For mongo 2.6 or greater the /etc/mongod.conf now uses a yaml format.

To enable the oplog add something similar to the below, note the replication: line may already exist, be sure to use spaces.

replication:
  replSetName: rs0
  oplogSizeMB: 100

Full documentation here: https://docs.mongodb.com/manual/reference/configuration-options/#replication-options

I got a reply from the MongoDb Team, and it's working fine.

To enable oplog on a standalone server, start mongo with master options.

On command line start mongod --master.

For conf file append the following line:

master=true
