Introduction on Local

To operate PHP Laravel locally, it's essential to have a server environment such as XAMPP, MAMP, or LAMP installed on your machine. Without one of these servers, running a PHP Laravel application on your local device would be impossible. Follow the links below for installation instructions tailored to different operating systems.
You must acquire a web server to execute the application.

• For macOS, obtain MAMP or XAMPP Server.
• For Windows OS, obtain MAMP or XAMPP Server.
• For Linux OS, obtain LAMP or XAMPP Server.
• MAMP Server is available for download at https://www.mamp.info/en/mamp for both Windows and Mac systems.
• XAMPP Server can be downloaded from https://www.apachefriends.org/download.html, supporting Windows, Linux, and Mac operating systems.

PHP Version Requirement

Required PHP version: >= 8.1

To verify the installed PHP version on your server, execute the command below in your terminal or command prompt:

If PHP is not installed, please install the necessary version first.

Required PHP Extensions

• bcmath PHP Extension
• gd PHP Extension
• ctype PHP Extension
• curl PHP Extension
• fileinfo PHP Extension
• json PHP Extension
• mbstring PHP Extension
• OpenSSL PHP Extension
• pcre PHP Extension
• pdo PHP Extension
• tokenizer PHP Extension
• pdo_mysql PHP Extension
• xml PHP Extension
• zip PHP Extension

Composer Installation

Composer is a prerequisite for running Laravel applications. If Composer is not yet installed on your machine, follow the installation instructions for different operating systems below:

• For Mac, initiate Composer installation by clicking here.
• Windows users can complete Composer setup by clicking here.
• For Ubuntu users, learn more about Composer installation and use by clicking here.

Running Laravel on Local

• This guide assumes you have PHP and Composer installed on your system. If not, please refer to the official documentation to install PHP and Composer.

  Step 1: Database Configuration

  First, create a new database for your Laravel application locally. After creating the database, import the gptappdb.sql file in phpmyadmin from the database folder in your downloaded directory.

  

  Open the .env file in your project root and update the database settings accordingly.

  DB_CONNECTION=mysql
  DB_HOST=127.0.0.1
  DB_PORT=3306
  DB_DATABASE=root
  DB_USERNAME=root
  DB_PASSWORD=
  

  Step 2: Serve the Application

  Once the database import is complete, navigate into admin panel folder from your downloaded directory on terminal:

  cd gpt-app-admin-panel

  To start the Laravel development server, run:

  php artisan serve

  This command will start a development server at http://127.0.0.1:8000/en. Open http://127.0.0.1:8000/en/dashboard in your web browser to see your Laravel application. Login with following credentials' info.

  admin@admin.com : password

  For further development and deployment instructions, refer to the official Laravel documentation.

Deploying to Shared Hosting

This guide also applies to other hosting providers.
After downloading the package from the marketplace, you will find a folder named 'gpt-app-admin-panel'. This folder contains the Laravel project.

Deploy to Hostinger

• Prepare Your Laravel Application:
  • Configure the application for production by setting APP_ENV to production and APP_DEBUG to false in your .env file.
  • Run composer (or composer2) install --optimize-autoloader --no-dev to install dependencies without development packages.
  • Execute php artisan config:cache to cache the configuration for faster performance.
• Transfer Files to Shared Hosting:
  • Create a domain or subdomain in your hosting panel:

  

  • Compress your Laravel project into a .zip or .tar.gz archive.
  • Using your shared hosting control panel (e.g., cPanel), navigate to the File Manager.

  

  • Upload the compressed archive to the root or subdirectory.
  • Extract the files.

  

• Database Configuration:
  • Create a new database and user using the cPanel database wizard (or another method).

  

  • After creating the database, import the gptappdb.sql file in phpmyadmin from the database folder in your downloaded directory. Same as local installation.

    

  • Update the .env file with the appropriate database information.

  

  • Connect to your server via SSH and run php artisan config:clear && php artisan route:clear && php artisan cache:clear && php artisan view:clear

  

  

• Update File Permissions:
  • Directories within storage and bootstrap/cache should be writable by the server. You may need to adjust permissions to 755 or 777 (though 755 is generally safer).
• Deploy to Hostinger : https://www.youtube.com/watch?v=zmwdzDWtth0
• Test Your Website:
  Now, visit your website's domain or URL to ensure everything works as expected.
  Our demo admin panel website is https://gptapp.morningstarcode.com/en/dashboard
  admin@admin.com : password

Deploying to Cloud Systems

After downloading the package from the marketplace, you will find a folder named 'gpt-app-admin-panel'. This folder contains the Laravel project.

• AWS Elastic Beanstalk: https://www.honeybadger.io/blog/laravel-php-elastic-beanstalk
  • Install the AWS EB CLI and configure it with 'eb init'.
  • Create a new environment with 'eb create'.
  • Once the environment is set up, deploy your application using 'eb deploy'.
• DigitalOcean + Laravel Forge: https://snapshooter.com/blog/how-to-deploy-laravel-on-digitalocean-with-forge
  • Create a DigitalOcean Droplet.
  • Sign up for Laravel Forge and link it to your DigitalOcean account.
  • Through Forge, create a new server using your Droplet.
  • Once the server is set up, link your Git repository with the Laravel application and deploy from the Forge dashboard.
• Heroku: https://devcenter.heroku.com/articles/getting-started-with-laravel
  • Install the Heroku CLI and run heroku login.
  • Create a new app using heroku create.
  • Add a database if required with Heroku Postgres.
  • Set environment variables using heroku config:set KEY=VALUE.
  • Commit your code and push it to Heroku using git push heroku master.
