Description Operating system: CentOS 5.X 64-bit Web server: 192.168.21.127, 192.168.21.128 Sites: Bbs.111cn.net and Sns.111cn.net deployed on two Web servers To achieve the purpose: Add two servers (main main mode) to achieve Web server load balancing through haproxy+keep
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 that support Virtual Host , it 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. Experiment (I.)Experimental purpose: Using
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

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
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
