Configure NTP server using Chrony on RHEL 8

1. Install Chrony (if not already installed):

You can install Chrony using the package manager dnf. Run the following command in your terminal:

#sudo dnf install chrony

2. Edit the Chrony Configuration File:

Open the Chrony configuration file /etc/chrony.conf in a text editor with root privileges. You can use nano, vim, or any other editor you prefer.

#sudo vim /etc/chrony.conf

3. Configure NTP Servers:

In the chrony.conf file, you’ll find a section where you can specify NTP servers. Locate the server directive and add your NTP server(s) to it. You can comment out existing servers or add new ones. For example: Replace ntp.example.com with the address of the NTP server you want to use.

server time.nplindia.org iburst

4. Restart Chrony:

After making changes to the configuration file, restart the Chrony service to apply the changes:

#sudo systemctl restart chronyd

5. Verify Configuration:

You can verify that Chrony is synchronizing with the new NTP server(s) by checking its status:

#chronyc sources -v

This command will display information about the currently configured NTP sources and their synchronization status.

That’s it! You have now set a new NTP server using Chrony on RHEL 8. Make sure to choose reliable NTP servers for accurate time synchronization.
