4. Create your free account on AWS - http://aws.amazon.com/free/
5. Part One: Create an EC2 instance In AWS-speak creating a new virtual server is called an “instance”. “Spinning up an EC2 instance” is a phrase you will hear quite often which just refers to starting a new EC2 instance. EBS refers to the “hard drive” that is attached to the EC2 instance. It’s where all the system files will reside.
6. Step 1: From the AWS Management Console click on the EC2 tab
7. Step 2: Click on “Launch Instance” and select Quick Launch Wizard (Enter the Instance name, create a new key and select the Amazon Linux AMI)
8. Step 3: Select Amazon Linux AMI (Under Instance details make sure t1.micro is selected it’s part of the free trial, then select Launch)
9. Step 4: Your instance is being created
10. Step 5: Add rules to the Default Security Group to allow inbound access to EC2 (port 20-21 = ftp, port 22 = ssh and port 80 = http)
11. Step 6: Assign an IP address by selecting Elastic IP’s
12. Step 7: Right click on the IP address and select Associate. Assign it to your new instance.
13. Step 8: Select your new Instance and right click on it (this contains some very useful information you might need later on)
14. Part Two: Configure your EC2 instance Now that the EC2 instance has been created it’s time to install the LAMP (Linux, Apache, MySQL and PHP) stack which we’ll need before you can install WordPress. The Linux kernel was preinstalled when the EC2 instance was created. Apache and PHP will be installed in this section. MySQL will be installed in the next section.
15. There are two ways you can connect to EC2, one is to right click on the EC2 instance name and launch a Java SSH client. The other way is to use a command line SSH client such as Terminal.app on the Mac. This tutorial will use Terminal. Step 1: Connect to the EC2 instance
16. From Terminal go to the directory that contains <filename>.pem (the file contains your credentials to access the EC2 instance.) Change the permission of the file: chmod 400 [filename].pem Connect to your EC2 instance: ssh -i [filename].pem ec2-user@[Elastic IP] Switch to superuser: sudo su Install any new updates: sudo yum update To install Apache: yum install httpd Start service: service httpd start Start service automatically: chkconfig httpd on Install PHP: yum install php php-mysql Restart Apache web service daemon: service httpd restart Step 2: Install Apache and PHP
17. Part Three: Create an RDS MySQL* instance * The fine print. As of July 2012 AWS only offers a free 2 month trial of RDS MySQL. An alternative is to install MySQL on your EC2 instance, those instructions are included in the appendix.
18. Step 1: Click on the RDS tab and select Launch DB Instance
19. Step 2: Select MySQL Community Edition
20. Step 3: Select db.t1.small, no for Multi-AZ (db.t1.small is part of the Free Trial. Remember the Master User Name and User Password for WordPress)
21. Step 4: Enter a Database Name (Remember the Database Name for WordPress)
22. Step 5: Select the defaults
23. Step 6: Select Launch DB Instance
24. Step 7: The database may take 5 minutes to create
25. Step 8: Click on DB Security Groups and select default
26. Step 9: Click on Select and pick the EC2 Security Group
27. Step 10: Click on your database and review the information (Remember the Endpoint for WordPress)
28. Part Four: Install WordPress WordPress will be installed at the root of your EC2 Instance.
29. From Terminal go to the directory that contains <filename>.pem (the file contains your credentials to access the EC2 instance.) Change the permission of the file: chmod 400 [filename].pem Connect to your EC2 instance: ssh -i [filename].pem ec2-user@[Elastic IP] Switch to superuser: sudo su Change to the root directory: cd /var/www Download the latest WordPress package: wget http://wordpress.org/latest.tar.gz Extract WordPress: tar -xzvf latest.tar.gz Move WordPress to the html folder: rmdir html mv wordpress html Delete the WordPress tar file: rm latest.tar.gz Change permissions on the directory: cd /var/www/ chmod o+w html cd /var/www/html sudo chown ec2-user . Step 1: Download WordPress
30. Step 2: Point your browser to the Elastic IP address and create the config file
31. Step 3: Enter the configuration details and submit RDS Endpoint
32. Step 4: Finish the installation of WordPress
33. Step 4: Goto your Elastic IP address and visit your new blog
34. Part Five: Configure S3 S3 will be used to serve up media images (jpg, png, etc...) on the WordPress blog. S3 uses the term “bucket”, think of it as a container for your files. The bucket name has to be unique across the entire S3 platform.
35. Step 1: Click on the S3 tab and select Create Bucket
36. Step 2: Enter a bucket name
37. Step 3: Click on Upload and upload an image (Use the S3 link when creating a blog post in WordPress)
38. Done. Now What? Make things and break things to learn how all the various services of AWS work together. Visit AWS for more tutorials at: http://aws.amazon.com/articles/

41. Create and edit the config file: cd /var/www/html mv wp-config-sample.php wp-config.php vi wp-config.php Quick VI tutorial – Press i for edit mode. Press Esc on your keyboard after your are done editing. Then type :wq to save the file and quit VI. You will need to edit the following entries in the config file with the values from your RDS MySQL instance: define(‘DB_NAME’, ‘wordpress’); define(‘DB_USER’, ‘root’); define(‘DB_PASSWORD’, ‘YOUR_PASSWORD’); define(‘DB_HOST’, ‘localhost’); Below is a mapping of the WordPress config file and the RDS MySQL instance: ‘DB_NAME’ = Database Name ‘DB_USER’ = Master Username ‘DB_PASSWORD’ = Master User Password ‘DB_HOST’ = Endpoint Instructions to manually edit the WordPress config file
42. From Terminal go to the directory that contains <filename>.pem (the file contains your credentials to access the EC2 instance.) Change the permission of the file: chmod 400 [filename].pem Connect to your EC2 instance: ssh -i [filename].pem ec2-user@[Elastic IP] Switch to superuser: sudo su To install MySQL: yum install mysql-server Start MySQL: service mysqld start Start the service automatically: chkconfig mysqld on Create the wordpress database: mysqladmin -uroot create wordpress Secure your database installation: mysql_secure_installation Instructions to install MySQL on the EC2 instance
