login using mod_shib2 should be added or linked to.

Set up cron jobs for expiring old torrents, keys and peers.

# m h dom mon dow command
*/5 * * * * cd /path/to/lobber/src/ && ./dev-django-admin.sh expire_peers 5
0 0 * * * cd /path/to/lobber/src/ && ./dev-django-admin.sh expire_torrents
5 0 * * * cd /path/to/lobber/src/ && ./dev-django-admin.sh expire_keys

To be able to accept file uploads in the Lobber web application you need to install a Lobber storage node on the web application and tracker server.

Storage node

See Running a storage node

Note that the web application and tracker server needs a storage node nowadays – that's how we do file upload.

Database server

apt-get install postgresql-client-8.4

Look at the official Django database documentation.

Setting up your own sandbox

  1. apt-get install python-virtualenv
  2. virtualenv /mina/envs/lobber
  3. . /mina/envs/lobber/bin/activate
  4. pip install django django-extensions django-tagging orbited uuid django-evolution stomp.py werkzeug psycopg2
  5. git clone git@git.nordu.net:lobber.git (alt. git pull)
  6. cd lobber
  7. git checkout <branch>
  8. mkdir db
  9. mkdir logs
  10. cd src
  11. ./dev-django-admin.sh syncdb
  12. ln -s /mina/envs/lobber env
  13. ln -s env/lib/python2.6/site-packages/django/contrib/admin/media admin-media
  14. Edit paths in settings.py
  15. ./dev-django-admin.sh runserver_plus
