我试图通过从没有 tty 的用户（我的 apache 服务器运行的用户）调用 ssh（使用密钥身份验证）来运行单个命令，并不断得到以下结果：
OpenSSH_5.9p1, OpenSSL 1.0.0g 18 Jan 2012

-t 标志在调用 ssh 时设置。密钥没有密码，这应该可以抑制对任何输入的需求，但显然没有。如何防止 ssh 尝试打开 /dev/tty？
编辑：代码标签不起作用？
Edit2：完整的 ssh 命令：
ssh -i nonpublic/id_rsa -l username -p 54367 -t -v username@localhost /home/username/minecraftserver/Scripts/start 2>&1
我已经用“用户名”替换了我的用户名。
Edit3：我尝试使用与 root 相同的密钥进行 ssh-ing 并得到以下结果：

即使它不需要密码，它也会提示我输入密码。此外，我可以在 Windows 机器上使用 PuTTY 使用 ssh 的密钥，这很好，它不会提示我输入密码。
Edit4：我将服务器添加到了 apache 用户 known_hosts，现在我得到了这个：

此外，这是 known_hosts 的内容：
[localhost]:54367 ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBILr7jLp5CeYfyrCroaDjkaWgDHXRrQD+G8Fz/CQOY1PcluUFTkrN447bXmC6R27LOClE+RPaveYb4MOlObpGGE=
为什么说是ecdsa？这是一个 rsa 密钥。
编辑5：解决了。问题是密钥对是由 PuTTY 生成的，它以与 OpenSSH 不兼容的格式写入私钥。cjc 在评论中提供的解决方案。

问题实际上似乎并不在于它正在尝试读取密码——这只是一个警告。相反，它试图进行主机密钥验证但失败了。如果您真的希望它从不询问主机密钥，请考虑将以下选项添加到 ssh 命令行：
-o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -o GlobalKnownHostsFile=/dev/null
请注意，可能存在安全隐患，因此请务必阅读ssh_config手册页中的这些选项。
编辑：鉴于您更新的错误消息，您的身份文件似乎已损坏（或者如 cjc 指出的那样，它可能格式错误）。尝试使用 ssh-keygen 手动创建一个新的，并将其添加到服务器的 authorized_keys。
