Create phabricator user to be used in phabricator config
Grant the above user CREATE TABLESPACE permission so he can create DB
Grant all permissions on the phabricator tables to the above user (daemons/upgrade scripts require different permissions – the permission list from the doc wasn’t enough, so I granted all permission to the user)


CREATE USER 'phabricator'@'%' IDENTIFIED BY '{password}';
GRANT CREATE TABLESPACE ON `phabricator\_%` TO 'phabricator'@'%';
GRANT ALL ON `phabricator\_%`.* TO 'phabricator'@'%';
