Installing and Configuring Network Time Protocol (NTP) on Ubuntu

Install and configure NTP on Ubuntu

Enter the following command to install NTP:

sudo apt-get install ntp

Use NTP pool servers

1. Open /etc/ntp.conf in a text editor.
2. Look for lines similar to the following:

server 0.centos.pool.ntp.org
server 1.centos.pool.ntp.org
server 2.centos.pool.ntp.org

3. Replace those lines or add additional lines that specify your NTP pool server or other NTP servers. It’s a good idea to specify more than one.
4. An example of using three United States-based NTP servers follows:

server 0.us.pool.ntp.org
server 1.us.pool.ntp.org
server 2.us.pool.ntp.org

5. Save your changes to /etc/ntp.conf and exit the text editor.
6. Restart the service.

sudo service ntp restart

7. Enter date to check the server’s date.
