How to Install Magento 2 Composer
Embarking on your journey to install Magento 2 Composer is a smart move towards a more efficient and streamlined setup. Here’s a detailed guide to walk you through the process step by step.
Step 1: Install Composer via Command Line or Download
First, let’s delve into understanding what Composer is:
Composer is a highly-regarded open-source dependency management tool specifically designed for PHP. It aids users in developing projects within a given framework. Composer facilitates the installation of third-party libraries and can be implemented via the command line or a direct download link. Here’s how to get started:
Install Composer via Command Line
Check Existing Installation:
Begin by checking if Composer is already installed on your system. Run the following commands in your terminal:
composer --help
composer list --help
If these commands return information about Composer commands, then it’s already installed. If nothing displays or you encounter errors, proceed to install Composer. To install Composer, first, download the installation script. In your terminal, run:
curl -sS https://getcomposer.org/installer | phpThis command downloads the Composer installation file (composer.phar) and saves it in the current directory.
To use Composer globally (from any directory), move the composer.phar file to a directory included in your system’s $PATH variable. A common global directory is /usr/local/bin/. Run:
mv composer.phar /usr/local/bin/composer
This command relocates the composer.phar to /usr/local/bin/ and renames it to ‘composer’, making it globally accessible.
Finally, confirm that Composer has been installed correctly. In your terminal, type:
composer --versionThis should display the installed version of Composer, indicating a successful installation.
Install Composer via Download Link
Start by navigating to the official Composer website at https://getcomposer.org/download/. Here, you’ll find the Composer installation file tailored to different operating systems. Select and download the appropriate version for your system.
After the download is complete, you need to move the downloaded file into a directory that’s included in your system’s $PATH variable. If you’re on macOS, for example, a common path to move the file would be /usr/local/bin/.
Next, you’ll need to rename the file to composer, making it easier to execute. By default, the downloaded file is named composer.phar. To rename it, run the command:
mv composer.phar composerThis command removes the .phar extension, simplifying the command you’ll use to invoke Composer.
The final step is to ensure that Composer has been installed correctly. You can verify this by checking its version. In your terminal, execute the command:
composer --versionCongratulations! You have now successfully installed Composer using a download link. You’re all set to manage dependencies for your PHP applications more efficiently.
If you encounter any technical issues during the installation process, don’t hesitate to ask our Magento specialists for help. For more detailed information and advanced topics, refer to Magento’s official documentation. Your journey on how to install Magento 2 using Composer is just beginning, and a world of efficient PHP dependency management awaits.
Step 2: Access as the File System Owner
Before beginning the installation of Magento 2, ensure you’re accessing the directory where Magento will be installed, like public_html or var/www/html/magento2. If you’re logged into the Magento server, verify that you’re operating as the file system owner, who should have write permissions for the Magento file system.
To facilitate running Magento commands from any location, add <magento_root>/bin to your system’s PATH with the command:
export PATH=$PATH:/var/www/html/magento2/binAlternatively, you can directly navigate to <magento_root>/bin and execute commands using ./magento <command name>, or you can run them from any directory using the full path <magento_root>/bin/magento <command name>. Here, <magento_root> is the subdirectory under your web server’s document root.
Step 3: Download Magento 2
Installing Magento 2 can be accomplished directly from its official website or you can install Magento 2 via Composer to download a specific version. Here’s how you can proceed:
To install the community edition of Magento 2, use the following command:
composer create-project --repository-url=https://repo.magento.com/ magento/project-community-edition <install-directory-name>For Magento Open Source specify the version you need, like this:
composer create-project --repository-url=https://repo.magento.com/
magento/project-community-edition:2.4.6
For Adobe Commerce (Enterprise), to install Magento 2 enterprise Composer, specify the version you need, like this:
composer create-project --repository-url=https://repo.magento.com/ magento/project-enterprise-edition:2.4.6
During the Magento installation, you have the flexibility to select a specific version (ranging from 2.0 to 2.4) using the above commands. Remember, if you’re installing Magento 2 in the current directory, such as public_html, add a dot (.) at the end of the command.
