fedora中沒有authorized_keys文件

Question

嗨，我要在我的機器上安裝hadoop，我創建了一個新組，並在該組下創建了一個用戶

[hduser@localhost ~]$ ssh-keygen -t rsa -P "" Generating
public/private rsa key pair. Enter file in which to save the key
(/home/hduser/.ssh/id_rsa):  Created directory '/home/hduser/.ssh'.
Your identification has been saved in /home/hduser/.ssh/id_rsa. Your
public key has been saved in /home/hduser/.ssh/id_rsa.pub. The key
fingerprint is: 30:1f:1f:5d:ef:52:16:41:7e:41:81:b4:62:17:87:36
hduser@localhost.localdomain The key's randomart image is:
+--[ RSA 2048]----+ |            .o*Oo| |           . E=.o| |      o . .ooo..=| |       + o..o  +.| |        S .   . .| |               . | |
| |                 | |                 |
+-----------------+

我確實生成了具有空密碼的私鑰，並移到了authorized_keys。 下一步是cat $HOME/.ssh/id_rsa.pub >> $HOME/.ssh/authorized_keys 。

但是仍然在連接到ssh localhost時，我的新用戶要求我輸入密碼。 我沒有產生。

Answer 1

.ssh目錄和authorized_keys文件應由登錄用戶擁有，並且只能由該用戶讀取。 如果默認的ssh配置是組可讀或全局可讀的，則將拒絕訪問。

檢查/ var / log / audit中可能解釋的條目。
