# Set up the Amazon Command Line Interface (Amazon CLI)
<a name="setup-awscli"></a>

In this step, you download and configure the Amazon CLI to use with Managed Service for Apache Flink.

**Note**  
The getting started exercises in this guide assume that you are using administrator credentials (`adminuser`) in your account to perform the operations.

**Note**  
If you already have the Amazon CLI installed, you might need to upgrade to get the latest functionality. For more information, see [ Installing the Amazon Command Line Interface](https://docs.amazonaws.cn/cli/latest/userguide/installing.html) in the *Amazon Command Line Interface User Guide*. To check the version of the Amazon CLI, run the following command:  

```
aws --version
```
The exercises in this tutorial require the following Amazon CLI version or later:  

```
aws-cli/1.16.63
```

**To set up the Amazon CLI**

1. Download and configure the Amazon CLI. For instructions, see the following topics in the *Amazon Command Line Interface User Guide*: 
   + [Installing the Amazon Command Line Interface](https://docs.amazonaws.cn/cli/latest/userguide/cli-chap-getting-set-up.html)
   + [Configuring the Amazon CLI](https://docs.amazonaws.cn/cli/latest/userguide/cli-chap-getting-started.html)

1. Add a named profile for the administrator user in the Amazon CLI `config` file. You use this profile when executing the Amazon CLI commands. For more information about named profiles, see [Named Profiles](https://docs.amazonaws.cn/cli/latest/userguide/cli-multiple-profiles.html) in the *Amazon Command Line Interface User Guide*.

   ```
   [profile adminuser]
   aws_access_key_id = adminuser access key ID
   aws_secret_access_key = adminuser secret access key
   region = aws-region
   ```

   For a list of available Amazon Regions, see [Regions and Endpoints](https://docs.amazonaws.cn/general/latest/gr/rande.html) in the *Amazon Web Services General Reference*.
**Note**  
The example code and commands in this tutorial use the us-east-1 US East (N. Virginia) Region. To use a different Region, change the Region in the code and commands for this tutorial to the Region you want to use.

1. Verify the setup by entering the following help command at the command prompt: 

   ```
   aws help
   ```

After you set up an Amazon account and the Amazon CLI, you can try the next exercise, in which you configure a sample application and test the end-to-end setup.
