# Installing Linux

& Logon on VMTOOLS

& Inside VMTOOLS 192 disk make sure that there is a file called PROFILE EXEC.

X PROFILE EXEC D

& If it is empty, use input mode and paste the following content:

/* PROFILE EXEC for Linux virtual servers */
'CP SET RUN ON'
'CP SET PF11 RETRIEVE FORWARD'
'CP SET PF12 RETRIEVE'
'ACC 592 C'
'PIPE CP QUERY' userid() '| var user'
parse value user with id . dsc .
if (dsc = 'DSC') then /* user is disconnected */
'CP IPL 100'
else /* user is interactive -> prompt */
do
say 'Do you want to IPL Linux from minidisk 100? y/n'
parse upper pull answer .
if (answer = 'Y') then 'CP IPL 100'
end

The PROFILE EXEC that you just copied is a REXX EXEC that is analogous to a .bash_profile startup script. If the user ID is logged on in a disconnected mode (usually via XAUTOLOG), Linux will be IPLed from minidisk 100. Otherwise, the user is prompted.

& Logon on LINUX1, answer "no" when asked to IPL 100.

& Run the setup REXX (The name of the file may differ depending on the distruibution, ask your instructor).

LINUX

& The Linux boot output will show up and at the end you may see:

& You should be prompted for Installation Instructions, these steps are covered in class with your instructor.

& After all steps, you should see messages showing the installation system being loaded. For example:

...
Loading Installation System (1/6) (24640 kB) - 3%  4%  5%  6%  7%  8%
...

& A VNC server process will be started. You should see the following messages:

starting VNC server...
A log file will be written to: /var/log/YaST2/vncserver.log ...
***
***
You can connect to <host>, display :1 now with vncviewer
***
Or use a Java capable browser on http://<host>:5801/
***
*** Starting YaST2 ***

& Start a VNC viewer session to the installation process.

& You should see a window entitled Welcome. Select your Language and Keyboard. After reading the License Agreement, click the check-box I Agree to the License Terms, then click Next.

& At the Disk Activation window, click Configure DASD Disks.

& At the DASD Disk Management window:

&& Click Select or Deselect for the two read/write disks (100, 101, 102, 103 and 104).

&& Click Activate on the Perform Action pop-up menu. If the DASDs have not been formatted previously, you will be asked if you want to format them now. Format the DASDs now. This will take a few minutes.

&& If you want to make sure to get the disks in a certain device order, activate them one by one. The first disk will be /dev/dasda, the second disk will be /dev/dasdb, and so on.

&& The DASDs will be activated quickly.

&& Click Next when the formatting is complete.

&& In the Disk Activation window, click Next.

& If you see a pop-up window stating "The partitioning on disk X is not readable by the partitioning tool parted...", click OK

& From this point, the installation process behaves identically to any other architecture.

& In the Installation Mode window, accept the default of New installation and click Next. & In the Clock and Time Zone window, select your time settings and click Next. & In the Installation Settings window, click the tab Expert. & In the Installation Settings window, click Partitioning. & In the Preparing Hard Disk window, accept the default of Customer Partitioning (for experts) and click Next. & In the Expert Partitioner window and the System View column on the left, click a plus sign next to Hard Disks to expand a list of all available disks, check figure 10.3 below.

& Double-click the IBM-DASD that corresponds to the 100 minidisk in the Available Storage section. In this example, it is /dev/dasda (about 1GB) & In the Hard Disk: /dev/dasda section, click the Add button to add a partition. & In the Add Partition window on /dev/dasda, set partition size to Maximum Size (1.10GB) and click Next. & On the next screen, accept the defaults (Format partition, Ext3 file system, Mount partition, and a Mount Point of /), as shown in Figure 10.4. Click Finish.

