Use Deployer to implement cross-server PHP project deployment

Introduction:
Deployment is an extremely important step when developing and maintaining large web applications. Deploying PHP projects in a multi-server environment can get complicated, but we can use Deployer to simplify the process. Deployer is a PHP tool for automated project deployment. It can help us deploy projects to multiple servers quickly and reliably.

This article will introduce how to use Deployer to implement cross-server PHP project deployment and provide relevant code examples.

Step 1: Install Deployer
First, install Deployer through Composer. Execute the following command in the command line:

composer require deployer/deployer --dev

Step 2: Configure Deployer
Create a deploy.php file in the project root directory and add the following content:

<?php
require 'recipe/common.php';

// 项目名称
set('application', 'My Project');

// 项目仓库地址
set('repository', '{repository_url}');

// 部署目标服务器
server('staging', 'staging.example.com')
    ->user('deployer')
    ->identityFile()
    ->set('deploy_path', '/var/www/html');

// 部署到服务器的目标路径
set('release_path', '/var/www/html/current');

// 配置部署环境
set('branch', 'master');

// 其他配置项 ...

// 部署前的任务
before('deploy', 'task1');
// 部署后的任务
after('deploy', 'task2');

Step 3: Define the deployment task
Add the following code in the deploy.php file to define our deployment task:

<?php
// 部署完成后执行的任务
task('deploy:cleancache', function () {
    run('{{bin/php}} {{deploy_path}}/current/artisan cache:clear');
});

// 更多任务定义 ...

// 配置部署任务顺序
after('deploy:symlink', 'deploy:cleancache');

Step 4: Execute the deployment
Pass Run the following command on the command line to perform deployment:

dep deploy staging

Here staging is the server name previously defined in the deploy.php file.

Conclusion:
Using Deployer can help us implement cross-server PHP project deployment, greatly simplifying the deployment process. With simple configuration and definition tasks, we can easily deploy the project to multiple servers. Deployer also provides many other functions, such as database migration, file synchronization, etc., which can further expand the deployment tasks as needed.

I hope this article can help you better understand and use Deployer to achieve cross-server deployment of PHP projects. Good luck with your project deployment!
