如何在Amazone的EC2实例中运行代码？ [英] How to run a code in an Amazone's EC2 instance?

问题描述

我对EC2的功能几乎一无所知。我创建了一个Amazon Web Service（AWS）帐户。然后，我启动了一个EC2实例。

I understand nearly nothing to the functioning of EC2. I created an Amazon Web Service (AWS) account. Then I launched an EC2 instance.

现在我想在此实例中执行Python代码，但我不知道该如何继续。是否有必要在实例中的某处加载代码？还是在Amazon的S3中将其链接到实例？

And now I would like to execute a Python code in this instance, and I don't know how to proceed. Is it necessary to load the code somewhere in the instance? Or in Amazon's S3 and to link it to the instance?

在哪里有指南解释可能的实例用法？在没有用户指南的情况下，我感觉就像是在飞碟的仪表板前一样。

Where is there a guide that explain the usages of instance that are possible? I feel like a man before a flying saucer's dashboard without user's guide.

推荐答案

这是一个非常简单的过程，可将Python脚本从在EC2实例本地运行。

Here's a very simple procedure to move your Python script from local to EC2 Instance and run it.

> 1. scp -i <filepath to Pem> <filepath to Py File> ec2-user@<Public DNS>.compute-1.amazonaws.com:<filepath in EC2 instance where you want
> your file to be>
> 2. Cd to to the directory in EC2 containing the file. Type Python <Filename.py> There it executed.

以下是一些喜欢逐步显示内容的人的具体示例：

Here's a concrete examples for those who likes things shown step-by-step:

1. 在您的本地目录中，使用以下代码创建python脚本： print（ Hello AWS）


2. 假设您已经设置了AWS，并且想要在EC2中运行此脚本，则需要将文件SCP（安全复制协议）存储到EC2中的目录中。举个例子：

-我的pem文件路径是〜/ Desktop / random.pem。

-我的py文件的文件路径是〜/ Desktop / hello_aws.py

-我的公共DNS是ec22-34-12-888

-ec2我希望脚本存放在的目录位于/ home / ec2-user

-因此，我在本地终端中运行的完整命令是：

- My filepath to pem is ~/Desktop/random.pem.
- My filepath to py file is ~/Desktop/hello_aws.py
- My public DNS is ec22-34-12-888
- The ec2 directory where I want my script to be is in /home/ec2-user
- So the full command I run in my local terminal is:




scp -i〜/ Desktop / random.pem〜/ Desktop / hello_aws.py [e-mail] ：/ home / ec2-user

scp -i ~/Desktop/random.pem ~/Desktop/hello_aws.py [e-mail]:/home/ec2-user







1. 现在将ssh转到ec2实例cd到/ home / ec2-user（或您放置文件的任何位置）和Python hello_aws.py
