간단하다. 몇몇 옵션들을 어떻게 추가하는지에 따라 틀릴 뿐 간단하다.

-- Create endpoint on server instance that hosts the secondary replica:

CREATE ENDPOINT Hadr_endpoint

-- If necessary, create a login for the service account, domain_name\user_name

-- of the server instance that will host the other replica:

USE master;

GO

CREATE LOGIN [domain_name\user_name] FROM WINDOWS;

GO

-- And Grant this login connect permissions on the endpoint:

GRANT CONNECT ON ENDPOINT::Hadr_endpoint
