1st way
第一种方式
I think there should be another user in the db.system.users. If so, please use the saved user to log in.
我认为db.system.users. 如果是这样，请使用保存的用户登录。
If there is NO users in the db.system.users
如果没有用户 db.system.users
> db.system.users.find({})
null
we can access mongodbthrough mongo --port 27017.
我们可以mongodb通过mongo --port 27017.
2nd way - Usual cause of problem
第二种方式 - 问题的常见原因
usesudo mongod --port 27017
用sudo mongod --port 27017
instead ofsudo mongod --auth --port 27017 --dbpath /var/lib/mongodb
代替sudo mongod --auth --port 27017 --dbpath /var/lib/mongodb
note : --authis only required when username& passwordauthenticationis setup
注意：-- auth仅在设置用户名和密码身份验证时才需要
