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.

现在我想在这个实例中执行一个Python代码，我不知道如何进行.是否有必要在实例中的某处加载代码?还是在 Amazon 的 S3 中并将其链接到实例?

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?

哪里有解释实例可能用法的指南?在没有用户指南的飞碟仪表盘前，我感觉自己像个男人.

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

这是将 Python 脚本从本地移动到 EC2 实例并运行它的一个非常简单的过程.

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.

这里有一个具体的例子，适合喜欢循序渐进的事物的人:

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

1. 在您的本地目录中，使用以下代码创建一个 python 脚本:print("Hello AWS")
2. 假设您已经设置了 AWS 并且您想在 EC2 中运行此脚本，您需要将您的文件 SCP(安全复制协议)到 EC2 中的目录.举个例子:

- 我的 pem 文件路径是 ~/Desktop/random.pem.
- 我的 py 文件路径是 ~/Desktop/hello_aws.py
- 我的公共 DNS 是 ec22-34-12-888
- 我希望我的脚本所在的 ec2 目录在/home/ec2-user
- 所以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 ssh 到您的 ec2 实例，cd 到/home/ec2-user(或您放置文件的任何位置)和 Python hello_aws.py
