To deploy a Symfony application to a production server, follow these steps:
Set up your production server: Make sure you have a server with the necessary software and configurations to run a Symfony application. This typically includes a web server like Apache or Nginx, PHP, and a database server like MySQL or PostgreSQL.
Clone your Symfony project: Clone your Symfony project from your version control system (e.g. Git) onto your production server. Make sure to remove any development-specific files like .env and cache folders.
Install dependencies: Run composer install --no-dev to install all the necessary dependencies for your Symfony project without development dependencies.
Configure environment variables: Update your .env file on the production server with the appropriate environment variables for your production environment, such as database credentials, secret key, and debug mode.
Clear cache: Run php bin/console cache:clear --env=prod to clear the cache for the production environment.
Set permissions: Set the appropriate permissions for the cache and log directories so that your Symfony application can write to them.
Configure web server: Configure your web server (Apache or Nginx) to serve your Symfony application. Make sure to point the document root to the public directory inside your Symfony project.
Set up database: If your Symfony application uses a database, make sure to create the necessary database schema and update the database credentials in your Symfony project configuration.
Test your application: Test your Symfony application on the production server to make sure everything is set up correctly and working as expected.
Monitor and maintain: Monitor your Symfony application on the production server regularly to ensure it is running smoothly and perform any necessary maintenance tasks as needed.
