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

Overview:Haproxy is a cluster scheduling tool that provides high availability, load balancing, and proxy software based on TCP (layer fourth) and HTTP (layer seventh) 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.

Haproxy is currently a popular cluster scheduling tool, similar cluster scheduling tool has many, such as LVS and Nginx, compared to the best performance of LVS, but the construction of relatively complex, Nginx upstream module support cluster function, but the cluster node health Check function is not strong, Performance is not hapr oxy good. The official website of Haproxy is http://
