#配置chrony服务#Chrony 是一个开源的自由软件，能保持系统时钟与时钟服务器（NTP）同步，在分布式#集群中，为了便于同一生命周期内不同节点服务的管理，需要各个节点的服务严格时钟同步，#以下配置中，以 client 节点作为时钟服务器，其他节点以 client 节点的时钟作为时钟标准调#整自己的时钟

#ceph节点和client配置chrony服务 yum -y install chrony

#client节点，配置为服务端vi /etc/chrony.conf#server 0.centos.pool.ntp.org iburst#server 1.centos.pool.ntp.org iburst#server 2.centos.pool.ntp.org iburst#server 3.centos.pool.ntp.org iburstserver ntp1.aliyun.comserver 210.72.145.44server 202.112.10.36allow 192.168.100.0/24local stratum 10

#其他三个节点，编辑 chrony.conf 配置文件，在所有默认的 server 前加“#”，并添加本地时钟服务器vi /etc/chrony.conf#server 0.centos.pool.ntp.org iburst#server 1.centos.pool.ntp.org iburst#server 2.centos.pool.ntp.org iburst#server 3.centos.pool.ntp.org iburstserver 192.168.100.100
