Abstract As a new class of erasure codes, locally repairable codes (LRCs) can provide data repair capability for distributed storage system. In this paper, we firstly propose an effective construction method to obtain optimal LRCs based on ternary optimal codes. Then, three classes of optimal LRCs are constructed by ternary cyclic codes and constant cyclic codes. All codes we gained have the optimal distance and reach the Cadambe-Mazumdar (C-M) bound.
