AWS S3

For this contest we provide contest data via the s3://fintech80chengdu-topic storage bucket, which contains contest questions and dependency data.

- By the aws console (Not recommended, but intuitive and simple）

See Steps blew

- By the aws cli (Recommended, support large files and intermittent transfer, fast speed）

1. Install AWS CLI

If the AWS CLI is not installed on your EC2 instance, follow these steps to install it.

# For Amazon Linux or CentOS
sudo yum install aws-cli -y

# For Ubuntu
sudo apt-get update
sudo apt-get install awscli -y

2. Configure AWS CLI

Use the following command to configure the AWS CLI, entering your AWS access key and region information.

aws configure

You will need to provide the following information:

• AWS Access Key ID

• AWS Secret Access Key

• Default region name (e.g. ap-southeast-1)

• Default output format (you can choose json)

3. Sync Files

Use the aws s3 sync command to synchronize files from the S3 bucket to your EC2 instance.

Example:Assuming you want to sync files from CHENGDU80 topic S3 bucket named chengdu80-topic to the /home/ec2-user/myfiles directory on your EC2 instance, you would run:

aws s3 sync s3://fintech80chengdu-topic /your-local-folder --region ap-east-1

4. Verify Sync

After synchronization is complete, you can use the ls command to check the target directory and confirm that files have been successfully downloaded.

ls /home/ec2-user/myfiles
