This article mainly introduces Linux how to achieve clock synchronization, the article is very detailed, has a certain reference value, interested friends must read it!

Due to hardware reasons, the root standard time of the machine does not match more or less, and the error of a month ranges from a few seconds to a few minutes. For the server, the time is not right, there will be a lot of trouble. For example, when paying, the order cannot be placed, the game cannot log in, and so on. It doesn't matter if you use your own PC, just change it manually.

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 of them 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:

View the effect of sudo dpkg-reconfigure systemd-timesyncd

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.
