The invention relates to a multi-level multi-tenant cross
authorization management method, which comprises the following steps: defining a plurality of management roles in different organizations, and carrying out access permission and resource configuration on the management roles; selecting cross-
server users in different organizations from the management role, and mounting the cross-
server users on the management role to form a cross management role; and presetting a role consignment rule, and endowing the cross management role to a user according to the role consignment rule. The cross
authorization and resource access of different management nodes can be carried out across organizations, the
authorization tree can realize cross authorization management on all tenants, the authorization trees of all roles do not need to be modified in batches for newly introduced tenants, and the
workload is very small. According to the invention, on the basis of a plurality of stackable tree-shaped management architectures, a plurality of
layers of special management relationships are stacked, and cross authorization of a classical architecture and special requirements is considered, so that a management architecture which cannot be realized by a multi-tenant
system of a traditional tree-shaped management architecture can be met.
