同步没成功:
# timedatectl status Local time: Tue 2022-04-26 21:46:24 CST Universal time: Tue 2022-04-26 13:46:24 UTC RTC time: Tue 2022-04-26 13:45:13 Time zone: Asia/Shanghai (CST, +0800) NTP enabled: yes NTP synchronized: no RTC in local TZ: no DST active: n/a
解决:
# systemctl stop ntpd # ntpd -gq ntpd: time slew +0.000041s # systemctl start ntpd 等待一会儿后,NTP synchronized恢复成yes: # timedatectl
