    \n
  1. Download the Win32 installer from the below link (I couldn\u2019t successfully installed the CygWin version)
    \nhttps:\/\/mosquitto.org\/download\/<\/a><\/li>\n
  2. Once downloaded, install the package<\/li>\n
  3. During the start of the installation process it will show links from where some dependencies will have to be downloaded
    \n    \"\"<\/a><\/li>\n
  4. Copy\/Open the links<\/li>\n
  5. Once the installation finishes go to the websites opened in the previous step<\/li>\n
  6. Download the OpenSSL<\/em> installer and the pthreadVC2.dll<\/em><\/span> file<\/li>\n
  7. Install the OpenSSL<\/li>\n
  8. Copy the pthreadVC2<\/em>.dll<\/em><\/span> file to the directory where mosquitto executable has been installed. Normally C:\\Program Files (x86)\\mosquitto<\/em><\/span><\/li>\n
  9. Open folder where OpenSSL got installed (normally C:\\OpenSSL\\<\/em><\/span>) and open the lib<\/em> folder (normally C:\\OpenSSL\\lib<\/em><\/span>)<\/li>\n
  10. Copy ssleay32.lib<\/em><\/span> and libeay32.lib<\/em><\/span> into the folder where mosquitto executable has been installed.<\/li>\n
  11. Please note \u2013 while copying the files Windows might ask for giving Admin permission. Go ahead.<\/li>\n
  12. At this point Mosquitto should be ready to run————————————————————–<\/li>\n
  13. Now testing<\/strong> mosquitto<\/li>\n
  14. Open a Command Prompt<\/li>\n
  15. Goto the folder where mosquitto is installed<\/li>\n
  16. Give command mosquitto.exe -v -c mosquitto.conf<\/em><\/span><\/li>\n
  17. The server should now start listening on port 1883<\/li>\n
  18. Now open another Command Prompt<\/li>\n
  19. Give the command mosquitto_sub -h localhost -t channel1\/data1<\/em><\/span><\/li>\n
  20. Open a third Command Prompt and give the command mosquitto_pub -h localhost -t channel1\/data1 -m “test data”<\/em> <\/span><\/li>\n
  21. In the command prompt where we used mosquitto_sub <\/em>(step 18 and 19) will show the message \u201ctest data<\/span>\u201d sent from the third command prompt.<\/li>\n
  22. Reaching this point means mosquitto<\/em> is working fine———————————————-<\/li>\n
  23. To secure<\/strong> the transmission we can username and password authentication<\/li>\n
  24. Open a command prompt with Admin privileges<\/li>\n
  25. Goto the folder where Mosquitto is installed<\/li>\n
  26. Create a password file (for the first time only) using the command mosquitto_passwd.exe -c passfile.txt username<\/span><\/em><\/li>\n
  27. It will ask for password. Give the password and confirm the password<\/li>\n
  28. After this point further users can be added using the below command mosquitto_passwd.exe -b passfile.txt username password
    \n<\/span><\/em>Please note \u2013 this time we supplied the password also along with the username<\/span><\/span><\/li>\n
  29. Now edit the config file (mosquitto.conf<\/em><\/span> normally located in C:\\Program Files (x86)\\mosquitto<\/em><\/span>) to enforce only authenticated data transfers<\/li>\n
  30. Uncomment allow_anonymous<\/em><\/span> and set it false<\/span><\/li>\n
  31. Uncomment password_file<\/em><\/span> and put the password file name after it. It will look like password_file passfile.txt<\/em><\/span><\/li>\n
  32. Now onwards all sub and pub requests will have to be with username and password of a user whose details exists in the password file. Examples below\n
    mosquitto_pub -h localhost -t channel1\/data1 -m \"test data\" -u john -P johnpass \r\n\r\nmosquitto_sub -h localhost -t channel1\/data1 -u jane -P janepass<\/pre>\n<\/li>\n
  33. Access control can be done using a acl file or using mosquitto-auth-plug (https:\/\/github.com\/jpmens\/mosquitto-auth-plug<\/em><\/span>)<\/li>\n
  34. There should be a aclfile.example<\/em><\/span> inside your mqtt directory. If not then also no problem we will shortly see the contents of the file below.<\/li>\n
  35. Create a file with any name. Here we will use aclFile.txt<\/em><\/span><\/li>\n
  36. In the mosquitto.conf<\/em> <\/span>file uncomment acl_file<\/em><\/span> and put the name of your acl file after that. It will look something like acl_file aclFile.txt<\/em><\/span><\/li>\n
  37. Example content of aclFile.txt<\/span> as below\n
     # user jane given full permission to channel1\/data1 and only read permission to channel1\/data2\r\nuser jane\r\ntopic channel1\/data1\r\ntopic read channel1\/data2\r\n\r\n# user jane given full permission to both data1 and data2 channel\r\nuser john\r\ntopic channel1\/#<\/pre>\n<\/li>\n<\/ol>\n
    Please put in your suggestions in comment.<\/p>\n
