We study the gauged scotogenic model with emphasis on latest measurement of LHCb anomaly and AMS-02 positron excess. In this model, neutrino masses are induced at one-loop level with 
-odd particles, i.e., right-handed neutrinos 
and inert scalar doublet 
inside the loop. Meanwhile, the gauged symmetry is broken spontaneously by the scalar singlet S, resulting to the massive gauge boson 
. Provided certain couplings to quarks induced by heavy vector-like quarks, the gauge boson would contribute to the transition 
, hence explain the anomaly. As for the Majorana fermion DM N, the gauge boson and the singlet Higgs 
will generate various annihilation channels, among which the 
and 
channel could be used to interpret the AMS-02 positron excess. We give a comprehensive analysis on model parameter space with consider various current constraints. The combined analysis shows that the anomaly and AMS-02 positron excess can be explained simultaneously.
