These notes are based on a setup used by the "SOftware observatory" workshop, Constant Michael Murtaugh (discussion) 30 janvier 2018 à 10:48 (CET)
Sommaire
Initial image + setup
Downloaded from https://www.raspberrypi.org/downloads/raspbian/
Based on the "lite" image (zip or torrent). As of 20 Jan 2018, this is Raspian "Stretch" lite.
The **lite** image has no desktop / windows session.
Based on 2017-04-10-raspian-jessie-lite.zip
unzip -p 2017-04-10-raspbian-jessie-lite.zip | pv | sudo dd of=/dev/sdc bs=4M
You could use Etcher.io as well
SSH is no longer on by default! So need to connect with a screen first time and turn this on.
sudo raspi-config
Enable ssh under connectivity.
You can also enabled SSH by default after creating the boot SD Card, you just need to create a empty file named SSH and save it the root of your SD Card.
Bring the rest of the software up to date.
sudo apt-get update sudo apt-get upgrade
How to find the IP address of the pi
Simplest way is to connect on a wired network (plug the pi and your laptop into a router with ethernet cables), then type:
ping raspberrypi.local
And you should be able to see the IP address.
Then you can conenct with ssh with:
ssh pi@raspberrypi.local
or with the IP address in place of "raspberrypi.local" if you are on the wifi.
with the default password "raspberry"
Make it easier to login, with an ssh key
Starting from your laptop (open a new Terminal session if you are connected to the pi):
ssh-keygen
Choose the defaults. This generates an "ssh key" pair.
Use the ssh-copy-id utility to send it to the pi.
ssh-copy-id pi@raspberrypi.local
Setup apache to serve the root with custom header + readme's
sudo apt-get install apache2 cd /etc/apache2/sites-available sudo nano 000-default.conf
ServerAdmin webmaster@localhost
# DocumentRoot /var/www/html
DocumentRoot /home/pi
<Directory /home/pi>
Options Indexes FollowSymLinks
AllowOverride none
Require all granted
</Directory>
HeaderName /include/HEADER.shtml
ReadmeName README.html
NB: Sets the HeaderName and ReadmeName directives (part of mod_autoindex).
sudo service apache2 reload
droptoupload.cgi
sudo a2enmod cgi sudo service apache2 restart
Placed 'droptoupload.cgi' in /usr/lib/cgi-bin and tried running it with:
./droptoupload.cgi
Like this is just outputs an HTML form. Looking at http://etherbox.local/cgi-bin/droptoupload.cgi should also display an upload form.
The HEADER.shtml includes a link to this cgi.
sudo chmod +x droptoupload.cgi
HEADER.shtml
Sample Header that adds javascript to:
- Move the README.html to the TOP of the page
- Includes the "droptoupload.cgi" https://gitlab.constantvzw.org/aa/etherbox/raw/master/usr/lib/cgi-bin/droptoupload.cgi
<script src="/cgi-bin/droptoupload.cgi"></script>

}
});
</script>
Better permissions with facl
sudo addgroup pi www-data sudo setfacl -Rm g:www-data:rwX /home/pi sudo setfacl -d -Rm g:www-data:rwX /home/pi
Unfortunately, I had problems then with permissions on the .ssh folder (preventing keys to be used). To remove the fact on just this folder:
sudo chmod g-w /home/pi
Install etherpad
And the version of "nodejs" is now 0.10.29~dfsg-2. So let's try it with etherpad...
sudo apt-get install npm git sudo ln -s /usr/bin/nodejs /usr/bin/node cd /opt sudo git clone https://github.com/ether/etherpad-lite.git sudo mv etherpad-lite etherpad # TODO: don't create home folder! ... find option sudo adduser --system --home=/opt/etherpad --group etherpad sudo chown -R etherpad:etherpad etherpad
Les fichiers se trouvent dans opt/etherpad/var sous forme d'un seul fichier "dirtyDB" - > You should use a dedicated database such as "mysql", if you are planning on using etherpad-in a production environment.
sudo apt-get install mysql-server
Create your setting file.
sudo cp settings.json.template settings.json
then, desactivate the dirty.db file and configure the mysql database
sudo nano settings.json
Find and change this part :
//The Type of the database. You can choose between dirty, postgres, sqlite and mysql
//You shouldn't use "dirty" for for anything else than testing or development
/* "dbType" : "dirty",
//the database specific settings
"dbSettings" : {
"filename" : "var/dirty.db"
},
*/
//An Example of MySQL Configuration
"dbType" : "mysql",
"dbSettings" : {
"user" : "etherpaduser",
"host" : "localhost",
"password": "etherpadpass",
"database": "store",
"charset" : "utf8mb4"
},
Set up Mysql
First thing to do is to install MySQL :
sudo apt-get install mysql-server
Then create the database, for this we need to login with the Root user (super-user) :
sudo su
Run mysql :
mysql
Then create the database and the user 'etherpaduser' with the password 'etherpadpass' :
create database etherpad; grant all on etherpad.* to 'etherpaduser'@'localhost' identified by 'etherpadpass';
Just to test if it works :
mysql -u etherpaduser -p etherpad
Run etherpad for the first time as the etherpad user...
