Using the Amazon unified command line interface:

• For enabling logging first save locally the current distribution config:
  aws cloudfront get-distribution-config –id <application_cfn_distribution_id> –query “DistributionConfig” > /tmp/cf-distribution.json
• Edit and replace “Logging” element in /tmp/cf-distribution.json with the below section:
  “Logging”: {
  “Bucket”: “<s3_bucket_name>”,
  “Prefix”: “cloudfrontlogs”,
  “Enabled”: true,
  “IncludeCookies”: false
  },
• Retrieve the current ETag of your CloudFront distribution:
  aws cloudfront get-distribution-config –id <application_cfn_distribution_id> –query “ETag”
• Update the CloudFront distribution using the edited config and the above Etag:
  aws cloudfront update-distribution –id <application_cfn_distribution_id> –distribution-config file:///tmp/cf-distribution.json –if-match <application_cfn_distribution_etag>
