Use Deployer to achieve flexible deployment and management of PHP projects

With the rapid development of the Internet, PHP has become one of the most popular web development languages. However, developing a PHP project is just the beginning. Deploying the project to an actual server and managing it is an indispensable link. In order to achieve flexible deployment and management, we can use Deployer.

Deployer is an open source tool based on PHP that can help us automatically deploy and manage PHP projects. It uses simple configuration files and command line operations to easily complete the project's automated deployment, version control, server connection, task execution and other functions.

First, we need to install Deployer in the root directory of the project. You can install it by executing the following command through Composer:

composer require deployer/deployer --dev

After the installation is complete, we can create a ## in the root directory of the project. #deploy.php file, used to configure our deployment options. The following is a simple example configuration:

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

// 项目名称
set('application', 'MyApp');

// 项目仓库地址
set('repository', 'git@github.com:yourname/yourrepo.git');

// 服务器连接
server('production', 'yourdomain.com')
    ->user('deployer')
    ->identityFile('~/.ssh/id_rsa')
    ->set('deploy_path', '/var/www/html/myapp');

// 任务：缓存清理
task('clear:cache', function() {
    run('php bin/console cache:clear');
});

// 任务：数据库迁移
task('database:migrate', function() {
    run('php bin/console doctrine:migrations:migrate');
});

// 任务：部署
task('deploy', [
    'deploy:prepare',
    'deploy:lock',
    'deploy:release',
    'deploy:update_code',
    'deploy:shared',
    'deploy:writable',
    'deploy:vendors',
    'database:migrate',
    'clear:cache',
    'deploy:symlink',
    'deploy:unlock',
    'cleanup',
]);

// 配置任务执行路径和用户
set('writable_mode', 'chmod');
set('writable_use_sudo', false);

set('shared_dirs', ['var/logs']);
set('shared_files', ['app/config/parameters.yml']);

// 执行部署
after('deploy', 'cleanup');

// 启用SSH Agent自动添加密钥
set('ssh_type', 'native');
set('ssh_multiplexing', true);

In the above configuration file, we defined the project name, warehouse address, server connection and other information, and added several tasks for application cache cleaning and database migration, etc. operate. The execution order of tasks can be configured according to actual needs.

The configuration file also includes settings for storage paths and user permissions, as well as settings for automatically adding keys using SSH Agent. These settings can be adjusted according to the actual needs of the project.

The process of deploying and managing PHP projects is as follows:

Carry out code development and testing in the local development environment.
1. Use Git to submit code to the project repository.
2. Install Deployer on the development server and create the configuration file.
3. Use command line tools locally to connect to the development server.
4. Use Deployer to execute deployment commands, automatically pull code from the warehouse to the server, and perform various tasks.

Through the above steps, we can easily achieve flexible deployment and management of PHP projects. The one-click deployment function provided by Deployer can greatly improve development efficiency. It also provides flexible configuration options and task management functions, allowing us to conduct customized deployment and management operations according to the characteristics and needs of the project.

To sum up, Deployer is a powerful and flexible PHP project deployment and management tool that can greatly simplify and accelerate the project deployment process. By properly configuring and using Deployer, we can save a lot of time and energy in development and operation and maintenance work, and better manage and maintain our PHP projects.
