Database Configuration Overview

Database Configuration Overview

Default database (H2)

When you install the vanilla standalone rundeck configuration, it will use H2, an embedded database. It is convenient to have an embedded database when you are just trying Rundeck or using it for a non-critical purpose. Be aware though that using the H2 database is not considered safe for production because it not resilient if Rundeck is not shutdown gracefully. When shutdown gracefully, Rundeck can write the data (kept in memory) to disk. If Rundeck is forcefully shutdown, the data can not be guaranteed to be written to file on disk and cause truncation and corruption.

Don't use the H2 embedded database for anything except testing and non-production.

Use an external database service like MariaDB, Mysql, Postgres, Amazon Aurora or Oracle.

Note: For concerns about CVE-2022-45868 please see the write up why Rundeck is not vulnerable.

Database Architecture and Performance Notes

Process Automation supports only one active DB instance serving queries to the Enterprise Cluster. PAOP only supports reading from and writing to a single database instance from all servers in the same cluster. For optimal performance the Process Automation Enterprise Cluster and database instance need to be connected on low latency network (<40ms latency).

Customize the Datasource

The dataSource is configured in the file.

You specify the dataSource. configuration properties.

Here is the default, set up for the default embedded H2 database:

dataSource.url = jdbc:h2:file:/var/lib/rundeck/data/rundeckdb;DB_CLOSE_ON_EXIT=FALSE;NON_KEYWORDS=MONTH,HOUR,MINUTE,YEAR,SECONDS

dataSource.dbCreate specifies how the behavior that Hibernate should take when it generates the schema for your database. The default value of update means that it will attempt to create the database schema if it does not exist, and update it if necessary if it already exists.

dataSource.url specifies the connection URL for the data source.

If necessary, you may have to specify other dataSource properties, such as username and password, depending on the type of database. See the sections below for your specific Database type.

Add the JDBC Driver

Rundeck includes a JDBC driver for Mysql, MariaDB, Postgres, MSSQL and H2. If you are using another database or if you want to use an updated driver, copy the appropriate JDBC driver (e.g.,"ojdbc14.jar" for Oracle,or "aws-mysql-jdbc.jar" for Amazon Aurora) into the server lib dir:

cp ojdbc14.jar $RDECK_BASE/server/lib


For RPM and DEB you should create /var/lib/rundeck/lib folder and place the driver there.


You must establish a JDBC connection for every job you expect to be running simultaneously (we suggest for # of connections to equal number of jobs * 2 | 3). So if you expect to have two jobs running simultaneously, we recommend a minimum of 4 connections.
