By default, Fedora comes configured to write binary resources (i.e. files) to the file system and RDF resources (i.e. objects) to a LevelDB database. It is often desirable to replace the LevelDB database with a different object store. As of 2016-03-04, the configuration for MySQL or PostgreSQL databases are available within the deployable Fedora war file. Below are the steps to use MySQL or PostgreSQL instead of LevelDB.

Performance Note: For ModeShape configured to use Infinispan, it may be desirable to index the 'version' column of the 'ispn_entry_FedoraRepository' table. See discussion at https://groups.google.com/d/topic/fedora-tech/dnyGQvatIfU/discussion and Infinispan issue https://issues.jboss.org/browse/ISPN-6710. |
MySQL
- Install an instance of MySQL and create a database user account
Run Fedora with the following
JAVA_OPTS
:Code Block JAVA_OPTS="${JAVA_OPTS} -Dfcrepo.modeshape.configuration=classpath:/config/jdbc-mysql/repository.json" JAVA_OPTS="${JAVA_OPTS} -Dfcrepo.ispn.mysql.username=<username>" JAVA_OPTS="${JAVA_OPTS} -Dfcrepo.ispn.mysql.password=<password>" JAVA_OPTS="${JAVA_OPTS} -Dfcrepo.ispn.mysql.host=<default=localhost>" JAVA_OPTS="${JAVA_OPTS} -Dfcrepo.ispn.mysql.port=<default=3306>"
