嗨，我正在我的机器上安装hadoop，我创建了一个新组和组下的一个用户

[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 .   . .| |               . | |
| |                 | |                 |

我确实生成了私钥，密码为空，并移到了授权的\u密钥。下一步是 cat $HOME/.ssh/id_rsa.pub >> $HOME/.ssh/authorized_keys .
但在连接到ssh localhost时，我的新用户仍然要求我输入密码。我没有产生。
