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 2016-0203-1104, the configuration for a MySQL database is MySQL or PostgreSQL databases are available within the deployable Fedora war file. Below Below are the steps for enabling the to use of MySQL or PostgreSQL instead of the default LevelDB.
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="${JAVA_OPTS} -Dfcrepo.ispn.mysql.port=<default=3306>"
Note, the database and table used by ISPN are auto-created.
PostgreSQL
- Install PostgreSQL and create a database called
ispn
and a user account that can access it - Run Fedora with the following
JAVA_OPTS
:
Code Block |
---|
JAVA_OPTS="${JAVA_OPTS} -Dfcrepo.modeshape.configuration=classpath:/config/jdbc-postgresql/repository.json" JAVA_OPTS="${JAVA_OPTS} -Dfcrepo.ispn.postgresql.username=<username>" JAVA_OPTS="${JAVA_OPTS} -Dfcrepo.ispn.postgresql.password=<password>" JAVA_OPTS="${JAVA_OPTS} -Dfcrepo.ispn.postgresql.host=<default=localhost>" JAVA_OPTS="${JAVA_OPTS} -Dfcrepo.ispn.postgresql.port=<default=5432>" |
Note, the ispn
database must be manually created, but the tables will be automatically created.
