SilverStripe 4数据库配置位置咨询：安装后mysite/_config.php为空

Hey there, I totally get why this feels confusing—SilverStripe 4 made a pretty big shift away from the old way of storing database config directly in _config.php!

Starting with version 4.0.0, the framework switched to using environment variables stored in a .env file for sensitive stuff like database credentials, instead of hardcoding them in PHP files. Here's exactly where to find and set this up:

• First, check your project root directory (the same place where your mysite folder lives) for a file named .env. If it's not there, you'll almost always find a sample file called .env.example—just copy that file and rename it to .env.
• Open up the .env file, and you'll spot these key variables that control your database connection:
  • SS_DATABASE_NAME: This is your database's name
  • SS_DATABASE_USERNAME: The username for accessing the database
  • SS_DATABASE_PASSWORD: The password paired with that username
  • SS_DATABASE_SERVER: (Optional, defaults to localhost) The address of your database server

As for why your mysite/_config.php is empty? That's totally intentional now. Most configuration in SilverStripe 4 is handled via YAML files and environment variables instead of the old PHP config file approach. Using .env is also way better for security because it keeps sensitive data out of your version control (just make sure .env is added to your .gitignore so it doesn't get committed!).

Quick tip: If you need different config values for different environments (like dev vs production), you can use environment-specific .env files (e.g., .env.dev or .env.prod) or set actual server environment variables if your hosting provider supports that.
