The configuration of HAProxy is divided into five parts. Of course, these components are not mandatory and can be selected as needed. Global: The parameter is process-level, usually related to the Operating System (OS. These parameters are generally set only once. If the configuration is correct, you do not need to modify defaults again: to configure the default parameter, which HAProxy Configuration The

The current development trend of the website for the use of network load balancing is as the scale of the website increases according to different stages to use different technologies:One is through hardware. Common Hardware includes expensive NetScaler, F5, radware, array, and other commercial load balancers, it has the advantage of a professional maintenance team to maintain these services. The disadvantage is that the cost is too large. Therefore, it is not required for small network services

Recently, the company had a project where users worried that a single machine could not afford the most users, and they required to use the application cluster. We designed the application cluster architecture based on the application situation.

Description: The following references the contents of the sixth chapter of "Building a highly available Linux server" Fuqin.It is relatively simple to build a high-availability environment for load balancing, mainly to understand the principles. This article describes the pros and cons of three load balancers so that they can be used in real-world production applications by demand.At present, the online environment in the application of more load balancer hardware has F5 big-IP, software has Lvs

My first response was a DNS resolution problem and dig was normal, no request for the header ulinux.img.bkjia.com.cn is sent when you log on to the backend web packet capture service. I caught a lot of results on the testing machine that my colleagues said. At this time, the haproxy rule shou
