RapidMiner Server home directory
The RapidMiner Server home directory is created automatically by the RapidMiner Server installer – see the installation guide to install and start using RapidMiner Server.
This document outlines the purpose of the various files and subdirectories within the RapidMiner Server home directory.
What is the RapidMiner Server home directory?
The RapidMiner Server home directory is where your RapidMiner Server configuration and data is stored. In particular it stores the contents of the RapidMiner Server repository, including all user data that was uploaded from RapidMiner Studio and generated via RapidMiner processes.
If RapidMiner Server was installed using the installer, the default location of the RapidMiner Server home directory is:
Windows: C:\Users\<user-home>\rapidminer-server\rapidminer-server-home\
Linux: /home/<user-home>/rapidminer-server/rapidminer-server-home/
One RapidMiner Server home directory per RapidMiner Server instance!
You can only have one RapidMiner Server home directory per RapidMiner Server installation. If you have multiple RapidMiner Server installations, you will need to set up a RapidMiner Server home directory for each installation.
Where possible, you should choose a location for your RapidMiner Server home directory that will never need to be moved. Some home contents are location-sensitive, so moving the home directory may corrupt them.
The RapidMiner Server home directory contains the RapidMiner Server repository content. As this content can be uploaded by the user the file system needs to support the UTF-8 charset encoding.
Example configuration for Linux via /etc/environment:
export LANG=en_US.UTF-8
export LANGUAGE=en_US:en
export LC_ALL=en_US.UTF-8
What does the RapidMiner Server home directory contain?
Your RapidMiner Server home directory contains the following directories and files:
| Path | Description |
|---|---|
.RapidMiner/ |
Execution context directory used by RapidMiner Core. |
data/ |
Data directory which contains persistent data like the repository content and caches. |
data/repository/ |
Contains the repository content. |
configuration/ |
Contains application configuration. |
configuration/standalone.xml |
Allows configuring various aspects of how RapidMiner Server behaves, such as its database connection, exposed ports, etc. |
job-agent-home/ |
Home folder of the bundled Job Agent. |
resources/jdbc/ |
Contains externally installed JDBC drivers. See creating DB connections for more information. |
resources/extensions/ |
Contains extensions used by RapidMiner Server. See how to install extensions for more information. |
resources/licenses/ |
Contains the RapidMiner Server license(s). |
resources/libs/ |
Contains custom Java libraries which are used in a RapidMiner process. |
resources/modules/ |
Contains external JBoss modules, by default RapidMiner Server's JDBC driver is placed within this directory. |
log/ |
Contains log files for RapidMiner Server. |
Setting the RapidMiner Server home directory
Note that the RapidMiner Server home directory is created automatically by the RapidMiner Server installer.
The home directory location is defined either by the RAPIDMINER_SERVER_HOME environment variable, or in the RAPIDMINER_SERVER_HOME line of:
Windows: <RapidMiner Server installation directory>\bin\standalone.conf.bat
Linux: <RapidMiner Server installation directory>/bin/standalone.conf
Securing the RapidMiner Server home directory
The repository data, the standalone.xml, and other configuration files all contain information that may be considered secret (server settings, repository content, database passwords, etc).
For production use, we strongly recommend that you secure this directory against unauthorized access.
We recommend the following precautions:
Assign a separate restricted user account on the machine for running RapidMiner Server (not a root/administrator user)
If you wish to run RapidMiner Server on port 80, use a reverse proxy server like Apache HTTP Server or nginx (do not run as root/Administrator if security of the home directory is important to you)
Ensure that only the user running RapidMiner Server can access the RapidMiner Server home directory, and that this user has read, write and execute permissions, by setting file system permissions appropriately for your operating system.
- Do not use the embedded Job Agent. Instead configure external Job Agents and use a different user account that is not allowed to access the RapidMiner Server home directory.
- Ensure that your file system is encrypted (e.g. via eCryptfs, dm-crypt, EFS or FileVault)
About the RapidMiner Server repository
As noted above, data/repository/ contains the repository content being managed by RapidMiner Server. We strongly recommend that customers never modify it, nor interact with it directly.
