Chcete-li se připojit k primární sadě replik, použijte mongo shell --host
možnost:
mongo --host replicaSetName/host1[:porthost1],host2[:porthost1],host3[:porthost3],etc
Například:
$ mongo --host rs1/john.local:27019,john.local:27018
MongoDB shell version: v3.4.9
connecting to: mongodb://john.local:27019,john.local:27018/?replicaSet=rs1
