SSH 无密码问题

我开始进行无密码 SSH 会话。现在我可以像这样连接到我的服务器：

bash-3.2$ ./dev2
Enter passphrase for key '/Users/roger/.ssh/id_rsa': 
Welcome to Ubuntu 16.04.3 LTS (GNU/Linux 2.6.32-042stab120.11 x86_64)

 * Documentation:  https://help.ubuntu.com
 * Management:     https://landscape.canonical.com
 * Support:        https://ubuntu.com/advantage

0 packages can be updated.
0 updates are security updates.

现在我编辑 sshd_config 并在末尾添加以下内容：

RSAAuthentication yes
PubkeyAuthentication yes
AuthorizedKeysFile    .ssh/authorized_keys

重新启动服务器但 ssh 仍然要求我输入密码。

我应该怎么办？

pass phrase在这种情况下，您在创建时已经拥有密码，因此如果您在未使用pass phraseSSH 连接的情况下连接，则应使用以下命令创建新密钥：

**[test@test test]$ ssh-keygen**
Generating public/private rsa key pair.
Enter file in which to save the key (/home/test/.ssh/id_rsa):
Created directory '/home/test/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/test/.ssh/id_rsa.
Your public key has been saved in /home/test/.ssh/id_rsa.pub.
The key fingerprint is:
ac:5e:9a:72:c6:cd:82:9c:cd:1f:bc:4d:de:f9:50:d9 tanto@hlink_backup_086
The key's randomart image is:
+--[ RSA 2048]----+
|                 |
|                 |
|                 |
|       .       o |
|        S     o E|
|       o     .   |
|   . *.o+ . .    |
|    =.B+o* . o   |
|     ++oo o o..  |
+-----------------+

在步骤中Enter passphrase,你应该输入空。创建后，你可以将密钥添加到远程服务器的id_rsa.pub文件夹中，然后检查权限并使用 chmod 600 更改文件 authorized_keys：.ssh/authorized_keys

[root@test test]# chmod -R 600 /home/test/.ssh/authorized_keys
[root@test test]# ls -l /home/test/.ssh/authorized_keys
-rw------- 1 test test 1212 Jul 12 14:17 /home/test/.ssh/authorized_keys
