Red Hat Training

A Red Hat training course is available for Red Hat Enterprise Linux

18.2.4. Installation Phase 3

In installation phase 3 you will use anaconda in graphical, text-based, or cmdline mode:
  • Graphical mode

    This can be used through a VNC client (recommended) or through an X11 server. You can use your mouse and keyboard to navigate through the screens, click buttons, and enter text in fields.

  • Text-based mode

    This interface does not offer all interface elements of the GUI and does not support all settings. Use this for interactive installations if you cannot use a VNC client or X11 server.

  • cmdline mode

    This is intended for automated installations on System z. (Refer to Section 26.6, “Parameters for Kickstart Installations”)

If you have a slow network connection or prefer a text-based installation, do not use X11 forwarding when logging in over the network and do not set the display= variable in the parameter file (refer to Section 26.4, “VNC and X11 Parameters” for details). In Red Hat Enterprise Linux 6.9 the text-based installation has been reduced to minimize user interaction. Features like installation on FCP-attached SCSI devices, changing partition layout, or package selection are only available with the graphical user interface installation. Use the graphical installation whenever possible. (Refer to Chapter 23, Installation Phase 3: Installing Using Anaconda.)
