在初始部署 VMware Cloud Director 應用裝置後,可以變更 NTP 伺服器組態。
程序
- 以 root 身分直接登入或使用 SSH 用戶端登入 VMware Cloud Director 應用裝置主控台。
- 若要修改 NTP 伺服器,請編輯 /etc/systemd/timesyncd.conf 檔案。
/etc/systemd/timesyncd.conf 檔案的內容必須類似於以下內容。若要指定多個 NTP 伺服器,請使用空格分隔清單。

[Time] #FallbackNTP=time1.sample-time-server.com time2.sample-time-server.com time3.sample-time-server.com time4.sample-time-server.com NTP=time.sample-time-server.com
- 重新啟動 NTP 服務。
systemctl restart systemd-timesyncd.service -l
- 確認該服務正常執行。
timedatectl status
timedatectl 命令的範例輸出。Local time: Tue 2022-12-13 15:29:18 UTC Universal time: Tue 2022-12-13 15:29:18 UTC RTC time: Tue 2022-12-13 15:29:18 Time zone: Etc/UTC (UTC, +0000) Network time on: yes NTP synchronized: yes RTC in local TZ: no
- 將時間同步到 NTP 伺服器。
ntpdate time_server
- 對叢集中的每個應用裝置重複步驟 2 至 5。
