我正在嘗試讓 nginx 連接到 FreeBSD 上的 uwsgi 套接字。我已將套接字設定為 666，但每當我在瀏覽器中發出請求時，我都可以在 nginx 日誌中看到以下內容：
2017/12/12 11:34:04 [crit] 1051#100213: *5 connect() to unix:/home/dashboard/dashboard/dashboard.sock failed (13: Permission denied) while connecting to upstream, client: <IP address>, server: <IP address>, request: "GET / HTTP/1.1", upstream: "uwsgi://unix:/home/dashboard/dashboard/dashboard.sock:", host: "<IP address>"
我的 nginx 流程：
root 1050 0.0 1.5 25496 7280 - Is 11:11 0:00.00 nginx: master process /usr/local/sbin/nginx
www 1051 0.0 1.6 25496 7756 - I 11:11 0:00.01 nginx: worker process (nginx)
我相信這是由於我的 uwsgi 進程（emeror、master 和工人）以 root 身份運行，而 nginx 以www.
我嘗試設定 uwsgi 的gid和uidtowww但 uwsgi 工作程序將失敗並出現以下錯誤：

另一方面，如果我讓它以 root 身份運行，nginx 將無法連接到 root 擁有的套接字。
在 FreeBSD 上讓 nginx 與 uwsgi 套接字對話的正確步驟是什麼？
