Hadoop 的部分安装需要通过 ssh 与本地主机的无密码连接。说明很简单
$ ssh-keygen -t dsa -P '' -f ~/.ssh/id_dsa
$ cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
$ ssh -vv localhost
OpenSSH_6.9p1, LibreSSL 2.1.8

但它一直要求输入密码。我尝试了很多东西，但我会尽量缩短。
- 启用远程日志记录
- 以防万一我完全清理了我的 ~./ssh 目录然后生成了 key
- 出于好奇，我在计算机上尝试使用普通用户帐户，这些简单的步骤有效
- 我以前不得不摆弄 Git 的 ssh 和连接到远程服务器的工作
- 据我所知，/etc/ssh/是系统范围的，并且由于普通用户正在工作，我假设我不必使用它，尽管我确实尝试更改其中的几个参数以防万一
- 我创建了 RSA 和 DSA 以防万一
- 我将 ~/.ssh/authorized_keys 的权限更改为 600，但原始用户有 644，它仍然有效
所以总结了我尝试的步骤。我知道有很多关于这个问题的帖子，但我觉得这不是通常的嫌疑人。也许您可以为我指出正确的方向，这将有助于找出我的帐户与普通帐户之间的区别。
最佳答案
好吧，我终于找到了!我刚刚了解到/var/log/system.log 在那里我看到了这一点信息
User [me] not allowed because shell /usr/local/bin/zsh does not exist
所以我看了看
$ file /usr/local/bin/zsh
/usr/local/bin/zsh: broken symbolic link to ../Cellar/zsh/5.1/bin/zsh
断开的链接...
brew install zsh
瞧瞧!
