我已經在本地機器上設置了一個mongodb副本集，並在名爲「adaptive-db」的數據庫中創建了幾個集合。從mongo shell中，當我連接到主節點並運行show dbs時，我可以看到並查詢我的數據庫「adaptive-db」。MongoDB輔助副本沒有集合，因爲在主節點
然後，我切換到輔助，並運行rs.slaveOk（）期望看到primary中創建的「adaptive-db」也存在於輔助中，但我沒有看到它。
這裏是我跑的命令：
shell:bin user1$ ./mongo localhost:27017
MongoDB shell version: 3.0.2
connecting to: localhost:27017/test
rs0:PRIMARY> show dbs
adaptive-db 0.125GB
local 0.281GB
rs0:PRIMARY> use adaptive-db
switched to db adaptive-db
rs0:PRIMARY> show collections
people
student
system.indexes
rs0:PRIMARY> db.people.find().count()
6003
rs0:PRIMARY> exit
bye
shell:bin user1$ ./mongo localhost:27018
MongoDB shell version: 3.0.2
connecting to: localhost:27018/test
rs0:SECONDARY> show dbs

有人可以PLZ解釋我爲什麼？這裏是我的rs.conf（）：
rs0:SECONDARY> rs.conf()

"version" : 7,
"members" : [
{
"_id" : 0,
