如何配置NTP时间客户端

要求：

配置你的系统，使其成为classroom.example.com的NTP客户端。

首先我们需要编辑/etc/chrony.conf文件

[root@bunian ~]# vim /etc/chrony.conf
# Use public servers from the pool.ntp.org project.
# Please consider joining the pool (http://www.pool.ntp.org/join.html).

# Ignore stratum in source selection.
server classroom.exmaple.com iburst  #这一行是我们要新添加的
stratumweight 0

配置完成，我们要重启一下服务

[root@bunian ~]# systemctl restart chronyd.service  #重启服务
[root@bunian ~]# chronyc sources  #进行同步
210 Number of sources = 1
MS Name/IP address         Stratum Poll Reach LastRx Last sample
