Build an NTP environment in CentOS
Recently, an Openstack and Ceph cluster were built. Because multiple nodes exist in the cluster and time synchronization is required between nodes, NTP is required. In addition, in some cases, the network environment is closed, therefore, you need to build an NTP server.

Establishment and use of NTP servers
In high-availability clusters, the time requirements for each node are strict. Therefore, we need to configure an NTP server to implement the time synchronization of highly available clusters. Point other node time to this
Step by step on the HP-UX to configure NTP-Linux Enterprise Application-Linux server application information, the following is detailed reading. To achieve time synchronization on the HP-UX, you need to set the time server and client, the relevant process is xntpd.
The specific configuration files are as follows:
