Start by flashing a SD card with the latest Raspbian Jessie Lite image.
Boot it, launch raspi-config to perform (at least) the following configuration:
# as 'pi' user
sudo raspi-config
-
- expand filesystem
-
- change default user password
-
- set up memory split as you wish (for a headless server, 16MB for GPU)
Optionally:
-
- set up over-clocking.
Delete the existing SSH keys and recreate them (why? read this).
# as 'pi' user
sudo rm -v /etc/ssh/ssh_host_*
sudo dpkg-reconfigure openssh-server
sudo reboot
This will recreate the server keys. Next, update your system:
# as 'pi' user
sudo apt update
sudo apt upgrade
As of April 2016, the shipping versions with Raspbian are recent enough to run piku
:
# as 'pi' user
sudo apt install -y python-virtualenv python-pip git uwsgi uwsgi-plugin-python incron nginx
sudo pip install -U click
sudo reboot
(We assume you know about ssh keys and have one "at hand", you'll need to copy it)
Clone the piku repo somewhere and copy files to your Raspberry Pi
# as yourself in your desktop/laptop computer
scp piku.py uwsgi-piku.service nginx.default.dist incron.dist pi@your_machine:/tmp
scp your_public_ssh_key.pub pi@your_machine:/tmp
Prepare uWSGI (part one):
# as 'pi' user
sudo ln -s `which uwsgi` /usr/local/bin/uwsgi-piku
sudo systemctl disable uwsgi
sudo cp /tmp/uwsgi-piku.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable uwsgi-piku
Prepare nginx:
sudo apt-get install nginx incron
# Set up nginx to pick up our config files
sudo cp /tmp/nginx.default.dist /etc/nginx/sites-available/default
# Set up incron to reload nginx upon config changes
sudo cp /tmp/incron.dist /etc/incron.d/piku
sudo systemctl restart incron
sudo systemctl restart nginx
Create 'piku' user and set it up
# as 'pi' user
sudo adduser --disabled-password --gecos 'PaaS access' --ingroup www-data piku
sudo su - piku
# this is now done as 'piku' user
mkdir ~/.ssh
chmod 700 ~/.ssh
cp /tmp/piku.py ~/piku.py
python piku.py setup
python piku.py setup:ssh /tmp/id_rsa.pub
# return to 'pi' user
exit
Prepare uWSGI (part two):
# as 'pi' user
sudo systemctl start uwsgi-piku
sudo systemctl status uwsgi-piku.service
Go back to your machine and try these commands:
# as yourself in your desktop/laptop computer
ssh piku@your_machine
