linux - Github 权限被拒绝 (publickey) SSH key 位于错误的目录中？

Question

我最近在 AWS EC2 上安装了这个堆栈: https://aws.amazon.com/marketplace/pp/B00NO1HJ56/ref=srh_res_product_title?ie=UTF8&sr=0-2&qid=1461119036279

实例的系统日志显示 SSH key 安装在此处:

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.

我已将公钥添加到我的 Github 帐户并且指纹匹配。

克隆存储库时我得到: 权限被拒绝(公钥)。

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

我运行:ssh -vT git@github.com 并得到:

我似乎 ssh 代理正在搜索/home/bitnami/.ssh/但 key 位于/etc/ssh

这是/home/bitnami/.ssh的内容

authorized_keys
known_hosts

这是/etc/ssh 的内容

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

如果我检查将哪些 key 添加到 ssh 代理中，我会得到:

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

这是否只是使用 ssh-add 将/etc/ssh/中的公钥添加到 ssh 代理，以便它知道在哪里查找？

我不明白为什么 key 没有安装在/etc/hosts 中而不是安装在主目录中。

Answer 1

解决方案很简单，忽略/etc/ssh 中的 key 。这些 key 由 AWS 用于访问实例，属于系统而不是用户。

所以我刚刚为 bitnami 用户生成了新 key ，这些 key 现在正确地位于/home/.ssh/

我现在可以从 Github 中提取我的存储库。
