Centos7配置rdate进行时间同步

一、服务端安装xinetd

[root@server01 ~]# yum install -y xinetd rdate

二、修改time-stream文件

disable = yes 改为 disable = no

[root@server01 ~]# vim /etc/xinetd.d/time-stream
service time
{
# This is for quick on or off of the service
        disable         = no

三、启动xinetd

[root@server01 ~]# systemctl start xinetd

四、设置开机自动启动

[root@server01 ~]# systemctl enable xinetd

五、客户端通过rdate访问该机器进行时间同步

[root@server03 ~]# rdate -s ip

[grid@server03 ~]$ date; ssh server01 date
Sun Jan 16 15:25:16 CST 2022
Sat Jan 15 15:25:18 CST 2022

[root@server03 ~]# rdate -s server01

[grid@server03 ~]$ date; ssh server01 date
Sat Jan 15 15:36:33 CST 2022
Sat Jan 15 15:36:34 CST 2022
