Return to the installation instructions to complete the RapidMiner Server installation.You can create a database in PostgreSQL using the CREATE DATABASE statement. To use the database you have to use localhost as host, rm_user as user, rm_password as password and rapidminer_serverĪs schema in the RapidMiner Server installer. You now have finished preparing the RapidMiner Server database. Set owner to the new user created in the step above and click Save afterwards. Use rapidminer_server in the Database input field. Right-click on the item Databases, select Create -> Database. In the privileges tab ensure that Can login? is set to Yes. In the definition tab type in the user's password.
