It can be done via Composer, the Git repository, and manual installation. The article will follow and drive you through the standard process via composer and the prerequisite of the software requirements.

Magento 2 Installation via Composer¶

Benefits¶

Using Composer to install Magento metapackage and manage Magento components and their dependencies provide listed benefits:

• One can reuse third-party libraries without bundling them with source code.
• With the robust dependence of a component-based architecture, extension conflicts and compatibility issues get reduced.
• Stick to PHP-Framework Interoperability Group (FIG) standards
• Repackage Magento Open Source with other components
• You can use Magento in a production environment

Having said this, let’s find out the software prerequisites before installation.

System Requirements¶

Listed are the requirements to match the software download before starting the process.

• Web Server: Apache 2.4
• MySql version: 8.0
• PHP version: 8.1
• Composer: 2.X

There are detailed system requirements, including elastic-search, open-search, cache components, etc., available here for each Magento version. Before starting the process, ensure system requirements, install Composer and get the authentication keys to the Magento composer repository.

Installation Process¶

1. Log in as a user to your Magento server to get the ownership and allow permission to access the source to other users. Find more on the user and approvals here.

2. Change the configured directory from the virtual host docroot to the web server docroot directory or a directory.

3. Change the virtual host docroot directory to server docroot or a directory.

   1. Using Magento Open Source or Adobe Commerce metapackage, create a new composer project.

      Magento Open Source

      1	composer create-project --repository-url=https://repo.magento.com/ magento/project-community-edition <install-directory-name> 2

      Adobe Commerce

      1	composer create-project --repository-url=https://repo.magento.com/ magento/project-enterprise-edition <install-directory-name> 2

      Enter your Magento authentication keys ( Public and Private) that are created and configured in your Commerce Marketplace.

   2. If the Magento installation is done for decent scenarios, say Minor release, Quality patch, or security patch follow the command as given below:

      1. Minore Release: This release contains feature updates, security fixes, and quality fixes. To specify the installation for such a release metapackage for Adobe Commerce 2.4.3, use this:

         1	composer create-project --repository-url=https://repo.magento.com/ magento/project-enterprise-edition=2.4.3 <install-directory-name> 2

      2. Security Patch: This release is related to security fixes only. To specify the installation for Adobe Commerce 2.4.3, use this:

         1	composer create-project --repository-url=https://repo.magento.com/ magento/project-enterprise-edition=2.4.3 <install-directory-name> 2

      3. Quality Patch: This release contains functional and security fixes and sometimes contains additional features. To specify the installation for Adobe Commerce 2.4.3, use this:

         1	composer create-project --repository-url=https://repo.magento.com/ magento/project-enterprise-edition=2.4.3-p1 <install-directory-name> 2

4. Set read-write permissions for the web server group before installing the Magento. This is necessary to allow the command line to write files to the Magento file system.

Now you have successfully installed Magento software, and you can have a black theme, so this might lead you to think about how you can find the same data? Let’s roll out and see how you can add sample data to see the native functionality!

Install Sample Data¶

As the article focuses on the installation via composer, let us see how you can install the sample data. You need to enter the following command as a file system owner in the <magento_root> folder:

1

bin/magento sampledata:deploy

If you install sample data after Magento installation, make sure to update the database schema in the root folder.

1

bin/magento setup:upgrade

Once you are done with the given command, you need to authenticate it. Sometimes you may find the authentication error as displayed:

1
2
3

[Composer\Downloader\TransportException]
The 'https://repo.magento.com/packages.json' URL required authentication.
You must be using the interactive console to authenticate

Change the Magento directory and run composer update , which will prompt you for the authentication keys.

Once you download the sample data packages, log in to your Magento server as the file system owner and the follow command in <magento_root> folder:

1

bin/magento setup:upgrade
