【问题描述】：
我正在尝试使用 nginx 构建反向代理，以使我的项目中的所有 Is 都可以从单个地址访问。 对于单个服务，以下配置可以正常工作
/etc/nginx/sites-enabled/reverse-proxy.conf
server {
listen 80;
listen [::]:80;
location / {
resolver 127.0.0.1;
allow "x.x.x.x";
deny all;
proxy_pass http://consul:8500;
}
}
所以当我在浏览器中调用服务器的 ip x.x.x.x 时，我会看到 Consul UI 和显示 x.x.x.x/ui/dc1 的 URL。除此之外，我看到 UI 成功地请求了资产文件。
我的问题；是否有可能在同一台服务器上托管两个不同的服务，并且只在不同的位置引用它们？例如，如果我想包含 Vault UI，那么我会考虑做这样的事情：
server {
listen 80;
listen [::]:80;
location /consul {
resolver 127.0.0.1;
allow "x.x.x.x";
deny all;
proxy_pass http://consul:8500;
}
location /vault {
resolver 127.0.0.1;
allow "x.x.x.x";
deny all;
proxy_pass http://vault:8200;
}
}
但是我不确定这是否可以通过这种方式完成。我得到的最多的是打开 Consul UI，但没有找到所有其他子请求（即加载资产）。
更新
我认为我的问题是我错误地使用了location 和proxy_pass
观察第一个配置（正在运行）
server {
listen 80;
listen [::]:80;
location / {
resolver 127.0.0.1;
allow "x.x.x.x";
deny all;
proxy_pass http://consul:8500;
}
}
如果我查看 curl 命令curl localhost -L -vvvv

* TCP_NODELAY set

我已经可以看到 html 了。但是，如果我将 conf 文件更改为：
server {
listen 80;
listen [::]:80;
location /consul/ {
resolver 127.0.0.1;
allow "x.x.x.x";
deny all;
proxy_pass http://consul:8500;
}
}
然后尝试将其称为curl localhost/consul -L -vvvv，我得到以下信息：
* Trying 127.0.0.1:80...
* TCP_NODELAY set
* Connected to localhost (127.0.0.1) port 80 (#0)

我将不胜感激有关此问题的任何想法

nginX 可以为同一个 IP 地址上的多个域（或子域）提供服务。当然，不同的位置也可以代理到不同的后端。
