服务的名称 : chronyd
在服务端:
vim /etc/chrony.conf
删除以下代码的注释
22 allow 172.25.36.0/24 #允许哪些客户端来同步本机的时间
29 local stratum 10 #本机不同步任何主机的时间，本机作为时间源
systemctl restart chronyd.service
timedatectl set-timezone Asia/Shanghai #更改当前时区
在客户端:
vim /etc/chrony.conf
3 server 172.25.35.86 #本机同步172.25.35.86主机的时间
timedatectl set-timezone Asia/Shanghai #同步当前时区
/etc/chrony.conf修改好后如下图
