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 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 t

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 discovered that the load balancing feature o

feature is richer and more flexible, and makes the entire network smarter. As shown, the connections on both sides of the seven-tier load balancer (client-side and server-side) are independent.3. In short, four-tier load balancing is based on the ip+ port. Seven-tier load balancing is achieved through application-level resources.second, common load balancing software comparisonFeatures of LVS:1. Strong anti-load capability. Strong resistance to load, high performance, up to 60% of F5 hardware,
