nginx多服务器下载文件配置

　　1.场景
　　两台服务器在同一个局域网内
　　A服务器公网80端口可以访问
　　B服务器是内部文件服务器，外网不能直接访问
　　需求：A服务器配置域名，转向到B服务器可以直接下载文件 2.nginx配置
　　A服务器和B服务器都安装nginx
　　A服务器Nginx配置    upstream upload_bjsh_net {     server 172.16.60.19:8888; }  server {   listen 80;   server_name upload.bjsh.net;   location / {     				proxy_buffer_size  128k; 						proxy_buffers   32 32k; 						proxy_busy_buffers_size 128k;             proxy_pass http://upload_bjsh_net;             proxy_set_header Host $http_host;             proxy_set_header X-Real-IP $remote_addr;             proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;  						proxy_connect_timeout 600s; 						proxy_send_timeout 600s; 						proxy_read_timeout 600s;     } }
　　B服务器nginx配置     server {   listen 8888;   server_name localhost;   charset utf-8;   root /home/upload;   index  index.html index.htm;   autoindex on; }
　　两台服务器nginx都启动
　　通过域名http://upload.bjsh.net/rfUpload/2.txt 就可以从B服务器下载文件 3.注意事项
　　配置完成后，有的时候会报如下错误，这是权限问题     2023/01/08 14:48:54 [crit] 12165#12165: *1948542 open() ＂/usr/local/nginx/proxy_temp/5/09/0000011095＂ failed (13: Permission denied) while reading upstream, client: 20.2.7.105,    server: upload.bjsh.net, request: ＂GET /rfUpload HTTP/1.1＂,       upstream: ＂http://172.16.60.19:8888/rfUpload/＂,          host: ＂＂, referrer: ＂http://upload.bjsh.net/rfUpload/＂
　　解决办法 chown -R nobody:nobody /usr/local/nginx/proxy_temp
