git - 使用 cron 作业推送到 GitHub——权限被拒绝(公钥)

Question

我创建了一个 SSH key (在 the official tutorial 之后)，将其添加到 GitHub 并创建了一个 Bash 脚本，用于提交单个文件并将其推送到我在 Github 上的存储库。当我从命令行运行此脚本时，一切正常并推送更新。但是，当我使用 crontab -e 设置作业时，推送会生成以下错误:

Permission denied (publickey).
fatal: The remote end hung up unexpectedly

我已经编辑了用户的 crontab (crontab -e)，即我没有使用 sudo crontab -e。我正在运行 Ubuntu 12.04。

如果不是用户问题(您以 root 身份运行作业，缺少正确的 $HOME/.ssh 文件夹)，它可能是 passphrase issue :

turns out I was mistaken, and the ssh key was password protected (with keychain loading the ssh-agent), hence why it failed from a script but not when running from the bash session.
Adding . ~/.keychain/$HOSTNAME-sh to my script resolved the problem.

密码位在“Not able to ssh in to remote machine using shell script in Crontab”中有详细说明:

You can make ssh connections within a cron session. What you need is to setup a public key authentication to have passwordless access.
For this to work, you need to have PubkeyAuthentication yes in each remote server's sshd_config.
