In this tutorial, you will learn how to establish a MongoDB to connect with QNAP NAS via QIoT Suite Lite.

Step_1: Open Container Station and Set Up MongoDB

• Click "Container Station".

• Click "Create Container".

• Go to MongoDB and click "Install" (Click "MongoDB" for more information).

• Click "Create"


• This will install an empty container. You will need to install, remove, and then install a new MongoDB.

• Choose the container and remove it.

• Choose "Create Container", and click "Install" to rebuild the MongoDB.

• In Command, enter "mongod --auth".

• Click "Advanced Settings".

• Go to "Network", enter a value for the MongoDB "port" number (for example: 37011).

• Go to "Shared Folder", and click "Add".

• In "Volume from host" choose the folder you established earlier (for example: Container > Mongo DB > db).

• In "Mount Point" enter "/data/db".

• In "Volume from host" choose the folder you established earlier (for example: Container > Mongo DB > configdb).


• In "Mount Point" enter "/data/configdb".

The purpose of adding these commands are for easy backup and modification

• Click "Create"

Step_2: Set up MongoDB account and permissions

• You may refer MongoDB DockerHub instructions for more information on setting access controls.

• Establish an account: In your MongoDB container, click "Terminal", enter "mongo admin", and click "OK".

• Enter the command "createUser({ user: 'input account', pwd: 'input password', roles: [ { role: "userAdminAnyDatabase", db: "admin" } ] }); ".

• Return to the MongoDB container, click "Terminal" and enter the command "mongo -u input account -p input password --authenticationDatabase admin".


• Click "OK".

• Enter the command "use database name" (for example: "use qiotdatabase").


• Enter the command "createUser({ user: "input account of DB ", pwd: "input password of DB", roles: [ { role: "dbOwner", db: "input the DB name you established previously"}]});"

(When you "establish another new account and password", it cannot be the same as the previously created user account (for example: "qiotduser")).

Step_3: Connect MongoDB to QIoT Suite Lite

• Open your IoT Application and click "Rule".


• In "storage", choose "mongodb" and pull it into Flow 1, and double click it.

• In Server, click the right button to add a new mongodb.

• Enter the below information:
  
  
  
  1. Host: 10.0.7.1 (Must be this IP)
  
  
  2. Port: The port number you set up earlier (for example: "37011").
  
  
  3. Database: The database name you set up earlier (for example: "qiotdatabase").
  
  
  4. Username: The username you set up earlier (for example: "qiotuser").
  
  
  5. Password: The password you set up earlier (for example: "qiotuser").
  
  
  6. Name: Enter a name (for example: "qiotdb").
  
  
  
  


• Click "Add".

• Enter a name in "Collection" (for example: temp).


• In "Operation", choose the operation you want. (More information, read the MongoDB website).


• Name: Enter a name.


• Click "Done".

• In "storage", choose "mongodb". In "function", choose "function". Then pull them into Flow 1.

• Double click "function", and enter the code you want to set up. (Refer to the "info" section on the right side for more information)


• Click "Done".

• Double click "mongodb", choose the server name you previously set up and enter the collection name you want (for example: temp).


• Name: Enter a name.


• Click "Done".

• After these settings, you can connect the function node and mongodb node together like below and click "Save".


• On the right side, you will see the value.
