MySQL Default Password Issue

[Yawar Aziz]

Dear Professionals !!!

I am facing an issue while install MySQL 5.7.21-1 on CentOS 7.4. I am installing MySQL Community Server with its dependencies i.e. MySQL Community Clients, Libs & Common.

The problem is:
1) MySQL is not generating it's default password for root & /var/logs/mysqld.log is totally empty.
2) Let for instance, if I issue mysql_secure_installation command, even then it is not accepting any empty password (as at some helping forums, I read that sometimes there is no default password).
3) I also tried to generate "mysqladmin -u root password <new_password>" but even then the problem exists & I face the message "Error 1045 (28000): Access denied for user root using password YES" & "Error 1045 (28000): Access denied for user root using password No".

I also tried "skip-grant-privileges" but it's not working at all.

Strange thing is that I can easily install MySQL on RHEL 7.1 but CentOS is showing me problem. I have to install it on CentOS 7.4 so I seek your professional help.

Thank You
