CentOS8系统同步时间

一、安装chrony

 

安装chrony
yum install -y chrony

启动 chrony
systemctl start chronyd

设为系统自动启动
systemctl enable chronyd

 

二、编辑配置etc/chrony.conf

 

1 [root@zabbix ~]# cat /etc/chrony.conf
2 # Use public servers from the pool.ntp.org project.
3 # Please consider joining the pool (http://www.pool.ntp.org/join.html).
4 #pool 2.centos.pool.ntp.org iburst
5 server ntp.aliyun.com iburst
6 server cn.ntp.org.cn iburst

 三、重新加载配置并测试

 1 [root@zabbix ~]# systemctl restart chronyd.service
 2 [root@zabbix ~]# chronyc sources -v
