This is the advantage of nginx/haproxy + keepalived.2. If there are a large number of website applications, the implementation of LVS/DR +
LVS's working mechanism and scheduling algorithm have been recorded in my previous articles. See hereThe working mechanism of LVS is similar to iptabls. Some work in the user space (ipvsadmin) and some work in the kernel space. user space: used to define some load balancing objects and policies, for example, load the persistent connection to port 80 of the TCP protocol, or
