Configure Load Balancing

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.

What You'll Build

• Dedicated MySQL server for better performance
• Bagisto on multiple EC2 instances behind a Load Balancer
• Amazon S3 for storage instead of local file storage
• AMI to easily scale new instances
• Application Load Balancer (ALB) for traffic distribution
• 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 update the system:

sudo 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

S3 Bucket Configuration for Bagisto

Create S3 Bucket

Follow the documentation S3 Bucket and Policy Setup for Bagisto to create an 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

Follow the steps from the Bagisto setup guide on AWS but skip step 7 (Install MySQL Server) as it is already done in the dedicated DB server.

Use the latest composer commands.

Configure Bagisto Database Connection

Use the following database details:

Database Configuration

DB_HOST=<public IP of dedicated DB server>
DB_DATABASE=bagistodb
DB_USERNAME=bagistouser
DB_PASSWORD=<your-db-password>

Manual Configuration

// If configuring manually
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.

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.

Register Instances in the Target Group

Choose the instances to be added to the 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)

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.

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:

• S3 integration is working
• Application can connect to the MySQL database
• All features are functional

Success

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.
