Recently, HAproxy + keepalived + mysql was used to test the high-availability Linux system cluster.HAProxy is a free proxy software that provides high availability, load balancing, and TCP (Layer 4) and HTTP (Layer 7) applications, with HAProxy, you can quickly and reliably provide Proxy solutions based on TCP and HTTP applications.Keepalived is mainly used for health checks between LoadBalance master and L

Build highly available reverse proxies with Haproxy and keepalivedBuilding high-availability reverse proxies with haproxy and keepalived in the case of a site with a large number of accesses, as the traffic increases, a single server is unable to process all the requests, which requires multiple servers to divert a large amount of requests, that is, load balancing. In the case of load balancing, these reque

Haproxy although with Ha, but it does is load balanced. Haproxy is working on the four floor, which means that it can represent a wider range of services than Nginx, with a higher performance than nginx. Compared to LVS, configurable and relatively good, the need for the machine is not more than LVS. So haproxy is good to use under certain demand. For example, us

First, IntroductionHaproxy provides high availability, load balancing, and proxies based on TCP and HTTP applications, supporting virtual hosting, which is a free, fast, and reliable solution. Haproxy is especially useful for Web sites that are heavily loaded, and often require session-hold or seven-tier processing. The haproxy runs on the current hardware and can support tens of thousands of concurrent con

What is Haproxy?Haproxy is a free and open source software written in C that provides high availability, load balancing, and TCP and HTTP-based application proxies that can run on most major Linux operating systems.This experiment uses three servers to build a Web cluster, haproxy as a dispatch server, two Nginx servers as node servers.Experimental environment

Compared with other Server Load balancer systems, the configuration and use of haproxy is relatively simple.The following is a self-installed and

Recently, a company's business has been growing fast, resulting in heavy pressure on front-end servers. in order to solve this problem as soon as possible, I submitted a request for purchasing servers to the company. soon the company approved the request and the servers were in place. how can we reasonably utilize the resources of newly purchased servers (originally a front-end server)? First, we thought that using nginx for load was a recent rapid development of a company's business, the pressu

1. Preface The previous section implemented a technical solution based on LVS (DR) + keepalived cluster. However, in terms of usage and maintenance, it was found that it is more difficult to maintain and implement than the haproxy + keepalived technical solution, the haproxy + keepalived cluster for Web applications is sufficient. Therefore, we recommend the haproxy
