Github 權限被拒絕（公鑰）SSH 密鑰在錯誤的目錄中？

Question

我最近在 AWS EC2 上安裝了這個堆棧： https ://aws.amazon.com/marketplace/pp/B00NO1HJ56/ref=srh_res_product_title?ie = UTF8&sr = 0-2&qid =1461119036279

實例的系統日志顯示 SSH 密鑰安裝在此處：

Generating public/private rsa key pair.
Your identification has been saved in /etc/ssh/ssh_host_rsa_key.
Your public key has been saved in /etc/ssh/ssh_host_rsa_key.pub.

我已將公鑰添加到我的 Github 帳戶並且指紋匹配。

克隆存儲庫時，我得到：權限被拒絕（公鑰）。

從 Github 幫助部分https://help.github.com/articles/error-permission-denied-publickey

我運行： ssh -vT git@github.com 並得到：

我似乎 ssh 代理正在搜索 /home/bitnami/.ssh/ 但密鑰位於 /etc/ssh

這是/home/bitnami/.ssh的內容

authorized_keys
known_hosts

這是/etc/ssh的內容

moduli
ssh_host_dsa_key
ssh_host_ecdsa_key.pub
ssh_host_rsa_key
ssh_config
ssh_host_dsa_key.pub
ssh_host_ed25519_key
ssh_host_rsa_key.pub
sshd_config
ssh_host_ecdsa_key
ssh_host_ed25519_key.pub
ssh_import_id

如果我檢查將哪些密鑰添加到 ssh 代理，我會得到：

$ ssh-add -l I get:
The agent has no identities.

這是否只是通過使用 ssh-add 將我在 /etc/ssh/ 中的公鑰添加到 ssh 代理的問題，以便它知道在哪里查找？

我不明白為什么密鑰沒有安裝在 /etc/hosts 而不是主目錄中。

Answer 1

解決方案只是忽略 /etc/ssh 中的鍵。 AWS 使用這些密鑰來訪問實例並且屬於系統而不是用戶。

所以我剛剛為 bitnami 用戶生成了新密鑰，這些密鑰現在正確地位於 /home/.ssh/

我現在可以從 Github 中提取我的 repo。
