1. Polling (default)
Each request is assigned to a different back-end server in chronological order, and can be automatically rejected if the backend server is down.

## The default server#upstream192.168.93.128{        server192.168.1.8:80 weight=2;        server192.168.93.128:8080 weight=1;}server {    listen80;    server_name192.168.93.128;    location / {        #设置主机头和客户端真实地址，以便服务器获取客户端真实IPproxy_set_header$host;        proxy_set_header$remote_addr;        proxy_set_header$proxy_add_x_forwarded_for;        #禁用缓存proxy_bufferingoff;        #反向代理的地址proxy_passhttp://192.168.93.128;    }}

2, Ip_hash

Each request is allocated according to the hash result of the access IP, so that each visitor has fixed access to a back-end server that can resolve the issue.

3. Fair (third party)

The response time of the back-end server is allocated to the request, and the response time is short of priority allocation.

4. Url_hash (third Party)

Allocate the request by the hash result of the access URL so that the same URL is directed to the same back-end server, which is more efficient when the backend server is cached

The above describes the Nginx upstream load balancing, including the stream,nginx aspects of the content, I hope that the PHP tutorial interested in a friend helpful.
