The above are some basic configurations. The biggest benefit of using Nginx is load balancing

If you want to use load balancing, you can modify the configuration of the http node as follows:

# set http The server, with its reverse proxy function to provide load balancing support 
http {
# set mime type , Type by mime.type File defines 
include /etc/nginx/mime.types;
default_type application/octet-stream;
# Set log format 
access_log /var/log/nginx/access.log;
# Omit the above 1 Some configuration nodes 
# . 
# Set the list of load balancing servers 
upstream mysvr {
#weigth The parameter represents the weight, and the higher the weight, the more likely it is to be assigned 
server 192.168.8.1x:3128 weight=5;# This machine Squid open 3128 port 
server 192.168.8.2x:80 weight=1;
server 192.168.8.3x:80 weight=6;
}
upstream mysvr2 {
#weigth The parameter represents the weight, and the higher the weight, the more likely it is to be assigned 
server 192.168.8.x:80 weight=1;
server 192.168.8.x:80 weight=6;
}
# The first 1 2 virtual servers 
server {
# To listen to 192.168.8.x the 80 port 
listen 80;
server_name 192.168.8.x;
# right aspx Suffix the load balancing request 
location ~ .*\.aspx$ {
root /root; # Defines the default site root location for the server 
index index.php index.html index.htm; # Defines the name of the home page index file
