Before attempting to install or remove the Apache Recovery Kit, you must understand the hardware and software requirements for the package and the installation and removal procedures.
Kit Hardware and Software Requirements
Before installing and configuring the Apache Recovery Kit, be sure that your configuration meets the following requirements:
- Servers. The Recovery Kit requires two or more supported computers configured in accordance with LifeKeeper requirements described in the LifeKeeper for Linux Technical Documentation and the LifeKeeper for Linux Release Notes, which are located on our SIOS Technical Documentation site at docs.us.sios.com.
- LifeKeeper software. You must install the same version of LifeKeeper software and any patches on each server. Please refer to the LifeKeeper for Linux Release Notes and LifeKeeper for Linux Technical Documentation for specific LifeKeeper requirements.
- LifeKeeper IP Recovery Kit. You must have the same version of this Recovery Kit on each server.
- IP network interface. Each server requires at least one Ethernet TCP/IP-supported network interface. In order for IP switchover to work properly, user systems connected to the local network should conform to standard TCP/IP specifications.
- TCP/IP software. Each server also requires the TCP/IP software.
- Apache software. Each server must have the Apache HTTP Server software installed and configured prior to configuring the Apache Recovery Kit, including any DSO (Dynamic Shared Object) modules that will be used. The same version of all Apache HTTP Server software packages should be installed on each server. Refer to the LifeKeeper for Linux Support Matrix for supported software versions.
