Use Deployer to improve the efficiency and quality of PHP project deployment
Introduction:
In daily development work, project deployment is a very important link. The traditional manual deployment method is not only time-consuming and labor-intensive, but also prone to human errors. In order to improve the efficiency and quality of project deployment, we can use some automation tools to simplify the deployment process. This article will introduce how to use Deployer to implement automated deployment and illustrate it through code examples.
composer require deployer/deployer --dev
After the installation is complete, we need to create a deploy.php
file in the project root directory, and Configure Deployer in the file. The following is a simple configuration example:
<?php require 'recipe/common.php'; // 项目名称 set('application', 'my-app'); // 部署服务器 host('production') ->hostname('example.com') ->user('user') ->set('deploy_path', '~/www/{{application}}'); // 项目仓库 set('repository', 'git@github.com:username/repo.git'); // 部署目标分支 set('branch', 'master'); // 其他配置项...
In the configuration file, we can set the project name, deployment server, warehouse address, deployment target branch and other information. According to the needs of the actual project, the relevant items in the configuration file can be modified as needed.
deploy.php
file. The following is an example: <?php // 生成并上传新的代码 task('deploy:update_code', function () { $sourcePath = get('config.source_path'); $releasePath = get('deploy_path') . '/releases/' . date('YmdHis'); // 从Git仓库下载代码 run("git clone {{repository}} $releasePath"); // 其他操作... }); // 安装依赖并进行其他的项目构建操作 task('deploy:build', function () { $releasePath = get('release_path'); // 安装Composer依赖 run("cd $releasePath && composer install --no-dev"); // 其他操作... }); // 部署任务执行完成后的清理操作 task('deploy:cleanup', function () { $releasesPath = get('deploy_path') . '/releases'; // 保留指定数量的历史版本 run("ls -dt $releasesPath/* | tail -n +{{keep_releases}} | xargs rm -rf"); // 其他操作... }); // 默认任务:依次执行deploy:update_code、deploy:build、deploy:cleanup task('deploy', [ 'deploy:update_code', 'deploy:build', 'deploy:cleanup' ]); // 创建一个自定义任务 task('custom_task', function () { // 自定义操作... });
In the above code example, we define three deployment tasks: deploy:update_code
is used to download the latest code, deploy:build
is used to install dependencies and perform other project build operations, deploy:cleanup
is used to clean up historical versions. Finally, we created a default task named deploy
through the task
function, which contains the three previously defined tasks for subsequent deployment.
deploy.php
file, we can execute the deployment through the command line. Switch to the project root directory on the command line, and then execute the following command: dep deploy
Deployer will automatically connect to the remote server and execute the deployment process according to the defined task sequence. In addition, Deployer also provides a series of commands, such as dep init
for initializing the deployment configuration file, dep run
for executing custom tasks on the remote server, etc.
Summary:
Using Deployer can help us simplify and automate the deployment process of PHP projects and improve the efficiency and quality of deployment. Through code examples, we can see that using Deployer in a project can easily define and execute deployment tasks to achieve automated deployment on remote servers. I hope this article can help readers better understand and apply the Deployer tool and improve development efficiency and project quality.
