How to Install Magento 2 via Composer

This method to install Magento is a bit complicated and time-consuming. We will try to cover every possible detail to install Magento using composer successfully.

Step 1: Install Magento Composer

1. Open the terminal or command prompt and run the following command to check if Magento composer has already been installed:

composer –help
composer list –help

2. If nothing displays or any error, please install the Magento composer:

Create an empty directory on your server or system directory to install Magento 2 with composer and run the following commands:

curl -sS http://getcomposer.org/installer | php
mv composer.phar /usr/localhost/bin/composer

You have successfully installed Magento composer in the directory /usr/localhost/bin/composer.

For Windows:
You can also manually download the composer from Getcomposer site.

3. After this, check the Composer version with the following command:

composer -v

Please Note: If you face any technical issues, please free to ask and for more information, please refer Magento official documentation.

Step 2: Login As a File System Owner

1. Access the directory and folder in which you want to install Magento 2 i.e., public_html or var/www/html/magento2. Note if you are login into the Magento server, change the server directory file system owner to a user with permissions to write the Magento file system.

2. Add <magento_root>/bin to your system PATH to run Magento commands from any directory.

export PATH=$PATH:/var/www/html/magento2/bin

Optionally, you can run the commands in the following ways:

cd <magento_root>/bin and run them as ./magento <command name>
<magento_root>/bin/magento <command name>
<magento_root> is a subdirectory of your web server docroot.

Please follow the instructions further to download the Magento Meta package

Step 3: Download Magento

You can download Magento 2 version directly from its official website

OR

Run a command using composer to download specific Magento 2 version

Command:

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

Magento Open Source

composer create-project --repository-url=https://repo.magento.com/ 
magento/project-community-edition:2.4.5

Adobe Commerce (Enterprise)

composer create-project --repository-url=https://repo.magento.com/ 
magento/project-enterprise-edition:2.4.5

In magento installation by the above command you can specify the specific version of Magento (2.0, 2.1, 2.2.1, 2.2.2, 2.2.3, 2.2.4, 2.2.5, 2.2.6, 2.3, 2.4).

Note: To install Magento 2 using composer in the current directory (e.g., public_html), do not forget to add the (.) dot at the end.

During this process, before downloading Magento, you would be asked to Insert your repo.magento.com username and password. For repo.magento.com username and password, log in to Magento Marketplace and select My Account from the top-right corner. Now click Access Keys and Generate your new SECURE KEYS.

• Public Key: Is your username
• Private Key: Is your password

After inserting your repo.magento.com username and password, it will ask for store credentials. Type “Yes.”

Then Magento 2 will now start downloading on your server.

Step 4: Set Permission to Install Magento 2.4

To install Magento 2, you now need to set proper permissions for your Magento 2 Store. Magento has a set of recommended permissions which we have to apply.

a ) The owner must have full access to files.

b ) Web Server must have write permission on var, app/etc and pub directory.

c ) Execute permission of bin/magento.

Some permissions command need to be run for it

Command:

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

Step 5: Create Database for Magento installation

Create and empty database with MySQL/MariaDB

Command:

echo "CREATE DATABASE magento2" | mysql -u[mysqluser] -p

Step 6: Install Magento 2.4

Now, the install Magento command needs to be executed

Command:

php bin/magento setup:install --base-url="http://phpstack-739336-2511019.cloudwaysapps.com/" 
--db-host="167.99.205.158" 
--db-name="magento2" 
--db-user="yrzhqayjyq" 
--db-password="VA2r8RdxAe" 
--admin-firstname="Admin" 
--admin-lastname="Admin" 
--admin-email="[email protected]" 
--admin-user="admin" 
--admin-password="Testing123%567" 
--use-rewrites="1" 
--backend-frontname="admin" 
--db-prefix=mage_

The above command ensures that base-url is “http://yoururl/cloudways.com” your application url, db-host is the hostname or IP address of the server, db-name is the name of database, db-user is the username of the database and db-password is the password of your database. You can customize the admin’s first name, last name, and other parameters.

Note: This command is executed with dummy data. You need to fill in this information based on your application information.
