# Setting up a Raspberry Pi Piku Server from Scratch
|
|
|
|
## DISCLAIMER!
|
|
|
|
### These instructions are correct as of April 1st 2016
|
|
|
|
Start by flashing a SD card with [the latest Raspbian Jessie Lite image](https://www.raspberrypi.org/downloads/raspbian/).
|
|
|
|
# Do this in your Raspberry Pi as 'pi' user
|
|
|
|
Boot it, launch *raspi-config* to perform (at least) the following configuration:
|
|
|
|
```bash
|
|
# as 'pi' user
|
|
sudo raspi-config
|
|
```
|
|
|
|
* 1) expand filesystem
|
|
* 2) change default user password
|
|
* 3) set up memory split as you wish (for a headless server, 16MB for GPU)
|
|
|
|
Optionally:
|
|
|
|
* 4) set up over-clocking.
|
|
|
|
# Secure your install
|
|
|
|
Delete the existing SSH keys and recreate them (why? [read this](https://www.raspberrypi.org/forums/viewtopic.php?t=126892)).
|
|
|
|
```bash
|
|
# 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:
|
|
|
|
```bash
|
|
# as 'pi' user
|
|
sudo apt update
|
|
sudo apt upgrade
|
|
```
|
|
|
|
# Install required packages
|
|
|
|
As of April 2016, the shipping versions with Raspbian are recent enough to run `piku`:
|
|
|
|
```bash
|
|
# 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
|
|
```
|
|
|
|
# Meanwhile, go get the goodies while Raspberry Pi is rebooting
|
|
|
|
(We assume you know about ssh keys and have one "at hand", you'll need to copy it)
|
|
|
|
Clone the [piku repo](https://github.com/rcarmo/piku) somewhere and copy files to your Raspberry Pi
|
|
|
|
```bash
|
|
# 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
|
|
```
|
|
|
|
# Back to the Pi
|
|
|
|
Prepare uWSGI (part one):
|
|
```bash
|
|
# 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:
|
|
|
|
```bash
|
|
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
|
|
|
|
```bash
|
|
# 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):
|
|
|
|
```bash
|
|
# as 'pi' user
|
|
sudo systemctl start uwsgi-piku
|
|
sudo systemctl status uwsgi-piku.service
|
|
```
|
|
|
|
|
|
# If you're still here, odds are your Pi is ready for work
|
|
|
|
Go back to your machine and try these commands:
|
|
|
|
```bash
|
|
# as yourself in your desktop/laptop computer
|
|
ssh piku@your_machine
|
|
|
|
Usage: piku.py [OPTIONS] COMMAND [ARGS]...
