Question

我试图从Ubuntu ssh并使用Windows中的Putty \ Filezilla连接到我从AWS Marketplace的AMI创建的EC2实例，但我总是收到以下错误（我已经尝试过root ，ec2_user，bitnami和ubuntu作为用户名）：

OpenSSH_6.7p1 Ubuntu-5ubuntu1.3, OpenSSL 1.0.1f 6 Jan 2014

我创建了一个新的密钥对，并在Windows上使用了Puttygen，但仍然是同样的错误。

为什么？

Bitnami开发人员，

要连接到基于Bitnami的Amazon Web Services实例，您必须使用bitnami作为用户名，并使用您在使用Amazon EC2控制面板启动服务器时选择或生成的私有SSH密钥。请注意，您需要使用选项-i为SSH命令指定SSH密钥。例如，SSH命令看起来像：

ssh -i / path / to / your / ssh_key bitnami @ your_ec2_instance_dns_name

您需要指定SSH密钥，因为bitnami用户默认情况下没有密码，也因为我们已禁用SSH连接的密码。如果您愿意，可以在连接后启用它。

另请注意，登录后，您可以使用sudo实用程序在必要时通过运行命令sudo su成为root用户。

希望它有所帮助，
