The perfect solution for PHP project deployment: Deployer

With the continuous development of the Internet, PHP, as a widely used programming language, is increasingly favored by developers. In the process of developing a PHP project, project deployment is an essential link. However, the traditional manual deployment method has many inconveniences, such as the need to manually upload files and manually execute commands, which not only wastes time but is also error-prone. Therefore, it is very important to find a convenient and efficient project deployment solution.

Among the many PHP project deployment tools, I recommend using Deployer. Deployer is a deployment tool developed based on PHP, which can easily realize automated deployment of projects. Below I will introduce how to use Deployer and give some sample code.

1. Install Deployer
Deployer is installed through Composer, so Composer needs to be installed first. If you have not installed Composer, you can download the latest installation package at https://getcomposer.org/ and install it according to the official documentation.

After installing Composer, execute the following command in the root directory of the project to install Deployer:

composer require deployer/deployer --dev
Copy after login

2. Configure Deployer
Create a deploy.php file in the root directory of the project for Configure Deployer related parameters. The following is a simple configuration example:

<?php
require 'vendor/autoload.php';

set('application', 'Your Application'); // 项目名称
set('repository', 'git@github.com:yourusername/yourrepository.git'); // 项目的git仓库地址
set('git_tty', false); // 关闭交互式tty模式
set('keep_releases', 3); // 保留最近3个版本的代码
set('shared_files', []); // 共享的文件
set('shared_dirs', []); // 共享的目录

// 服务器配置
host('your-server-ip')
    ->user('your-username')
    ->identityFile('~/.ssh/id_rsa')
    ->set('deploy_path', '/var/www/html'); // 服务器部署路径

// 自定义任务
task('build', function () {
    run('cd {{release_path}} && build');
});

// 发布命令
after('deploy', 'build');
Copy after login

3. Deployment project
After configuring deploy.php, you can execute the following command to deploy the project:

dep deploy
Copy after login

After executing the deployment command Afterwards, Deployer will automatically pull the latest code from the git repository and deploy the code to the specified path on the server. If there are custom tasks (such as the build task above), Deployer will also execute these tasks after deploying the project.

It is particularly worth mentioning that Deployer also provides many common tasks, such as database migration, cache cleaning, etc. The deployment process can be extended by calling the tasks provided by Deployer to meet the needs of different projects.

4. Rollback deployment
Deployer also supports rollback operations of project deployment. You can roll back to the previous version with the following command:

dep rollback
Copy after login

Deployer will automatically roll back the project to the previous version and deploy that version of code on the server.

5. Summary
By using Deployer, we can easily realize automated deployment of PHP projects, improve development efficiency, and reduce the possibility of human errors. Deployer is easy to use, flexible in configuration, and supports task expansion. It is very suitable for rapid deployment of small and medium-sized projects.

I hope this article will help you understand and use Deployer, and I hope you can make full use of this powerful tool to improve the efficiency and quality of PHP project deployment. Thank you everyone for reading!
