Ticket 193 ‐ Configure Time Synchronization Across Servers Using Puppet - SupaHotBall/OE2-Group-D GitHub Wiki

Task

  • Create Puppet Manifest:

  • Develop a Puppet manifest to configure time synchronization on all servers.

  • Use the appropriate Puppet module to manage time settings.

  • Apply Configuration:

  • Apply the Puppet manifest to all servers.

  • Ensure the time synchronization service is running and configured correctly.

Steps Taken

Create the Puppet module structure for the ntp service module (/etc/puppetlabs/code/modules/ntp_service) on the management server.

image

sudo mkdir ntp_service
sudo mkdir ntp_service/manifests
sudo mkdir ntp_service/files
sudo mkdir ntp_service/templates

Create the init.pp file in the manifests subdirectory

sudo nano init.pp

image

Edit the init.pp file with the code for managing NTP

image

Retrieve the template file and place it in the templates directory

image

Apply the module to all puppet nodes in the site.pp file located at /etc/puppetlabs/code/environments/production/manifests/

include ntp_service

image

Repeat steps below for all servers - db, apps and backup

Run the puppet agent on each machine to apply the configuration

sudo puppet agent --server=mgmt-d --no-daemonize --verbose --onetime

image

Verify that the ntp service is running

sudo systemctl status ntp

image

Check for ntp synchronization

ntpq -p

image

Check the time accuracy between the agents and the master are consistent within milliseconds.
