haproxy architecture

Introduction: The difference between LVS and HaproxyLvs:1, strong anti-load capacity, is the work in the Network 4 layer on the distribution only, no flow generation;2, no flow, to ensure that the performance of the Equalizer IO will not receive the impact of large traffic;3, the application of a wide range, because LVS work in the 4 layer, so it can almost all applications to do load balancing4, the work is stable, because of its own resistance to load capacity is very strong, self has a comple

Today, a colleague came to me and said that their new website ulinux.img.bkjia.com.cn could not be accessed. The Code returned from the page was a test machine. 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
