After you have set the hostname, you should add an entry within the server’s hosts file. Concern the command:
sudo nano /and so forth/hosts
Add a line on the backside like this:
The place SERVER_IP is the IP tackle of the server and HOSTNAME is the FQDN of the server.
Save and shut the file.
How you can set up FreeIPA
The set up of FreeIPA begins with enabling the idm:DL1 repository with the command:
sudo module allow idm:DL1
When that command completes, sync the repository with the command:
sudo dnf distro-sync
Set up FreeIPA with the command:
sudo dnf set up ipa-server ipa-server-dns -y
How you can arrange FreeIPA Server
Subsequent it’s a must to run the configuration script for FreeIPA Server. To try this, situation the command:
The primary query you should reply is whether or not or not you need to set up BIND for DNS. Settle for the default (no) by urgent Enter in your keyboard. You could then affirm the area and realm identify, which can each be detected by the script. As soon as you have confirmed these entries, you may have to set a listing supervisor password, an IPA admin password for the online interface, after which settle for the default (no) for the set up of chrony.
After you have taken care of the above, you may be offered with the main points of your set up (Determine A).
Kind y and hit Enter in your keyboard. The configuration will start. This does take a little bit of time, so both sit again and watch the textual content fly by or set about to deal with one other activity.

Open a browser and level it to https://SERVER_IP (the place SERVER IP is the IP tackle of the internet hosting server). Try to be prompted for a username and password (Determine B). The username is admin and the password is the one you set for IPA admin in the course of the configuration.
Upon profitable login, you may end up on the FreeIPA important window, the place you may start managing your centralized authentication server (Determine C).
And that is all there’s to getting FreeIPA put in on CentOS. Now you can spend a while including customers and different bits to make your id and authorization resolution work for your online business.
