Lab 7 - Simple Storage Service (S3) Glacier

Overview​

This week's lab will cover the following:

  • Modifying the wordpress source code in preparation for Lab 8
  • Creating a public Simple Storage Service (S3) bucket
  • Uploading files to a Simple Storage Service (S3) bucket

Investigation 1: Wordpress Source Code Modification​

Download and Unzip - Local Computer​

  1. On your local computer, download the current Wordpress source code from here: https://wordpress.org/latest.zip
  2. Unzip the file. You should end up with a wordpress directory. (Do not delete the original .zip file)

Modify Wordpress Configuration File​

Duplicate and Open Configuration File​

  1. In the local wordpress folder, find a file called: wp-config-sample.php
  2. Duplicate this file, and call it: wp-config.php
  3. Open wp-config.php in a text editor. You will want something that supports syntax highlighting, such as Visual Studio Code.

Adding Database Connector Info as Environment Variables​

In this file (wp-config.php), you will be adding database connector information as environment variables, not the actual connector information. (We'll add that information later.)

Find the following lines and add the bolded values:

  1. define('DB_NAME', getenv('DB_NAME'));
  2. define('DB_USER', getenv('DB_USER'));
  3. define('DB_PASSWORD', getenv('DB_PASSWORD'));
  4. define('DB_HOST', getenv('DB_HOST'));

Adding Authentication Unique Keys and Salts as Environment Variables​

In the same file (wp-config.php), you'll be adding the authentication keys and salts as environment variables.

Find the following lines and add the bolded values:

  1. define('AUTH_KEY', getenv('AUTH_KEY'));
  2. define('SECURE_AUTH_KEY', getenv('SECURE_AUTH_KEY'));
  3. define('LOGGED_IN_KEY', getenv('LOGGED_IN_KEY'));
  4. define('NONCE_KEY', getenv('NONCE_KEY'));
  5. define('AUTH_SALT', getenv('AUTH_SALT'));
  6. define('SECURE_AUTH_SALT', getenv('SECURE_AUTH_SALT'));
  7. define('LOGGED_IN_SALT', getenv('LOGGED_IN_SALT'));
  8. define('NONCE_SALT', getenv('NONCE_SALT'));

Confirm the values are correct and save the file.

Zip As New File and Rename - Local Computer​

Warning: Make sure you only zip the wordpress directory, not the directory with the version number.

  1. Find the wordpress folder on your local computer.
  2. Zip the entire wordpress directory, not just the files inside. (Use the zip compression protocol. Don't use something else like .rar.)
  3. Rename your new zip file: wordpress-6.7.2-modded.zip (Use whatever version the source zip file has.)

Investigation 2: Creating an Simple Storage Service (S3) Bucket​

Start your session in the Learner Lab by clicking on the Start Lab button. You are going to create an S3 bucket and upload your wordpress configuration files.

From the Console Home navigate to Storage > S3.

  • Navigate to Amazon S3
  • Click Create bucket

General configuration​

  • General purpose: selected
  • Bucket name: senecausername-wordpress

Object Ownership​

  • ACLs disabled (recommended): selected

Block Public Access settings for this bucket​

  • Block all public access: unchecked
  • I acknowledge that the current settings might result in this bucket and the objects within becoming public: checked

Bucket versioning​

  • Enable

Default encryption​

  • Accept the defaults

Bucket key​

  • Enable

Scroll down and click Create bucket

Once your bucket has created, click on your bucket's name (ie: candice-wordpress).

  • Click Upload
  • Click Add files
  • Select your wordpress-modded zip file

Make note of the Destination location: ie: s3://candice-wordpress. You will need this for your next lab.

  • Click Upload

Lab 7 Sign-Off (Show Instructor)​

Take screenshots showing the following:

  • Your S3 bucket

Exploration Questions​

  1. What is S3?
  2. Describe the process of creating an S3 bucket as outlined in the lab instructions.
