Deploy Deploy
======== ======
This tutorial describes the installation of a production environment. To
have a fully working environment, you have to set up the other components
as well. The full procedure is included in the :doc:`Puppet recipes
<puppet>` available for CIRCLE Cloud.
This component should normally deployed to a single head node.
This is the web-based entry point to the end users, and also the manager of
the compute and storage nodes.
Preparation
-----------
To get the project running, launch a new Ubuntu 14.04 machine, and
log in to it over SSH.
.. warning::
If the first character of the hostname should not be a digit, because
RabbitMQ won't work with it.
The machine should have an :abbr:`fqdn (fully qualified domain name)`,
which shoud be correctly printed by :kbd:`hostname -f`. You can achieve
this with an IP address (e.g. 127.0.1.1) in :file:`/etc/hosts` having the
short hostname as first, and the fqdn as second alias).
Setting up required software
----------------------------
Update the package lists, and install the required system software::
sudo apt-get update
sudo apt-get install --yes virtualenvwrapper postgresql git \
python-pip rabbitmq-server libpq-dev python-dev ntp memcached \
libmemcached-dev gettext wget pwgen nginx
Set up *PostgreSQL* to listen on localhost and restart it::
sudo sed -i /etc/postgresql/9.1/main/postgresql.conf -e '/#listen_addresses/ s/^#//'
sudo /etc/init.d/postgresql restart
Also, create a new database and user::
pwgen 12 >pgpw
sudo -u postgres createuser -S -D -R circle
sudo -u postgres psql <<<"ALTER USER circle WITH PASSWORD '$(cat pgpw)';"
sudo -u postgres createdb circle -O circle
Configure RabbitMQ: remove the guest user, add virtual host and user with
proper permissions::
pwgen 12 >rmqpw
sudo rabbitmqctl delete_user guest
sudo rabbitmqctl add_vhost circle
sudo rabbitmqctl add_user cloud $(cat rmqpw)
sudo rabbitmqctl set_permissions -p circle cloud '.*' '.*' '.*'
Set up nginx to serve the CIRCLE portal. ::
sudo tee /etc/nginx/conf.d/default.conf <<END
ignore_invalid_headers on;
server {
listen 443 ssl default;
ssl on;
ssl_certificate /etc/ssl/certs/ssl-cert-snakeoil.pem;
ssl_certificate_key /etc/ssl/private/ssl-cert-snakeoil.key;
location /static {
alias ${PWD}/circle/static_collected; # your Django project's static files
}
location / {
uwsgi_pass unix:///tmp/uwsgi.sock;
include /etc/nginx/uwsgi_params; # or the uwsgi_params you installed manually
}
location /vnc/ {
proxy_pass http://localhost:9999;
proxy_set_header X-Real-IP \$remote_addr;
proxy_set_header Host \$host;
proxy_set_header X-Forwarded-For \$proxy_add_x_forwarded_for;
# WebSocket support (nginx 1.4)
proxy_http_version 1.1;
proxy_set_header Upgrade \$http_upgrade;
proxy_set_header Connection "upgrade";
}
}
server {
listen 80 default;
rewrite ^ https://\$host/; # permanent;
}
END
sudo /etc/init.d/nginx restart
.. warning::
For a production deployment, you should use certificates issued by a
recognized certificate authority. Until you get it, you can use a
self-signed one automatically generated by the package.
Setting up Circle itself
------------------------
Clone the git repository::
git clone https://git.ik.bme.hu/circle/cloud.git circle
Set up *virtualenvwrapper* and the *virtual Python environment* for the
project::
source /etc/bash_completion.d/virtualenvwrapper
mkvirtualenv circle
Set up default Circle configuration and activate the virtual environment::
cat >>/home/cloud/.virtualenvs/circle/bin/postactivate <<END
export DJANGO_SETTINGS_MODULE=circle.settings.production
export DJANGO_DB_HOST=localhost
export DJANGO_DB_PASSWORD=$(cat pgpw)
export DJANGO_FIREWALL_SETTINGS='{"dns_ip": "152.66.243.60", "dns_hostname":
"localhost", "dns_ttl": "300", "reload_sleep": "10",
"rdns_ip": "152.66.243.60", "default_vlangroup": "publikus"}'
export AMQP_URI='amqp://cloud:$(cat rmqpw)@localhost:5672/circle'
export CACHE_URI='pylibmc://127.0.0.1:11211/'
END
workon circle
cd ~/circle
You should change DJANGO_FIREWALL_SETTINGS to your needs.
Install the required Python libraries to the virtual environment::
pip install -r requirements.txt
Sync the database and create a superuser::
circle/manage.py syncdb --all --noinput
circle/manage.py migrate --fake
circle/manage.py createsuperuser
Copy the init files to Upstart's config directory and start the manager and
the portal application server::
sudo cp miscellaneous/mancelery.conf /etc/init/
sudo start mancelery
sudo cp miscellaneous/portal-uwsgi.conf /etc/init/
sudo start portal-uwsgi
This is where you describe how the project is deployed in production.
