How to Install FreeIPA Server on RHEL 8 | Rocky Linux 8 | AlmaLinux 8
|
||||
======
|
||||
|
||||
Are you looking for an easy guide on how to install FreeIPA server on Linux ?
|
||||
|
||||
The step-by-step guide on this page will show how to install FreeIPA server on RHEL 8 , Rocky Linux 8 and AlmaLinux 8.
|
||||
|
||||
[FreeIPA][1]is a free and open source centralized identity and access management tool for Linux-based systems, it is the upstream project for Red Hat identity manager. Using FreeIPA, we can easily manage centralized authentication along with account management, policy (host-based access control) and audit.
|
||||
|
||||
FreeIPA is based on the following Open Source projects,
|
||||
|
||||
- LDAP Server – based on the 389 project
|
||||
- KDC – based on MIT Kerberos implementation
|
||||
- PKI based on Dogtag project
|
||||
- Samba libraries for Active Directory integration
|
||||
- DNS Server based on BIND and the Bind-DynDB-LDAP plugin
|
||||
- NTP
|
||||
|
||||
##### Prerequisites
|
||||
|
||||
- Pre Installed RHEL 8 or Rocky Linux 8 or AlmaLinux 8
|
||||
- Sudo User with admin rights
|
||||
- RAM = 2 GB
|
||||
- CPU =2 vCPU
|
||||
- Disk = 12 GB free space on /
|
||||
- Internet connectivity
|
||||
|
||||
##### Lab Details for FreeIPA
|
||||
|
||||
- IP Address = 192.168.1.102
|
||||
- Hostanme = ipa.linuxtechi.lan
|
||||
- OS: RHEL 8 or Rocky Linux 8 or AlmaLinux 8
|
||||
|
||||
Without further ado, let’s deep dive into FreeIPA installation steps,
|
||||
|
||||
### 1) Set Hostname and Install Updates
|
||||
|
||||
Open the terminal of your server and set the hostname using hostnamectlcommand,
|
||||
|
||||
```
|
||||
$ sudo hostnamectl set-hostname "ipa.linuxtechi.lan"
|
||||
$ exec bash
|
||||
```
|
||||
|
||||
Install updates using yum/dnf command and then reboot it
|
||||
|
||||
```
|
||||
$ sudo dnf update -y
|
||||
$ sudo reboot
|
||||
```
|
||||
|
||||
### 2) Update the hosts file & Set SELinux as Permissive
|
||||
|
||||
Run the below tee command to update /etc/hosts file, replace the ip address and hostname as per your setup.
|
||||
|
||||
```
|
||||
$ echo -e "192.168.1.102\tipa.linuxtechi.lan\t ipa" | sudo tee -a /etc/hosts
|
||||
```
|
||||
|
||||
Set the selinux as permissive, run following commands,
|
||||
|
||||
```
|
||||
$ sudo setenforce 0
|
||||
$ sudo sed -i 's/^SELINUX=.*/SELINUX=permissive/g' /etc/selinux/config
|
||||
]$ getenforce
|
||||
Permissive
|
||||
$
|
||||
```
|
||||
|
||||
### 3) Install FreeIPA and its Components
|
||||
|
||||
FreeIPA packages and its dependencies are available in the Appstream package repositories. As we are planning to install integrated DNS of FreeIPA, so we will also install “ipa-server-dns & bind-dyndb-ldap”
|
||||
|
||||
Run the below command to install FreeIPA and its dependencies
|
||||
|
||||
```
|
||||
$ sudo dnf -y install @idm:DL1
|
||||
$ sudo dnf install freeipa-server ipa-server-dns bind-dyndb-ldap -y
|
||||
```
|
||||
|
||||
### 4) Start FreeIPA Installation
|
||||
|
||||
Once FreeIPA package and it’s dependencies are installed successfully then use the below command to start the freeipa installation setup,
|
||||
|
||||
It will prompt couple of things like to configure Integrated DNS, Host name, Domain Name and Realm Name.
|
||||
|
||||
```
|
||||
$ sudo ipa-server-install
|
||||
```
|
||||
|
||||
Output of above command would be something like below
|
||||
|
||||
After pressing yes in above window, it will take some time to configure your FreeIPA server and once it has been setup successfully then we will get output something like below,
|
||||
|
||||
Above output confirms that FreeIPA has been installed successfully.
|
||||
|
||||
### 5) Allow FreeIPA ports in Firewall
|
||||
|
||||
In case OS firewall is running on your server then run beneath firewall-cmd commands to allow FreeIPA ports,
|
||||
|
||||
```
|
||||
$ sudo firewall-cmd --add-service={http,https,dns,ntp,freeipa-ldap,freeipa-ldaps} --permanent
|
||||
$ sudo firewall-cmd --reload
|
||||
```
|
||||
|
||||
### 6) Access FreeIPA admin portal
|
||||
|
||||
Execute the below ipactl command to check whether all services of FreeIPA are running or not
|
||||
|
||||
```
|
||||
[[email protected] ~]$ ipactl status
|
||||
You must be root to run ipactl.
|
||||
[[email protected] ~]$ sudo ipactl status
|
||||
Directory Service: RUNNING
|
||||
krb5kdc Service: RUNNING
|
||||
kadmin Service: RUNNING
|
||||
named Service: RUNNING
|
||||
httpd Service: RUNNING
|
||||
ipa-custodia Service: RUNNING
|
||||
pki-tomcatd Service: RUNNING
|
||||
ipa-otpd Service: RUNNING
|
||||
ipa-dnskeysyncd Service: RUNNING
|
||||
ipa: INFO: The ipactl command was successful
|
||||
[[email protected] ~]$
|
||||
```
|
||||
|
||||
Let’s verify whether admin user will get token via Kerberos using the kinit command, use the same password of admin user that we supplied during FreeIPA installation.
|
||||
|
||||
```
|
||||
$ kinit admin
|
||||
$ klist
|
||||
```
|
||||
|
||||
Output of above commands,
|
||||
|
||||
Perfect, output above confirms that admin gets the token. Now, try to access FreeIPA Web Console, type following url on web browser,
|
||||
|
||||
https://ipa.linuxtechi.lan/ipa/ui
|
||||
|
||||
or
|
||||
|
||||
https://<Server-IPAddress>/ipa/ui
|
||||
|
||||
Use the user name as admin and the password that we specify during the installation.
|
||||
|
||||
For FreeIPA web console, self-signed ssl certificates are used that’s why we got this window, so click on “Accept the Risk and Continue”
|
||||
|
||||
After entering the credentials, click on ‘Log in‘
|
||||
|
||||
This confirms that we have successfully setup FreeIPA on RHEL 8/Rocky Linux 8 / AlmaLinux8.
|
||||
|
||||
That’s all from this, I hope you have found it informative. Kindly do post your queries and feedback in below comments section.
