Recently, the company wanted to provide customers with a cluster solution. The project team adopted Apache and tomcat cluster configuration to achieve load balancing. I have never been familiar with Apache before, so I have some hands-on skills. I also searched for many clus
A vertical load is the load between different servers in the same machine. The biggest difference from a horizontal load (the load between servers with different IPs) is to modify the tomcat port number to avoid causing conflicts.Also pay attention to
use their own web site so that their web site is split up reasonably. * We provide a load-balanced web site, which means that multiple Tomcat workers are used simultaneously, and each tomcat worker has a separate host and assigns requests forwarded over the Web server between workers. Of course, these scenarios may not cover all the situations where multiple w

according to certain algorithms, balance the load of all servers in the cluster as much as possible. For external clients, they do not know which server in the cluster is accessed. multiple servers can be regarded as a "large" server logically. In this way, when the service capabilities of the cluster cannot meet the current needs, it is very convenient to add new servers to the cluster to meet the needs. It can be seen that the system has excellent
