2. Open-IM relies on five open source high-performance components: **Etcd**, **MySQL**, **MongoDB**, **Redis**, **Kafka**. Before you deploy Open-IM privately, please make sure that you have installed the above five components and **check the component parameters ** in the configuration file. If your server does not have the above components, you must install the missing components first. **If you have the above components, it is recommended to use them directly, if not, Docker installation is recommended, which is faster and more convenient**.
