Build a Web cluster using HaproxyExperimental Introduction: Haproxy is a popular cluster scheduling tool, compared to similar cluster scheduling tools such as LVs and Nginx, LVS performance is the best, but the building is relatively complex, nginx upstream module support cluster function, However, the health function of the cluster node is not strong, the performance is not haproxy good, so this time we us

Haproxy Introduction:Haproxy provides high availability, load balancing, and proxies based on TCP (layer fourth) and HTTP (layer seventh) applications, supporting virtual hosts;Haproxy is especially useful for web sites that are particularly heavily loaded, and often require session-hold or seven-tier processing. Haproxy runs on today's hardware, fully supports t

In the MySQL world, Haproxy is often used as a software load balancer. Peter Boros explains how to use the Percona xtradb cluster (PXC) to set it up in a previous message. So it only sends the query to the applicable node. The same method can be used for general master-slave settings to read the load and spread across multiple nodes. However, with MySQL replication, another factor starts to work: replication latency. In this case, the mentioned Percon

High-availability cluster for HAproxy Based on Keepalived 1. Introduction to Keepalived Keepalived is used to detect the status of a web server. If a web server crashes or fails to work, Keepalived will detect it and remove the faulty web server from the system, when the web server is working normally, Keepalived automatically adds the web server to the server group. All these tasks are completed automatically without manual interference. All you need

PS: nginx/LVS/haproxy is currently the most widely used three load balancing software. I have implemented these software in multiple projects. I have referenced some materials and combined some of my experience in using it, to sum up. Generally, Server Load balancer uses different technologies at different stages as the website scale increases. Specific Application requirements have to be analyzed. For small and medium-sized web applications, such a

I. background The company recently used the exchange mail system to build a highly available mail system architecture. Front-End Server Load balancer uses Microsoft's NLB to achieve CAS load balancing. However, some problems have also been found in the solution implementation project. using NLB to generate a large number of broadcast reports in the network causes serious packet loss problems. Then we use haproxy to replace NLB to achieve CAS load ba
