The following diagram provides a high-level overview of on-premises installations of Adobe Commerce and Magento Open Source:
The general installation flow is as follows:
Set up your server environment.
Install the prerequisite software, including PHP, Apache, MySQL, and the search engine. See the system requirements for more information.
Get authentication keys to the Commerce Composer repository.
Get the Adobe Commerce or Magento Open Source software.
(Recommended) Get the Composer metapackage to manage modules and their dependencies.
If you want to contribute to the Magento Open Source codebase or customize the application, clone the GitHub repository. This method requires familiarity with both GitHub and Composer.
Install the application using the command line.
If the step fails because prerequisite software isn’t set up correctly, review the prerequisites.
Verify the installation by viewing your storefront and the Admin.
