How is the proxy_pass configured in nginx?

In nginx, you can use the proxy_pass directive to set the address and port of the proxy server. The syntax of the proxy_pass directive is as follows:

location /path {
    proxy_pass http://backend_server;
}

/path is the path being accessed, and http://backend_server is the address and port of the proxy server. For example, if you want to forward the request to port 8000 locally, you can set it like this:

location / {
    proxy_pass http://localhost:8000;
}

In this way, all requests to the root path will be forwarded to the local port 8000.
