, Twitter and Tuenti, and the Amazon Web Services system all use Haproxy. Haproxy is a popular cluster scheduling tool at present, 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

Introduction and orientation of Haproxy Haproxy provides high availability , load Balancing , and proxies based on TCP and HTTP applications to support virtual hosts , a free, fast, and reliable solution. According to official data, its maximum limit supports 10G concurrency. Haproxy is especially useful for Web sites that are heavily loaded, which typically r

Software load balancing is generally implemented in two ways: software load implementation based on the operating system and software load implementation based on third-party applications. LVS is a kind of soft load based on the Linux operating system. HAProxy is an open-source software load based on the third application. Nginx can also be used, but nginx only w

haproxy+keepalived Build WEB Cluster We have learned two Web cluster software nginx and LVS, they have their own characteristics, this chapter will introduce another cluster software haproxy, we will be on its scheduling algorithm, cluster environment, as well as the configuration of the cluster to explain. Haporxy is currently a more popular scheduling tool, the

balancer, and seven-layer negative Load balancing can be handled according to the different Web pages of the client accessing the domain name. Common seven-tier load balancers have Haproxy, Nginx, and so on. Haproxy supports two main proxy modes: TCP is the 4 layer (mostly for mail servers, internal protocol communication servers, etc.). 　　In 4-tier mode,

B domain name into the English site, which is almost impossible to achieve in the four-tier load balancer, And seven-tier load balancing can be based on the client access to different domain names to select the corresponding Web page for load balancing processing. Common seven-layer load balancer has haproxy, nginx and so on.Here is still a common example of TCP applications, because the load balancer to o

Build a Web cluster using Haproxy Case Overview: Haproxy is currently a popular cluster scheduling tool. In comparison, LVS performance is the best, but the construction of complex, Nginx upstream module support cluster function, but the cluster node health Check function is not strong, performance is not haproxy
