The Linux-HA (High-Availability Linux) project provides a high-availability (clustering) solution for Linux, FreeBSD, OpenBSD, Solaris and Mac OS X which promotes reliability, availability, and serviceability (RAS).

High-availability clusters (also known as HA clusters, failover clusters or Metroclusters Active/Active) are groups of computers that support server applications that can be reliably utilised with a minimum amount of down-time.

2018年12月19日 · In this article, we will demonstrate the basics of how to deploy, configure and maintain high availability/clustering in Ubuntu 16.04/18.04 and CentOS 7. We will demonstrate how to add Nginx HTTP service to the cluster.

2024年4月11日 · Linux, with its robustness and flexibility, serves as an ideal platform for deploying HA solutions. This article delves into the concept of Linux High Availability Clustering, exploring its mechanisms, technologies, and the vital role it plays in building resilient and fault-tolerant systems.

This document is a short description of how to get started with Linux-HA (heartbeat), especially from the software perspective. Getting Started with Linux-HA (heartbeat) Intro

The High Availability Add-On provides high availability clustering through its high availability service management component, Pacemaker. Red Hat provides a variety of documentation for planning, configuring, and maintaining a Red Hat high availability cluster.

2023年10月2日 · High availability is more than hitting an uptime service level agreement (SLA), or the expectations set between a service provider and client. It is about truly resilient, reliable, and well-functioning systems. Expand innovation and operational efficiency with Linux. Why is high availability important?

2000年9月8日 · High-Availability (HA) systems provide increased service availability through clustering techniques. HA clusters minimize availability interruptions by quickly switching services over from failed systems to working systems, providing the …

2020年3月18日 · But basic HA doesn't have to be complicated: in this series, you will learn about implementing basic, highly available services using Keepalived. I will take you through simple failover situations, as well as a more complex configuration used to respond to external events and trigger failovers.

2013年9月24日 · To enable high availability (HA), you need a minimum of two servers that are connected on a direct nonrouted local area network connection. Ideally, a second network connection separates the cluster traffic from normal network traffic.
