Build a Web cluster using Haproxy
Haproxy provides high availability, load balancing, and proxies based on TCP and HTTP applications, supporting virtual hosting, which is a free, fast, and reliable solution. The haproxy runs on the current hardware and can support tens of thousands of concurrent connections. a

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 environmentHost | System | IP
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 Case Overview------------Preface: The landlord built several clusters before, such as Tomcat+nginx load Balancing cluster, LVS load Balancing cluster, Haproxy cluster and three kinds of clusters compared to the LVS performance is the best, but the building complex, we just did this experiment, Also deep experience, Nginx upstream module support cluster, but the cluster node fault check function is n

These days I compare nginx and Haproxy, and come to a surprising result.First, some background information is presented. For a long time, we bengler the Nginx as the main Web server for our project, just as we did under mongrel as a proxy for rails. Nginx is a very good small open source software, it occupies a small space, a reasonable configuration language, advanced features and fast. However, we quickly

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
