Note: if you have already created a RED metadata repository then go directly to step 5.
1. Create a database, admin role and admin
...
user in PostgreSQL
Code Block | ||
---|---|---|
| ||
-- Create an admin role, database and grant create CREATE ROLE redadmin_role NOLOGIN ADMIN postgres; CREATE DATABASE redrepo_db; GRANT CREATE ON DATABASE redrepo_db to redadmin_role; |
...
Create an your RED admin user
...
:
Code Block | ||
---|---|---|
| ||
-- Create the admin user CREATE USER redadmin_user WITH PASSWORD 'mypass'; GRANT redadmin_role to redadmin_user; |
...
2. Create an ODBC DSN for the database
Note: it is not recommended to enter username and password into the DSN as this will allow anyone with access to this machine to login to the database without credentials. Additionally the PostgreSQL driver does not currently store the password securely on Windows.
...
3. Install the RED metadata repository
You must install the RED (and Azkaban) metadata repositories prior to assigning permissions to individual users as permission setting in PostgreSQL only grants permissions on the existing objects in the database or schema at the time the grant was given.
...
- RedSchedulerInstaller.exe - Windows GUI based installation wizard
- azkaban-installer.jar - Java based command line installation for both Windows and Linux
...
4. Create a RED User role and user in PostgreSQL
It is important to make sure you have completed step 4 prior to running the following user grants.
...
Code Block | ||
---|---|---|
| ||
-- Create a RED user and grant the user role CREATE USER red_user WITH PASSWORD 'red_pass'; GRANT reduser_role to red_user; |
...
5. Create a RED Scheduler role and user in PostgreSQL
It is important to make sure you have completed step 4 prior to running the following user grants.
Code Block | ||
---|---|---|
| ||
-- Note this set of statements assumes you have already created -- the RED Metadata using the admin user. -- Create the RED Scheduler user role and give grants to the metadata objects CREATE ROLE redscheduler_role NOLOGIN ADMIN postgres; -- RED 'red' schema permissions GRANT USAGE ON SCHEMA red TO redscheduler_role; GRANT EXECUTE ON ALL FUNCTIONS IN SCHEMA red TO redscheduler_role; GRANT EXECUTE ON ALL PROCEDURES IN SCHEMA red TO redscheduler_role; -- We can potentially grant "INSERT, UPDATE, DELETE" to only the ws_wrk tables here, but we still need select on the rest GRANT SELECT, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA red TO redscheduler_role; -- Grant redscheduler_role select access to the redadmin schema GRANT USAGE ON SCHEMA redadmin TO redscheduler_role; GRANT SELECT ON ALL TABLES IN SCHEMA redadmin TO redscheduler_role; -- Create the RED scheduler user and grant the RED Scheduler role CREATE USER redscheduler_user WITH PASSWORD 'redscheduler_pass'; GRANT redscheduler_role to redscheduler_user; -- [OPTIONALLY] create the RED Scheduler Profile Role and User, or just use the redadmin_user for Profile maintenance CREATE ROLE redschedulerprofile_role NOLOGIN ADMIN postgres; -- RED 'red' schema permissions GRANT USAGE ON SCHEMA red TO redschedulerprofile_role; GRANT SELECT ON ALL TABLES IN SCHEMA red TO redschedulerprofile_role; -- RED 'redadmin' schema permissions GRANT USAGE ON SCHEMA redadmin TO redschedulerprofile_role; GRANT SELECT, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA redadmin TO redschedulerprofile_role; -- Create a RED profile admin user and grant the user role CREATE USER redschedulerprofile_user WITH PASSWORD 'red_pass'; GRANT redschedulerprofile_role to redschedulerprofile_user; |
...
6. Create a Azkaban User role and user in PostgreSQL
Code Block | ||
---|---|---|
| ||
-- Note this set of statements assumes you have already created
-- the Azkaban Metadata using the redadmin_user.
-- Create the Azkaban metadata user role and give grants to the Azkaban metadata objects in schema 'white'
CREATE ROLE azkabanmeta_role NOLOGIN ADMIN postgres;
-- Azkaban 'white' schema permissions
GRANT USAGE ON SCHEMA white TO azkabanmeta_role;
GRANT USAGE ON ALL SEQUENCES IN SCHEMA white TO azkabanmeta_role;
GRANT EXECUTE ON ALL FUNCTIONS IN SCHEMA white TO azkabanmeta_role;
GRANT EXECUTE ON ALL PROCEDURES IN SCHEMA white TO azkabanmeta_role;
GRANT SELECT, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA white TO azkabanmeta_role;
-- Create a Azkaban meta user and grant the user role
CREATE USER azkabanmeta_user WITH PASSWORD 'azkabanmeta_pass';
GRANT azkabanmeta_role to azkabanmeta_user;
