Laravel development: How to use Laravel Envoyer to achieve seamless deployment?

Laravel is a very excellent PHP development framework and has been selected as one of the most popular PHP frameworks on GitHub. However, during the development process, it is inevitable to encounter deployment problems, especially when the project becomes more and more complex. Laravel Envoyer is a professional deployment tool launched by Laravel. It can solve many tedious and complex problems in the deployment process, such as database migration, code backup, etc. In this article, I will introduce how to use Laravel Envoyer to achieve seamless deployment.

First, we need to enable SSH key authentication for Laravel Envoyer. To do this, you need to make sure you have an OpenSSH key installed and the public key configured according to Envoyer's documentation. This step is very important because Envoyer requires an SSH key to connect to the remote server. Without the correct SSH key configuration, Envoyer will not be able to execute remote commands.

Next, we need to set up the server in Envoyer. After clicking the "Add Server" button, just enter the server's name, IP address, and SSH port to connect to the server. Make sure the information you enter is correct, Envoyer will not be able to connect to the server and perform deployment operations.

Then, we need to add our application to Envoyer. This can be done by selecting Add App in the console. After adding the app, Envoyer will ask us to enter details about the app, such as the app name, the GitHub repository it is bound to, and the web server. When this information is configured, Envoyer will connect to our GitHub repository, pull code from the repository via SSH, and run the application on the server.

Now, we need to configure the target path of the server in the Envoyer console. This path refers to the currently deployed application, including all source code, dependent libraries, static files, etc. In the "Deployment Process" tab, we can configure the target path for each environment and set specific commands that need to be run. For example, in a production environment, we can set up commands in the deployment process to update dependencies, compile resources, and perform database migrations, etc.

We can also use some advanced features of Envoyer, such as script deployment, multi-server deployment support, etc. Scripted deployment and multi-server deployment will allow us to customize our deployment process with more flexibility and deploy applications on multiple servers simultaneously. These advanced features require some basic knowledge and experience with Laravel, but they are crucial for developers.

Finally, after we have completed all the necessary configuration, we can create a new "deployment process" in the console and bind it to the application's environment. In this process, we will perform various deployment tasks such as updating source code, updating dependencies, compiling resources, and performing database migrations, etc. Once the deployment process is triggered, Envoyer will connect to our server and automatically complete all required tasks.

In short, Laravel Envoyer is a very useful deployment tool that allows us to easily deploy applications between different environments. We only need to spend a little time configuring it to achieve seamless deployment, making our Laravel applications more stable and reliable.
