bash腳本中的SSH仍然會提示輸入密碼，而命令行中的ssh使用密鑰進行身份驗證時

Question

我通過在每個站點上生成公共密鑰並將它們復制到另一個站點來配置兩個站點之間的SSH連接。 現在，我可以不用密碼從一個工作站連接到另一個工作站，但是如果我想編寫一個bash腳本與ssh連接，它仍然會要求輸入密碼。 我應該怎么做才能在運行腳本后不要求輸入密碼？

編輯：添加腳本。 我在station1上，我想連接到station2（主機）。

#!/bin/bash
ssh host

Edit2： ssh -v輸出

Edit3：station2名稱為主機

Answer 1

您的腳本在root帳戶下運行：

debug1: Reading configuration data /root/.ssh/config

因此，它將不使用user帳戶的密鑰。

---

我們不知道您如何運行腳本。

但是也許您可以使用su或sudo運行它：

su - user -c /home/user/script.sh

Answer 2

你可以用這個

ssh -i /path/to/key/file user@host

或在您的〜/ .ssh / config中，添加這樣的文本

Host foobar
    HostName 1.2.3.4
    Port 22
    User root
    IdentityFile ~/.ssh/id_rsa

現在，您可以這樣登錄

ssh foobar
