Question

我们有一个在Amazon AWS上运行的Rails应用程序。我们几乎每天都会推出一个新代码，连续几个月。

今天，当我尝试在那里部署新代码时，我收到了以下错误消息：

  * 2014-02-16 13:09:51 executing `deploy'
  * 2014-02-16 13:09:51 executing `deploy:update'
 ** transaction: start

这里发生了什么？从哪里开始寻找问题？

Answer 1

问题是宝石

净-SSH

最后一个版本（2.8.0）导致此问题。解决方案是卸载它：

gem uninstall net-ssh -v 2.8.0

然后将Gemfile添加到以前的版本中：

gem "net-ssh", "~> 2.7.0"

就是这样。

Answer 2

使用capistrano部署时遇到了同样的问题 Net :: SSH :: AuthenticationFailed：用户部署者@ IP

的身份验证失败

ssh-copy-id deployer@ip

这会将您的密钥添加到服务器，您无需密码即可登录。

Answer 3

卸载net-ssh 2.8.0后，也删除gemfile.lock。它会一直没问题。

Answer 4

请删除旧的net-ssh并安装如下更新，将其添加到您的gem文件中，或者可以在指定2.9.2版本的环境中安装它。

gem 'net-ssh', '~> 2.9.2'

它适用于我。

Answer 5

对于deploy.rb中的capistrano2

net-ssh 2.9.1 set :ssh_options, { config: false}
net-ssh 2.9.2 set :ssh_options, { config: false, number_of_password_prompts: 0 }

Capistrano无法部署代码，因为Net :: SSH :: AuthenticationFailed：身份验证失败
