Thanks for a quick reply!
I got a little further ahead, but still some problem remains.
I gave a command "/etc/rc.d/bin/mysqld -V", but I got a message "usage: /etc/rc.d/bin/mysqld up|down". Well, this is how I learned to stop and restart mysql, but still I don't know how to give a parameter to "mysqld".
"man mysqld" shows a lot of parameters, including the one (--default-character-set) which I want to use, but the response to my command suggests that only parameters "up" and "down" are acceptable. There's obviously something I don't quite grasp. Will you please enlighten me still a bit more
I fiddled some more with mysqld -command and I managed to do what I wanted!
