不能够通过SSH到新的命令行创建的实例 [英] Not able to SSH to new command line created instance
问题描述
我用下面的命令创建一个新的实例，
I'm creating a new instance by using the following command,
EC2-运行情况--keyXXXX密钥对--instance型t1.micro --instance启动关机 - 行为终止--user数据文件myscript.sh $ ami_id
和我的AMI是汇出默认AMI
我启动实例后，用从我的旧的实例以下code连接新实例，
after I launch the instance, used the following code from my older instance to connect new instance,
的ssh -i xxx_yyy.pem bitnami@xxxxxx.compute-1.amazonaws.com
和我无法连接这一点，有服务器没有响应，
And I can't connect this, there is no response from server,
任何人都可以请帮我在这??
Can anyone please help me in this??
在此先感谢。
推荐答案
典型的东西来检查试图连接到一个EC2实例时：
Typical things to check when trying to connect to an EC2 instance:
安全组 检查与实例相关联的安全组中的至少一个具有端口22（SSH）或端口3389（RDP）开到你的源IP地址范围（例如，一个特定的IP地址54.87.23.11/32，还是整个世界0.0.0.0 / 0 - 但后者是很差的安全习惯）。安全组是有状态的，所以你只需要打开内向访问和返回路径会自动工作。
Security Groups Check that at least one of the Security Groups associated with the instance has port 22 (SSH) or port 3389 (RDP) open to your source IP range (eg a specific IP address 54.87.23.11/32, or the whole world 0.0.0.0/0 -- but the latter is very poor security practice). Security Groups are stateful, so you only need to open Inbound access and the return path will automatically work.
公开IP地址 请确认您使用的是与实例相关联的公网IP地址。这可以在例如发射被分配（这会从池中分配一个随机的IP地址），也可以指定为弹性IP地址（这是可以分配分配给任何实例，你保留它，直到你一个静态IP地址释放回AWS）。
Public IP Address Confirm that you are using a Public IP address associated with the instance. This can either be assigned at instance launch (which will allocate a random IP address from a pool) or can be assigned as an Elastic IP Address (which is a static IP address that you can assign assign to any instance and you keep it until you release it back to AWS).
公开子网/路由 确认您的实例在公用VPC子网。这意味着，与子网相关联的路由表具有通过因特网网关的路由。
Public Subnet / Routing Confirm that your instance is in a "Public" VPC Subnet. This means that the Route Table associated with the Subnet has a route through an Internet Gateway.
AMI操作系统 我见过的情况下，人们尝试使用SSH到Windows实例，或RDP到Linux实例，因此也请检查您推出了正确的AMI您预期的操作系统。
AMI Operating System I've seen situations where people try to SSH to a Windows instance, or RDP to a Linux instance, so also check that you launched the correct AMI for your expected operating system.
