Rocky Linux 8通过chrony模块设置时间同步

内网有一台Rocky Linux8.4的服务器,想设置时间同步,发现ntpdate不能用,经查,可使用chrony模块来实现。

查看系统版本

[root@SVN ~]# cat /etc/redhat-release
Rocky Linux release 8.4 (Green Obsidian)

修改chrony配置文件

vim /etc/chrony.conf
  • 因为我这边有内网NTP服务器192.168.1.120,所我就改成下面这样
[root@SVN ~]# cat /etc/chrony.conf | grep -Ev '^$|#'
server 192.168.1.120 iburst
server ntp.aliyun.com iburst
driftfile /var/lib/chrony/drift
makestep 1.0 3
rtcsync
keyfile /etc/chrony.keys
leapsectz right/UTC
logdir /var/log/chrony

重启服务

systemctl restart chronyd.service

同步

[root@SVN ~]# chronyc sources -v
210 Number of sources = 1

  .-- Source mode  '^' = server, '=' = peer, '#' = local clock.
 / .- Source state '*' = current synced, '+' = combined , '-' = not combined,
| /   '?' = unreachable, 'x' = time may be in error, '~' = time too variable.