& Create an empty partition /dev/dasdb, /dev/dasdc, /dev/dasdd in the same fashion as you did to create /dev/dasda but (Select /dev/dasdb => Add => Maximum Size => Do not format/Do not mount partition). Accept the default size of all the space. Check figure 10.5

& For /dev/dasde format the partition as Swap. Check figure 10.6

& Now /dev/dasdb,c,d can be used to create a volume group. Click Volume Management as shown on Figure 10.7.

& Click Add => Volume Group. & At the Add Volume Group window, set the volume group name to optvg. & Click Add after selecting /dev/dasdb1 to the Selected Physical Volumes. Click Finish.

& Click Add => Volume Group again. & At the Add Volume Group window, set the volume group name to system. & Click Add after selecting /dev/dasdc1 to the Selected Physical Volumes. Click Finish.

& Click Add => Volume Group again. & At the Add Volume Group window, set the volume group name to home. & Click Add after selecting /dev/dasdd1 to the Selected Physical Volumes. Click Finish.

& Your Volume Management screen should be like this:

& Back in Expert Partitioner, click the plus sign to the left of Volume Management. You should see the new home, system and optvg volume group. & Click on each and the Volume Group window will be displayed, as shown on Figure 10.9. It shows there are no logical volumes defined. Start with home VG and Click Add.

& Enter home as the name for new logical volume and click Next. & On the Add Logical Volume window, click the Maximum Size radio button (452Mb) Click Next. & Accept ext3 as the File System type and the Mount point of /home. Click Finish. & Now click on optvg mount point and create a opt using the Maximum Size of optvg, File System type ext3 and Mount point of /opt. & For system vg you will create 3 Logical Volumes: && tmp - /tmp - 500MB ext3 && usr - /usr - 2GB ext3 && var - /var - the rest (about 1.64GB) ext3

Check figure 10.10 to see the result:

& Click Accept.

& The Figure 10.11 shows the dasd configuration for our Linux.

& In the Installation Settings window, select Software. You might see a Disk Space Warning window. If so, click OK. & The Software Selection window opens. Leave Base System, 32-Bit Runtime Environment, Help and Support Documentation, and Minimal System selected. Clear all other setting as shown in Figure 10.12, click OK. Click the disk usage window to update the graphs.

& In the Expert tab, move down to Default Runlevel and choose 3: Full multiuser with network. Click OK. You will receive a VNC warning. Click Yes.

& You are ready to begin the installation. Click Install.

& The window Finishing Basic Installation will appear, then the VNC client will end and the system will reboot. Go back to the 3270 console and clear the screen a number of times. & Restart or go back to the same VNC client used for the first part of installation. From a browser either click Login Again or click the browser's refresh button until another VNC login window appears. If you are using a VNC client, open that application again. & Log in using the same VNC password (12345678 in this example). & In the Password for root user window, type the root password twice and click Next. Do not forget this password. & In the Hostname and Domain Name window, both Hostname and Domain Name are entered by the installer as they are specified in LINUX PARM file. In this example, linux1-titog is the host name and workshop.ibm.com is the domain name. Clear the Change Hostname via DHCP check-box. Click Next. & In the Network Configuration window you will see Firewall is enabled, click the word disable to disable it. All other values should be correct; therefore, just click Next. & In the Test Internet Connection window, if you do not have Internet access, select No, skip this test, and click Next. & In the Network Services Configuration window, accept the default and click Next. A certificate will be created. & In the User Authentication Method window, select Local (/etc/passwd) and click Next. & In the New Local User window, add at least one user to have a non-root ID on all cloned systems. When you are done, click Next. & In the Writing the system configuration window the SuSEconfig tool writes all your settings to disk. & The next window will be Release Notes. After reviewing the release notes, click Next. & In the Hardware Configuration window, choose the Skip Configuration radio button and click Next. & The last installation window is Installation Completed. Clear the box Clone This System for AutoYaST2 check box and click Finish.

The VNC session should end. Return to the 3270 session and you may have to clear the screen a few times. Then, you should see a login prompt. You are done installing Linux! You can disconnect from the 3270 session using the DISCONNECT command:

==> #cp disc

You can now access this Linux system using SSH.
