Nginx configuration and usage

The biggest advantage of using Nginx is that if you want to use server load balancer, you can modify the configuration of the http node as follows: [html] # sets the http server and uses its reverse proxy function to provide load balancing support for http {# sets the mime type, which is determined by mime. the type file defines include/etc/nginx/mime. types; default_type application/octet-stream; # set the log format access_log/var/log/nginx/access. log; # omitting some of the preceding configuration nodes #.......... # Set the upstream mysvr {# The weigth parameter in the server list of server load balancer to indicate the weight. the higher the weight, the higher the probability of being allocated to the server 192.168.8.1x: 3128 weight = 5; # enable port 3128 of server 192.168.8.2x: 80 weight = 1; server 192.168.8.3x: 80 weight = 6;} upstream mysvr2 {# The weigth parameter indicates the weight, the higher the weight, the higher the probability of being allocated to the server. the higher the weight, the higher the server 192.168.8.x: 80 weight = 1; server 192.168.8.x: 80 weight = 6 ;} # The first virtual server {# listens to port 80 of 192.168.8.x listen 80; server_name 192.168.8.x; # server load balancer request location ~. * \.
