Chapter 14. Preparing the system for IdM replica installation

The following sections list the requirements to install an Identity Management (IdM) replica. Before the installation, make sure your system meets these requirements.

A system where you want to install a replica must meet the general requirements for servers: Chapter 1, Preparing the system for IdM server installation

For additional requirements specific to replicas, see: Section 14.1, “Replica version requirements”

14.1. Replica version requirements

Red Hat Enterprise Linux (RHEL) 8 replicas only work with Identity Management (IdM) masters running on RHEL 7.4 and later. Before introducing IdM replicas running on RHEL 8 into an existing deployment, upgrade all IdM servers to RHEL 7.4 or later, and change the domain level to 1.

In addition, the replica must be running the same or later version of IdM. For example:

  • The master server is installed on Red Hat Enterprise Linux 8 and uses the IdM 4.x packages.
  • You must install the replica also on Red Hat Enterprise Linux 8 or later and use IdM version 4.x or later.

This ensures that configuration can be properly copied from the server to the replica.

For details on how to display the IdM software version, see Section 14.2, “Methods for displaying IdM software version”.

14.2. Methods for displaying IdM software version

You can display the IdM version number with:

  • the IdM WebUI
  • ipa commands
  • rpm commands

 

Displaying version through the WebUI

In the IdM WebUI, the software version can be displayed by choosing About from the username menu at the top-right.

Checking IdM Software Version
Displaying version with ipa commands

From the command line, use the ipa --version command. 

[root@server ~]# ipa --version
VERSION: 4.8.0, API_VERSION: 2.233
Displaying version with rpm commands

If IdM services are not operating properly, you can use the rpm utility to determine the version number of the ipa-server package that is currently installed. 

[root@server ~]# rpm -q ipa-server
ipa-server-4.8.0-11.module+el8.1.0+4247+9f3fd721.x86_64
