With the rapid development of internet technologies, PHP has become one of the most widely used programming languages, gaining increasing popularity among developers. In the process of PHP project development, deployment is a crucial step. However, traditional manual deployment methods are prone to errors and time-consuming. Therefore, finding an efficient and automated deployment tool is vital.
Deployer is an automated deployment tool based on PHP, which helps developers easily implement project deployment, saving time and preventing human errors. In this article, I will introduce the installation, configuration, and usage of Deployer, along with practical code examples.
Deployer can be installed via Composer, so the first step is to ensure that Composer is installed. If you haven’t installed Composer yet, you can visit the official Composer website for installation.
After installing Composer, navigate to your project root directory and execute the following command to install Deployer:
composer require deployer/deployer --dev
Create a file named deploy.php in the project root directory to configure the necessary parameters for Deployer. Below is a simple configuration example:
<?php
require 'vendor/autoload.php';
set('application', 'Your Application');// Project name
set('repository', 'git@github.com:yourusername/yourrepository.git');// Git repository URL
set('git_tty', false);// Disable interactive tty mode
set('keep_releases', 3);// Keep the last 3 releases
set('shared_files', []);// Shared files
set('shared_dirs', []);// Shared directories
// Server configuration
host('your-server-ip')
->user('your-username')
->identityFile('~/.ssh/id_rsa')
->set('deploy_path', '/var/www/html');// Server deployment path
// Custom tasks
task('build', function () {
run('cd {{release_path}} && build');
});
// Post-deployment tasks
after('deploy', 'build');
After the configuration is completed, run the following command to deploy the project:
dep deploy
Once this command is executed, Deployer will automatically pull the latest code from the Git repository and deploy it to the specified server path. If custom tasks are defined (like the build task above), Deployer will execute these tasks after completing the deployment.
Deployer also supports rolling back to a previous version if something goes wrong. You can use the following command to roll back:
dep rollback
Deployer will automatically roll the project back to the previous version and deploy it on the server.
By using Deployer, developers can easily automate PHP project deployments, reduce human errors, and improve efficiency. Deployer is easy to use, flexible in configuration, and supports task extensions, making it perfect for rapid deployment of small to medium-sized projects.
We hope this article has helped you understand and use Deployer to its fullest potential, improving your PHP project deployment efficiency and quality.
