FreeIPA is an open-source authentication and identity management system designed for Linux/Unix-based environments. In this tutorial, we’ll show you how to install FreeIPA on POP! OS Latest.

Prerequisites

A server running POP! OS Latest
A user account with sudo privileges

Step 1: Install the FreeIPA Repo

The first step is to install the FreeIPA repository on your POP! OS Latest server. You can do this by running the following command:

$ sudo apt install freeipa-client -y

This will download and install the FreeIPA repository for you.

Step 2: Configure System Hostname

Before proceeding to install FreeIPA, you need to set the hostname of your system using the command below:

$ sudo hostnamectl set-hostname ipa.example.com

Replace "ipa.example.com" with your desired hostname.

Next, run the following command to set the hostname of your system in the /etc/hosts file:

$ sudo sh -c 'echo "<YOUR_SERVER_IP> ipa.example.com ipa" >> /etc/hosts'

Replace "" with your server IP address.

Step 3: Install FreeIPA Server Package

Run the following command to install the FreeIPA server package:

$ sudo apt install freeipa-server -y

During the installation, you will be prompted to configure your server as an IPA server. Answer "Yes" and provide a password for the Directory Manager.

Step 4: Configure Firewall Rules

Next, enable the ports required by FreeIPA by running the following command:

$ sudo firewall-cmd --add-port={53/tcp,53/udp,88/tcp,88/udp,389/tcp,389/udp,636/tcp,464/tcp,464/udp,88/tcp} --permanent

Then, reload the firewall configuration:

$ sudo firewall-cmd --reload

Step 5: Configure DNS

FreeIPA requires a working DNS server installed on your system. You can use bind as your DNS server.

To install and configure the bind DNS server, run the following commands:

$ sudo apt install bind9 -y
$ sudo rndc-confgen >> /etc/rndc.conf
$ sudo chown root:named /etc/rndc.conf
$ sudo chmod 640 /etc/rndc.conf
$ sudo systemctl start bind9
$ sudo systemctl enable bind9

To configure the FreeIPA server, run the following command:

$ sudo ipa-server-install --setup-dns --forwarder=8.8.8.8 -a <YOUR_PASSWORD>

Replace "" with your desired password.

This command will begin the installation process and configure your FreeIPA server.

Step 7: Verify FreeIPA Installation

To verify the installation, run the following command:

$ sudo ipactl status

This command will confirm that the FreeIPA server is running and that all services are started.
