1. 思路
利用 systemd-timesyncd 服務實現
2. 實現
修改配置文件,重啟服務
nano /etc/systemd/timesyncd.conf
[Time]
NTP=10.1.89.1
重啟服務
systemctl restart systemd-timesyncd
3. 檢查
3.1 文件方式
/var/lib/systemd/timesync/clock
此文件的修改時間表示上次成功同步的時間戳。 如果無法同步，則至少表示 systemd 的 編譯時間。
/run/systemd/timesync/synchronized
每次同步成功時都會 touch 該文件，以幫助 systemd-time-wait-sync 及其他程序 檢測同步事件。
3.2 服務日志方式
systemctl status systemd-timesyncd
