我使用Python来启动EC2实例后，我得到跑我的实例的状态，我想SCP一个shell脚本，并通过ssh运行它。

I am using Python to launch an ec2 instance, after I get "running" state of my instance, I am trying to SCP a shell script and run it via ssh.

我收到以下错误

SSH：连接到主机ec2-xx-xxx-xxx-xxx.compute-1.amazonaws.com端口22：连接被拒绝

"ssh: connect to host ec2-xx-xxx-xxx-xxx.compute-1.amazonaws.com port 22: Connection refused"

当我检查在控制台中，状态检查是初始化，一旦它改变了2/2检查合格，我能SSH或运行任何脚本。

When I check in the console, the Status check is "Initializing", once It changes "2/2 checks passed", I am able to ssh or run any script.

有什么办法，我可以通过Python博托API获得状态检查？

Is there any way I can get the "status check" via python boto API?

我使用Python 2.7.5+， 博托2.19.0

I am using Python 2.7.5+, boto 2.19.0

在此先感谢。

推荐答案

简单的方法是使用检查口新创建的实例的22可达与否插槽模块

Simple way is to check the port 22 of the newly created instance is reachable or not by using socket module

import socket
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
try:
     s.connect(('hostname', 22))
     print "Port 22 reachable"
except socket.error as e:
     print "Error on connect: %s" % e
s.close()

当你将能够达到22端口，那么你可以调用ssh来了。

When you will able to reach the port 22 then you can invoke ssh to it.
