Updating and Preparing the System

Resonate RFID Reader Management 2.1 Software Installation Guide

The following steps describe how to update and prepare each system. Perform the steps for each system intended for the cluster.

Update the system packages.

For Ubuntu:

sudo apt-get update && sudo apt-get upgrade -y

For Red Hat:

sudo dnf update -y

Set up locales.

The system should use UTF-8 locales to avoid locale-related issues with MicroK8s.

sudo localectl set-locale en_US.UTF-8
export LANG=en_US.UTF-8

Configure huge pages for performance.

Resonate

databases take advantage of huge pages for better performance. Set the number of huge pages to at least 2048.

echo "vm.nr_hugepages = 2048" | sudo tee -a /etc/sysctl.d/20-microk8s-hugepages.conf
sudo sysctl -w vm.nr_hugepages=2048

Check if system restart is needed.

You might need to restart the system if there are kernel updates or other critical updates applied. Check for the presence of the /var/run/reboot-required file.

For Ubuntu:

if [ -f /var/run/reboot-required ]; then
    echo "System restart required"
    sudo reboot
fi

For Red Hat:

needs-restarting -r && echo "System restart required" && sudo reboot
