Chapter 17. Installing on IBM System z Systems • 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 17.1, “Installation Program Widgets as seen in Boot Loader Configuration”, the cursor is positioned on the OK button. Figure 17.2, “Installation Program Widgets as seen in Disk Druid”, shows the cursor on the Edit button. 2.1. 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). 3. Running the Installation Program After following the steps outlined in Chapter 16, Steps to Get You Started for booting an LPAR or VM system, ssh to the configured Linux install system on the IBM System z. Although the text mode installation program is run by default for most installations, you can optionally run the graphical installation program available for both VM and LPAR installations via the NFS installation method. 180
Interface Note If you have a slow network connection or prefer a text-based installation, do not set the DISPLAY= variable in the parm file. The text-based installation is similar to the graphical installation; however, the graphical installation offers more package selection details and other options not available in text-based installs. It is strongly recommended to use the graphical installation whenever possible. To run the graphical installation, use a workstation that has an X Window System server or VNC client installed. Use an SSH client that allows X11 forwarding or a Telnet client. SSH is strongly recommended for its security features as well as its ability to forward X and VNC sessions. Enable X11 forwarding in your SSH client prior to connecting to the Linux image (the Linux guest running on z/VM). 3.1. Installation using X11 Forwarding For example, to connect to the Linux image and display the graphical installation program using OpenSSH with X11 forwarding on a Linux workstation, type the following at the workstation shell prompt: ssh -X linuxvm.example.com The -X option enables X11 forwarding. The graphical installation program cannot be started if your DNS or hostnames are not set correctly, or the Linux image is not allowed to open applications on your display. You can prevent this by setting a correct DISPLAY= variable. Add the parameter DISPLAY=workstationname:0.0 in the parameter file, replacing workstationname with the hostname of the client workstation connecting to the Linux Image. Allow the Linux image to connect to the workstation using the command xhost +linuxvm on the local workstation. If the graphical installation via NFS does not automatically begin for you, verify the DISPLAY= variable settings in the parm file. If performing a VM installation, rerun the installation to load the new parm file on the reader. Additionally, make sure when performing an X11 forwarded display that the X server is started on the workstation machine. Finally, make sure either the NFS, FTP or HTTP protocols are selected, as all 3 methods support graphical installations. 3.2. Installation using VNC If you are using VNC, a message on the workstation SSH terminal prompts you to start the VNC client viewer and details the VNC display specifications. Enter the specifications from the SSH terminal into the VNC client viewer and connect to the Linux image to begin the installation. Once you have logged into the Linux image the loader will start the installation program. 181
