You can find all required information on running it from commandline at http://dev.mysql.com/.
If you're new to Linux and/or MySQL I would recommend the use of Webmin
. This program enables you to administer a lot of nifty stuff using your favourite webbrowser.
For example you can administer MySQL and Apache through Webmin. A great way to get to know those programs quickly, without all the hassle of command line commands.
