Replacement of ntp with chrony
In Oracle Linux 8 and later, chrony replaces ntp for the management of NTP. The following table shows file, command, and terminology equivalents between ntp and chrony.
| ntp | chrony |
|---|---|
/etc/ntp.conf
|
/etc/chrony.conf
|
/etc/ntp/keys
|
/etc/chrony.keys
|
ntpd
|
chronyd
|
ntpq command
|
chronyc command
|
ntpd.service
|
chronyd.service
|
ntp-wait.service
|
chrony-wait.service
|
ntpdate and sntp utilities
|
chronyd -q and chronyd -t commands
|
The ntpstat utility which is available in the ntpstat package, now supports chronyd. Thus, you can still use the utility in Oracle Linux 8 and later. The command generates output that's similar to when it's used with ntp.
