NGINX - 反向代理，但一个子文件夹到静态本地目录

Question

我无法弄清楚将大多数流量代理到本地 Solr 安装但将一个路径/目录请求发送到静态 html 目录的基本语法。所有二级、三级等位置是否都需要通过正则表达式设置？还没有找到关于此问题的简单指南。

当前错误：/adv/index.html - 404 - 未找到 /adv/ - 403 禁止 /solr/ - 工作正常

这是我的配置：

user www-data;
worker_processes auto;
pid /run/nginx.pid;
#include /etc/nginx/modules-enabled/*.conf;

events {
        worker_connections 1024;
        multi_accept on;
}

http {
        sendfile on;
        tcp_nopush on;
        tcp_nodelay on;
        keepalive_timeout 65;
        types_hash_max_size 2048;
        index index.html;

        include /etc/nginx/mime.types;
        default_type application/octet-stream;
        server {
                listen 80;

                location / {
                    proxy_pass http://localhost:8983;
                }

                location /adv/ {
                        # also wasn't sure what permissions needed here
                        # recursively set adv folder and files within to 777
                        alias /var/www/adv;
                }
        }
}
