从身份验证套接字读取响应长度时出错

Question

在我的 ruby rails 项目中，我使用 capistrano、unicorn、postgresql 和 nginx 来部署我的项目。当我运行 cap production git:check 我收到这个错误：

Error reading response length from authentication socket.

日志跟踪：

我读了一些 posts 但我想不出任何解决办法。

Answer 1

我不确定为什么会发生这种情况，但我已经在我的许多部署中看到它并且它们继续完美地工作。我觉得这个错误可以忽略。

Answer 2

TL;DR

# start/restart ssh-agent
eval "$(ssh-agent -s)"

# add the desired ssh-key
ssh-add ~/.ssh/id_rsa

有关详细信息，请参阅：https://help.github.com/articles/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent/。

我过去也遇到过同样的问题，这个 post 帮我解决了很多问题： http://www.antleon.com/2014/04/rails-capistrano-deployment-ssh-error-reading-response-length-from-authentication-socket/

希望对您有所帮助。

Answer 3

当我遇到这种情况时，是因为 ssh-agent 不再是运行。我重新启动它并检查了运行 ssh-add -L

时是否列出了一个密钥
