Installing RHEL 10 for SAP Solutions

1. Install RHEL 10 using one of the standard Red Hat Enterprise Linux 10 installation ISO images.

2. Install additional packages needed for running SAP software, either

   • from another repository source, for example, a Red Hat Satellite system, or

   • from the RHEL 10 for SAP Solutions image, which contains only a set of additional packages needed for SAP.

     Note

     There are also ISO images named Red Hat Enterprise Linux for SAP Solutions, but those only contain the additional software packages required to be installed on top of Red Hat Enterprise Linux. It is not possible to install RHEL for SAP Solutions from these ISO images.

Procedure

1. Download the Katello client rpm package:

   # wget https://sat.int.example.com/pub/katello-ca-consumer-latest.noarch.rpm

   Replace the URL with the URL provided by your Satellite administrator.

2. Install the Katello client rpm package:

   # dnf install -y katello-ca-consumer-latest.noarch.rpm

   Replace the package name with the name of the package you downloaded.

3. Register your system:

   # subscription-manager register --org="your-organization-name" \
   --activationkey="your-activation-key"

   Replace your-organization-name with the string representing the name of the organization and replace your-activation-key with the activation key. Both are provided by your Satellite administrator.

Procedure

1. Clear the dnf cache:

   # rm -rf /var/cache/dnf

2. Set the release lock:

   # subscription-manager release --set=10.x

   Replace 10.x with the supported minor release of RHEL 10 (for example 10.0).
   

Procedure

1. Make a backup of the system if you would like to preserve the original configuration of the server.
2. Configure your name resolution and /etc/hosts settings according to your desired configuration. The RHEL System Roles for SAP can also be used to maintain your /etc/hosts file (using the parameters sap_domain and sap_general_preconfigure_modify_etc_hosts) but for simplicity, we assume that your name resolution and the content of /etc/hosts are configured already.
3. Ensure that your release lock is set according to your needs and that you have enabled the desired repositories. The RHEL System Roles for SAP can also be used to set the release lock and enable the repos but for simplicity, we assume that these configuration settings are already done.

4. Create a file named sap-vars.yml with the content in the code block below. It updates your system to the latest patch level. If this is not desired, set sap_general_preconfigure_update and sap_hana_preconfigure_update to false, comment out these lines by prepending them with #, or remove these two lines:

   ---
   
   sap_general_preconfigure_update: true
   sap_general_preconfigure_fail_if_reboot_required: false
   sap_netweaver_preconfigure_fail_if_reboot_required: false
   sap_hana_preconfigure_update: true
   sap_hana_preconfigure_fail_if_reboot_required: false

5. Run the following command:

   # ansible-playbook redhat.sap_install.sap_hana_preconfigure_exec.yml -e @sap-vars.yml

   This configures this system according to the applicable SAP notes for SAP HANA on RHEL 10.

6. After the ansible-playbook command has finished, reboot the system:

   # reboot

5. Create a file named sap-abap.yml with the following content:

   ---
   
   - hosts: localhost
     collections:
       - redhat.sap_install
     become: true
     roles:
       - sap_general_preconfigure
       - sap_netweaver_preconfigure

   # ansible-playbook sap-abap.yml -e @sap-vars.yml

       - sap_hana_preconfigure

6. Run the following command:

   # ansible-playbook sap-hana_abap.yml -e @sap-vars.yml

   This configures this system according to the applicable SAP notes for SAP HANA on RHEL 10. Run the role sap_hana_preconfigure after the role sap_netweaver_preconfigure to ensure the configuration of certain specific settings for SAP HANA (e.g. kernel tunables).

7. After the ansible-playbook command has finished, reboot the system:

   # reboot
