Install SENSR on Red Hat

Overview

SENSR is compatible with Red Hat 8 to ensure better maintainability in particular at critical facilities. This section describes how to deploy SENSR in such an environment.

Prerequisites

1. Replace podman by docker

    sudo yum install -y yum-utils
    sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
    #This will install docker engine & remove any conflicting packages like podman & libraries
    sudo yum install -y docker-ce docker-ce-cli containerd  docker-buildx-plugin docker-compose-plugin --allowerasing
    sudo systemctl enable docker
    sudo systemctl restart docker

2. Add ACL rules for docker and kubernetes

    sudo firewall-cmd --permanent --add-port=6443/tcp
    sudo firewall-cmd --permanent --zone=trusted --add-source=10.42.0.0/16 
    sudo firewall-cmd --permanent --zone=trusted --add-source=10.43.0.0/16
    sudo firewall-cmd --reload  

3. Install Nvidia-driver-535

• Ensure the system is up to date by running sudo yum update -y
• Install development tools and kernel headers

    sudo yum groupinstall "Development Tools" -y
    sudo yum install kernel-devel kernel-headers -y

• Go to NVIDIA Driver Download page and download the driver version 535 for Linux.
• Prepare for the installation: Switch to a text-based login and stop the GUI to prevent conflicts during the driver installation

    sudo systemctl set-default multi-user.target
    sudo systemctl isolate multi-user.target

• Blacklist Nouveau driver: This will prevent it from loading to run the NVIDIA driver

sudo bash -c 'echo "blacklist nouveau" > /etc/modprobe.d/blacklist-nouveau.conf'
sudo bash -c 'echo "options nouveau modeset=0" >> /etc/modprobe.d/blacklist-nouveau.conf'

• Regenerate the initial RAM filesystem to enact the changes: sudo dracut --force
• Reboot: sudo reboot
• Install the NVIDIA driver (follow the on-screen instructions to complete the installation):

cd /path/to/downloaded/driver
chmod +x NVIDIA-Linux-x86_64-535.XX.run
sudo ./NVIDIA-Linux-x86_64-535.XX.run

• Switch back to GUI

sudo systemctl set-default graphical.target
sudo systemctl isolate graphical.target

• Reboot: sudo reboot
• Verify the installation by running nvidia-smi

Install SR-Launcher

1. Get the rpm package from your local FAE or request it through suppor@seoulrobotics.org
2. Install the package: sudo yum install ./sr-launcher-cli_<ver_number>_amd64.rpm
3. Follow the instructions available in the manual to deploy SENSR.
