我有3個CentOS虛擬機，並試圖從任何主機設置無密碼的SSH到任何其他主機。 （稱他們爲db01，db02，dbmgr）無密碼的SSH工作的一種方式，但不是其他
我複製到的.ssh的RSA公鑰/ authorized_keys中 即
db01 - > SSH/authorized_keys中已從db02公共密鑰的條目，dbmgr
db02 - > SSH/authorized_keys中具有公共密鑰的條目從db01，dbmgr
dbmgr - > SSH/AUTH。 orized_keys具有db01公共密鑰的條目，db02
我已經驗證了整個主機

，我能夠ssh到db01到db02和周圍的其他方法的公共密鑰字符串沒有密碼我可以從dbmgr ssh到db01和db02沒有密碼。
但試圖ssh到dbmgr從db01或db02要求輸入密碼。
我不知道我錯過了什麼。
編輯：解決它，通過查看日誌。日誌表明確實存在許可問題。

你是否檢查訪問'〜/ .ssh/authorized_keys'的權限？ 「sshd」服務器在調試模式下寫入密鑰的是什麼？ – Jakuje
我在哪裏檢查sshd輸出，以及如何在調試模式下運行它？對authorized_keys的訪問必須是正確的，否則我也會面臨同樣的問題，在sshing到另一個主機。 – anu
把'LogLevel DEBUG3'放在你的'sshd_config'中，重新啓動'sshd'，你應該在日誌文件'/ var/log/secure'，'/ var/log/messages'中看到日誌。 – Jakuje
