====== NTP Start Issue ======
<color darkorange>Apr 2021</color>
\\ 
\\ 
\\ 

This was created and tested using CentOS 7.9
----
I recently had an issue where NTP would not start on a server, I have no idea why, it had CentOS installed and configured exactly the same as the other servers in the system, however NTP would not start.
\\ 
\\ 
Running <color #ed1c24>ntpstat</color> I would see that the server was <color #ed1c24>unsynchronised</color>. 
\\ 
\\ 
Using timedatectl I could see the following:
\\ 
<file>
      Local time: Thu 2021-04-08 14:22:37 UTC
  Universal time: Thu 2021-04-08 14:22:37 UTC
        RTC time: Thu 2021-04-08 14:22:37
       Time zone: UTC (UTC, +0000)
     NTP enabled: no
NTP synchronized: no
 RTC in local TZ: no
      DST active: n/a
</file>
\\ 
NTP enabled: <color #ed1c24>no</color>\\ 
NTP synchronized: <color #ed1c24>no</color>\\ 
\\ 
\\ 
From the command line, issue the command:
\\ 
\\ 
    timedatectl set-ntp yes
\\ 
\\ 
Re-run the <color #ed1c24>timedatectl</color> command and you should see:
\\ 
<file>
      Local time: Thu 2021-04-08 14:23:20 UTC
  Universal time: Thu 2021-04-08 14:23:20 UTC
        RTC time: Thu 2021-04-08 14:23:20
       Time zone: UTC (UTC, +0000)
     NTP enabled: yes
NTP synchronized: yes
 RTC in local TZ: no
      DST active: n/a
</file>
\\ 
where:
\\ 
\\ 
NTP enabled: <color #22b14c>yes</color>\\ 
NTP synchronized: <color #22b14c>yes</color>\\
