pve服务器内网同步时钟

1. 思路

利用 systemd-timesyncd 服务实现

2. 实现

修改配置文件,重启服务

nano  /etc/systemd/timesyncd.conf

[Time]
NTP=10.1.89.1

重启服务
systemctl restart systemd-timesyncd

3. 检查

3.1 文件方式

/var/lib/systemd/timesync/clock
此文件的修改时间表示上次成功同步的时间戳。 如果无法同步，则至少表示 systemd 的 编译时间。

/run/systemd/timesync/synchronized
每次同步成功时都会 touch 该文件，以帮助 systemd-time-wait-sync 及其他程序 检测同步事件。

3.2 服务日志方式

systemctl status systemd-timesyncd
>>
