Documentation

Prerequisites

Before the configuration, ensure that the required dependencies have been installed in the system environment. For details about how to install the dependencies, see this section.

This section applies to users who use the Atlas 200 AI accelerator module (RC) and Atlas 500 Pro AI edge server (model 3000). Users who use the Atlas 500 AI edge station (model 3000) can skip this section.

  • Before installing the dependencies, check whether they have been installed based on the Description column in Table 1. If the dependencies have been installed, do not install them again. If not, install them based on the Installation Command or Procedure column.
  • Ensure that you can run the su command to switch to another user to run commands.

    The modification method is as follows:

    Find the /etc/pam.d/su file and add auth sufficient pam_rootok.so to the auth module.

  • Linx 6.0.90, Linx 6.0.100, and UOS 20 do not have default online addresses for installation sources. Therefore, you are advised to add installation sources before installing dependencies.
  • For Ubuntu, Linx 6.0.90, Linx 6.0.100, and UOS 20, if an error is reported when you install the dependencies, run the apt update command to update the dependency packages before installing the dependencies.
  • This document also describes how to install dependencies offline on CentOS 7.6. (Other systems do not support the offline dependency installation. You need to install dependencies online.) For details, see Installing Dependencies Offline on CentOS.
  • Check and clear the firewall restriction rules for ports 4999 and 8886.

Network Bandwidth Requirements

To ensure the normal running of the AtlasEdge and avoid frame freezing or slow upload and download, the network bandwidth must meet the following requirements:

  • The bandwidth between the edge device where the AtlasEdge is located and the web client must be equal to or greater than 20 Mbit/s.
  • The bandwidth between the edge device where the AtlasEdge is located and FusionDirector must be equal to or greater than 50 Mbit/s.
  • Other network requirements: latency < 30 ms, packet loss rate < 3%

  • For details about how to install the dependency in CentOS 7.6, see Installing Dependencies Offline on CentOS.
NOTE:
  • For CentOS, if the following message is displayed by running the docker ps command after Docker has been installed, run the systemctl restart docker command to restart the Docker service.
    Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
  • For security purposes, after Docker is successfully installed, you can perform security hardening based on service requirements. For details about the hardening items, see Other Products.
  • GO has discarded the Common Name certificate verification. If you want to use the Docker constructed using GO 1.15 to 1.17 and the certificate verification function, perform the following operations:
    1. Configure Environment=GODEBUG=x509ignoreCN=0 in the [Service] field in the Docker service configuration file docker.service.
    2. Run the systemctl daemon-reload and systemctl restart docker.service commands for the configuration to take effect.
