linux主机安装配置chrony时间同步器

1.安装chrony,自行百度，或者下载安装包
2.配置阿里云同步器
 server ntp.aliyun.com iburst
 stratumweight 0
 driftfile /var/lib/chrony/drift
 rtcsync
 makestep 10 3
 bindcmdaddress 127.0.0.1
 bindcmdaddress ::1
 keyfile /etc/chrony.keys
 commandkey 1
 generatecommandkey
 logchange 0.5
 logdir /var/log/chrony
 
配置完成重启chrony客户端服务
systemctl restart chronyd

查看时钟源
