Installation¶
Install CrateDB on different operating systems and environments, for on-premises and development operations.
We recommend to use the package-based installation methods for CrateDB on Debian, Ubuntu, and Derivatives and CrateDB on Red Hat, SUSE, and Derivatives, by subscribing to the corresponding package release channels. Alternatively, you can also do an Installation from Tarball Archive.
Cluster configuration
In most environments, CrateDB is run as a cluster of three or more nodes. Sometimes, it is needed to run a cluster across multiple data centers or availability zones.
Notes
After the installation is finished, the CrateDB service should be up and
running, and will run a HTTP server on localhost:4200. To access the
Admin UI from your local machine, navigate
to:
http://localhost:4200/
Note
CrateDB requires a Java virtual machine to run.
Starting with CrateDB 4.2, Java is bundled with CrateDB, and no extra installation is necessary.
CrateDB versions before 4.2 required a separate Java installation. For CrateDB 3.0 to 4.1, Java 11 is the minimum requirement. CrateDB versions before 3.0 require Java 8. We recommend to use OpenJDK on Linux Systems.
