NOTE: CentOS Enterprise Linux 5 is built from the Red Hat Enterprise Linux source code. Other than logo and name changes CentOS Enterprise Linux 5 is compatible with the equivalent Red Hat version. This document applies equally to both Red Hat and CentOS Enterprise Linux 5.

12.5. The Text Mode Installation Program User Interface

The Red Hat Enterprise Linux text mode installation program uses a screen-based interface that includes most of the on-screen widgets commonly found on graphical user interfaces. Figure 12.2, “Installation Program Widgets as seen in Boot Loader Configuration”, and Figure 12.3, “Installation Program Widgets as seen in Disk Druid”, illustrate the screens that appear during the installation process.

Note

While text mode installations are not explicitly documented, those using the text mode installation program can easily follow the GUI installation instructions. One thing to note is that manipulation of LVM (Logical Volume Management) disk volumes is only possible in graphical mode. In text mode it is only possible to view and accept the default LVM setup.

Here is a list of the most important widgets shown in Figure 12.2, “Installation Program Widgets as seen in Boot Loader Configuration” and Figure 12.3, “Installation Program Widgets as seen in Disk Druid”:

  • Window — Windows (usually referred to as dialogs in this manual) appear on your screen throughout the installation process. At times, one window may overlay another; in these cases, you can only interact with the window on top. When you are finished in that window, it disappears, allowing you to continue working in the window underneath.

  • Checkbox — Checkboxes allow you to select or deselect a feature. The box displays either an asterisk (selected) or a space (unselected). When the cursor is within a checkbox, press Space to select or deselect a feature.

  • Text Input — Text input lines are regions where you can enter information required by the installation program. When the cursor rests on a text input line, you may enter and/or edit information on that line.

  • Text Widget — Text widgets are regions of the screen for the display of text. At times, text widgets may also contain other widgets, such as checkboxes. If a text widget contains more information than can be displayed in the space reserved for it, a scroll bar appears; if you position the cursor within the text widget, you can then use the Up and Down arrow keys to scroll through all the information available. Your current position is shown on the scroll bar by a # character, which moves up and down the scroll bar as you scroll.

  • Scroll Bar — Scroll bars appear on the side or bottom of a window to control which part of a list or document is currently in the window's frame. The scroll bar makes it easy to move to any part of a file.

  • Button Widget — Button widgets are the primary method of interacting with the installation program. You progress through the windows of the installation program by navigating these buttons, using the Tab and Enter keys. Buttons can be selected when they are highlighted.

  • Cursor — Although not a widget, the cursor is used to select (and interact with) a particular widget. As the cursor is moved from widget to widget, it may cause the widget to change color, or the cursor itself may only appear positioned in or next to the widget. In Figure 12.2, “Installation Program Widgets as seen in Boot Loader Configuration”, the cursor is positioned on the OK button. Figure 12.3, “Installation Program Widgets as seen in Disk Druid”, shows the cursor on the Edit button.

12.5.1. Using the Keyboard to Navigate

Navigation through the installation dialogs is performed through a simple set of keystrokes. To move the cursor, use the Left, Right, Up, and Down arrow keys. Use Tab, and Shift-Tab to cycle forward or backward through each widget on the screen. Along the bottom, most screens display a summary of available cursor positioning keys.

To "press" a button, position the cursor over the button (using Tab, for example) and press Space or Enter. To select an item from a list of items, move the cursor to the item you wish to select and press Enter. To select an item with a checkbox, move the cursor to the checkbox and press Space to select an item. To deselect, press Space a second time.

Pressing F12 accepts the current values and proceeds to the next dialog; it is equivalent to pressing the OK button.

Caution

Unless a dialog box is waiting for your input, do not press any keys during the installation process (doing so may result in unpredictable behavior).
