Configuring Metadata Stores in MySQL

Once you install a MySQL database, you must configure it for Schema Registry and SMM.

  1. Launch the MySQL monitor: 
    mysql -u root -p
  2. Create the database for the Schema Registry and the SMM metastore: 
    
create database registry;
create database streamsmsgmgr;
  3. Create Schema Registry and SMM user accounts, replacing the final IDENTIFIED BY string with your password: 
    
CREATE USER 'registry'@'%' IDENTIFIED BY 'R12$%34qw';
CREATE USER 'streamsmsgmgr'@'%' IDENTIFIED BY 'R12$%34qw';
  4. Assign privileges to the user account: 
    
GRANT ALL PRIVILEGES ON registry.* TO 'registry'@'%' WITH GRANT OPTION ;
GRANT ALL PRIVILEGES ON streamsmsgmgr.* TO 'streamsmsgmgr'@'%' WITH GRANT OPTION ;
    If you cannot grant all privileges, grant the following privileges that SMM and Schema Registry require at a minimum:
    • CREATE/ALTER/DROP TABLE
    • CREATE/ALTER/DROP INDEX
    • CREATE/ALTER/DROP SEQUENCE
    • CREATE/ALTER/DROP PROCEDURE
    For example: 
    grant create session to streamsmsgmgr;
grant create table to streamsmsgmgr;
grant create sequence to streamsmsgmgr;
  5. Commit the operation: 
    commit;
