![无法启动 NTP](https://linux22.com/image/74110/%E6%97%A0%E6%B3%95%E5%90%AF%E5%8A%A8%20NTP%20.png)
上周它工作正常,但现在,我的 virtualbox 内的虚拟机不同步了 5 分钟
$ systemctl status systemd-timesyncd

$ cat /etc/systemd/timesyncd.conf
[Time]
NTP=0.asia.pool.ntp.org,1.asia.pool.ntp.org,2.asia.pool.ntp.org,3.asia.pool.ntp.org
FallbackNTP=0.arch.pool.ntp.org 1.arch.pool.ntp.org 2.arch.pool.ntp.org 3.arch.pool.ntp.org
是什么原因造成的NTP synchronized: no
?
我正在使用 64 位 ArchLinux 并且https://wiki.archlinux.org/index.php/Systemd-timesyncd
编辑啊现在可以了
$ sudo systemctl daemon-reload
$ systemctl restart ntpd
$ systemctl restart systemd-timesyncd
$ systemctl restart ntpd

答案1
您正在尝试在虚拟机上运行完整的 ntp 服务器。 ntp 和虚拟机不能很好地协同工作,因为模拟时钟违反了 ntp 所做的假设。而是在主机上运行 ntp,在虚拟机上运行 sntp 以同步到主机。这不太准确,但不存在在虚拟机上运行 ntp 的同步问题。
