nginx load balancer setup

configuration file is divided into six main areas:Main (Global Settings), events (nginx working mode), HTTP (HTTP settings),Sever (Host settings), location (URL match), Upstream (Load balancer server settings). Main module Below a main area, he is a global setting: User nobody nobody; Worker_processes 2; Error_log/usr/local/var/log/

The following uses the reverse proxy function of Nginx to configure an Nginx load balancing server. The backend has three service nodes for providing Web Services, and load balancing of the three nodes is achieved through Nginx scheduling./Etc/

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,
