8 Ubuntu 12.04.3 (64) - Django 1.3.x
9 ==================================
11 This guide assumes that installation is carried out in /srv/flowspy directory. If other directory is to be used, please change the corresponding configuration files. It is also assumed that the root user will perform every action.
13 Required system packages
14 ------------------------
16 Update and install the required packages::
20 apt-get install mysql-server apache2 memcached libapache2-mod-proxy-html gunicorn beanstalkd python-django python-django-extensions python-django-south python-django-tinymce tinymce python-mysqldb python-yaml python-memcache python-django-registration python-ipaddr python-lxml mysql-client git python-django-celery python-paramiko python-gevent vim
23 Set username and password for mysql if used
26 If you wish to deploy an outgoing mail server, now it is time to do it. Otherwise you could set FoD to send out mails via a third party account
30 If you are using mysql, you should create a database::
32 mysql -u root -p -e 'create database fod'
35 Required application packages
36 -----------------------------
37 Get the required packages and install them
39 - ncclient: NETCONF python client::
42 git clone https://github.com/leopoul/ncclient.git
44 python setup.py install
46 - nxpy: Python Objects from/to XML proxy::
49 git clone https://code.grnet.gr/git/nxpy
51 python setup.py install
53 - flowspy: core application. Installation is done at /srv/flowspy::
56 git clone https://code.grnet.gr/git/flowspy
59 Application configuration
60 =========================
62 Copy settings.py.dist to settings.py::
64 cp settings.py.dist settings.py
66 Edit settings.py file and set the following according to your configuration::
68 ADMINS: set your admin name and email (assuming that your server can send notifications)
69 DATABASES (to point to your local database). You could use views instead of tables for models: peer, peercontacts, peernetworks. For this to work we suggest MySQL with MyISAM db engine
70 SECRET_KEY : Make this unique, and don't share it with anybody
71 STATIC_URL (static media directory) . If you have followed the above this should be: /srv/flowspy/static
72 TEMPLATE_DIRS : If you have followed the above this should be: /srv/flowspy/templates
73 CACHE_BACKEND: If you have followed the above this should be: memcached://127.0.0.1:11211/?timeout=3600
74 Alternatively you could go for redis with the corresponding Django client lib.
75 NETCONF_DEVICE (tested with Juniper EX4200 but any BGP enabled Juniper should work). This is the flowspec capable device
76 NETCONF_USER (enable ssh and netconf on device)
78 If beanstalk is selected the following should be left intact.
79 BROKER_HOST (beanstalk host)
80 BROKER_PORT (beanstalk port)
83 If beanstalk is selected the following should be left intact.
84 BROKER_URL (beanstalk url)
85 SHIB_AUTH_ENTITLEMENT (if you go for Shibboleth authentication)
86 NOTIFY_ADMIN_MAILS (bcc mail addresses)
87 PROTECTED_SUBNETS (subnets for which source or destination address will prevent rule creation and notify the NOTIFY_ADMIN_MAILS)
88 The whois client is meant to be used in case you have inserted peers with their ASes in the peers table and wish to get network info for each one in an automated manner.
91 If you wish to deploy FoD with Shibboleth change the following attributes according to your setup:
92 SHIB_AUTH_ENTITLEMENT = 'urn:mace'
93 SHIB_ADMIN_DOMAIN = 'example.com'
94 SHIB_LOGOUT_URL = 'https://example.com/Shibboleth.sso/Logout'
95 SHIB_USERNAME = ['HTTP_EPPN']
96 SHIB_MAIL = ['mail', 'HTTP_MAIL', 'HTTP_SHIB_INETORGPERSON_MAIL']
97 SHIB_FIRSTNAME = ['HTTP_SHIB_INETORGPERSON_GIVENNAME']
98 SHIB_LASTNAME = ['HTTP_SHIB_PERSON_SURNAME']
99 SHIB_ENTITLEMENT = ['HTTP_SHIB_EP_ENTITLEMENT']
101 If you have not installed an outgoing mail server you can always use your own account (either corporate or gmail, hotmail ,etc) by adding the following lines in settings.py::
103 EMAIL_USE_TLS = True #(or False)
104 EMAIL_HOST = 'smtp.example.com'
105 EMAIL_HOST_USER = 'username'
106 EMAIL_HOST_PASSWORD = 'yourpassword'
107 EMAIL_PORT = 587 #(outgoing)
111 Soon we will release a version with django-registration as a means to add users and Shibboleth as an alternative
113 Let's move on with some copies and dir creations::
115 cp urls.py.dist urls.py
117 chown -R root:www-data log/
122 Apache operates as a gunicorn Proxy with WSGI and Shibboleth modules enabled.
123 Depending on the setup the apache configuration may vary::
130 If shibboleth is to be used::
132 apt-get install libapache2-mod-shib2
135 Now it is time to configure beanstalk, gunicorn, celery and apache.
140 Enable beanstalk by editting /etc/default/beanstalkd::
142 vim /etc/default/beanstalkd
144 Uncomment the line **START=yes** to enable beanstalk
148 service beanstalkd start
153 create and edit /etc/gunicorn.d/fod::
155 vim /etc/gunicorn.d/fod
157 FoD is served via gunicorn and is then proxied by Apache. If the above directory conventions have been followed so far, then your configuration should be::
161 'working_dir': '/srv/flowspy',
163 '--bind=127.0.0.1:8081',
166 '--worker-class=egg:gunicorn#gevent',
175 Celery is used over beanstalkd to apply firewall rules in a serial manner so that locks are avoided on the flowspec capable device. In our setup celery runs via django. That is why the python-django-celery package was installed.
177 Create the celeryd daemon at /etc/init.d/celeryd::
179 # ============================================
180 # celeryd - Starts the Celery worker daemon.
181 # ============================================
183 # :Usage: /etc/init.d/celeryd {start|stop|force-reload|restart|try-restart|status}
184 # :Configuration file: /etc/default/celeryd

