Those error messages are from the python connector. Probably not a MySQL problem at all. However the error code gives at least a clue:

~ $perror 13
OS error code 13: Permission denied

The Python process got a "permission denied" error when trying to access MySQL. This could be some SElinux or firewalling problem. Check the syslog for related messages.

I also suggest you review the configuration of that Python stuff. If the MySQL server runs on the same machine, it's recommended to connect through the UNIX socket (something like /var/lib/mysql/mysql.sock) instead of using the TCP stack (via 127.0.0.1) Received on Fri Feb 03 2017 - 12:39:51 CET
