Since CentOS 7 MySQL was replaced with MariaDB by default. However in the standard repo package mysql-connector-odbc is version 5.2.25 that is incompatible with MariaDB.

You need to download and install correct mysql-connector-odbc package for MariaDB from here:

http://repo.mysql.com/yum/mysql-connectors-community/el/7/x86_64//mysql-connector-odbc-8.0.15-1.el7.x86_64.rpm

Install mysql-connector-odbc on CentOS 7 for MariaDB:
