.::: How to Install and Configuration PCS, COROSYNC, and Pacemaker for HA(High Availability) On Linux, Centos, Rhel :::.

Corosync is an open source cluster engine used to implement high availability within applications. Commonly referred to as a messaging layer, Corosync provides a cluster membership and closed communication model for creating replicated state machines, on top of which cluster resource managers like Pacemaker can run. Corosync can be seen as the underlying system that connects the cluster nodes together, while Pacemaker monitors the cluster and takes action in the event of a failure.

This tutorial will demonstrate how to use Corosync and Pacemaker to create a high availability (HA) infrastructure on DigitalOcean with CentOS 7 servers and Floating IPs. To facilitate the process of setting up and managing the cluster nodes, we are going to use PCS, a command line interface that interacts with both Corosync and Pacemaker.A. Pre Activity

.::: Setting NFS Server & NFS Client (FreeNAS) on Centos7 to Connect Network Share :::.

Network File System (NFS) is a distributed file system protocol originally developed by Sun Microsystems in 1984, allowing a user on a client computer to access files over a computer network much like local storage is accessed. NFS, like many other protocols, builds on the Open Network Computing Remote Procedure Call (ONC RPC) system. The NFS is an open standard defined in Request for Comments (RFC), allowing anyone to implement the protocol.
