1. 检查chrony是否安装

[root@localhost ~]# rpm -qa | grep chrony
chrony-4.3-1.el9.x86_64
[root@localhost ~]# ps -aux | grep chrony
chrony       898  0.0  0.1  84380  3420 ?        S    15:07   0:00 /usr/sbin/chronyd -F 2
root        3511  0.0  0.1 221796  2380 pts/1    S+   16:40   0:00 grep --color=auto chrony

2.编辑服务端配置文件

[root@localhost ~]# vim /etc/chrony.conf
#切换至第三行，更改配置内容为
   server ntp.aliyun.com iburst
 
#启用如下两行命令
# Allow NTP client access from local network.
allow 192.168.95.0/24
 
# Serve time even if not synchronized to a time source.
local stratum 10

3.重启服务,等待客户端连接

[root@localhost ~]# systemctl restart chronyd.service

二.客户端连接

1.检查chrony安装情况

[kehu@localhost ~]$ rpm -qa | grep chrony
chrony-4.3-1.el9.x86_64
[kehu@localhost ~]$ ps -aux | grep chrony
chrony       929  0.0  0.1  84380  3340 ?        S    08:11   0:00 /usr/sbin/chronyd -F 2
kehu        6560  0.0  0.1 221796  2328 pts/1    S+   08:14   0:00 grep --color=auto chrony
[kehu@localhost ~]$

2.配置客户端chrony

# Please consider joining the pool (https://www.pool.ntp.org/join.html).
pool 192.168.117.128 iburst

3.重启chrony，加载新配置以连接服务器

[root@kehu ~]# systemctl restart chronyd

4.测试

[root@client ~]# date -s 14:12:12
Wed Oct 29 02:12:12 PM EDT 2025
[root@client ~]# systemctl restart chronyd.service
[root@client ~]# date
