How to Use Deployer to Deploy PHP Applications to Multiple Servers Simultaneously

As the internet continues to develop rapidly, deploying PHP applications to multiple servers has become a common need for many developers. Manual deployment is not only time-consuming but also error-prone. To improve deployment efficiency and reduce errors, automation tools are essential. This article will show you how to use the Deployer tool to automate PHP application deployment on multiple servers.

What is Deployer?

Deployer is a PHP-based automated deployment tool designed to simplify the deployment process of applications. By writing simple configuration files and tasks, developers can quickly deploy applications to multiple servers, saving a lot of time and avoiding the common issues associated with manual deployment.

Installing and Configuring Deployer

1. Install Deployer:
   Execute the following command in the root directory of your project to install Deployer:

composer require deployer/deployer --dev

Deploying PHP Applications with Deployer

1. Deploying to Multiple Servers:
   Run the following command, and Deployer will deploy the application to multiple servers:

dep deploy server1 server2

Deployer will execute the tasks listed in the configuration file and deploy the application to the specified servers, significantly improving work efficiency.

2. Executing Custom Tasks:
   In addition to default deployment tasks, Deployer supports custom tasks. In the configuration file above, we defined a task called build, which will be executed after the deployment is completed. You can add more custom tasks as needed.
