    • Hey Charles, the grayed-out button implies that you have missed out in configuring one or settings from step 3 right through step 11. Ensure all the options are configured. For security policy, you can leave the default settings as they are and proceed with the installation.

  1. You should include CIS recommended steps, like creating separate mount points for /home, /tmp, etc. It is much easier to do at set up then having to change after the server is created.

  4. How can I tell if Centos 8 will run on a given server?

    I want to buy a refurb but I am unsure if I will be able to run Centos 8?

    Reply
    • Hey Tim, CentOS 8 will run quite well on a system with 2GB RAM, 2 GHz or higher processor and 20 GB hard disk space. Does your refurb meet the requirements?
