ceph

Docker Registry 2.0, the backend supports Ceph storage for the music vision Cloud. And in the same way that Docker hub adds permissions and authentication mechanisms, only users with the appropriate permissions can push and pull on specific images. You can also set the image to be exposed, and any user that exposes the image can pull. COMPUTE Nodes: Physical machine, kubernetes node concept. Application: Defines a set of containers that provide t

frameworks and methods for interacting applications. Apache Mesos is one such project. The project is dedicated to providing high-level abstraction API interfaces for resource management and scheduling across cloud environments. Other such projects include Apache Aurora,twitter, which uses the project to provide service scheduling capabilities for Mesos. At a higher level, a cloud service management platform like MANAGEIQ provides some management methods for workload and policy control between

Memcached is a classic caching system, used in conjunction with lamp, LNMP popular architecture. Redis is a new Key-value key-valued NoSQL database for several years, and it can be persisted as a Key-value database in addition to being cached.(4) MySQL + Small File system (MongoDB, Ceph, etc.) Large s

Create several virtual machines, distributed in different physical host.4, choose three virtual machines, these virtual machine on different physical host server. Of these, two are used to install Oracle software, and the remaining virtual machine installs Openfiler as an iSCSI service. Ceph can be used directly for Oracle, but it is also cumbersome to configure.A

The monitoring tool OpenStack has its own ceilometer component provided, but the individual is not recommended to install because the monitoring program generates a lot of data and it is recommended to use other monitoring tools, such as Zabbix.3.

We can make multiple physical hard disk components through Ceph to a logical hard disk, so that all nodes are accessing the same address, or you can access the same Web project through the NFS shared file service with Linux itself. Whichever way you use it, we guarantee that:1) access to the same Web project2) The cube storage address is consistentBecause the same Web project requires the storage address of cu

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.
