MQTT Broker in Alibaba Cloud – Secure hosting

By |September 19th, 2018|


Alibaba is the most used cloud hosting provider in China.  This article provides a step by step procedure to set up the MQTT Broker in Alibaba cloud.  Bevywise MQTT Broker just needed a Ubuntu instance to host the broker.

Setting up the Alibaba Cloud for MQTT Broker:

  1. Select the Elastic Compute Service and create Ubuntu instance with minimum 1 CPU, 2GB RAM, 40 GB Disk with  Intel Xeon processor.
  2. After creating the instance, reset the password for ssh login.
  3. Create a inbound and outbound rule to ssh
    • To create outbound and inbound rule, expand “Network and  Security” and select “Security Group”.
    • In that page select “Add Rule”, it lead to Ingress and Outbound  page.
    • Click “Add Security Button” on the top right corner, it lead  to “Add Security Group Rule“.
    • In that Window select “Protocol type” as SSH and  “Authorization Objects” as 0.0.0.0/0 for access the Port  from any where or give specific IP address from which you  access SSH.
    • Do allow inbound flow of traffic for the following ports as well – 1883, 8080, 8081, 443 & 8883 
  4. Alibaba instance can be easily used via a remote connection from Windows, Ubuntu and MAC.
  5. Remote Connection from Windows:
    1. Download PuTTY fromhttp://www.chiark.greenend.org.uk/~sgtatham/putty/ or from other PuTTY download source. The “putty.exe” download is good for basic SSH.
    2. Save the download to your C:\WINDOWS folder.
    3. If you want to make a link to PuTTY on your desktop:
      1. Open the C:\WINDOWS folder in Windows Explorer.
      2. Right click on the putty.exe file and select Send To > Desktop
    4. Double-click on the putty.exe program or the desktop shortcut to  launch the application.
    5. Enter your connection settings:
      MQTT Broker Upload Putty settings

      Host Name: <Alibaba Public IP address>

      1. Port: 22 (leave as default
      2. Connection Type: SSH (leave as default)
    6. Click Open to start the SSH session.
    7. If this is your first time connecting to the server from this computer, you will see the following output. Accept the connection by clicking Yes.
      Login confirmation
    8. Once the SSH Connection is open, you should see a terminal prompt  asking for your username:
      login as: Connect with your SSH user of choice.Next, enter your  password.
    9. Please note that you will NOT see your cursor moving, or any  characters typed (such as ******), when typing your password. This is     a standard PuTTY security feature. Hit enter.
      Using keyboard-interactive authentication.
      Password:
    10. You are now logged into your server with SSH.
  6. Remote login from Liunx and MAC:
    • Open terminal and type ” [email protected]<public Alibaba IP>” and hit enter.
    • Type the password which you have reset in Step2.
    • You are now logged into your server with SSH.

You must have created an Ubuntu server by now and might have tested access to the server from Windows or  Linux or MAC. The next step is to transfer MQTT Broker to Alibaba.

Download the MQTT Broker

The MQTT Broker can be downloaded using the following button. The MQTT Broker has a 30 day trial version which supports upto 100 devices. You have to download the Ubuntu Version

FREE MQTT Broker

Transfer MQTT Broker to Alibaba

For Windows:

  1. Download the PSCP utility from PuTTy.org by clicking the file  name link and saving it to your computer.
  2. The PuTTY SCP (PSCP) client does not require installation in  Windows, but runs directly from a Command Promptwindow.  Move the download PSCP.exe file to the any location and note  the location
  3. Set the Environment Path for the PSCP.exe file.
  4. Open the Command Prompt window.
  5. Type “pscp <BevywiseMQTTRoute zip path> [email protected]<serverpublicIP>:/home/” and hit enter. The zip file will be automatically copy to the /home  location of Alibaba ubunut instance

For Linux & Mac:

  1. 1. Open terminal and type below command .
    “scp <BevywiseMQTTRoute zip path> [email protected]<serverpublicIP>:/home/”
  2.  Zip file will be saved in the /home location of Alibaba Ubuntu  instance.

Starting MQTT Broker in Alibaba Cloud

It is very easy to set up MQTT Broker in Alibaba cloud. You can simply follow these steps to achieve it.

  1. Login to the Alibaba Ubuntu server via SSH and go to /home location via           “cd /home” command
  2. Type “unzip Bevywise_MQTT_Route_Linux.zip” and hit enter. Now MQTTBroker file will be extract in /home location under the Bevywise folder.
  3. Go to the file Bevywise by below command and hit enter.
    “cd Bevywise/MQTTRoute/bin”
  4. Open the data_store.conf file which is inside the conf folder.

