无法通过腻子连接到Amazon EC2实例 [英] Unable to connect to amazon EC2 instance via PuTTY

问题描述

我在亚马逊网络服务（AWS）创建亚马逊EC2的一个新实例通过的指的是文档。我甚至增加这样的SSH规则：

I created a new instance of Amazon EC2 in Amazon Web Services (AWS) by referring to the documentation. I even added a SSH rule like this:

Port: 22  
Type: SSH  
Source: <My IP address>/32

我下载了质子交换膜文件，转换成 .ppk 文件中使用 PuTTYGEN 。然后，我添加主机名腻子是这样的：

I downloaded the .pem file, converted it into .ppk file by using PuTTYGEN. Then I added host name in PuTTY like this:

ec2-user@<public_DNS>

我选择了默认设置补充说，登录.ppk文件腻子，我得到这个错误：

I selected default settings, added that .ppk file to PuTTY, logged in and I got this error:

甚至<一href="http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/TroubleshootingInstancesConnecting.html#TroubleshootingInstancesConnectionTimeout"相对=nofollow>问题解答链接并没有帮助我。
我也越来越在系统日志此错误：

Even trouble shooting link didn't help me.
I'm also getting this error in system logs:

我如何通过腻子连接到我的Amazon EC2实例？

How can I connect to my Amazon EC2 instance via PuTTY?

推荐答案

检查事项尝试连接到Amazon EC2实例时：

Things to check when trying to connect to an Amazon EC2 instance:

• 安全组：确保安全组允许的入所需的端口访问（例如80，22），相应的IP地址范围（例如： 0.0.0.0/0 ）。这解决了大部分问题。
• 公开IP地址：查看您正在使用该实例的正确的公网IP​​地址。如果实例停止和启动，它的也许的收到一个新的公网IP​​地址（具体取决于已配置）。
• VPC配置：访问是在一个虚拟私有云（VPC）需要推出一个EC2实例：
  • 的互联网网关
  • A 路由表子网连接到Internet网关
  • NACLs （网络ACLS）通流量允许
  • Security Group: Make sure the security group allows inbound access on the desired ports (eg 80, 22) for the appropriate IP address range (eg 0.0.0.0/0). This solves the majority of problems.
  • Public IP Address: Check that you're using the correct Public IP address for the instance. If the instance is stopped and started, it might receive a new Public IP address (depending on how it has been configured).
  • VPC Configuration: Accessing an EC2 instance that is launched inside a Virtual Private Cloud (VPC) requires:
    • An Internet Gateway
    • A routing table connecting the subnet to the Internet Gateway
    • NACLs (Network ACLS) that permit through-traffic

    如果您能够启动并连接到另一个实例在同一个子网，那么VPC配置似乎是正确的。

    If you are able to launch and connect to another instance in the same subnet, then the VPC configuration would appear to be correct.

    另外要检查将是实际的配置操作系统在该实例本身。某些软件可能会影响使Web服务器/ ssh守护进程运行不正常的配置。当然，这是很难确定无需连接到该实例。

    The other thing to check would be the actual configuration of the operating system on the instance itself. Some software may be affecting the configuration so that the web server / ssh daemon is not working correctly. Of course, that is hard to determine without connecting to the instance.

    如果您是从一个标准的Linux亚马逊的AMI启动， SSH 将随时正常工作。该网站的服务器（端口80）将需要安装软件和配置上的实例，这是你的责任，以维护。

    If you are launching from a standard Amazon Linux AMI, ssh would work correctly anytime. The web server (port 80) would require installation and configuration of software on the instance, which is your responsibility to maintain.
