azure ubuntu 16.04 VM can't connect to database on azure

Question

I trying connect to mysql db from VM , with python driver pymssql .

_connection = mysql.connect(host="xxxxxx.database.windows.net", user='xxxxxx@xxxxxx',
                                  password='xxxxx', database='xxxxxx')

But i get exeption like this

File "pymssql.pyx", line 641, in pymssql.connect (pymssql.c:10824) pymssql.OperationalError: (20002, b'DB-Lib error message 20002, severity 9:\\nAdaptive Server connection failed (my-xxxxx.database.windows.net:1433)\\n')

When I connecting to this database from my local pc all good.

PS I opened all ports for all protocols on my VM

Answer 1

Per my experience, Python pymssql package is depended on freetds-common package which will be installed when using sudo apt install python-pymssql command to install it.

And for Azure SQL Database, you need to set the tds version with 7.3 , so please refer to my anser for the other similar SO thread pymssql: Connection to the database only works sometimes to check whether the freetds has been install and what the tds version in the configuration file /etc/freetds/freetds.conf is.

Hope it helps.
