autossh 在终端运行良好，但机器人导致 systemctl 的权限被拒绝

我正在尝试在树莓派上集成 autossh。

如果我单独启动命令

autossh -o "ServerAliveInterval 10" -o "ServerAliveCountMax 3" -N -R 22002:localhost:22 user@myserver

一切正常，但从 systemctl 启动相同的命令

[Unit]
Description=AutoSSH tunnel service Remote port 22002 to local 22
After=network.target
[Service]
Environment="AUTOSSH_GATETIME=0"
ExecStart=/usr/bin/autossh -o "ServerAliveInterval 10" -o "ServerAliveCountMax 3" -N -R 22002:localhost:22 [email protected]
[Install]
WantedBy=multi-user.target

返回

Jun 25 13:43:22 pi autossh[995]: ssh exited with error status 255; restarting ssh

我可以从我的 pi 无需密码即可 ssh 我的服务器。

/var/log/auth.log 中的日志给了我这个

我应该检查或者做些什么吗？

谢谢，

好的，找到了，我只需要添加用户，因为密钥是针对用户的，并且 systemd 以 root 身份运行

[Service]
User=myuser
