Step 2: Configure your Amazon EC2 instance

When your Amazon EC2 instance is available, you can log into it and prepare it for first use.

Note

The following steps assume that you're connecting to your Amazon EC2 instance from a computer running Linux. For other ways to connect, see Connect to your Linux instance in the Amazon EC2 User Guide.

To configure your Amazon EC2 instance

You need to authorize inbound SSH traffic to your Amazon EC2 instance. To do this, create a new EC2 security group, and then assign the security group to your EC2 instance.
1. In the navigation pane, choose Security Groups.
2. Choose Create Security Group. In the Create Security Group window, do the following:
  - Security group name – Enter a name for your security group. For example: my-ssh-access
  - Description – Enter a short description for the security group.
  - VPC – Choose your default VPC.
  - In the Inbound rules section, choose Add Rule and do the following:
    Type – Choose SSH.
    
    Source – Choose My IP.
    
    Choose Add rule.
  On the bottom of the page, confirm the configuration settings and choose Create Security Group.
3. In the navigation pane, choose Instances.
4. Choose the Amazon EC2 instance that you launched in Step 1: Launch an Amazon EC2 instance.
5. Choose Actions, choose Security, and then choose Change Security Groups.
6. In Change Security Groups, select the security group that you created earlier in this procedure (for example, my-ssh-access). The existing default security group should also be selected. Confirm the configuration settings and choose Assign Security Groups.
Use the following command to protect your private key file from access. If you skip this step, the connection fails.
```
chmod 400 path_to_file/my-keypair.pem
```
Use the ssh command to log in to your Amazon EC2 instance, as in the following example.
```
ssh -i path_to_file/my-keypair.pem ubuntu@public-dns-name
```
You need to specify your private key file (.pem file) and the public DNS name of your instance. (See Step 1: Launch an Amazon EC2 instance).

The login ID is ubuntu. No password is required.

For more information about allowing connections to your Amazon EC2 instance and for Amazon CLI instructions, see Authorize inbound traffic for your Linux instances in the Amazon EC2 User Guide.
Download and install the latest version of the Amazon Command Line Interface.
1. Install unzip.
```
sudo apt install unzip
```
2. Download the zip file with the Amazon CLI.
```
curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
```
3. Unzip the file.
```
unzip awscliv2.zip
```
4. Install the Amazon CLI.
```
sudo ./aws/install
```
5. Confirm the version of the Amazon CLI installation.
```
aws --version
```
  The output should look like this:
```
aws-cli/2.9.19 Python/3.9.11 Linux/5.15.0-1028-aws exe/x86_64.ubuntu.22 prompt/off
```

Configure your Amazon credentials, as shown in the following example. Enter your Amazon access key ID, secret key, and default Region name when prompted.


aws configure
 
AWS Access Key ID [None]: AKIAIOSFODNN7EXAMPLE
AWS Secret Access Key [None]: wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
Default region name [None]: us-east-1
Default output format [None]:

You have to use a cqlsh connection to Amazon Keyspaces to confirm that your VPC endpoint has been configured correctly. If you use your local environment or the Amazon Keyspaces CQL editor in the Amazon Web Services Management Console, the connection automatically goes through the public endpoint instead of your VPC endpoint. To use cqlsh to test your VPC endpoint connection in this tutorial, complete the setup instructions in Using cqlsh to connect to Amazon Keyspaces.

You are now ready to create a VPC endpoint for Amazon Keyspaces.
