localhost：權限被拒絕（公鑰，密碼，鍵盤互動）

我試圖在 Mac OS 中執行 Hadoop，但出現以下錯誤，

$ hstart

WARNING: This is not a recommended production deployment configuration.

我查看了Google並找到了類似的文章。我提到 Permission denied 是錯誤，我沒有passwordless ssh正確設置。例如，ssh localhost 不應該要求輸入密碼。

我執行ssh localhost它，它確實要求輸入密碼。作為問題的解決方案，有人提到執行命令，

cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

我這樣做了，然後當我執行 ssh localhost 時，我被要求輸入密碼（而不是密碼）。

$ ssh localhost

Enter passphrase for key '/Users/chaklader/.ssh/id_rsa':

原來的問題沒有解決。提到另一個文章來執行命令chmod og-wx ~/.ssh/authorized_keys，在我這樣做之後，它仍然保持不變。

我試圖檢查 id_rsa 裡面的內容並找到資訊，

$ cat ~/.ssh/id_rsa.pub
ssh-rsa

這對我來說看起來像相同的資訊。這裡錯過了什麼？

私鑰不應受密碼保護。 檢查這篇文章以檢查

您的私鑰的權限是否設置正確？應設置為：

 chmod 600  ~/.ssh/id_rsa
