Starting from scratch: A complete guide to configuring and deploying PHP projects using Deployer

Introduction:
In a modern development environment, configuring and deploying a PHP project is a very important step. Deployer is a powerful automated deployment tool that can help us easily build, configure and deploy PHP projects. This article will introduce you how to use Deployer to complete these tasks, with code examples.

Part One: Install Deployer

First, we need to install Deployer. Open a command line and enter the following command:

$ composer require deployer/deployer --dev

This will install Deployer in your project. Next, we will create a deploy.php file in the project root directory, which is the Deployer configuration file.

Part 2: Configure Deployer

In the deploy.php file, we need to configure some basic settings so that Deployer can correctly deploy our project. The following is an example configuration:

<?php
namespace Deployer;

require_once 'vendor/autoload.php';

// 服务器连接
host('your-server-ip')
    ->user('your-username')
    ->port(22)
    ->identityFile('~/.ssh/id_rsa')
    ->set('deploy_path', '/var/www/html');

// 项目设置
set('repository', 'git@github.com:your-username/your-project.git');
set('branch', 'master');
set('keep_releases', 3);

// 任务定义
task('deploy', function () {
    // 上传代码
    upload('path/to/your/local/project', '{{release_path}}');

    // 更新项目依赖
    run('cd {{release_path}} && composer install');

    // 迁移数据库
    run('cd {{release_path}} && php artisan migrate');

    // 切换到最新的发布版本
    run('ln -sfn {{release_path}} {{deploy_path}}/current');

    // 清理旧版本
    cleanup();
});

// 执行部署任务
after('deploy:failed', 'deploy:unlock');

In this example configuration, we first specify the IP address, username, port and key file of the server to connect to via the host() method . Then, we specify the repository and branch to deploy to. The keep_releases option specifies the number of releases to keep. In the task definition, we define a task named deploy, which includes the steps of uploading code, updating project dependencies, migrating the database, switching to the latest release version, and cleaning up old versions. Finally, we specify to unlock the server if deployment fails via the after() method.

Part 3: Perform Deployment

Now, we have completed the configuration of Deployer. Next, simply execute the following command in the command line to perform deployment:

$ dep deploy

This will trigger Deployer to start the deployment process. Deployer will execute the tasks we defined in the configuration file in sequence.

Conclusion:
Configuring and deploying PHP projects is an important development link and a key step to ensure the successful launch of the project. Using Deployer can simplify this process, allowing us to complete the configuration and deployment tasks more easily. This article provides you with a complete guide to configuring and deploying PHP projects using Deployer, and provides relevant code examples. I hope this article is helpful to you, and I wish you success in configuring and deploying your project!
