Centos7 NTP时间无法同步 |
CentOS 7, 配置过ntpd与某个时间服务器同步后,偶然发现某一个节点的NTP synchronized一直是no: # timedatectl Local time: 二 2019-07-30 09:41:08 CST Universal time: 二 2019-07-30 01:41:08 UTC RTC time: 二 2019-07-30 01:08:13 Time zone: Asia/Shanghai (CST, +0800) NTP enabled: yes NTP synchronized: no RTC in local TZ: no DST active: n/a 停掉ntpd, 执行ntpd -gq重新调整时间后,再启动ntpd: # 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 Local time: 二 2019-07-30 09:44:28 CST Universal time: 二 2019-07-30 01:44:28 UTC RTC time: 二 2019-07-30 01:44:28 Time zone: Asia/Shanghai (CST, +0800) NTP enabled: yes NTP synchronized: yes RTC in local TZ: no DST active: n/a |
