1 、服务端
1.1 、检查服务是否存在
如果服务存在可以跳过1.2、1.3直接进行配置文件修改
systemctl status chronyd1.2、上传安装包
如果不存在需要上传安装包如果存在可以跳过此步骤。
上传后进行解压
# 解压到 /root目录下
[rootCentos package]# unzip chrony.zip -d /root# 解压后得到chrony目录包含rpm包和chrony.conf配置文件
[rootCentos chrony]# ll

1.3 、安装

备份原来配置文件
mv /etc/chrony.conf /etc/chrony.conf_bak
cp /root/chrony/chrony.conf /etc/修改配置文件

1.5、重启服务
systemctl start chronyd
systemctl status chronyd
netstat -anput |grep 1232、客户端配置
2.1、查看服务状态
systemctl status chronyd如果服务不存在参考客户端1.2、1.3步骤
