How to quickly install and use Laravel? (Tutorial sharing)

Laravel is a very popular PHP web application development framework. Its emergence makes web development more efficient and simpler. In order to develop using the Laravel framework, we need to install Laravel first. The following is a Laravel installation tutorial to help you quickly install and start using Laravel.

1. Confirm the system environment

Before installing Laravel, we need to confirm whether our system environment meets the installation requirements of Laravel. Laravel needs to meet PHP7.2 version and above, and have some necessary PHP extensions installed, including: BCMath, Ctype, JSON, Mbstring, OpenSSL, PDO, Tokenizer, XML.

We can enter the following command on the terminal to check the current PHP version:

php -v

2. Install Composer

Composer is a dependency management tool for PHP , we need to use Composer to install Laravel.

First, let us enter the following command on the terminal to download Composer:

curl -sS https://getcomposer.org/installer | php

Then, we can move the downloaded Composer application to the specified directory (usually /usr/local/ bin):

sudo mv composer.phar /usr/local/bin/composer

Finally, if the installation is successful, we can enter the following command on the terminal and see the version information of Composer:

composer --version

3. Create Laravel project

We need to use Composer to create a Laravel project in the specified directory. First, we need to go to the command prompt into the directory where we want to create the Laravel project. In the specified directory, we can run the following command to create a new Laravel application:

composer create-project --prefer-dist laravel/laravel {project_name}

In {project_name}, we can specify the name of the project we want to create. Waiting for Composer to download and install all Laravel's necessary components and dependencies, our Laravel 5 application will be ready to use.

4. Set Application Key

The Laravel framework uses an application key for encrypting session data and other sensitive data. Before we start using Laravel, we need to generate an application key. Open a terminal from the root directory of the project and run the following command:

php artisan key:generate

This command will automatically generate a random application key and write it to our application's configuration file.

5. Database configuration

In the configuration file of the Laravel project, we need to configure the database connection in order to use the database in the application.

We need to modify the following configuration file:/project_folder/config/database.php.

• We need to configure the database type, host, port, database name, user and password.
• We can also use PHP artisan's command line tool to create database tables. We only need to use the migration command: php artisan migrate.

6. Check Installation

We can verify that Laravel has been successfully installed by accessing the application’s URL (using our web server).

If Laravel is running, we will see a welcome page. This is the home page of the Laravel framework, containing some basic information about Laravel and demo examples.

The above is the installation tutorial of Laravel. I hope this article will be helpful to you. If you encounter any problems or questions, please feel free to leave a message in the comment area so that we can respond promptly and assist you in solving the problem.
