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://

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

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 works on Layer 7 networks. Reference Software for details Server load balancerGenerally, tw

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 obtain the content of the message, so can only

LB load Balancing clusters are divided into two categories: LVS (four floors) and Nginx or haproxy (seven layers). LVS is ip-based, and Nginx and Haproxy are based on applications. The client accesses the Web site by accessing the Distributor's IP. The distributor forwards the request to the corresponding machine on the back-end, depending on the type of request. load Balancing cluster with static and dynam

A sticky component, usually applied to a navigation bar or toolbar, that uses elements such as navigation bars or toolbars at the top or bottom of a page when scrolling in an area, making it easy for users to quickly perform the actions provided by such elements. This paper introduces the realization of this kind of component, and provides a concrete implementation that supports fixing the sticky element at

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, Haproxy
