Elegant PHP deployment: Use Deployer to improve development efficiency

In web development, deployment is a very important link. The traditional deployment method usually involves tedious operations such as manually copying files and executing commands, which is not only error-prone but also inefficient. Now, with the help of automated deployment tools, we can easily complete the deployment work and improve development efficiency.

This article will introduce an elegant PHP deployment tool - Deployer, and demonstrate how to use this tool for automated deployment through code examples.

1. Introduction to Deployer

Deployer is an open source automated deployment tool developed based on PHP. Its design goals are easy to use and highly scalable. Using Deployer, we can deploy projects by writing concise configuration files without manually executing cumbersome deployment commands.

2. Install Deployer

To use Deployer, you need to install PHP and Composer locally. After the installation is complete, we can install Deployer through Composer.

Open the command line tool and enter the following command to install Deployer globally:

composer global require deployer/deployer
Copy after login

After the installation is complete, we can use Deployer through the dep command.

3. Use Deployer for deployment

Below, we will use a sample project to demonstrate how to use Deployer for automated deployment.

First, we need to create a deploy.php configuration file in the project root directory. This file will contain our deployment script.

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

// 项目名称
set('application', 'myproject');

// 项目远程仓库
set('repository', 'git@github.com:user/repo.git');

// 部署到的服务器
server('production', 'mydomain.com', 22)
    ->user('username')
    ->password('password')
    ->set('deploy_path', '/var/www/html/{{application}}');

// 执行部署
task('deploy', function () {
    // 增量更新代码
    run('cd {{release_path}} && git reset --hard HEAD && git pull origin master');

    // 安装依赖
    run('cd {{release_path}} && composer install');

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

    // 配置文件处理
    run('cd {{release_path}} && cp .env.production .env && php artisan config:cache');

    // 重启服务
    run('sudo service nginx restart');
});

// 将以上步骤绑定到部署命令
after('deploy', 'cleanup');
Copy after login

In the above configuration file, we first introduced the Deployer's basic configuration file using the require function.

Then, we use the set function to set some project-related configurations, such as project name, remote warehouse address, etc.

After that, we use the server function to create a deployment server and set server-related configurations, such as server address, user name, password, etc.

Finally, we use the task function to define a deployment task and write the deployment script in the task. In this example, we first performed an incremental update of the code, then installed project dependencies, updated the database, processed configuration files, etc.

Finally, we use the after function to bind the above operations to the deployment command, so that when we execute the dep deploy command, the above steps will be executed in sequence.

4. Execute deployment

After the configuration is completed, we can switch to the project root directory in the command line tool, and then execute the following command to deploy:

dep deploy
Copy after login

In deployment During the process, Deployer will automatically connect to the remote server we configured and perform the deployment tasks we defined.

When the deployment is completed, we can see the successfully deployed project on the remote server.

Summary

Through the above examples, we can see that using Deployer for automated deployment is very simple, and you only need to write a concise configuration file. This greatly improves development efficiency and reduces the risk of errors caused by manual deployment operations.

Of course, Deployer also provides more functions and scalability, such as supporting simultaneous deployment of multiple servers, hook functions before and after deployment, etc. If you have more complex deployment requirements, you can consult the Deployer official documentation to learn more.

I hope this article can be helpful to you and make you more elegant and efficient in the deployment of PHP projects!
