How to install Magento 2.4.3 on Ubuntu 20.04 with LAMP

Magento is a open source e-commerce platform written in PHP. And it is highly popular ecommerce platform and owned and managed by Adobe Inc. The platform is flexible and has a large variety of features to build an online store.

In this tutorial we will guide you on how to install Magento 2.4.3 using the LAMP stack.

Let us start the installation.

1. Updating the system

sudo apt update -y && apt upgrade -y

2. Installing PHP and PHP extensions

The default PHP version of Ubuntu 20.04 is PHP 7.4. In this setup we will use PHP 7.4 since it is the required version for the 2.4.3 version. Let us proceed installing PHP and the extensions.

sudo apt install php libapache2-mod-php php-bcmath php-curl php-fpm php-gd php-intl php-mbstring php-mysql php-soap php-xml php-xsl php-zip php-cli

Let us modify some of the PHP values to meet the requirements.

Find the PHP configuration file.

root@techtutorguro:~# php --ini | grep "Loaded Configuration File"
Loaded Configuration File:         /etc/php/7.4/cli/php.ini

Open the configuration file using your favorite editor.

nano /etc/php/7.4/cli/php.ini

Modify the configuration file with the values below.

 memory_limit = 1G
 upload_max_filesize = 128M
 zlib.output_compression = on
 max_execution_time = 18000
 realpath_cache_size = 10M
 realpath_cache_ttl = 7200

Then save the configuration file.

3. Database Installation and configuration

The database that we are going to use in this tutorial is MariaDB.

Let us proceed with the Database installation.

sudo apt install mariadb-server -y

Let us configure MariaDB server.

sudo mysql_secure_installation

Output:

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none): Press Enter

You already have a root password set, so you can safely answer 'n'.

Change the root password? [Y/n] n

Remove anonymous users? [Y/n] Y

Disallow root login remotely? [Y/n] Y

Remove test database and access to it? [Y/n] Y

Reload privilege tables now? [Y/n] Y

Restart MariaDB service:

sudo systemctl restart mariadb

Let us create the database for our application.

First login to our MariaDB console.

sudo mysql -u root

Now create the Database name and Database user.

MariaDB [(none)]> create database magento2;
MariaDB [(none)]> grant all privileges on magento2.* to 'magento_user'@'localhost' identified by 'mypassword';
MariaDB [(none)]> flush privileges;
MariaDB [(none)]> exit;

Please don’t forget to change the “mypassword” to your desired password.

4. Web server Installation and Configuration

Since this tutorial is on LAMP stack we will install Apache web server.

sudo apt install apache2

Let us start and enable Apache web server.

sudo systemctl start apache2

sudo systemctl enable apache2

Create a Virtual Host for our site.

nano /etc/apache2/sites-available/domain.com.conf

Add below content.

<VirtualHost *:80>
  
        ServerAdmin webmaster@localhost

        ServerName domain.com
        ServerAlias www.domain.com
        DocumentRoot /var/www/magento2/pub
  
        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
  
        <Directory "/var/www/">
                    AllowOverride all
        </Directory>
</VirtualHost>

Please note to change the ServerName and ServerAlias to your own domain.

Let us enable the Virtual Host

a2ensite domain.com.conf

Then enable mod_rewrite module.

a2enmod rewrite

Restart Apache for the configuration to take effect.

systemctl restart apache2

5. Installing Elastic Search

Starting the 2.4 version, all installations must be configured to use Elasticsearch.

Before we proceed with the Elasticsearch installation we need to install the required dependencies.

sudo apt install apt-transport-https ca-certificates gnupg2

Import the GPG key.

wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -

Add the Elasticsearch repository.

sudo sh -c 'echo "deb https://artifacts.elastic.co/packages/7.x/apt stable main" > /etc/apt/sources.list.d/elastic-7.x.list'

Let us now install Elasticsearch.

sudo apt update

sudo apt install elasticsearch

Then start and enable the service.

systemctl start elasticsearch

systemctl enable elasticsearch

6. Installing Composer

Composer is used to manage PHP packages.

Let us proceed in installing composer.

curl -sS https://getcomposer.org/installer -o composer-setup.php

sudo php -d memory_limit=-1 composer-setup.php --install-dir=/usr/local/bin --filename=composer

NOTE: If you encounter “PHP Fatal error: Allowed memory size exhausted” in running composer better to set your PHP memory_limit value to -1 or unlimited.

7. Download and Install Magento 2.4.3

For most situation it is recommended to install it using the Marketplace by creating access key.

Let us create an access key.

• First Login to your Marketplace account

• Go to Name->My Profile

• Go to Marketplace->My Products->Access Keys

• Under Magento 2 tab click “Create A New Access Key“

• On the popup enter any name in textbox then click OK.

• You’re done and you will see the Access Keys generated.

Now Let us proceed with the Installation.

First run this command.

composer create-project --repository-url=https://repo.magento.com/ magento/project-community-edition=2.4.3 /var/www/magento2

After running the command above it will ask you to provide the username and password which is your Access keys.

Username: YOUR_PUBLIC_KEY
Password: YOUR_PRIVATE_KEY

After entering the credentials the installation will ask you if you want to store the credentials in ” /root/.config/composer/auth.json ” just select Y.

Do you want to store credentials for repo.magento.com in /root/.config/composer/auth.json ? [Yn] Y

Go to your Magento root directory.

cd /var/www/magento2

Let us now proceed with the installation.

Note: Please don’t forget to modify the values below based on your own set of values.

bin/magento setup:install \
--base-url=http://domain.com \
--db-host=localhost \
--db-name=magento2 \
--db-user=magento_user \
--db-password=mypassword \
--admin-firstname=admin \
--admin-lastname=admin \
[email protected] \
--admin-user=admin \
--admin-password=myadminpassword \
--language=en_US \
--currency=USD \
--timezone=America/Chicago \
--use-rewrites=1

After the installation process you will see the admin link for your site.

[SUCCESS]: Magento installation complete.
[SUCCESS]: Magento Admin URI: /admin_5shsgt

NOTE: If your database password contains special characters(!@#$%^$*) you will encounter issue like this:

SQLSTATE[HY000] [1045] Access denied for user ‘user’@’localhost’

SOLUTIONS: add backslash before the special characters.

If your database password is something like this “myp@55w0rd“ your database password should be set below:

–db-password= myp\@55w0rd

8. Setup the Cron Jobs

Cron jobs is used to automate important operation. Let us setup the cron jobs.

sudo bin/magento cron:install

Before we access our instance we need to fix the permission.

sudo chown -R www-data:www-data /var/www/magento2

That’s it you can now access your Magento site but if you encounter issue logging in to your site you need to disable the Two factor authentication, to that run the following command.

sudo bin/magento module:disable Magento_TwoFactorAuth

Congratulations you have successfully installed Magento 2.4.3  you can now access your site at http://domain.com
