The invention discloses an implementation method and device of Redis universal middleware. The method comprises: a piece of middleware receives a reading/writing request sent by an application; the middleware determines a processing entity corresponding to the reading/writing request from processing entities connected with the middleware; the middleware obtains an available connecting link from a connection pool of the processing entity corresponding to the reading/writing request, and sends the reading/writing request through the connecting link. The method and the device are used to solve the problem that techniques for visiting a Redis database in the prior art are not universal.
