This article is about how to configure clock synchronization in Linux. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Installation

Timesync is usually pre-installed. If not, you can install it manually using the following command.

Sudo apt install systemd-timesyncd it conflicts with ntp, and only one can be installed.

Configuration

Modify / etc/systemd/timesyncd.conf to make NTP a NTP server accessible to Huawei's Inner Green Zone.

[Time] NTP=ntp7.aliyun.comNTP=ntp6.aliyun.com

After the modification is completed, this configuration will not take effect until restart is required.

Sudo systemctl restart systemd-timesyncd.service

If the above systemd-timesyncd.service does not exist for any reason, it can be repaired with the following command:

Sudo dpkg-reconfigure systemd-timesyncd

View the effect

Date is generally used to view the date and time. Use timedatectl to see more information about clock synchronization.

$timedatectl status Local time: two 2020-09-22 20:06:05 CST Universal time: two 2020-09-22 12:06:05 UTC RTC time: two 2020-09-22 12:06:05 Time zone: Asia/Shanghai (CST, + 0800) System clock synchronized: yes NTP service: active RTC in local TZ: no

List of domestic NTP servers

Here are some NTP lists of Aliyun, which can be used preferably through ping.

Ntp1.aliyun.comntp2.aliyun.comntp3.aliyun.comntp4.aliyun.comntp5.aliyun.comntp6.aliyun.comntp7.aliyun.com
