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

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

sudo systemctl enable httpd
sudo systemctl is-enabled httpd
Enter fullscreen mode Exit fullscreen mode
  • 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>
Enter fullscreen mode Exit fullscreen mode
  1. Test that you can access the RDS DB 
 use exampledb; 
show tables;
Enter fullscreen mode Exit fullscreen mode
  1. Import the data into the RDS database. 
mysql -u admin -p exampledb --host <rds-endpoint>  < Countrydatadump.sql
Enter fullscreen mode Exit fullscreen mode

Test the ALB

  • Test data was imported 
 use exampledb; 
show tables; 
select * from countrydata_final;
Enter fullscreen mode Exit fullscreen mode

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

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