Managing WordPress configuration across multiple environments is a common challenge for developers. Settings, plugins, themes, and options differ between local, staging, and production environments. WP-CLI provides powerful commands for exporting and importing configuration, making it possible to replicate environments consistently.
This guide covers how to manage WordPress configuration using WP-CLI and configuration management techniques.
File di Configurazione
WordPress configuration is split between wp-config.php (server settings) and the database (site settings). Use environment-specific wp-config.php files that load different settings based on the environment. Define constants like WP_DEBUG, DB_HOST, and DB_NAME conditionally. Use the WP_ENVIRONMENT_TYPE constant to detect the current environment.
Create separate configuration files for each environment and include them from wp-config.php based on the environment constant.
Exporting Configuration
Use WP-CLI’s wp config commands to export WordPress settings. wp option get retrieves specific option values. wp plugin list exports a list of installed plugins with their status. wp theme list exports theme information. Combine these into a configuration script that can be run on another environment.
Exporting configuration as a script that can be re-run makes environment setup reproducible and auditable.
Importing Configuration
Run WP-CLI commands to apply configuration to a new environment. wp option update sets options. wp plugin activate activates plugins. wp theme activate activates themes. Create a setup script that runs all necessary WP-CLI commands to configure a fresh WordPress installation to match your desired state.
Test your configuration script on a fresh installation to verify it produces the expected result.
WordPress Salts
WordPress salts are security keys that encrypt cookies and authentication tokens. Each environment should have unique salts. Generate salts with wp config shuffle-salts. Never share salts between environments — this compromises security. Store salts in environment-specific files that aren’t committed to version control.
Regenerate salts periodically as a security measure. Use wp config shuffle-salts to generate new salts safely.
Automating Setup
Create a bootstrap script that configures a new WordPress installation from scratch. Download WordPress, create the database, install WordPress, activate plugins, activate the theme, import settings, and configure permalinks. A single script can set up a complete environment in minutes, eliminating manual configuration errors.
Store your bootstrap script in version control alongside your project files. Document any manual steps that can’t be automated.
Il punto fondamentale
Managing WordPress configuration with WP-CLI makes environment setup reproducible and auditable. Use WP-CLI to export and import configuration, manage salts per environment, and create automated setup scripts. Configuration management reduces setup errors and ensures consistency across environments.
