Chapter 17. 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 17.1, “Replica version requirements”
17.1. 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 17.2, “Methods for displaying IdM software version”.
17.2. 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.- 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 theipa-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
