Configure NTP in Linux

1. Check the current configuration of NTP server with the below command.
   ntpq -p
2. If the server is not setup with NTP server, edit /etc/ntp.conf

• Add the NTP server IP Address to the ntp configuration file

server 10.11.01.88 iburst

• Comment or remove the existing lines starting with ‘server’ from the configuration file

# server 0.rhel.pool.ntp.org iburst

# server 1.rhel.pool.ntp.org iburst

# server 2.rhel.pool.ntp.org iburst

# server 3.rhel.pool.ntp.org iburst
