user：用戶名
pwd：密碼
roles：指定用戶的角色，可以用一個(gè)空數(shù)組給新用戶設(shè)定空角色；在roles字段,可以指定內(nèi)置角色和用戶定義的角色。role里的角色可以選：
Built-In Roles（內(nèi)置角色）：
Mongodb中 數(shù)據(jù)庫和集合的創(chuàng)建與刪除

創(chuàng)建集合,刪除集合(一般可以不用創(chuàng)造集合,在插入數(shù)據(jù)時(shí)自動(dòng)可以創(chuàng)建集合):
db.createCollection('col') //創(chuàng)建集合
{ "ok" : 1 }
show collections
