    It was a helpful article sir. In Step 17 “Installing Webmin”, after I install it, I am asked to login http://myipaddress:10000.
    When I do that, I get “The owner “abc” has configured their website improperly…..”

    For VirtualBox installation, you might need to copy the repository file http://download.virtualbox.org/virtualbox/rpm/el/virtualbox.repo to /etc/yum.repos.d/. Otherwise, you could get a “No package VirtualBox-X.X available.” error.

  3. thanks million for your good post,
    i find 2 small mistakes in spelling of commands that maybe because of them some users face problem in copy and paste the commands from the post.
    1. “permanent” spell in below section is not correct:
    Add service tomcat and default port (8080) through firewall and reload settings.
    # firewall-cmd —zone=public —add-port=8080/tcp —permannet

    2.reload in below command has just one dash(-):
    To add a service say http, temporarily and reload firewalld.
    # firewall-cmd –reload

    I’m not sure who wrote this but it seems clear that he/she never attempted to follow her own instructions.
    The first step in setting up the network is to invoke

    yum install net-tools

    yum install requires a functioning network with accessible repositories if using the minimal CD.

    These instructions simply won’t ever work with a minimal installation CD.

  5. Dumb says:

    Cannot connect to X server — not entirely sure what this means.

    For people unfamiliar with CLI text editors (vi, vim, nano), etc.
    You can configure static IP and hostname in a GUI environment, just type:

    # nmtui

    Once there, you can edit what you need.

    If ‘nmtui’ command not found, install it:

    yum install NetworkManager-tui

    Done!
    My 2 cents…

    Thank You for collecting all that useful and not so useful in one article. :)
    Hmm, interesting, how many copypasters have used your sample passwords unchanged? :)
    Typos:
    # nmap 127.0.01
    # visudo
