Installing the SAP HANA Software

Prerequisites

• You have prepared related resources. For details, see section "Preparing Resources".
• You have created ECSs, formatted disks attached to them, and completed required configurations.
• Ensure that the OS firewall of the new node is disabled. For details about how to disable the OS firewall, see Modifying OS Configurations.

Procedure

1. Log in at https://support.sap.com/swdc to download the installation package, and perform the installation.
   1. Switch to SAP Software Download Center.
      • Choose Software Downloads.
      • Choose INSTALLATIONS & UPGRADES.
      • Choose By Alphabetical Index (A-Z).
      • Choose H.
      • Choose SAP HANA PLATFORM EDITION.
      • Choose DOWNLOADS.
   2. Locate the target package and download it to the local hard disk.
   3. Upload the obtained installation package to the /hana/shared directory on the ECS where the SAP HANA software is to be installed and decompress it. For example, the installation package is

      51052383_part1.exe

      cd /hana/shared

      unrar x 51052383_part1.exe

   4. Run the following command to enter the directory where the installation file is stored, taking SAP_HANA_DATABASE as an example:

      For example, if the installation file is stored in /DATA_UNITS/HDB_SERVER_LINUX_X86_64, run the following commands:

      cd 51052383

      cd DATA_UNITS/HDB_SERVER_LINUX_X86_64

   5. Run the following command to assign execute permissions to the directory:

      chmod -R 777 /hana

   6. Run the following command to perform the installation:

      ./hdblcm --ignore=check_signature_file

      The following information is displayed:

      Choose installation
      
        Index | System             | Database Properties
        ------------------------------------------------
        1     | Install new system  |
              |      
        2     | Extract components  |
        3     | Exit (do nothing)   |

   7. Enter 1 and press Enter.

      The following information is displayed:

      Select additional components for installation:
      
        Index | Components | Description
        ---------------------------------------------
        1     | server     | No additional components
        2     | all        | All components
      
      Enter comma-separated list of the selected indices [1]:
   8. Enter 1 and press Enter.
   9. Configure parameters as prompted on the page one by one.
      NOTE:

      • During the configuration, press Enter if you want to retain the default setting.
      • If a parameter is incorrectly set and you have pressed Enter, you can press Ctrl+C to exit the configuration and run the ./hdblcm --ignore=check_signature_file command to enter the installation page again.

      Table 1 lists the parameter configuration requirements.

      Table 1 Requirements for configuring SAP HANA installation parameters

      Parameter	Description
      Installation Path	Specifies the installation path, which defaults to /hana/shared/$SID. The default value is recommended.

      Do you want to add additional hosts to the system	Enter the value n.
      SAP HANA System ID	Specifies the SAP HANA system ID, for example, S00.
      Instance Number	Specifies the SAP HANA instance number, for example, 00. The instance ID is used in Security Group Rules, which must be the same as the planned one.
      Database Mode	Specifies the database deployment mode. Retain the default value single_container. You do not need to set this parameter when installing HANA2.0 and the default value is multiple container.
      System Usage	Specifies the SAP HANA system type. Set this parameter as required. This parameter is stored in the global.ini file.
      Location of Data Volumes Specifies	Specifies the system data volume directory, which is /hana/data/$SID.
      Location of Log Volumes	Specifies the system log volume directory, which is /hana/log/$SID.
      Restrict maximum memory allocation?	Specifies whether maximum memory allocation is restricted, which defaults to n.
      Certificate Host Name	Specifies the ECS name that is used to generate a self-signed SSL certificate for the SAP Host Agent.
      SAP Host Agent User (sapadm) Password	Enter the SAP Host Agent user password.
      System Administrator (s00adm) Password	Enter the system administrator password.
      System Administrator Home Directory	Use the default value.
      System Administrator Login Shell	Use the default value.
      System Administrator User ID	Use the default value.
      ID of User Group	Use the default value.
      Database User (SYSTEM) Password	Enter the database user password.

   10. After you complete the configuration, the system displays the message "Restart system after machine reboot?"
       • In single-node scenarios where HA is not required, enter y.
       • In single-node scenarios where HA is required, if automatic active/standby switchover is not required, enter y; if automatic active/standby switchover (HAE) is required, enter n.

       Then, press Enter. The system displays the installation summary.

   11. After confirming the installation information is correct, in the Do you want to continue? dialog box, enter y and press Enter to start to installation.

       After the installation is complete, the prompt Installation done is displayed.

2. Verify the installation.
   1. Run the following command to switch to the /hana/shared/$SID/HDB00/ directory:

      The following command is used as an example:

      cd /hana/shared/S00/HDB00

   2. Switch to the database system administrator.

      Account s00adm is displayed on the page during the installation. Run the following command:

      su - s00adm

   3. Run the following command to query the database version:

      If the version can be queried, the database software is installed.

      HDB -version

      After the database is installed, the system returns the version. Figure 1 shows an example.

      Figure 1 SAP HANA version information
      

3. Check whether the database process is running properly.
   1. Run the following command to check the process, taking the SAP HANA instance with ID 00 as an example:

      sapcontrol -nr 00 -function GetProcessList

      In the terminal display, if the dispstatus value is GREEN, the process is running properly.

   2. Run the following command to return to user root:

      exit

4. Switch to the other SAP HANA node using SSH and install the SAP HANA software on it by repeating 1 to 3.

   During the software installation, ensure that the installation information of this HANA ECS is the same as that of the previous HANA ECS, excepting the host name.
