Installing Magento 2 using Composer is the most efficient way to set up your store, ensuring smooth updates and dependency management. Composer helps you manage Magento 2 modules, extensions, and core files effortlessly. This method allows you to install the latest Magento 2 version while maintaining security and stability. Before you begin, ensure your server meets Magento 2 system requirements. You'll need SSH access, PHP, MySQL, and Composer installed.
Installing Magento 2 via Composer is the recommended method because it ensures efficient dependency management, streamlined updates, and better security. With just a few commands, you can download and configure Magento 2 quickly. This blog will guide you through the advantages of installing Magento 2 using Composer, the step-by-step installation process for versions 2.4.5, 2.4.6, and 2.4.7, and troubleshooting tips to resolve common issues.
Updating Magento 2 and its dependencies is simpler with Composer. Instead of manually replacing files, you can run a single command to update Magento core, extensions, and required libraries, ensuring your store always runs on the latest stable version.
Composer automatically manages all required Magento 2 packages and dependencies. It ensures that libraries, extensions, and core files are correctly installed and up to date, reducing compatibility issues and preventing conflicts between different software components.
Composer seamlessly integrates with version control systems like Git, making it easier to track changes, roll back updates, and collaborate on projects. This ensures a structured development process and minimizes risks when modifying or updating Magento 2.
Composer fetches Magento 2 packages directly from official and trusted sources, ensuring that only verified and compatible modules are installed. This reduces the risk of malware, vulnerabilities, and unauthorized modifications, keeping your store secure.
By managing dependencies effectively, Composer minimizes file conflicts and unnecessary downloads. It only installs essential components, reducing storage usage and making the Magento 2 setup more efficient and streamlined.
Developers can easily install, update, and manage third-party extensions using Composer. This allows seamless integration of custom modules without manually copying files, improving flexibility and reducing potential issues during the installation process.
Optimized dependency management ensures that Magento 2 operates efficiently, leading to faster load times and smoother updates. By keeping unnecessary code and outdated libraries out of the system, Composer enhances overall store performance and stability.
Magento requires a MySQL database. You can create one using the following command:
CREATE DATABASE magento2;
GRANT ALL ON magento2.* TO 'magento_user'@'localhost' IDENTIFIED BY 'your_password';
FLUSH PRIVILEGES;
Magento 2 requires specific PHP extensions. Ensure you have the following installed:
sudo apt install php php-cli php-curl php-xml php-mbstring php-bcmath php-intl php-soap php-mysql php-xsl php-zip unzip -y
Elasticsearch is mandatory for Magento 2.4 and later versions. Install it using the following steps:

tar -xvzf elasticsearch-7.17.0-linux-x86_64.tar.gz
cd elasticsearch-7.17.0
./bin/elasticsearch &
Enable Elasticsearch to start on boot:
systemctl enable elasticsearch
systemctl start elasticsearch
Verify that Elasticsearch is running:
curl -X GET "localhost:9200/"
Modify the Elasticsearch configuration file (/etc/elasticsearch/elasticsearch.yml) if needed, then restart the service.
Download and install Composer globally:
curl -sS https://getcomposer.org/installer | php
mv composer.phar /usr/local/bin/composer
Verify the installation:
composer -v
