This document will guide you through the installation of the LifeKeeper Single Server Protection Software (SSP) and assumes the user has basic knowledge of the Linux operating system. Please refer to the LifeKeeper Single Server Protection Software for Linux product documentation for more information.

Pre-Installation Requirements

Before installing SSP for Linux, please check the following:

  • SSP for Linux Release Notes -The Release Notes include supported platforms, operating systems, applications, and storage. They also include the latest features and Bug Fixes.
  • TCP/IP Connection and Name Resolution – In order to use the GUI function, both cluster nodes need to be able to resolve the name. Use the DNS service or /etc/hosts for name resolution. Also, localhost needs to be resolved to 127.0.0.1.
  • Firewall – The following ports are used:
    • Communication Path (TCP): 7365/tcp
    • Communication of a GUI Server: 81/tcp、82/tcp
    • RMI Communication between the GUI Server and Client: all the ports after 1024/tcp
More Firewall Information
  • The port used for communication with the GUI server and a client needs to be open on the cluster node where SSP is installed and on all systems where the GUI client runs.
  • For communication between the GUI server and a client, Java RMI (Remote Method Invocation) randomly uses ports 1024 and above. Please refer to the Technical Documentation for the setting details.
  • Add the following to the port numbers you are using: WebGUI server process and policy setting with the lkpolicy command : 778(SSL) /tcp
    • Check the SELinux Setting – When the SELinux setting is enabled, SSP for Linux may not be able to be installed depending on the mode.
      • enforcing mode – SSP for Linux cannot be installed
      • permissive mode – SSP for Linux can be installed (not recommended except in some ARK environments)
        • It is not recommended to use SELinux permissive mode unless it is required in an SAP environment. Please make sure that the application to be run on the cluster supports permissive mode. SELinux permissive mode has been tested for following ARKs: SAP MaxDB / Sybase / Oracle / DB2 / NFS / NAS / IP / FileSystem / MQ. Refer to Linux Dependencies for required packages.
      • disabled mode – SSP for Linux can be installed
        • Please refer to the OS distribution documentation on how to disable SELinux.
      • Install the appropriate package provided by your distribution.
    • Check Known Issues – Please make sure that there are no known issues for your environment.

Installing SSP for Linux

Install the LifeKeeper Single Server Protection software on each server in the LifeKeeper Single Server Protection configuration.

​Packages that LifeKeeper is dependent on are installed automatically because the LifeKeeper installation setup script uses package manager tools (yum or zypper) to ensure installation of all dependent packages.

The LifeKeeper Single Server Protection image file (lkssp.img) provides a set of installation scripts designed to perform the user interactive system setup tasks that are necessary when installing SSP on your system (see Interactive Mode for more information). A non-user interactive install can be performed as well (see Non-interactive Mode for more information).

A licensing utilities package is also installed providing utilities for obtaining and displaying the Host ID or Entitlement ID of your server. Host IDs and/or Entitlement IDs are used to obtain valid licenses for running LKSSP.

Please refer to How to Use Setup Scripts for the installation activities.

For upgrading, please refer to Upgrading SSP.
