1. 参考配置

server {
 listen 80;
 server_name example.com;
 location / {
   proxy_set_header Host $http_host;
   proxy_pass http://localhost:9000;
 }
}

2. 添加存储处理

proxy_cache_path /path/to/cache levels=1:2 keys_zone=my_cache:10m max_size=10g inactive=60m
use_temp_path=off;
server {
    # ...
    location / {
        proxy_cache      my_cache;
        proxy_set_header Host $http_host;
        proxy_pass       http://localhost:9000;
    }
}

3. loadbalance 配置

 upstream minio {
       server 127.0.0.1:9001 weight=20 max_fails=2 fail_timeout=30s;
       server 127.0.0.1:9002 weight=10 max_fails=2 fail_timeout=30s;
       server 127.0.0.1:9003 weight=10 max_fails=2 fail_timeout=30s;
       server 127.0.0.1:9004 weight=10 max_fails=2 fail_timeout=30s;
    }
location / {
           # proxy_set_header X-Forwarded-For $remote_addr;
            proxy_set_header Host $http_host;
                client_body_buffer_size 10M;
                client_max_body_size 10G;
                proxy_buffers 1024 4k;
                proxy_read_timeout 300;
                proxy_next_upstream error timeout http_404;
                proxy_pass http://minio;
        }

可以拷贝配置

upstream minio_server {
    #以下4种均衡策略选一个
      # 1、默认轮询负载均衡least_conn;  
    # 2、最少连接负载均衡ip_hash;  
    # 3、会话持久化负载均衡
      # 4、带权重的负载均衡 
    server 192.168.8.110:9000 weight=3;
    server 192.168.8.110:9000;
    server 192.168.8.111:9000;
    server 192.168.8.112:9000;
    server 192.168.8.113:9000;
    }

server {
    listen 80;
    server_name example.com;
    #注意所有类型的location仅仅检验请求行(HTTP中的request line)中的URL部分，不带参数。这是因为请求字符串中的参数可以以多种方式给出
    location / {
        proxy_set_header Host $http_host;
        proxy_pass http://minio_server;
    }
}
