create database demoapp;
grant all on demoapp.* to [email protected] identified by 'changeme';

Reload database privilege tables;

flush privileges;
quit

Install Composer PHP Package Manager on Ubuntu 20.04

Assuming you already have the Apache HTTP server, PHP and extensions and Database (MariaDB or MySQL), proceed to install PHP Composer.

Run the script below to install Composer programmatically on Ubuntu;

vim install-composer.sh
#!/bin/sh

EXPECTED_CHECKSUM="$(wget -q -O - https://composer.github.io/installer.sig)"
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
ACTUAL_CHECKSUM="$(php -r "echo hash_file('sha384', 'composer-setup.php');")"

if [ "$EXPECTED_CHECKSUM" != "$ACTUAL_CHECKSUM" ]
then
    >&2 echo 'ERROR: Invalid installer checksum'
    rm composer-setup.php
    exit 1
fi

php composer-setup.php --install-dir=/usr/local/bin --filename=composer --quiet
RESULT=$?
rm composer-setup.php
exit $RESULT

Save and exit the script.

Execute it;

bash install-composer.sh

Check the exit status of the script. It will exit with 1 in case of failure, or 0 on success, and is quiet if no error occurs.

echo $?

Verify composer is installed;

which compoer
/usr/local/bin/composer

You can as well check version of installed composer;

composer --version

Install Laravel PHP Framework On Ubuntu 20.04

If all the prerequisites have been met, proceed to install Laravel PHP framework on Ubuntu 20.04.

There are two ways in which you can install Laravel PHP framework on Ubuntu;

  1. Install Laravel Using Laravel Installer
  2. Install Laravel using Composer
Install Laravel PHP Framework Using Laravel Installer

Create Non root user to run composer as (it is strongly advised to avoid running Composer as super-user/root).

useradd -m -d /var/www/html/laravel -s /usr/bin/bash -g www-data laravel

In the command above, we created a non root user called laravel whose home directory is set to /var/www/html/laravel. We will be using this directory as our default Laravel directory for our Apps.

Switch to the user and run the Laravel live installer as follows;

su - laravel
composer global require laravel/installer
Changed current directory to /var/www/html/laravel/.config/composer
Using version ^4.1 for laravel/installer
./composer.json has been created

All the necessary packages are installed to /var/www/html/laravel/.config/composer directory. As a result, you need to update the PATH environment variable with Laravel binary configuration directory, /var/www/html/laravel/.config/composer/vendor/bin/.

You ca simply run the command below to update the path.

echo 'export PATH="$HOME/.config/composer/vendor/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc
Create PHP demo App using Laravel

laravel new demoapp

Install Laravel PHP Framework using Composer

You can similarly install Laravel PHP framework on Ubuntu using Composer, PHP package manager.

Navigate to the Laravel directory, which in our case is /var/www/html/laravel.

su - laravel
pwd
/var/www/html/laravel

Install Laravel using composer;

composer create-project --prefer-dist laravel/laravel demoapp

Similarly, you can run run php artisan command.

Configure Laravel Application Environment Variables

Once the installation is done, adjust the application environment variables (APP_NAME, APP_ENV, APP_KEY, APP_DEBUG, APP_URL) appropriately;

vim demoapp/.env
APP_NAME=Laravel
APP_ENV=local
APP_KEY=base64:1nzhBMNqoyGP+DYbPM1Pq33MAPTQ+LGpTHwxuADV1v4=
APP_DEBUG=true
APP_URL=http://demoapp.kifarunix-demo.com
...

Define the Laravel application database connection settings as created above;

...
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=demoapp
DB_USERNAME=demoadmin
DB_PASSWORD=changeme
...

Create Apache Site configuration file for Laravel Application

Once you are done with installation and configuration of Laravel, create the specific app Apache site configuration file to enable you access it externally from browser.

The commands below are as root user.

For example, to create Apache site configuration for demoapp Laravel app;

vim /etc/apache2/sites-available/demoapp.conf
<VirtualHost *:80>

        ServerName demoapp.kifarunix-demo.com
        ServerAdmin [email protected]
        DocumentRoot /var/www/html/laravel/demoapp/public

        <Directory /var/www/html/laravel/demoapp>
                Options Indexes MultiViews
                AllowOverride None
                Require all granted
        </Directory>

        ErrorLog /var/log/apache2/demoapp.error.log
        CustomLog /var/log/apache2/demoapp.access.log combined

</VirtualHost>

Save and exit the file and run syntax check;

apachectl -t

Disable the default Apache site;

a2dissite 000-default.conf

Enable demoapp site configuration;

a2ensite demoapp.conf

Set the proper ownership of the demoapp web root directory;

chown -R :www-data /var/www/html/laravel/demoapp/

Restart Apache;

systemctl restart apache2

Accessing Laravel App from Browser

To allow external access to your apps, open HTTP(S) port on firewall if it is running;

ufw allow "Apache Full"

Then navigate to browser and access Laravel App using the URL, http://APP-URL, for example, http://demoapp.kifarunix-demo.com.
