尝试从从节点 ssh 到 GIT 时权限被拒绝（公钥）

Question

所以我正在尝试为 Jenkins 设置一个 ssh 密钥。出于某种原因，我得到了：

Permission denied (publickey). 

完整的堆栈跟踪是：

[jenkins@ip-xx-xx-xx-xxx .ssh]$ ls
authorized_keys  id_rsa  id_rsa.pub  known_hosts
[jenkins@ip-xx-xx-x-xxx .ssh]$ ssh -vT ddennis@git.xxxxxx.com

我也在 git 中将 ssh 密钥设置为我的用户。
我跑了：

[jenkins@ip-xx-xx-xx-xxx .ssh]$ ssh-add -l
4096 9e:93:0c:12:4c:74:a6:e4:f0:eb:a1:28:d4:44:46:71 /home/jenkins/.ssh/id_rsa (RSA)

在我的从节点上，它与加载到 git 中的节点匹配。
我还将该密钥的副本复制到了我的授权密钥文件中。
玩了一段时间，任何建议都是有帮助的。

首先尝试生成不带密码的 ssh 密钥：这样您就不必担心 ssh-add。

ssh-keygen -t rsa -C "key for xxx access" -q -P ""

（不需要腻子as seen in "AWS Troubleshooting Instances Connecting"）
（不需要for the console, which creates ppk/pem ssh keys）

确保permissions are correct, both on the client and server side, regarding ssh。

确保您已正确复制服务器中的公钥：

~/ddennis/.ssh/authorized_keys 

（作为一条连续线）

之后，如果ssh -Tv可以工作，而Jenkins本身不工作，一般是因为Jenkins没有用同一个账号运行，也没有寻找同一套ssh密钥。
