NOTE: For the following content, refer to Chapter 6 of "building a high-availability Linux Server" of fuqin liquor. It is relatively simple to set up a high-availability server Load balancer environment, mainly to understand the principle. This article describes the advantages and disadvantages of the three load balancers so that they can be selected as needed in actual production applications. Currently, there are F5 BIG-IP, LVS, nginx and haproxy, a
