[SoftNAS KB]: Setup NTPD on CentOS Linux


Server is not keeping the correct time.


SoftNAS needs persistent time settings to be accurate for HA and replication and the wrong time or timezone can potentially cause issues.


Open the terminal or login over the ssh session. You must login as as the root user. Type the following yum command to install NTP:

  # yum install ntp ntpdate ntp-doc

Turn on service, enter:

  # chkconfig ntpd on

Synchronize the system clock with 0.pool.ntp.org server (use this command only once or as required):

  # ntpdate pool.ntp.org

Start the NTP server. The following will continuously adjusts system time from upstream NTP server. No need to run ntpdate:

  # /etc/init.d/ntpd start

Additional Information

Configure ntpd (optional)

Edit /etc/ntp.conf, enter:

  # vi /etc/ntp.conf

Set public servers from the pool.ntp.org project:

  server 0.rhel.pool.ntp.org

  server 1.rhel.pool.ntp.org

  server 2.rhel.pool.ntp.org
