Best Practice: Use Deployer for automated deployment of PHP projects
Introduction:
With the development of the Internet, the development and deployment of web applications have become more and more complex. In order to improve development efficiency and deployment quality, automated deployment has become an important link. This article introduces a best practice method for automated deployment of PHP projects using Deployer and gives some code examples.
1. What is Deployer
Deployer is an open source automated deployment tool written based on PHP. It can help developers automatically deploy their PHP applications quickly and reliably. Deployer is easy to use, powerful and highly customizable, making it suitable for projects of all sizes.
2. Why choose Deployer
3. Installation and configuration of Deployer
Installation: Install through Composer, just run the following command:
composer require deployer/deployer
Configuration: Create a deploy.php
file in the project root directory and configure it as follows:
require 'recipe/composer.php'; // 导入composer插件 require 'recipe/symfony.php'; // 导入symfony插件 // 服务器连接配置 server('production', 'your_server_ip') ->user('your_username') ->password('your_password') ->set('deploy_path', '/var/www/html'); // 项目配置 set('repository', 'https://github.com/your_username/your_repository.git'); set('keep_releases', 3); // 任务配置 task('deploy:custom_task', function () { // 自定义任务逻辑 })->desc('Custom Task'); // 其它任务配置...
4. Write the deployment script
Through Deployer, multiple tasks can be defined to complete different deployment operations. The following is the code for a sample task:
task('deploy', [ 'deploy:prepare', // 准备部署 'deploy:lock', // 加锁 'deploy:release', // 发布代码 'deploy:update_code', // 更新代码 'deploy:vendors', // 安装依赖 'deploy:clear_paths', // 清除无效路径 'deploy:symlink', // 创建软链接 'deploy:unlock', // 解锁 'cleanup', // 清理旧版本 'success', // 成功提示 ])->desc('Deploy your project');
You can write custom deployment tasks according to your project needs. For example, you can add a database migration task:
task('deploy:migrate', function () { run('cd {{release_path}} && php artisan migrate'); })->desc('Database migration');
5. Run the deployment script
Run the following command to start deployment:
dep deploy
Deployer will automatically connect to the server and transfer the code Pull from the warehouse to the specified directory and execute the defined deployment task. You can view the deployment progress and results in the output log.
6. Conclusion
By using Deployer for automated deployment of PHP projects, developers can greatly improve deployment efficiency and reduce the possibility of errors. This article introduces the installation and configuration methods of Deployer and gives some common task examples. I hope it can help you better use Deployer for project deployment.
