FreeIPA is an open-source identity management solution that provides centralized authentication, authorization, and account information for Linux systems. It integrates several technologies such as Kerberos, LDAP, DNS, and certificate management. In this guide, we will walk through the steps to install FreeIPA on Rocky Linux.

Step 1: Update Your System

Before starting the installation, ensure that your system is up to date. Open a terminal and run:

sudo dnf update

Step 2: Install Required Packages

Install the required packages for FreeIPA by executing the following command:

sudo dnf install freeipa-server freeipa-client

Step 3: Configure the Firewall

FreeIPA requires certain ports to be open in the firewall. Run the following commands to allow necessary services:

sudo firewall-cmd --permanent --add-service=freeipa
sudo firewall-cmd --permanent --add-service=ldap
sudo firewall-cmd --permanent --add-service=kerberos
sudo firewall-cmd --permanent --add-service=dns
sudo firewall-cmd --reload

Step 4: Set Hostname

FreeIPA should be installed on a host with a fully qualified domain name (FQDN). Set the hostname using:

sudo hostnamectl set-hostname your_hostname.example.com

Step 5: Run FreeIPA Installation

To begin the FreeIPA installation, run the following command, replacing your_hostname.example.com with your actual FQDN:

sudo ipa-server-install --setup-dns --hostname=your_hostname.example.com

You will be prompted to provide information such as the realm name, admin password, and directory manager password during the installation. Follow the on-screen instructions to complete the setup.

Step 6: Start FreeIPA Services

After the installation, ensure that all FreeIPA services are running properly:

sudo systemctl start ipa
sudo systemctl enable ipa

Step 7: Verify the Installation

To verify that FreeIPA is running correctly, access the web interface by navigating to:

https://your_hostname.example.com/ipa/ui

Log in using the admin credentials you set during the installation process.
