Contents
Purpose
Boot into Chrome Kiosk mode and display a web page for digital signage.
Setup
Packages
A fresh install of CentOS 7 minimal. Please note the following
- x11 server did not install with the group install of Xfce, so it was installed separately.
- [1]Keyboard and mouse did not work out the box, and I had to install the evdev drivers.
Base Packages
yum -y update yum -y install epel-release yum makecache yum -y install chromium wget zstd
XFCE
yum -y group install Xfce yum -y install xorg-x11-drv-evdev nxorg-x11-server-Xorg
OpenBox
yum install -y openbox xorg-x11-drv-libinput xorg-x11-server-utils
Unclutter
- Install unclutter[3][4], this is useful for getting rid of the mouse pointer when not in use.
- NOTE: I ran into issues downloading from archlinux, quick and dirty google search had me run across a git repo.[5]
Repo method
This has not been fully tested and may contain bad code.
yum install -y git libev-devel libX11-devel libXt-devel libXi-devel asciidoc yum groupinstall "Development Tools" git clone https://github.com/Airblader/unclutter-xfixes && cd unclutter-xfixes mkdir /usr/share/licenses/unclutter/ make make install
Arch method
wget -O unclutter.tar.zst --content-disposition --max-redirect=5 https://www.archlinux.org/packages/community/x86_64/unclutter/download/ zstd -d unclutter.tar.zst -o unclutter.tar tar -xf unclutter.tar mv usr/bin/unclutter /usr/bin/unclutter rm -rf usr
TTY1 Autologin
Now create the auto-login process.
useradd publicuser rm /etc/systemd/system/getty.target.wants/getty@tty1.service cp /lib/systemd/system/getty@.service /etc/systemd/system/getty@tty1.service sed -i -e "s/\/sbin\/agetty/\0 --autologin publicuser/" /etc/systemd/system/getty@tty1.service ln -s /etc/systemd/system/getty@tty1.service /etc/systemd/system/getty.target.wants/getty@tty1.service cat << EOF >>/home/publicuser/.bash_profile if [[ -z \$DISPLAY ]] && [[ \$(tty) = /dev/tty1 ]]; then # Check if we have a display and we're on TTY1 startx else echo "Please contact the help desk and provide the following" echo "IP : " echo "Hostname : $hostname" fi EOF cat << EOF>>/home/publicuser/.xinitrc exec startxfce4 EOF reboot
After the reboot, you should see the desktop start up. If it does not troubleshoot.
Configure Chromium
Auto-start
cat << EOF>>/etc/xdg/autostart/kiosk.desktop [Desktop Entry] Encoding=UTF-8 Name=Kiosk GenericName=program Comment=LobbyKiosk Exec=chromium-browser --noerrdialogs --kiosk http://siteurl.tld Icon=/usr/share/pixmaps/program.jpg Terminal=false Type=Application Categories= OnlyShowIn=XFCE; EOF
Homepage
- WIP : Does not work as-is.
- For now you run this after chromium creates it's directories.
sed -i s'|start.fedoraproject.org|yoursite.tld|g' /home/publicuser/.config/chromium/Default/Preferences
Configure Power Settings and Disable Mouse Pointer
We want to prevent the system from going to sleep, blanking the screen, loading the screen saver[8], or showing the pointer on the screen.
One issue I am having is understanding the best method for exporting the display. I am too used to working in bash and not with a gui. The following export does not work, but the display settings appear to still work.
Initially the xset commands were getting ignored by xfce power management. In order to get around this I had to use xfconf-query[9] to make things stick
- Create the script
cat << EOF>>/home/publicuser/power.sh #!/bin/sh sleep 10 export DISPLAY=$(who | grep -E "publicuser pts\/[0-9]" | grep -Eo "\(:[0-9][.]?[0-9]?\)" | sed 's/(//; s/)//') xfconf-query -c xfce4-power-manager -p /xfce4-power-manager/dpms-enabled -s false /usr/bin/unclutter -grab EOF chmod +x /home/publicuser/power.sh sed -i 's/<\/property>/\ \ <property\ name=\"blank-on-ac\"\ type=\"int\"\ value=\"0\"\/>\n&/g' /home/publicuser/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-power-manager.xml
- Create the auto-launch of the script.
cat << EOF>>/etc/xdg/autostart/power.desktop [Desktop Entry] Encoding=UTF-8 Name=powersettings GenericName=program3 Comment=DisablePower Exec=/home/publicuser/power.sh Icon=/usr/share/pixmaps/program.jpg Terminal=false Type=Application Categories= OnlyShowIn=XFCE; EOF
Setup WordPess
But first I download and extract the files needed over ssh.
wget https://wordpress.org/latest.zip
unzip latest.zip
mv wordpress /var/www/html/
find /var/www/html/wordpress/ -type d -exec chmod 755 {} \;
find /var/www/html/wordpress/ -type f -exec chmod 644 {} \;
mkdir /var/www/html/wordpress/logs
chown -R apache:apache /var/www/html/wordpress
- Setup a vhost to load the site.
cat << EOF >>/etc/httpd/conf.d/vhost.conf <VirtualHost *:80> ServerName localhost DocumentRoot "/var/www/html/wordpress" </VirtualHost> EOF
- Up until now I have been setting this up remotely, however I will now need to start using the ol' keyboard and mouse so I can configure using localhost. Follow the standard wordpress setup[10].