cd /opt/etherpad sudo --user etherpad bin/run.sh
Following the first recipe on this page about deploying etherpad as a systemd service
sudo nano /etc/systemd/system/etherpad.service
[Unit] Description=Etherpad-lite, the collaborative editor. After=syslog.target network.target [Service] Type=simple User=etherpad Group=etherpad WorkingDirectory=/opt/etherpad ExecStart=/usr/bin/nodejs /opt/etherpad/node_modules/ep_etherpad-lite/node/server.js Restart=always [Install] WantedBy=multi-user.target
After this,
sudo service etherpad start
Seems to work! Apparently it's the same as:
systemctl start etherpad-lite
And to start on boot:
systemctl enable etherpad-lite
etherdump
System wide installation of etherdump
Install deps:
sudo apt install python-pip python-dev sudo pip install python-dateutil jinja2 html5lib
Install from repo:
git clone http://murtaugh@gitlab.constantvzw.org/aa/etherdump.git cd etherdump sudo python setup.py install
Setup the folder
cd /home/pi mkdir etherdump cd etherdump etherdump init
Type in:
http://etherbox.local:9001/
And paste the API key. (Look at: http://etherbox.local/opt/etherpad/APIKEY.txt)
styles.css + versions.js
scp styles.css versions.js pi@etherbox.local:etherdump/lib
The URLs of these files are options to the etherdump pull command and should match.
etherdump.sh + cron
Make the script that runs automatically.
nano etherdump.sh
#!/bin/bash # PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games cd /home/pi/etherdump etherdump pull --all --pub /home/pi/etherdump --css lib/styles.css --script lib/versions.js etherdump index *.meta.json > index.html
And set it to run every 5 minutes
crontab -e
PATH=/home/pi/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin # m h dom mon dow command */5 * * * * /home/pi/etherdump.sh > /home/pi/cron.log.txt 2>&1
The PATH is important. It can also be in the etherdump.sh but basically should match what you see when you "echo $PATH" (for the script to run in the same way as for the pi user).
Other software
sudo apt-get install emacs-nox screen pdftk pandoc texlive-latex-recommended texlive-fonts-recommended sudo pip install csvkit
To install
- screen
- pandoc + latex
- pdftk
- csvkit
What about
- texlive-xetex texlive-luatex pandoc-citeproc etoolbox
The current version of pandoc in this raspbian is 1.12.4.2~dfsg-1+b3 We will use latex for PDF generation (via pandoc)
(which is way better than 1.9 of the previous raspian, and even beats the instructions for compiling 1.11.1)
MORE
sudo apt-get install pandoc texlive-latex-recommended texlive-fonts-recommended
Was able to:
pandoc --from markdown hello.markdown -o hello.pdf
Access point
Taken from this "ultimate" guide
apt-get install dnsmasq wireless-tools hostapd # the next wasn't necessary for jessie, but for completeness.. RPI3 broadcom chip apt-get install firmware-brcm80211 rmmod brcmfmac modprobe brcmfmac
Give fixed IP to wlan0 interface, edit /etc/network/interfaces switch off the built in stuff and add (section 2):
auto eth0 allow-hotplug eth0 iface etho inet dhcp ################################# # 1. ORIGINAL settings... use wpa_supplicant for client mode #allow-hotplug wlan0 #iface wlan0 inet manual # wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf # ################################# # 2. Fixed IP address (for hotspot / hostapd) auto wlan0 iface wlan0 inet static address 10.9.8.7 netmask 255.255.255.0 #################################
Replace /etc/dnsmasq.conf with:
interface=wlan0 dhcp-range=10.9.8.10,50.9.8.254,12h address=/#/10.9.8.7 no-resolv
Edit /etc/hostapd/hostapd.conf file (adjust depending on driver/hardware)
interface=wlan0 driver=nl80211 ssid=WiFeels hw_mode=g channel=6
Edit /etc/default/hostapd and add
DAEMON_CONF="/etc/hostapd/hostapd.conf"
Make hostapd start at boot
update-rc.d hostapd defaults
Reboot.
Makeserver + etherpad (experimental!)
Ingredients
- Etherdump's pad.html with <rel> links including LIVE EDIT URLs
- THIS should replace/complement makeserver's EDIT button
Key question: Makeserver as a separate view ?! (probably)
TRY as 2 separate things ... basically AS IS...
Install:
cd /home/pi/software git clone http://murtaugh@gitlab.constantvzw.org/aa/makeserver.git cd makeserver git submodule init git submodule update sudo pip install twisted jinja2
BUGFIX with twisted / SSL issues:
sudo pip install twisted[tls]
DIDN"T FIX sudo pip install twisted==16.0.0
Seems to work!
TODO
- Why are the links hardcoded long form in etherdump index (fails then via makeserver based in home)?
Extra
Changed dnsmasq.conf
interface=wlan0 dhcp-range=10.9.10.50,10.9.10.254,12h #address=/#/10.9.10.7 # no-resolv
AND added to /etc/hosts
10.9.10.7 etherbox.local
and this seems to then work over the direct hotspot connection.
