# Redis not emitting events When you create a new Medusa server, Redis is disabled by default. Instead, a fake Redis server is used that allows you to start your project but does not actually emit any events. To enable a real Redis server, you need to install Redis on your machine and configure it with Medusa. You can learn how to [install Redis in the Set Up your Development Environment documentation](../tutorial/0-set-up-your-development-environment.mdx#redis). After installing it, make sure to configure your Medusa server to use Redis: ```jsx module.exports = { projectConfig: { //... redis_url: REDIS_URL, }, } ``` By default, Medusa connects to Redis over the URL `redis://localhost:6379`. If you need to change that URL, set the following environment variable: ```bash REDIS_URL= ``` ## Additional Resources - Learn how to [set up your development environment](../tutorial/0-set-up-your-development-environment.mdx). - Learn how to [configure your server](../usage/configurations.md).
