LINUX Prerequisites - AMS Advanced Application Developer's Guide

LINUX Prerequisites

Observe the requirements listed in Migrating Workloads: Prerequisites for Linux and Windows and ensure the following before submitting a WIGS RFC:

  • The latest enhanced networking drivers are installed; see Enhanced Networking on Linux.

  • Third-party software components that will conflict with AMS components have been removed:

    • Anti-virus Clients

    • Backup Clients

    • Virtualization software (such as VM Tools or Hyper-V Integration services)

    • Access Management Software (Such as SSSD, Centrify, or PBIS)

  • Ensure SSH is properly configured - This temporarily enables private key authentication for SSH. AMS uses this with our configuration management tool. Use these commands:

    sudo grep -q "^PubkeyAuthentication" /etc/ssh/sshd_config && sudo sed "s/^PubkeyAuthentication=.*/PubkeyAuthentication yes/" -i /etc/ssh/sshd_config || sudo sed "$ a\PubkeyAuthentication yes" -i /etc/ssh/sshd_config
    sudo grep -q "^AuthorizedKeysFile" /etc/ssh/sshd_config && sudo sed "s/^AuthorizedKeysFile=.*/AuthorizedKeysFile %h\/.ssh\/authorized_keys/" -i /etc/ssh/sshd_config || sudo sed "$ a\AuthorizedKeysFile %h/.ssh/authorized_keys" -i /etc/ssh/sshd_config

  • Ensure Yum is properly configured - RedHat requires licensing to use their Yum Repositories. The instance needs to be licensed via a Satellite Server or RedHat Cloud Server. Use one of these links if licensing is needed:

  • If you use Red Hat Satellite, WIGS requires the addition of Red Hat Software Collections (RHSCL). The WIGS system uses RHSCL to add a Python3.6 interpreter alongside whatever is configured on the system. To support this solution, the following repositories must be available:

    • rhel-server-rhscl

    • rhel-server-releases-optional