210 test -f "$CELERY_DEFAULTS" && . "$CELERY_DEFAULTS"
211 if [ -f "/etc/default/celeryd" ]; then

231 if [ ! -d "$CELERYD_LOG_DIR" ]; then
232 mkdir -p $CELERYD_LOG_DIR
234 if [ ! -d "$CELERYD_PID_DIR" ]; then
235 mkdir -p $CELERYD_PID_DIR
238 # Extra start-stop-daemon options, like user/group.
239 if [ -n "$CELERYD_USER" ]; then

248 if [ -n "$CELERYD_CHDIR" ]; then
249 DAEMON_OPTS="$DAEMON_OPTS --workdir=\"$CELERYD_CHDIR\""
254 if [ ! -c /dev/null ]; then
255 echo "/dev/null is not a character device!"
261 export PATH="${PATH:+$PATH:}/usr/sbin:/sbin"
265 $CELERYD_MULTI stop $CELERYD_NODES --pidfile="$CELERYD_PID_FILE"

306 $CELERYCTL status $CELERYCTL_OPTS
320 echo "Usage: /etc/init.d/celeryd {start|stop|restart|try-restart|kill}"
327 and make it executable::
329 chmod +x /etc/init.d/celeryd
331 celeryd requires a /etc/default/celeryd file to be in place.
332 Thus we are going to create this file (/etc/default/celeryd)::
334 vim /etc/default/celeryd
336 Again if the directory conventions have been followed the file should be::
338 # Name of nodes to start, here we have a single node
340 # or we could have three nodes:
341 #CELERYD_NODES="w1 w2 w3"
343 # Where to chdir at start.
344 CELERYD_CHDIR="/srv/flowspy/"
345 # How to call "manage.py celeryd_multi"
346 CELERYD_MULTI="$CELERYD_CHDIR/manage.py celeryd_multi"
348 # How to call "manage.py celeryctl"
349 CELERYCTL="$CELERYD_CHDIR/manage.py celeryctl"
351 # Extra arguments to celeryd
352 #CELERYD_OPTS="--time-limit=300 --concurrency=8"
354 # Name of the celery config module.
355 CELERY_CONFIG_MODULE="celeryconfig"
357 # %n will be replaced with the nodename.
358 CELERYD_LOG_FILE="$CELERYD_CHDIR/celery_var/log/celery/%n.log"
359 CELERYD_PID_FILE="$CELERYD_CHDIR/celery_var/run/celery/%n.pid"
361 # Workers should run as an unprivileged user.
365 # Name of the projects settings module.
366 export DJANGO_SETTINGS_MODULE="settings"
370 Apache proxies gunicorn. Things are more flexible here as you may follow your own configuration and conventions. Create and edit /etc/apache2/sites-available/fod. You should set <server_name> and <admin_mail> along with your certificates. If under testing environment, you can use the provided snakeoil certs. If you do not intent to use Shibboleth delete or comment the corresponding configuration parts inside **Shibboleth configuration** ::
372 vim /etc/apache2/sites-available/fod
374 Again if the directory conventions have been followed the file should be::

498 You are not far away from deploying FoD. When asked for a super user, create one::
501 python manage.py syncdb
502 python manage.py migrate
504 Restart, gunicorn and apache::
506 service gunicorn restart && service apache2 restart
510 Log in to the admin interface via https://<your ip>/fod/admin. Go to Peer ranges and add a new range (part of/or a complete subnet), eg. 83.212.0.0/19
511 Go to Peers and add a new peer, eg. id: 1, name: Test, AS: 16503, tag: TEST and move the network you have crteated from Avalable to Chosen. From the admin front, go to User, and edit your user. From the bottom of the page, select the TEST peer and save.
512 Last but not least, modify as required the existing (example.com) Site instance. You are done. As you are logged-n via the admin, there is no need for Shibboleth. Go to https://<your ip>/fod/ and create a new rule. Your rule should be applied on the flowspec capable device after aprox. 10 seconds.
516 Via the admin interface you can modify flatpages to suit your needs
520 Inside the static folder you will find two empty png files: fod_logo.xcf (Gimp file) and shib_login.dist.png. Edit those two with your favourite image processing software and save them as fod_logo.png (under static/img/) and shib_login.png (under static/). Image sizes are optimized to operate without any other code changes. In case you want to incorporate images of different sizes you have to fine tune css and/or html as well.
524 Under the templates folder (templates), you can alter the footer.html file to include your own footer messages, badges, etc.
528 Under the templates folder (templates), you can alter the welcome page - welcome.html with your own images, carousel, videos, etc.
