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://

cluster configuration, is a real server, a backend corresponding to one or more entity servers 5. Combination of Listen fronted and backend First, install the Haproxy 1.

forwarding. This allows you to perform protocol validation instead of blindly forwarding. For example, allow SSL but deny SSH. L More load balancing algorithms: Now, Dynamic weighted rotation (dynamical Round Robin), weighted source address hash (weighted source hash), weighted URL hash and weighted parameter hash (weighted Parameter hash) has been implemented. Other algorithms such as weighted measured Response time will also be implemented soon. Installation and Configuration The
