This article mainly explains "what is a linux cluster". Interested friends may wish to take a look at it. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "what is a linux cluster"?

Now the larger system is basically the architecture of AP+DB, AP refers to the application, DB refers to the database side. Linux cluster means that multiple servers run the same AP application, which is equivalent to the work of system administrators.

Cluster system is mainly divided into high availability (High Availability) clusters, referred to as HA clusters, and high performance computing (High Perfermance Computing) clusters, referred to as HPC clusters.

Aiming at the demand of highly scalable and highly available network services, the Linux Virtual Server (Linux Virtual Service) project provides a load balancing scheduling solution based on IP layer and content request distribution, and implements these methods in the Linux kernel, forming a group of servers into a virtual server that implements scalable and highly available network services.

To put it simply, a cluster is a group of computers that provide users with a set of network resources as a whole. These individual computer systems are the node of the cluster.

For clustering, use MPICH and a set of ordinary Linux workstations. For simplicity and to highlight the fundamentals, you can build a minimal naked system and use it to run parallel programs in a clustered environment.

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

At this point, I believe you have a deeper understanding of "what is a linux cluster", might as well come to the actual operation of it! Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
