MQTT server up and running in 7 simple steps

In this post I won't be talking about what MQTT server is why is and all, may be I'll write a different post for that. This post focuses on installing MQTT broker and getting it to work in 7 simple steps.

Step 1: sudo apt-get update
Step 2: sudo apt-get install mosquitto
Step 3: sudo apt-get install python-pip

Step 4: Install mosquitto module for python
> sudo python-pip install mosquitto

Step 5: Install mosquitto client
> sudo apt-get install mosquitto-clients

After executing above command you can start publisher and subscribe modules.
These publisher subscriber can use a topic and write/read data from it respectively.

Step 6: Start subscriber client
=> mosquitto_sub -h <hostname> -t <topicname> -v
> mosquitto_sub -h localhost -t testTopic -v

Step 7: Start publisher client
=> mosquitto_pub -h <hostname> -t <topicname> -m "<message>"
> mosquitto_pub -h localhost -t testTopic -m "Test Messages"

Please let me know if you find any errors while working with these steps.

How databasechangeloglock and databasechangelog table used by liquibase?

Liquibase takes care of executing the query on the database while maintaining the list of queries executed and also maintaining the locks over the tables simultaneously. The two tables that are used by the liquibase for this purpose are : Databasechangeloglock : This table have following columns ID | LOCKED| LOCKGRANTED | LOCKEDBY. This maintains the locks information granted to the user. The primary purpose of this table is to make sure that two machines don't attempt to modify the data at the same time. Databasechangelog : This table have following columns ID | AUTHOR | FILENAME | DATEEXECUTED | ORDEREXECUTED | EXECTYPE | MD5SUM | DESCRIPTION | COMMENTS | TAG | LIQUIBASE This table maintains the list of the statements that are executed on the database.
