(If you don’t have an account you must register first).•Open a console window and change the directory (cd) to the folder where you downloaded the tarball.•If there isn’t a user on the system dedicated to running the mysql daemon (typically mysql), you’ll need to create one. To do this, in the console, enter the following commands :

chown –R root /usr/local/mysqlchown –R mysql /usr/local/mysql/varchgrp –R mysql /usr/local/mysqlcp support-files/my-medium.cnf /etc/my.cnf

/usr/local/mysql/bin/mysqld_safe --user=mysql &

echo ‘/usr/local/mysql/bin/mysqld_safe --user=mysql &’ >> /etc/rc.local
