身份验证失败使用Capistrano

标签： ruby-on-rails capistrano puma net-ssh

我正在学习本教程：

https://www.sitepoint.com/deploy-your-rails-app-to-aws/

应用程序已完全创建并在开发中运行（包括数据库）。 密钥已被添加到GIT和SSH中，但是从教程中我非常确定它们中的哪一个到底在哪里。

这就是我得到的错误。

我试图在我发现的帖子中建议几乎所有修复。没有什么对我有用。

以下是更多详情：

$ gem list net

我的config/deply/production.rb文件是（一条未注释的行）：

不知道如何解决这个问题并继续前进？

在对Capistrano中的timelist.Add(DateTime.Now.AddMinutes(i + 2)); 错误进行排查时，首先降低到较低级别并测试与authentication failed的连接是很有用的。这样你就可以弄清楚它是否真的是一个Capistrano问题，或者是一个更基本的SSH连接问题。

在这种情况下，Capistrano表示无法以ssh用户身份连接到52.87.233.215。让我们手动验证：

deploy

ssh -v deploy@52.87.233.215 标记转储了一堆详细日志记录，以便我们可以看到正在尝试的身份验证方法。

如果获得-v，则表示您没有在服务器上正确安装公钥。换句话说，服务器无法验证您是谁，并拒绝访问。

要安装公钥，请从本地计算机复制此文件的内容：

permission denied (publickey)

将这些内容粘贴到服务器上的文件：

~/.ssh/id_rsa.pub

确保~deploy/.ssh/authorized_keys 用户拥有并可访问~deploy/.ssh/authorized_keys：

deploy

现在再次尝试$ ls -ld ~deploy/.ssh drwxr-xr-x 2 deploy deploy 4096 Jun 16 2015 /home/deploy/.ssh $ ls -ld ~deploy/.ssh/authorized_keys -rw------- 1 deploy deploy 1023 Sep 12 02:13 /home/deploy/.ssh/authorized_keys 命令：

ssh

它应该有用，如果是的话，Capistrano现在应该也能正常工作。

答案 1 :(得分：0)

对我有用的唯一解决方案是：

ssh -i ~/.ssh/contactbook.pem ec2-user@ec2-54-226-156-103.compute-1.amazonaws.com
su - deploy
chmod 400 /home/deploy/.ssh/authorized_keys
chown deploy:deploy /home/deploy -R

仅在命令之后：

ssh -v deploy@54.226.156.103

和

cap production deploy

成功。
