abl*_*lmf 5 linux ntp vmware-workstation
编辑
我已经尝试了您的所有建议,但似乎 ntpd 只是拒绝同步到服务器。
[vivs@peter-centos ~]$ /usr/sbin/ntpq -np
remote refid st t when poll reach delay offset jitter
==============================================================
192.168.0.30 .LOCL. 1 u 11 64 3 0.984 232732. 20083.2

这个抖动“20083.2”是否表示时间是手动更改的?
我已经关闭了 vmware 的时间同步。
原始问题
这是ntp的状态
[root@peter-centos gw]# /usr/sbin/ntpq -pn
remote refid st t when poll reach delay offset jitter
=============================================
192.168.0.30 .LOCL. 1 u 153 1024 377 0.950 1905553 274023.
*127.127.1.0 .LOCL. 10 l 9 64 377 0.000 0.000 0.001

您可以看到它只与本地时钟“127.127.1.0”同步。
是不是因为偏移量太大了?
但是我手动设置date by date命令后,还是拒绝同步到192.168.0.30
这可能是ntp.conf

2021 年 4 月更新:至少从 2016 年开始,正确的答案是在 VM 中运行 NTP。下面的答案应该被弃用。
之前:
啊——现在清楚了:
我的机器安装在 vmware 工作站中。因此,从所有答案中,我想可能抖动变得如此大是因为 vmware 调整了时间。我会看看我是否正确。
不要在 VM 中运行 ntp。主机不保证 CPU 切片,因此 VM 的时钟不准确。如您所见,ntp 试图跟上看起来像是变化很大的外部时钟,但最终放弃了。
这个问题的一般答案是不运行 ntp,安装 VMware 工具并将 VM 的时钟锁定到主机的时钟。
具体答案取决于您运行的 Linux 版本。我在CentOS的一些注意事项(可能普遍适用于其他的RedHat家庭分布)在这里。
