Nginx Load Balancer Configuration Example

Example of an nginx load balancer configuration. The configuration examples for load balancing are as follows:

Http{   upstream server {     server 192.168.10.100:80  weight=3 max_fails=3 fail_timeout=25s;     server  192.168.10.101:80 weight=1 max_fails=3 fail_timeout=25s;     server  192.168.10.102:80 weight=4 max_fails=3 fail_timeout=25s;      server 192.168.10.103:80 weight=2 max_fails=3 fail_timeout=25s;      }   server {   listen 80;   server_name   ;    index index.htm index.html;   root /d21414/web/ Www;location / {     proxy_pass      proxy_ next_upstream http_500 http_502 http_503 error timeout invalid_headerl      include /etc/nginx/proxy.conf;      }   }} 

Note:

1. Configure load Balancing using the Nginx keyword to identify the upstream. A Load Balancer server server (name is optional) is specified through upstream.

2. Use the Proxy_next_upstream parameter to define the fault error. When a node returns an error such as 500. Upstream will be forwarded to weight (the higher the weight value, the higher the access probability assigned).
