In the example above, you can see the driver version I have is 17.7.Hello! I've RedHat Linux 6 Update 1 圆4 on VMware Player and MS SQL Server on real machine. You may need to identify the version number to check what features the specific version of the ODBC driver providers. You can simply inspect the file to learn the version number. The version of the ODBC driver installed on your Linux system is stored in the /etc/odbcinst.ini file.

Sudo apt-get install build-essential python3-dev python3-pip Appendix How to check the version of an ODBC driver installed in Ubuntu Linux If the error persists, try installing these as well: Then, you're likely missing the build dependencies in Linux. If during pip install pyodbc you get an error like this: error: command 'x86_64-linux-gnu-gcc' failed with exit status 1 I resolved this by adding this to the beginning of your config file at /etc/ssl/openssl.cnf openssl_conf = default_confĪnd then this to the end:

If you get the following error: TCP Provider: Error code 0x2746Ĭlient unable to establish connection Isql -v -k 'DSN=MY_DSN_NAME' Side note: Instead of defining the DSN in ~/.odbc.ini, you can also specify the entire connection string and pass it directly to -k parameter. Next check that you are able to connect via SQL.

odbcinst -q -d Setup a DSN (optional)Īdd an entry similar to below in your user ODBC file at ~/.odbc.ini ~/.odbc/ini Make sure the 'ODBC Driver 17 for SQL Server] or equivalent is installed. Odbcinst -q -d will give you installed ODBC driver. Odbcinst -j shows your OBDC configuration data: odbcinst -j This is case sensitive so would not work if your configuration was setup to use DOMAIN.NET.Įnter the password and you should be authenticated. Kinit replacing the username and DOMAIN.NET with your domain name. With all this setup, you should be able to get a ticket for kerberos.

Replace with actual values for your environment. Configure the name of your domain and the address for Kerberos server as depicted below. When krb5-user was installed, it created a file /etc/nf. You can type nslookup in your PowerShell or Command Prompt to discover the default AD server name and IP.Īdd these as an entry on your /etc/hosts file via sudo nano /etc/hosts Sudo apt-get install build-essential python3-dev python3-pip Setup Kerberos Configurationĭetermine your Kerberos/Active Directory authentication server. #You may need the following before doing pip install pyodbc Sudo apt-get install unixodbc unixodbc-dev -y These are required not only for UNIX ODBC but also for Kerberos client that is required to authenticate with Windows Active Directory. Sudo apt-get install -y unixodbc-dev Install Linux Dependencies # optional: for unixODBC development headers Sudo ACCEPT_EULA=Y apt-get install -y mssql-toolsĮcho 'export PATH='$PATH:/opt/mssql-tools/bin'' > ~/.bashrc Sudo ACCEPT_EULA=Y apt-get install -y msodbcsql17 #Choose only ONE of the following, corresponding to your OS versionĬurl > /etc/apt//mssql-release.list #Download appropriate package for the OS version The instructions on the Microsoft website are pretty straight forward, reproduced here: sudo su I also tried the FreeTDS driver which worked, but I didn't like the performance. Hence, I went through the trouble of using the Microsoft drivers.

There are other alternatives to use pyodbc with MS SQL but the performance of those drivers was not optimal for me. In addition I needed to authenticate using Windows credentials. The primary objective for me was to use pyodbc but a simple pip install pyodbc didn't work seamlessly for me. This post documents the steps required to connect to Microsoft SQL Server from a Ubuntu Linux environment using the Microsoft supplied ODBC Driver for SQL Server using Windows Authentication.
