Step 0: Inspect the architecture

• Inspect the example VPC.
• Inspect the subnets.
• Inspect the Security Groups.
• Inspect the AMI.

Step 1: Create a Cloud9 IDE

Step 2: Get the Project Assets

1. Clone the repository:

   git clone https://github.com/baselm/capstoneproject.git
   or 
   wget https://aws-tc-largeobjects.s3-us-west-2.amazonaws.com/ILT-TF-200-ACACAD-20-EN/capstone-project/Example.zip

1. Extract the files to the Apache www folder:

   chown ec2-user Example.zip
   unzip Example.zip -d /var/www/html/

Step 3: Install a LAMP web server on Amazon Linux 2

LAMP (Linux, Apache HTTP server, MySQL database, and PHP) stack
Original tutorial for LAMP Stack Tutorial: Install a LAMP web server on Amazon Linux 2

sudo yum -y update
sudo amazon-linux-extras install -y lamp-mariadb10.2-php7.2 php7.2

sudo yum install -y httpd mariadb-server
sudo systemctl start httpd

sudo systemctl enable httpd
sudo systemctl is-enabled httpd

• Open port 80 from the security group of the Cloud9 EC2 instance
• Get the cloud9 EC2 public instance IP address and test that you can access the website

Step 4: Create a MySQL RDS database instance

with the following specifications.

• Create a db subnet group
• Databasetype: MySQL
• Template: Dev/Test
• DBinstanceidentifier: Example - DB instance size: db.t3.micro
• Storage type: General Purpose (SSD)
• Allocatedstorage: 20GiB - Storageautoscaling: Enabled
• Standbyinstance: Enabled
• Virtualprivatecloud: ExampleVPC
• Databaseauthenticationmethod: Passwordauthentication
• Initialdatabasename: exampledb
• Enhanced monitoring: Disabled

Step 5: Create an Application Load Balancer

• Create target group
• Create an auto scaling group
• Lunch Web Instances in the private subnet

Step 6: Importing the data into the RDS database

_Importing the data into the RDS database instance from CLoud9 or by accessing the web instance via bastion host

1. get the SQLDump file:

2. connect to the RDS database, run this command:
   

mysql -u admin -p --host <rds-endpoint>

1. Test that you can access the RDS DB

 use exampledb; 
show tables; 

1. Import the data into the RDS database.

mysql -u admin -p exampledb --host <rds-endpoint>  < Countrydatadump.sql       

Test the ALB

• Test data was imported

 use exampledb; 
show tables; 
select * from countrydata_final; 

Step 7: Configure the system parameters in Parameter Store Systems Manager

Add the following parameters to the Parameter Store and set the correct values:

1. /example/endpoint

2. /example/username

3. /example/password

4. /example/database exampledb
