   export ORACLE_HOME=/opt/ora/instantclient_11_2
   export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME
   

   Create a file in /etc/ld.so.conf.d/oracle.conf that includes

   /opt/ora/instantclient_11_2
   

   Execute the following command

   sudo ldconfig

5. Create a symlink

   cd $ORACLE_HOME 
   ln -s libclntsh.so.11.1 libclntsh.so

     python setup.py build 
     python setup.py install
