Detailed explanation of how to quickly install and configure Laravel

Laravel is a popular PHP framework that provides an easy-to-use, efficient and stable development platform. If you are learning or using Laravel, you may encounter some configuration issues. This article will introduce how to set up Laravel to help you get started quickly and avoid some common mistakes.

1. Install Composer

Composer is a dependency management tool for Laravel, we need to install it first. Composer can be downloaded and installed by visiting getcomposer.org. After the installation is complete, use the following command to verify whether Composer is installed successfully.

composer --version

2. Installing Laravel

Before installing Laravel, you need to make sure that PHP and web server have been installed. Laravel officially recommends using PHP version 7.1 or higher. We can install the latest version of Laravel with the following command.

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

Where, myproject is the name of the Laravel project you want to create. This command will create a new Laravel project in your current working directory.

3. Configuring the database

Laravel uses MySQL as the database by default, and we need to set the database connection information. Open the .env file in the project directory and modify the following options in it.

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

HereDB_DATABASE option is the database name you want to use, DB_USERNAME and DB_PASSWORD options are your database username and password.

4. Set Application Key

Laravel uses application keys to protect sensitive data such as cookies and sessions. Open the .env file and find the following options.

APP_KEY=

Laravel officially provides a command to generate application keys. Run the following command in the terminal.

php artisan key:generate

This command will generate a unique application key and populate it into the .env file.

5. Configuring Mail Settings

Laravel supports multiple mail service providers, such as SMTP and Sendmail. Open the .env file and modify the following options.

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
MAIL_USERNAME=yourusername@gmail.com
MAIL_PASSWORD=yourpassword
MAIL_ENCRYPTION=tls

Gmail is used as an example here. You will need to change the MAIL_USERNAME and MAIL_PASSWORD options to your own email credentials, and change the other options as needed.

6. Configure storage directory permissions

Laravel uses the storage directory by default to store files generated by the application, such as logs and caches. In order to ensure that Laravel can access the directory normally, its permissions need to be set to writable. Run the following command in the terminal.

chmod -R 777 storage/

7. Final step

Now, you have configured Laravel. Start the Laravel server with the following command.

php artisan serve

Visit http://localhost:8000 in the browser. You will see a Laravel welcome page, indicating that you have successfully installed and configured the Laravel framework.
