参考文章:

https://docs.nginx.com/nginx/admin-guide/load-balancer/http-load-balancer/

根据路径,进行一致性hash,具体的配置方法

upstream backend {

    hash $request_uri consistent;

    server backend1.example.com;

    server backend2.example.com;

}

需要注意的是:顺序不能错,否则会报错

nginx: [warn] load balancing method redefined in /etc/nginx/conf.d/upstream.conf:5
