Security Groups

We need to create security groups for instances.

by clicking on Create security group

inbound rules for elb0e-sg (load balancer)

Insert the name.Use pem file if you are not using putty.This is very important to ssh aws instance from our computer.

Launch New EC2 Instances:

  • Navigate to the EC2 Dashboard and click on “Launch instance”.
  • Use the following AMIs for the instances:
  • RabbitMQ (rbmq-01): AlmaLinux 9 AMI
  • Memcache (mc-01): AlmaLinux 9 AMI
  • MySQL (db-01): AlmaLinux 9 AMI
  • Tomcat Application (app-01): Ubuntu AMI
  • Assign the respective security groups created earlier to each instance.
  1. User Data Script:
  • Paste the bash script located in the userdata directory of your repository into the “User data” section of the instance launch wizard.
  • Launch the instances.

Building the Artifacts

https://miro.medium.com/v2/resize:fit:250/1*BLMRxVhEhC6fLPIioQulcw.png

To build the artifact it is important to have JDK and Maven installed in your PC

https://miro.medium.com/v2/resize:fit:875/1*NwX0u-tGYjea_gnMrjID2A.png

  1. Setup Development Environment:
  • Ensure JDK and Maven are installed on your local machine.
  • Configure Application Properties:
  • Edit the application.properties file, changing digitalsierra.in to <yourdomainname.xyz>.
  1. Build the Artifact:
  • Run the following command to build the artifact:
  • mvn install
  1. Upload Artifact to S3:
  • Install the AWS CLI on your local machine.
  • Create a new IAM user in the AWS Management Console and obtain the access key and secret key.
  • Configure the AWS CLI with the obtained credentials:
  • Copy code
  • aws configure
  • Create a new S3 bucket:
  • sh
  • Copy code
  • aws s3 mb s3://<bucket-name>

Copy the build artifact to the S3 bucket:

  • aws s3 cp target/vprofile-v2.war s3://<bucket-name>

Create an user and get access and secret key

https://miro.medium.com/v2/resize:fit:875/1*-qTSLN9PfdfYtaNMLpSc3g.png

Use aws configure to configure cli

Now from your computer create an bucket using aws s3 mb s3://

then copy the vprofile-v2.war to the bucket use cp /target/vprofile-v2.war aws s3 mb s3://

https://miro.medium.com/v2/resize:fit:70/1*BUN46e-sD9oJdXtM0DGy2w.png

Now access the App-01 ubuntu instance

and remove from tomcat9/webapps using this rm-rf tomcat9/webapps/ROOT.war

Copy aws s3:///vprofile-v2.war to tomcat9/webapps/ROOT.war

Now lets Hop On to

Load Balancer and DNS

https://miro.medium.com/v2/resize:fit:875/1*6Nuo7N9KPDVkAmgG3Qmy-w.png

Create a new target group it falls under load balancing in EC2

https://miro.medium.com/v2/resize:fit:875/1*C1tjoyhmCJTJo6sWcCP47w.png

Use round robin

https://miro.medium.com/v2/resize:fit:875/1*9_XFqOlvQ5KpegCbE4AnBw.png

Unified configuration and create.

https://miro.medium.com/v2/resize:fit:875/1*lJxqlWMH-B_Q3g7B0gLf2w.png

Use Application Load balancer

check all mappings use HTTP port 80 And use the above target group

https://miro.medium.com/v2/resize:fit:875/1*H5pb_nNw7kaXOJbxO4L8bQ.png

If you have you have acm certificate you can add https port 443

https://miro.medium.com/v2/resize:fit:875/1*2WCRhL5BZP9PzIdqfW7GOA.png

Use DNS Name to access application

https://miro.medium.com/v2/resize:fit:875/1*StnsB2IqXJcxAUxdoz7C7g.png

You can see login using admin_vp:admin_vp
