The above is 1 Some basic configuration , use Nginx The biggest benefit is load balancing
If you want to use load balancing , You can modify the configuration http The nodes are as follows:
# set http Server, which provides load balancing support with its reverse proxy function
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
