What is a Linux cluster

The trunking communication system is a computer system,

It is connected by a set of loosely integrated computer software and/or hardware to complete the calculation work with high close cooperation. Simply put, a cluster is a group of computers that provide users with a set of network resources as a whole. These individual computer systems are nodes of a cluster. In an ideal cluster, users will not be aware of the nodes at the bottom of the cluster system. In their view, a cluster is a system, not multiple computer systems. And the administrator of the cluster system can add and delete nodes of the cluster system at will.

Cluster is not a brand-new concept. As early as 1970s, computer manufacturers and research institutions researched and developed the cluster system. These systems are not widely known because they are mainly used in scientific engineering calculations. It was not until the appearance of Linux cluster that the concept of cluster was widely spread. Cluster system is mainly divided into High availability (high

Availability) cluster, called high availability cluster, and high performance computing cluster, called high performance computing cluster.

Before the emergence of Linux, the main operating systems used by cluster systems were VMS, UNIX and WindowsNT. By the end of 1990s, the linux operating system was becoming more and more mature and its robustness was increasing. It provided GNU software and standardized PVM and MPI message mechanisms. The most important thing is that Linux provides support for high-performance networks on ordinary PCs, which greatly promotes the popularization and development of cluster systems based on Linux.
