Deployer Best Practices: Efficient PHP Project Deployment Tutorial

Introduction

With the development of the internet, web application development and deployment have become increasingly complex. To improve development efficiency and deployment quality, automation deployment has become an essential step. This article will introduce how to use the Deployer tool for automated deployment of PHP projects, along with some practical code examples.

What is Deployer

Deployer is an open-source automation deployment tool written in PHP, designed to help developers quickly and reliably automate the deployment of their PHP applications. It is simple to use, powerful, and highly customizable, making it suitable for projects of various scales.

Why Choose Deployer

Deployer has several advantages, here are some key reasons why developers choose it:

• Easy to Use: With simple command-line tools and configuration files, Deployer makes it easy to define deployment tasks with almost no learning curve.
• Powerful: Deployer supports multiple deployment methods such as FTP, SFTP, Git, RSync, and can flexibly meet the needs of different projects.
• Highly Customizable: Deployer provides rich plugins and tasks, allowing developers to tailor deployment tasks according to project requirements, such as database migrations and cache clearing.

Deployer Installation and Configuration

Installing Deployer is very simple, just run the following command via Composer:

<span class="fun">composer require deployer/deployer</span>

Next, create a file named deploy.php in your project's root directory and add the following basic configuration:

require 'recipe/composer.php'; // Import the composer plugin
require 'recipe/symfony.php'; // Import the Symfony plugin

// Server connection configuration
server('production', 'your_server_ip')
    ->user('your_username')
    ->password('your_password')
    ->set('deploy_path', '/var/www/html');

// Project configuration
set('repository', 'https://github.com/your_username/your_repository.git');
set('keep_releases', 3);

// Task configuration
task('deploy:custom_task', function () {
    // Custom task logic
})->desc('Custom Task');

Writing Deployment Scripts

Deployer allows you to define multiple tasks to perform different deployment operations. Below is an example of a deployment task:

task('deploy', [
    'deploy:prepare', // Prepare for deployment
    'deploy:lock', // Lock deployment
    'deploy:release', // Release code
    'deploy:update_code', // Update code
    'deploy:vendors', // Install dependencies
    'deploy:clear_paths', // Clear invalid paths
    'deploy:symlink', // Create symlink
    'deploy:unlock', // Unlock deployment
    'cleanup', // Clean old versions
    'success', // Success message
])->desc('Deploy your project');

You can write custom deployment tasks as per your project needs, for example, a database migration task:

task('deploy:migrate', function () {
    run('cd {{release_path}} && php artisan migrate');
})->desc('Database migration');

Running the Deployment Script

To start the deployment, run the following command:

<span class="fun">dep deploy</span>

Deployer will automatically connect to the server, pull the code from the repository, and execute the defined deployment tasks. You can view the deployment progress and results in the output logs.

Conclusion

By using Deployer for PHP project automation deployment, developers can greatly improve deployment efficiency and reduce the likelihood of errors. This article covers the installation and configuration of Deployer, and provides examples of common tasks. We hope this helps you make better use of Deployer for project deployment.
