Test the Cluster of Redis Cluster on Windows to fill in the note, redisclusterFor the principle of redis cluster implementation, see the http://www.tuicool.com/articles/VvIZje cluster environment requires at least three nodes. We recommend that you use six nodes, namely three master nodes and three slave nodes. Create

LVS is a short name for Linux virtual server, the Linux web, is a free software project initiated by Dr. Zhangwensong and is now part of the Linux standard kernel. Prior to the Linux2.4 kernel, the LVS had to be recompiled to support the LVS function module, but since the Linux2.4 kernel, the various functions of LVS have been built-in, without any patching of the kernel, and the functions provided by LVS can be used directly. The goal of using LVS technology is to achieve a high-performance, hi

[Redis] 3. Redis cluster deployment and redis cluster deployment A Redis cluster is an assembly that provides data sharing among multiple Redis nodes.Redis clusters do not support the processing of multiple keys commands, because this requires moving data between different nodes, so as to achieve performance like Redis, unexpected errors may occur under high load

Fei Fei 2017-10-24 09:10 What is a cluster A computer cluster, called a "cluster", is a computer system that connects highly closely with a set of loosely integrated computer software and/or hardware to perform computational work. In a sense, they can be seen as a computer. A single computer in a clustered system is often called a node, usually connected over a l

This paper is based on Anand Rajaraman and Jeffrey David Ullman co-author, Wang bin translation of "Big data-Internet large-scale data mining and distributed processing" book.The Kmeans algorithm is the most commonly used clustering algorithm, the main idea is: in the case of a given k value and K initial class cluster center point, each point (i.e. data record) is divided into the class cluster that is rep
