Mongodb v3.4
MongoDB v3.4
You need to do the following to create a secure database:
您需要执行以下操作来创建安全数据库：
Make sure the user starting the process has permissions and that the directories exist (/data/dbin this case).
确保启动该进程的用户具有权限并且目录存在（/data/db在本例中）。
1) Start MongoDB without access control.
1）在没有访问控制的情况下启动MongoDB。
mongod --port 27017 --dbpath /data/db
2) Connect to the instance.
2) 连接到实例。
mongo --port 27017
3) Create the user administrator (in the admin authentication database).
3）创建用户管理员（在admin认证数据库中）。
use admin
db.createUser(
{
user: "myUserAdmin",
pwd: "abc123",
roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
}
)
4) Re-start the MongoDB instance with access control.
4) 重启带有访问控制的MongoDB实例。
mongod --auth --port 27017 --dbpath /data/db
5) Connect and authenticate as the user administrator.
5) 以用户管理员身份进行连接和验证。
mongo --port 27017 -u "myUserAdmin" -p "abc123" --authenticationDatabase "admin"
6) Create additional users as needed for your deployment (e.g. in the test authentication database).
6) 根据您的部署的需要（例如在测试认证数据库中）创建额外的用户。
use test
db.createUser(
{
user: "myTester",
pwd: "xyz123",
roles: [ { role: "readWrite", db: "test" },
{ role: "read", db: "reporting" } ]
}
)
7) Connect and authenticate as myTester.
7) 以 myTester 身份连接并进行身份验证。
mongo --port 27017 -u "myTester" -p "xyz123" --authenticationDatabase "test"
I basically just explained the short version of the official docs here: https://docs.mongodb.com/master/tutorial/enable-authentication/
我基本上只是在这里解释了官方文档的简短版本：https: //docs.mongodb.com/master/tutorial/enable-authentication/

You need to delete your old db folder and recreate new one. It will resolve your issue.
您需要删除旧的 db 文件夹并重新创建新文件夹。它将解决您的问题。
