mysql on redhat9

[Stephen Camilleri]

I was running mysql 0.8.12 on a Redhat9 installation. After I rebooted
machine I lost access to mysql as root user.
 
Maybe its a stupid question but I'm new at this... Did I have to do
anything 'persistent' to db before rebooting. I am testing mysqld with
ser (SIP Proxy)
