# Load Balancing

# Introduction

This guide provides a step-by-step approach to deploying Bagisto on AWS with an Application Load Balancer (ALB) for improved scalability and high availability. By setting up a dedicated database server, integrating Amazon S3 for media storage, and configuring an AMI-based auto-scaling setup, you can ensure that Bagisto can handle increased traffic efficiently.

The process includes:

  • Setting up a dedicated MySQL server for better performance.
  • Deploying Bagisto on multiple EC2 instances behind a Load Balancer.
  • Using Amazon S3 for storage instead of local file storage.
  • Creating an AMI to easily scale new instances.
  • Configuring an Application Load Balancer (ALB) for traffic distribution.
  • Setting up SSL and domain configuration for secure access.
  • This setup ensures a scalable, fault-tolerant, and high-performance Bagisto application. 🚀

# Bagisto with ALB Setup on AWS

# Dedicated Database Server Setup

# Launch EC2 Instance for MySQL Database

  • Launch an EC2 instance for MySQL database.
  • Assign an Elastic IP to the EC2 instance.

# install and Configure MySQL Server

  • SSH into the EC2 instance and run apt-get update.
  • Install MySQL server:
sudo apt-get install mysql-server
  • Secure the MySQL installation and create the database:
sudo mysql -u root -p
CREATE DATABASE bagistodb;
CREATE USER 'bagistouser'@'localhost' IDENTIFIED BY '<your-db-password>';
GRANT ALL ON bagistodb.* TO 'bagistouser'@'localhost' WITH GRANT OPTION;
SET GLOBAL log_bin_trust_function_creators = 1;
FLUSH PRIVILEGES;
EXIT;

# Update MySQL Bind Address

  • Modify the bind address from 127.0.0.1 to 0.0.0.0 in /etc/mysql/mysql.conf.d/mysqld.cnf.

# Restart MySQL Server

  • Restart the MySQL service:
sudo systemctl restart mysql

# Open MySQL Port (3306) in Security Group

  • Modify the security group for this EC2 instance to allow inbound traffic on port 3306.

# Verify Database Connectivity

  • Test connectivity using telnet <EC2-ip> 3306 from your system

# S3 Bucket Configuration for Bagisto

# Create S3 Bucket

# Configure IAM Role for S3 Access

  • Create an IAM role with the required permissions to allow Bagisto to interact with S3. Use the Access Key ID, Secret Key, Bucket Name, Region, and Bucket URL.

# Bagisto Server Setup

# Launch EC2 Instance for Bagisto Application

  • Launch a new EC2 instance for the Bagisto application.

# Install MySQL Client

  • SSH into the EC2 instance and install the MySQL client:
sudo apt-get install mysql-client-8.0

# Install Bagisto

# Configure Bagisto Database Connection

  • Use the following database details:
    • Host: <public IP of dedicated DB server>
    • User: bagistouser
    • Dbname: bagistodb
    • Password: <your-db-password>

# Install S3 Integration Module

  • Install and configure the S3 module for Bagisto using the IAM credentials.

# Access Bagisto Admin Panel

  • Visit the admin panel at: http://<this-ec2-public-ip>/admin to complete configurations.

# Create AMI for Bagisto Application

# Create AMI from Bagisto EC2 Instance

  • Go to Instances > Actions > Image and templates > Create Image.

Create Image

  • Enter the image name and click Create Image.

# Wait for AMI to Be Available

  • Monitor the status of the AMI in the AMI section.

# Launch Instances from AMI

  • Once the AMI is available, go to AMIs and launch as many instances as required in the target group.

# Configure Target Group

# Create Target Group

  • Go to Target Groups and click Create Target Group.
  • Choose Instances as the target type and give it a name.

Target Group

# Register Instances in the Target Group

  • Choose the instances to be added to the target group

Create Target Group

# Configure Load Balancing Algorithm

  • After creating the target group, go to Attributes and choose the desired load-balancing algorithm (default: round-robin). Enable stickiness.

# Create and Configure Application Load Balancer (ALB)

# Create ALB

  • Go to Load Balancers and click Create Load Balancer.

  • Choose Application Load Balancer and provide the following configurations:

    • Internet-facing.
    • Select all Availability Zones.
    • Choose the target group created earlier and configure the listener on port 80 (HTTP).

Create Load Balancer

# Adjust Security Groups

  • Modify the security groups to allow necessary traffic (e.g., HTTP/HTTPS).

# Verify Load Balancer Configuration

  • Copy the DNS name of the load balancer and verify it.
  • Configure the domain name (CNAME) to point to this load balancer DNS for production use.

# Set Up SSL on Load Balancer

  • Configure the ALB listener to use HTTPS (port 443), ensuring that an SSL certificate is installed.

Load Balancer Result

# Verify and Test the Entire Setup

# Test Load Balancer

  • Confirm that the load balancer is distributing traffic across the registered instances.

# Verify Domain Configuration

  • Ensure the domain is resolving correctly to the load balancer.

# Test Bagisto Functionality

  • Access the Bagisto application and verify that the S3 integration is working, the application can connect to the MySQL database, and all features are functional.

Bagisto with ALB Setup on AWS is Successfully Configured!

The Bagisto application is now running behind an Application Load Balancer (ALB) with a dedicated MySQL database and S3 integration for storage. The load balancer is efficiently distributing traffic across multiple instances, ensuring high availability and scalability.
