nginx负载均衡策略

轮询：将客户端发起的请求，平均分配给每一台服务器
权重：将客户的的请求，根据服务器的权重值不同，分配不同的数量
ip_hash：基于发起请求的客户端的ip地址不同，他始终会将请求发送到指定的服务器上，客户端ip地址不变，就会一直发送到一个服务器上。

轮询

upstream my_server{server IP:8080;server IP:8081;}server {listen80;listen[::]:80;server_namelocalhost;location / {proxy_pass http://my_server/;}}

权重【nginx web负载均衡配置】

upstream my_server{server IP:8080 weight=10;server IP:8081 weight=2;}server {listen80;listen[::]:80;server_namelocalhost;location / {proxy_pass http://my_server/;}}

ip_hash

upstream my_server{ip_hash;server IP:8080 weight=10;server IP:8081 weight=2;}server {listen80;listen[::]:80;server_namelocalhost;location / {proxy_pass http://my_server/;}}
