The large forward-backward asymmetry of the top quark pair productionmeasured by the hadron colliders shed light on new physics signals beyond theStandard Model. In the Randall-Sundrum model with an additional SU(3) group inthe strong sector, we compare the total cross section and forward-backwardasymmetry of the top quark pair production with the newest data obtained by theCDF and the D0 collaborations. Our numerical analysis shows that the parameter$c_q \gtrsim 0.5$, $c_t \sim -0.6\sim-0.8$, $\tan\phi \gtrsim 20$ or $\tan\phi\leq 1/20$ and the first excitation of axial gluon with a mass about $5\thicksim 6 \mathrm{TeV}$ can accommodate this large anomaly without violatingother experimental constraints.
