MySQL

MySQL also provides the option to use an externally located database that also supports high availability.

The following steps are required to use MySQL:

1. Download the MySQL JDBC driver and place it somewhere accessible to NiFi Registry

   
   /path/to/drivers/mysql-connector-java-8.0.16.jar
   

2. Create a database inside MySQL (enter mysql shell using mysql -u root -p

   
   CREATE DATABASE nifi_registry;
   

3. Create a database user and grant privileges (for remote users, use nifireg'@'<IP-ADDRESS>, or nifireg'@'% for any remote host)

   
   GRANT ALL PRIVILEGES ON nifi_registry.* TO 'nifireg'@'localhost' IDENTIFIED BY 'changeme';
   

4. Configure the database properties in nifi-registry.properties

   
   nifi.registry.db.url=jdbc:mysql://<MYSQL-HOSTNAME>/nifi_registry
   nifi.registry.db.driver.class=com.mysql.cj.jdbc.Driver
   nifi.registry.db.driver.directory=/path/to/drivers
   nifi.registry.db.username=nifireg
   nifi.registry.db.password=changeme