Before the download commences, you’ll need to provide your repo.magento.com username and password. To obtain these, log into Adobe Marketplace, go to My Account at the top-right corner, and then click Access Keys to generate your new secure keys. Your public key will serve as your username, and the private key will be your password.
Once you enter your repo.magento.com credentials, you’ll be prompted for store credentials. Type Yes to proceed.
After these steps, Magento 2 will begin downloading onto your server.
Step 4: Set Up Permissions
Once you’ve downloaded Magento 2, the next crucial step is setting the appropriate permissions for your Magento 2 Store. Magento comes with a set of recommended permissions to ensure the smooth operation and security of your store. Here’s what you need to do:
The owner of the files should have full access. This is crucial for managing and updating files within your Magento installation.
The web server must have to write permissions specifically on the var, app/etc, and pub directories. These are essential for Magento’s operation, allowing it to store sessions, cache, and various configuration settings.
Ensure that the bin/magento has execute permission. This is necessary to run Magento CLI commands.
At this stage, you need to execute certain commands to set these permissions. Here are the commands you’ll use:
find . -type f -exec chmod 644 {} \;
find . -type d -exec chmod 755 {} \;
chmod -Rf 777 var
chmod -Rf 777 pub/static
chmod -Rf 777 pub/media
chmod 777 ./app/etc
chmod 644 ./app/etc/*.xml
chmod -Rf 775 bin
By correctly setting these permissions, you’ll provide a secure and functional environment for your Magento 2 store to operate in.
Step 5: Create a Database
For Magento 2 to store its data, you’ll need to create an empty database in MySQL. This is a critical step in setting up your environment for Magento’s installation.
To create the database, simply run the following command in your terminal:
echo "CREATE DATABASE magento2" | mysql -u[mysqluser] -p
Replace [mysqluser] with your actual MySQL username. You’ll be prompted to enter your MySQL password. Once done, a new database named magento2 will be created, ready for Magento’s installation and use.
Step 6: Install Magento 2.4
With the permissions correctly set and your database ready, you’re now poised to initiate the Magento 2 installation process. This crucial step will configure Magento with your server and set up the administrative credentials.
To install Magento 2 Composer, navigate to the Magento 2 root directory in your command line and execute the following commands:
php bin/magento setup:install \
--base-url="http://yoururl.com/" \
--db-host="localhost" \
--db-name="dbname" \
--db-user="dbuser" \
--db-password="dbpass" \
--admin-firstname="admin" \
--admin-lastname="adminx" \
--admin-email="user@test.com" \
--admin-user="admin" \
--admin-password="admin123" \
--language="en_US" \
--currency="USD" \
--timezone="America/Chicago" \
--use-rewrites="1" \
--backend-frontname="admin"
Please ensure to replace the placeholder values (like http://yoururl.com/, dbname, dbuser, dbpass, etc.) with the actual details specific to your setup. These include your site’s URL, database name, user, password, and preferred admin credentials among others.
Upon successful execution of these commands, you will receive a notification informing you that the installation has been completed. You’re now ready to explore and enjoy the extensive features and capabilities of your new Magento 2.4 platform.
Step 7: Check the New Magento 2 Application
Once you successfully install Magento 2 using Composer on your server, it’s time to see the fruits of your labor. You should be able to view both the Frontend and Backend of your Magento 2 application.
Initially, you won’t see much content. To populate your store with sample data and get a real feel for how your site will look and operate, execute the following commands:
First, deploy the sample data:
php bin/magento sampledata:deployNext, enable all the modules:
php bin/magento module:enable --allFinally, upgrade the setup to reflect the changes:
php bin/magento setup:upgradeAfter running these commands, visit your Magento 2 Frontend; it should now display the sample data, giving you a more realistic view of your store. Additionally, access the admin login page to explore the Backend and start customizing your new eCommerce platform.
