NTP (Network Time Protocol) Setup for Linux (Ubuntu) Server

#linux #ubuntu #ntp #timezone

When you launch a new Linux server, whether it's an AWS EC2 instance or a local server, by default, the server time is not synced with the NTP server and most of the times the timezone is set to UTC.

In most cases server timing synchronizing with the NTP server is very important.

Following are the steps:

sudo apt-get install ntp
Enter fullscreen mode Exit fullscreen mode
  • Open the ntp.conf file: 
sudo vi /etc/ntp.conf

pool 0.ubuntu.pool.ntp.org iburst
pool 1.ubuntu.pool.ntp.org iburst
pool 2.ubuntu.pool.ntp.org iburst
pool 3.ubuntu.pool.ntp.org iburst
Enter fullscreen mode Exit fullscreen mode
  • Restart the NTP service 
sudo service ntp restart
Enter fullscreen mode Exit fullscreen mode
  • Check the NTP service status by running the following command: 
service ntp status
Enter fullscreen mode Exit fullscreen mode