    “vim /home/Bevywise/MQTTRoute/conf/data_store.conf”

    In that file change follow conf and save the file:

    DB_SERVER = MYSQL and give MySQL username and password 

    MYSQL_USER = <username>

    MYSQL_PASSWORD = <password>

  5. Run the Bevywise MQTT broker using the following command. It is advisible to run the Broker in the background mode to make sure the broker runs even after you close the terminal.
    “sh runbroker.sh”

Run MQTT Broker in Alibaba as a Service

If you don’t run MQTT Broker in Alibaba cloud as a service, then it will quit when you close your ssh session. So make sure you run the MQTT Broker as a service.

To run the MQTTBroker as service we need the Monit version 5.25 and it cannot be installed using the apt-get. The procedure to set up the monit is as follows. This application will ensure that the service will be started again when the server gets restarted.

  • Download the Monit for linux X64 or X86 based on your servers.
  • Extract the archive using tar -xzf < downloaded file >
  • Go to monit-5.25.2/bin
  • copy monit to /usr/bin folder – sudo cp monit /usr/bin
  • Go to monit-5.25.2/conf
  • copy the monitrc file to “/etc/” using below command – sudo cp monitrc /etc/
  • Modify the monit conf file. Uncomment the following lines in /etc/monitrc file.  use sudo vi /etc/monitrc. Change the username and password as per your  need.
    set httpd port 2812 and
           use address localhost # only accept connection from localhost  (drop if you use M/Monit)
           allow localhost # allow localhost to connect to the server and
           allow admin:monit # require user ‘admin’ with password ‘monit’ 
  • Add the following at the end of the /etc/monitrc file
    check process MQTTRoute with pidfile < path to Bevywise/MQTTRoute  >/Broker.pid
         start program = “< path to Bevywise/MQTTRoute >/bin/runbroker.sh”  with timeout 2 seconds
        stop program = “< path to Bevywise/MQTTRoute >/bin/stopbroker.sh”  with timeout 2 seconds
  • To reload the confirmation changes, run sudo monit reload
  • Add MQTTRoute process to monitoring sudo monit start MQTTRoute

MQTTRoute is a perfect middleware and fastest broker to be used for collecting data from your IoT edge devices and store and analyse it the way you needed.  Tableau is a cool BI tool that will help you analyse the data in all dimensions.  MQTT Broker Tableau integration will help you store all your data in the format you needed into the Tableau for a perfect data analysis. This blog helps you visualize data of MQTT Broker with Tableau by connecting it to MySQL or MongoDB.

MQTT Broker Tableau Integration using MySQL

 Changes to be done in MQTT Broker: 

  1. Open the Conf folder(Bevywise/MQTTRoute/conf)
  2. Change the DB Server to MySQL
  3. Give the MySQL Password in “MySQL Password =”
  4. Save the File
  5. Check that the MySQL is running on 3306 Port.
  6. Start the MQTT Broker using sh runbroker.sh inside the bin/ folder.
  7. Next connect the client and verify that the “bevywise” DB is created in MySQL.

To Verify the DB is Created or not in MySQL:

  1. Login to MySQL by the command “mysql -u<username> -p<password>”
  2. Next type “show databases;” command to view the created DB.
  3. In Output, you can see “bevywise” db is created.

Connect Tableau via MySQL ODBC Connector :

Tableau will use MySQL ODBC connector driver to talk to the MySQL. You might already have the required driver installed on your computer. If the driver is not available in your computer, Tableau displays a message in the connection dialog box with a link to the Driver Download page where you can find driver links and installation instructions. Click the “Data Source” drop down box and Select “MySQL”. Next choose OS & Bit Version and Install the driver.

Make the connection and set up the Tableau:

1.Start Tableau and under Connect, select MySQL. Then do the following:

  • Enter the name of the server that hosts the database.(Give “localhost” if MySQL is running in the same machine)
  • Enter the user name and password.
  • Select Sign In.

2.On the data source page, do the following:

  • From the Database drop-down list, select a database or use the text box to search for a database by name.
  • Under Table, select a table or use the text box to search for a table by name.
  • Drag the table to the canvas, and then select the sheet tab to start your analysis.

MQTT Broker Tableau Integration via MongoDB

Configuring MQTT Broker:

  1. Please download and install MonogDB Plugin for Bevywise MQTT Broker.
  2. Follo the steps in Readme.md file to configure and setup the MonogDB Plugin.

Next use the “bevywise” database by the command ” use bevywise

Type the below query to create a username and password for the DB

db.createUser(

{

  user: “<Username>”,

  pwd: “<Password>”,

roles: [ { role: “userAdminAnyDatabase”, db: “bevywise” } ]

  }

)

Re-start and login to the MongoDB by the command

mongo –port 27017 -u “myUserAdmin” -p “abc123” –authenticationDatabase “bevywise”

For more reference refer the Enable Auth link
