This is a guided installation of the operating system with optimized settings for SAP applications.
During this installation scenario, the following installation and configuration steps will take place. Interactive settings are required or possible. At the end of the SUSE Linux installation, you will be prompted to insert your SAP product media.
The following data is required for the SUSE Linux Enterprise Server part of the installation (required per physical server):
Domain searchlist (DNS)
IP for nameserver
IP for gateway
Master password for the system installation (root password)
Some more specific parameters are required depending on the SAP
application you want to install, for example
System T-Shirt Sizing.
From the DVD boot menu (see Figure 2-1), select . The installation process loads and configures a SUSE Linux system with all requirements for a SAP installation. To view the boot messages and copyright notices during this process, press Esc. On completion of this process, the YaST installation program starts and displays the graphical installer, which will run mostly automatically.
On the initial dialog confirm the license (see Figure 2-2).
After analyzing your computer, YaST allows you to specify options for a customized installation.
First, YaST prompts you to enter the system administrator password; see Figure 2-4. This is the root password for the system.
Figure 2-4 System Administrator Password
root is the name of the superuser, or the administrator of the system. Unlike regular users (who may or may not have permission to access certain areas or execute certain commands on the system), root has unlimited access to change the system configuration, install programs, and set up new hardware. The root account should only be used for system administration, maintenance, and repair. Logging in as root for daily work is rather risky: a single mistake could lead to irretrievable loss of system files.
For verification purposes, the password for root must be entered twice. Do not forget the root password. Once entered, this password cannot be retrieved.
The root password can be changed any time later in the installed system. To do so, run YaST and start .
WARNING: The root User
The root user has all the permissions needed to make changes to the system. To carry out such tasks, the root password is required. You cannot carry out any administrative tasks without this password.
The next YaST pop-up dialog lets you fine-tune the volume configuration. Here you configure the volume for the system and swap space. Suitable values depending on your available hardware are pre-selected. This is for the SUSE Linux operating system only; the data volume comes later, after selecting the SAP Application.
Figure 2-5 System Volume Configuration
If there is just one hard disk, keep it as the system volume device and set the size of the system volume (and the swap space) in GB in the lower field and confirm it; see Figure 2-5.
HINT: Size of the System Volume
Normally, at least 35 GB is required for the system volume. The swap space depends on the available main memory (RAM). For more information, see the SAP Note 1984787: https://service.sap.com/sap/support/notes/1984787.
If there is more than one hard disk, select the right one as the system volume device and set the size of the system volume (and the swap space) in GB in the lower fields and confirm it. For more information about partitioning, see Section 3.0, Background Information on Partitioning.
WARNING: Deleting Data
If you confirm the storage volume configuration, all existing data on the hard disk will be deleted. If you do not want this to happen, turn off the system.
The next dialog starts with the network configuration; see Figure 2-6.
Figure 2-6 Hostname, Domain Name, and IP Address
HINT: Querying DHCP Server
The installation wizard will query a locally running DHCP server to get interesting network data such as names and IP adresses for the local host, DNS server, NTP server, etc. This ensures that the entry fields of the next dialogs will be prefilled with these data.
Theis the computer’s name in the network. The is the name of the network. A hostname and domain are proposed by default. If your system is part of a network, the hostname has to be unique in this network, whereas the domain name has to be common to all hosts on the network.
Also enter theand for this host. The IP address must be unique and the netmask has to be common to all hosts on the network.
The next dialog continues with the network configuration; see Figure 2-7.
Figure 2-7 Domain Name Service (DNS) and Time Server (NTP)
For Domain Name Service (DNS) configuration, enter theand the plus the IP address of the of your network.
Also enter the address of theto synchronize automatically via Network Time Protocol (NTP).
To get technical support and product updates, you need to register and activate your product with the Novell Customer Center; see Figure 2-8. This dialog provides assistance for doing so. For information about SUSE Customer Center, see https://scc.suse.com.
Figure 2-8 Registration
Enter yourand for the product. If you provide the registration code now, operating system updates will be installed automatically during the installation of the system.
NOTE: Additional Packages Pre-Selected
If you install with registration, the SUSE Linux Enterprise High Availability Extension repository by default will be activated and some few SUSE Linux Enterprise High Availability Extension packages will get installed. This will not happen, if you will register the product after the installation.
After confirmation, the system will be configured with the supplied settings. Then YaST performs the partitioning and the software installation. Packages are installed one by one, so you can see the progress.
No user action is required at this stage.
WARNING: Firewall Disabled
This wizard-based installation scenario disables the firewall (SuSEfirewall2) completely.
If needed, you can activate the firewall after the installation. If you activate the firewall after the installation, you must open all required ports manually. For more information about required ports, see Section 5.2.2, Ports Configuration.
After an automatic reboot () and applying previously supplied configuration settings, you are prompted to continue with the using the SAP Installation Wizard. The SAP Installation Wizard will install the SAP application from the SAP media kits you received from SAP.
HINT: SAP Product Installation Default Settings
The SAP Product Installation default settings are specified and documented in /etc/sysconfig/sap-installation-wizard. You can change them according to your needs.
Select Figure 2-9) if you want to continue with the installation right away.and confirm the pop-up (see
Otherwise, it is possible to just prepare the SAP product installation with, or completely interrupt the installation process at this point with and resume it after a system restart.
