1. Like Apache, they are both HTTP server software and adopt Modular Design for function implementation. They all support common language interfaces. At the same time, they also support forward and reverse proxies, virtual hosts, and URL rewriting,CompressionTransmission, SSL encrypted transmission, and so on. However, in terms of execution efficiency, nginx processes faster and consumes less memory resources. In addition, nginx also supports fcgi, wh

Ngigx + Tomcat configure static/dynamic separation, Server Load balancer, and ngigxtomcat Since the company used Ngnix, I felt a little curious about Nginx, So I studied it. My version used in windows is nginx-1.8.1: 1. Start Ngnix Double-click nginx-1.8.1. nginx.exe in the folder. If two nginx processes exist in the task manager, the startup is successful! 2. Common Ngnix commands Forced nginx-s stop Shutd

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.
