Capistrano 3部署失败连接到GitHub - 权限被拒绝（公钥）

问题描述

我有以下部署脚本，搭配Capistrano v3和capistrano / symfony gem。我正在使用Ubuntu 14.4
部署到AWS EC2实例，我正在使用从AWS下载的.pem文件进行连接。在我的deploy.rb中有以下内容：

  set：pty，true 
 
 set：ssh_options， {
 user：'ubuntu'，
 keys：['/Users/myuser/Sites/Myproject.pem']，
 forward_agent：true，
 auth_methods：[publickey ] 
 
 $ b $ / code> 

使用


  bundle exec cap staging deploy --trace 
  

脚本连接正常，但在此失败

我不知道为什么forward_agent不工作？ / p>



我一直在尝试遵循本指南 -

但是当我到达这个时候

  echo$ SSH_AUTH_SOCK
  

它打印出一个空行。

在服务器上它说没有找到命令

  sshd_config 
  

解决方案

仔细检查运行Capistrano的用户是否有 ssh-agent ssh-add 编辑了相关的键。

以下是一些不错的指南：

I have the following deploy script set up with Capistrano v3 and capistrano/symfony gem. I am deploying to an AWS EC2 instance with Ubuntu 14.4I am connecting with a .pem file downloaded from AWS. I have the following in my deploy.rb

set :pty, true

set :ssh_options, {
  user: 'ubuntu',
  keys: ['/Users/myuser/Sites/Myproject.pem'],
  forward_agent: true,
  auth_methods: ["publickey"]
}

when deploying with

bundle exec cap staging deploy --trace

The script connects fine but fails on this

INFO [4fd1b02c] Running /usr/bin/env git ls-remote --heads [email protected]:MyName/Myproject.git as [email protected]

I don't know why forward_agent is not working?

I have been trying to follow this guide - https://developer.github.com/guides/using-ssh-agent-forwarding/#testing-ssh-agent-forwarding

but when I get to this

echo "$SSH_AUTH_SOCK"

It prints a blank line.

Also if I run this on the server it says command not found

sshd_config

解决方案

Double-check that the user running Capistrano has ssh-agent running and has ssh-added the relevant key.

Here are some good guides:
