Lorsque j'utilisais les paramètres par défaut du serveur, j'ai remarqué que la synchronisation de l'heure était désynchronisée, la procédure de configuration de NTP est donc indiquée ci-dessous.
$ cat /etc/redhat-release
CentOS Linux release 8.1.1911 (Core)
$ cp -pi /etc/chrony.conf{,.org}
$ vi /etc/chrony.conf
$ diff chrony.conf chrony.conf.org
3,5c3
< #pool 2.centos.pool.ntp.org iburst
< pool ntp.nict.jp iburst
< pool ntp.jst.mfeed.ad.jp iburst
---
> pool 2.centos.pool.ntp.org iburst
$ systemctl restart chronyd.service
$ systemctl enable chronyd.service
Created symlink /etc/systemd/system/multi-user.target.wants/chronyd.service → /usr/lib/systemd/system/chronyd.service.

Étant donné que nslookup est également répondu par le serveur DNS de cache, et non par le serveur faisant autorité, l'emplacement ne peut pas être spécifié ...
