Linux version 3.10.0-327.28.2.el7.x86_64 (builder@kbuilder.dev.centos.org) (gcc version 4.8.3 20140911 (Red Hat 4.8.3-9) (GCC) ) #1 SMP Wed Aug 3 11:11:39 UTC 2016
My host name is not localhost, but root is always configured to 'localhost'. Also, I have 'root' user for linux (same name for mysql) - I have tried both password of as linux root user and blank password, but still got the same error.
I have re-installed the mysql, but also got the same error.
Please, help.
Thank you.
