linux 下hermes开启gateway自启动报:Failed to connect to bus: No medium found

郑全

问题：
zq@hermes:~$ loginctl enable-linger $(whoami)

zq@hermes:~$ systemctl --user enable hermes-gateway
Failed to connect to bus: No medium found


原因：
     SSH 远程 session 缺少 D-Bus 环境变量


解决办法：

export XDG_RUNTIME_DIR=/run/user/1000
export DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/1000/bus

zq@hermes:~$ systemctl --user enable hermes-gateway
Created symlink /home/zq/.config/systemd/user/default.target.wants/hermes-gateway.service → /home/zq/.config/systemd/user/hermes-gateway.service.


验证：
  zq@hermes:~$ hermes gateway status
  Warning: OPENROUTER_API_KEY contained 7 non-ASCII characters (U+66FF ('替'), U+6362 ('换'), U+6210 ('成')) — stripped so the key can be sent as an HTTP header.
  This usually means the key was copy-pasted from a PDF, rich-text editor, or web page that substituted lookalike
  Unicode glyphs for ASCII letters. If authentication fails (e.g. "API key not valid"), re-copy the key from the
  provider's dashboard and run `hermes setup` (or edit the .env file in a plain-text editor).

以上在 ubuntu 24.4,rhel 10.1 上验证过。
