FATALERROR:Couldnotfind./bin/my_print_defaults
If you are using a binary release, you must run this script from
within the directory the archive extracted into. If you compiled
MySQL yourself you must run 'make install' first.

FATAL ERROR: Could not find ./bin/my_print_defaults
If you compiled from source, you need to run 'make install' to
copy the software into the correct location ready for operation.
If you are using a binary release, you must either be at the top
level of the extracted archive, or pass the --basedir option
pointing to that location.
