Purpose
Powers that be wanted a TV mounted in a lobby, with content playing on it for visitors to ignore. At first I was told to install a flash drive and play images with the flush mount TV. Instead I thought it would be a good idea to have a NUC installed behind the TV running a web browser in full screen mode, displaying a WordPress site that my boss could manage (He really likes wordpress).
Hardware
Intel BOXNUC6CAYH
-2GB DDR3 RAM (I had laying around, should be enough to display a single web page and run the background tasks)
-Intel(R) Celeron(R) CPU J3455 @ 1.50GHz (Came with the NUC. Just enough to display a web page and run WordPress)
-KingDian S100 16GB SSD (This was dirt cheap, and will probably die with the lack of RAM installed.)
This is connected to the wifi since there is no ethernet installed behind the TV. But since the site is on the unit I can live with broken connections. A simple script later on should take care of this.
Setup
Packages
A fresh install of CentOS 7, and the usual basics. Please note the following
- x11 server did not install with the group install of Xfce, so it was installed seperately.
- [1]Keyboard and mouse did not work out the box, and I had to install the evdev drivers. Granted no one should be using a keyboard and mouse with this system, but I will be running VNC as an extra method for managing the system (Windows weenies will be asking fewer questions this way.)
yum -y update yum -y install epel-release yum makecache yum -y install htop nano xorg-x11-server-Xorg smartmontools chromium xorg-x11-drv-evdev yum -y group install Xfce
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>>/hom/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
