After updating mysql with yum to 5.6 I am getting such an error message when trying to run mysql

[root@host rpm]# mysql_upgrade
Looking for 'mysql' as: mysql
Looking for 'mysqlcheck' as: mysqlcheck
Error: Failed while fetching Server version! Could be due to unauthorized access.
FATAL ERROR: Upgrade failed

I also tried

mysql_upgrade -u root -p

and the result is the same.

  • How did you installed new and old MySQL (by using (yum or apt-get) or compressed file.)? – Ahmad Abuhasna Dec 16 '15 at 10:01
  • With yum. I suspect the update went wrong somewhere... I scrapped the entire virtual server, and rebuilt from scratch with the latest mysql, so the issue is gone. – giorgio79 Dec 16 '15 at 11:22

Please check if you are using correct root password. You can also use another login which has all privileges. Check it by logging to mysql:

After checking return to server try again mysql_upgrade
