Method 1: simple, efficient, and easy to use
Ntpdate-u ntp. api. bz
Method 2: Time Server:
1) sudo yum install ntp
2) sudo nano/etc/ntp. conf
Comment a line
Restrict default ignore
Add a row
Restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap # server address
3) sudo nano/etc/ntp/step-tickers
Add a row (you can also rewrite it based on the original one)

In this way, the international standard time server will be automatically connected each time ntpd is started;
4) sudo systemctl restart ntpd
5) ss-an | grep 123
Make sure that the port is opened in udp mode.

6) sudo systemctl enable ntpdate. service (added to auto-start upon startup)
