红帽全球峰会3.3. 配置 PTP-NTP 桥接
如果网络中有一个高度准确的精确时间协议(PTP)主时间服务器，但没有 PTP 支持的交换机或路由器，则计算机可能被专用于 PTP 客户端和 stratum-1 NTP 服务器。此类计算机需要有两个或多个网络接口，并且接近主时间服务器或与它直接连接。这样可保证高度准确的网络同步。
流程

配置
linuxptp软件包中的 ptp4l 和 phc2sys 程序，以使用一个接口，使用PTP来同步系统时钟。 配置
chronyd，以使用其他接口来提供系统时间：bindaddress 203.0.113.74 hwtimestamp enp1s0 local stratum 1
bindaddress 203.0.113.74 hwtimestamp enp1s0 local stratum 1Copy to Clipboard Copied! Toggle word wrap Toggle overflow 重启 chronyd 服务：
systemctl restart chronyd
# systemctl restart chronydCopy to Clipboard Copied! Toggle word wrap Toggle overflow
