RIP

Description

Rip is a dedicated playout system wich launch a video using a PIR sensor on a Raspberry Pi 400.

It's based on the great work of Alex Lubbock with vidlooper.

A really light apache webapp provide the ability to change the movie and the splashscreen. So the wifi interface of the raspberry pi 400 is turned into an access point.

setup

1. setup hostname and basic raspbian setup

By default raspberry OS (aka raspbian) boot in graphical mode in it's full version.

I think that the lite version does not.

pi@RIP2:~ $ sudo raspi-config

In raspi-config change default password for security.

1 System Options > S3 Password

Then change hostname to the one you want.

1 System Options > S4 Hostname

Change default Boot to autologin console

1 System Options > S5 Autologin

Now for the display properties, if you have some issues with a black border and the picture in center of it, go to.

2 Display Options >> D2 Underscan >> Yes

Set the GPU memory amount to be enough for display HD video or more if you need. Be careful with this parameter because it's a fine tuned setting and may result in some performance issues.

4 Performance Options >> P2 Memory >> something like 512 Mo or 256 Mo will do.

You can hang around to see other parameters but for now we're done with those basics setup.

2. update / upgrade raspbian

Raspbian has release a new version so --allow-releaseinfo-change option is important and need to be done 2 times.

pi@RIP2:~ $ sudo apt-get update --allow-releaseinfo-change
pi@RIP2:~ $ sudo apt-get update --allow-releaseinfo-change
pi@RIP2:~ $ sudo apt-get upgrade
pi@RIP2:~ $ sudo apt-get dist-upgrade

3. Installing software

pi@RIP2:~ $ sudo apt-get install hostapd dnsmasq apache2 vsftpd php omxplayer fbi
pi@RIP2:~ $ sudo pip3 install vidlooper

4. Configure Wifi AP, dnsmasq and IP settings

Many thanks to t2age link on his github repo for the Wifi AP part.

Stop all services that we have just install.

pi@RIP2:~ $ sudo service dnsmasq stop
pi@RIP2:~ $ sudo service vsftpd stop
pi@RIP2:~ $ sudo service apache2 stop
pi@RIP2:~ $ sudo service hostapd stop

Save a copy of dhcpcd.conf and edit dhcpcd.conf

pi@RIP2:~ $ sudo mv /etc/dhcpcd.conf /etc/dhcpcd.conf.orig
pi@RIP2:~ $ sudo nano /etc/dhcpcd.conf

add these lines :

interface wlan0  
static ip_address=192.168.50.1/24  
nohook wpa_supplicant  

and uncomment eth0 profile to enable dhcp fallback to a static IP

# define static profile
profile static_eth0
static ip_address=192.168.10.23/24
static routers=192.168.10.254
static domain_name_servers=8.8.8.8 8.8.4.4

# fallback to static profile on eth0
interface eth0
fallback static_eth0

You can just send a copy of the dhcpcd.conf in this folder with scp.

So close your remote session

pi@RIP2:~ $ exit

and then in the host command prompt do.

pi@RIP2:~ $ scp ./dhcpcd.conf pi@YOUR-PI-IP-ADDRESS:dhcpcd.conf
pi@YOUR-PI-IP-ADDRESS's password:

Replace YOUR-PI-IP-ADDRESS by the raspberry pi ip address. You will be ask to type your ssh password.

Then log back your pi with ssh and put the file in the right place.

pi@RIP2:~ $ sudo mv dhcpcd.conf /etc/dhcpcd.conf

Do the same for hostapd.conf and dnsmask.conf. of course replace YOUR-PI-IP-ADDRESS by your pi ip address. In host :

pi@RIP2:~ $ scp ./hostapd.conf pi@YOUR-PI-IP-ADDRESS:hostapd.conf
pi@YOUR-PI-IP-ADDRESS's password:
pi@RIP2:~ $ scp ./dnsmask.conf pi@YOUR-PI-IP-ADDRESS:dnsmask.conf
pi@YOUR-PI-IP-ADDRESS's password:

And back in the pi.

pi@RIP2:~ $ sudo mv hostapd.conf /etc/hostapd/hostapd.conf
pi@RIP2:~ $ sudo mv dnsmask.conf /etc/dnsmask.conf

Obviously, you have to change some configuration in /etc/hostapd/hostapd.conf to suite your needs. In fact adjust as minimal requirements the SSID and the PASSWORD on these lines.

ssid=AP-SSID
wpa_passphrase=AP-WIFI-PASSWORD

And we are not done yet with hostapd. you have to setup the default config file that hostapd will use. To do that, edit /etc/default/hostapd

pi@RIP2:~ $ sudo nano /etc/default/hostapd

And uncomment the line DAEMON_OPTS and put the path of the conf file we have copy. Ctrl-X to exit nano then yes to save changes again.

DAEMON_CONF="/etc/hostapd/hostapd.conf"

Unmask (unlock) hostapd service

sudo systemctl unmask hostapd.service  
sudo systemctl enable hostapd.service  

now we are ready to reboot and see if the access point is working properly.

pi@RIP2:~ $ sudo reboot

5. Configure vsftpd, apache2 and php :

From host copy vsftpd.conf

pi@RIP2:~ $ scp ./vsftpd.conf pi@YOUR-PI-IP-ADDRESS:vsftpd.conf
pi@YOUR-PI-IP-ADDRESS's password:

pi@RIP2:~ $ cd
pi@RIP2:~ $ sudo mv vsftpd.conf /etc/vsftpd.conf
pi@RIP2:~ $ mkdir VidLooper
pi@RIP2:~ $ sudo chgrp -R www-data VidLooper
pi@RIP2:~ $ sudo chmod -G www-data ftp
pi@RIP2:~ $ sudo chmod -R g+rwx ./VidLooper
pi@RIP2:~ $ git clone https://github.com/a2msystemes/RIP
pi@RIP2:~ $ cd RIP
pi@RIP2:~ $ cp -R site/ ../VidLooper
pi@RIP2:~ $ sudo cp /etc/apache2/sites-available/000-default.conf /etc/apache2/site
s-available/001-RIP-webApp.conf
pi@RIP2:~ $ sudo a2dissite 000-default.conf
Site 000-default disabled.
To activate the new configuration, you need to run:
  systemctl reload apache2
pi@RIP2:~ $ sudo systemctl reload apache2.service
pi@RIP2:~ $ cd RIP
pi@RIP2:~ $ sudo cp ./001-RIP-webApp.conf /etc/apache2/sites-available/
pi@RIP2:~ $ sudo a2ensite 001-RIP-webApp.conf
pi@RIP2:~ $ sudo apachectl configtest
pi@RIP2:~ $ sudo systemctl reload apache2.service
pi@RIP2:~ $ sudo cp ./php.ini /etc/php/[php-version]/apache2/php.ini
pi@RIP2:~ $ sudo cp ./010_rip-reboot /etc/sudoers.d/010_rip-rebootc
pi@RIP2:~ $ sudo reboot
