Mogodb master slave mode, can oplog be opened in slave?

  mongodb, question

Using the master slave architecture, I want to synchronize the data to other downstream through the oplog in slave, but there seems to be no oplog in slave, and I don’t know if there is no or what parameters to specify.

Master/slave has not been recommended for a long time, please use itreplica setReplace. When oplog is enabled, oplos.rs will appear in the local library, which is oplog.
