CentOS安装时钟同步服务
使用chrony用于时间同步
代码语言：javascript复制yum install chrony -y
vim /etc/chrony.conf
cat /etc/chrony.conf | grep -v "^#" | grep -v "^$"
pool ntp.aliyun.com iburst
driftfile /var/lib/chrony/drift
makestep 1.0 3
rtcsync
allow 10.0.0.0/8
local stratum 10
keyfile /etc/chrony.keys
leapsectz right/UTC
logdir /var/log/chrony
systemctl restart chronyd
systemctl enable chronyd
复制代码客户端安装并配置
代码语言：javascript复制yum install chrony -y
vim /etc/chrony.conf
cat /etc/chrony.conf | grep -v "^#" | grep -v "^$"
pool 10.0.0.20 iburst
driftfile /var/lib/chrony/drift
makestep 1.0 3
rtcsync
keyfile /etc/chrony.keys
leapsectz right/UTC
logdir /var/log/chrony
systemctl restart chronyd ; systemctl enable chronyd
复制代码使用客户端进行验证
代码语言：javascript复制chronyc sources -v
.-- Source mode '^' = server, '=' = peer, '#' = local clock.
