By default, Fedora comes configured to write binary resources (i.e. files) to the file system and RDF resources (i.e. objects) to a database. For testing, a file-based objects database may be usefulAll of Fedora's content and metadata are stored on disk in an OCFL storage root. For performance reasons, Fedora maintains a cache of system and user metadata in a rebuildable database. For quickly spinning up Fedora in a testing / experimental context, a default H2 database is available by default. However, for production installations, it is recommended to use a MariaDB, MySQL or PostgresSQL object storePostgreSQL database. Below are the steps to use MySQL or PostgreSQL, as well as Docker instructions if you choose to run your database in a Docker container.
MySQL
- Install an instance of MySQL and create a database called
fcrepo
and a user account that can access it - Run Fedora with the following
JAVA_OPTS
:
Docker-based Database Setup
The following instructions detail how to run your database in a Docker container.
MariaDB
The following instructions use the database username of "fcrepo-user" and password of "fcrepo-pw". You will want to change these to something more secure.
No Format |
---|
docker run --name f6-mariadb -e MYSQL_ROOT_PASSWORD=root-pw -e MYSQL_DATABASE=fcrepo -e MYSQL_USER=fcrepo-user -e MYSQL_PASSWORD=fcrepo-pw -p 3306:3306 -d mariadb:10.5.3
..when done with the database:
docker stop f6-mariadb
docker rm f6-mariadb |
In order for Fedora to connect with a database configured as above, the Fedora should be started with the following system properties:
No Format |
---|
-Dfcrepo.db.url=jdbc:mariadb://localhost:3306/fcrepo
-Dfcrepo.db.user=fcrepo-user
-Dfcrepo.db.password=fcrepo-pw |
PostgreSQL
The following instructions use the database username of "fcrepo-user" and password of "fcrepo-pw". You will want to change these to something more secure.
No Format |
---|
docker run --name f6-postgres -e POSTGRES_USER=fcrepo-user -e POSTGRES_PASSWORD=fcrepo-pw -e POSTGRES_DB=fcrepo -p 5432:5432 -d postgres:12.3
..when done with the database:
docker stop f6-postgres
docker rm f6-postgres |
In order for Fedora to connect with a database configured as above, the Fedora should be started with the following system properties:
No Format |
---|
-Dfcrepo.db.url=jdbc:postgresql://localhost:5432/fcrepo
-Dfcrepo.db.user=fcrepo-user
-Dfcrepo.db.password=fcrepo-pw |
MySQL
The following instructions use the database username of "fcrepo-user" and password of "fcrepo-pw". You will want to change these to something more secure.
No Format |
---|
docker run --name f6-mysql -e MYSQL_ROOT_PASSWORD=root-pw -e MYSQL_DATABASE=fcrepo -e MYSQL_USER=fcrepo-user -e MYSQL_PASSWORD=fcrepo-pw -p 3306:3306 -d mysql:8.0
..when done with the database:
docker stop f6-mysql
docker rm f6-mysql |
In order for Fedora to connect with a database configured as above, the Fedora should be started with the following system properties:
No Format |
---|
-Dfcrepo.db.url=jdbc:mysql://localhost:3306/fcrepo
-Dfcrepo.db.user=fcrepo-user
-Dfcrepo.db.password=fcrepo-pw |
Native Database Setup
MariaDB
- Install an instance of MariaDB and create a database called
fcrepo
and a user account that can access it - Run Fedora with the following
JAVA_OPTS
:

---|
JAVA_OPTS |
Code Block |
JAVA_OPTS="${JAVA_OPTS} -Dfcrepo.modeshape.configuration=classpath:/config/jdbc-mysql/repository.json" JAVA_OPTS="${JAVA_OPTS} -Dfcrepo.mysql.username=<username>" JAVA_OPTS="${JAVA_OPTS} -Dfcrepo.mysqldb.password=<password>url=jdbc:mariadb://localhost:3306/fcrepo" JAVA_OPTS="${JAVA_OPTS} -Dfcrepo.mysqldb.hostuser=<default=localhost><username>" JAVA_OPTS="${JAVA_OPTS} -Dfcrepo.mysqldb.portpw=<default=3306><password>" |
Note, the the fcrepo
database database must be manually created, but the tables will be automatically created.
PostgreSQL
- Install an instance of PostgreSQL and create a database called
fcrepo
and a user account that can access it - Run Fedora with the following
JAVA_OPTS
:

Note, the fcrepo
database must be manually created, but the tables will be automatically created.
