> bin/mysqld_safe --user=mysql &

Or install it with rpm in fcX with:

> yum groupinstall mysql
> /etc/init.d/mysqld restart

Setting up the initlevel

Copy the mysql.server file into /etc/init.d and then create symbolic links to it in /etc/rc3.d and /etc/rc0.d. Finally, before rebooting, create a symbolic link from the Mysql root folder into /usr/local/mysql.

> cat support-files/mysql.server | head
# MySQL daemon start/stop script.

# Usually this is put in /etc/init.d (at least on machines SYSV R4 based
# systems) and linked to /etc/rc3.d/S99mysql and /etc/rc0.d/K01mysql.
# When this is done the mysql server will be started when the machine is
# started and shut down when the systems goes down.

...

# If you install MySQL on some other places than /usr/local/mysql, then you
# have to do one of the following things for this script to work:
#
# - Run this script from within the MySQL installation directory
# - Create a /etc/my.cnf file with the following information:
#   [mysqld]
#   basedir=<path-to-mysql-installation-directory>
# - Add the above to any other configuration file (for example ~/.my.ini)
#   and copy my_print_defaults to /usr/bin
# - Add the path to the mysql-installation-directory to the basedir variable
#   below.
#
# If you want to affect other MySQL variables, you should make your changes
# in the /etc/my.cnf, ~/.my.cnf or other MySQL configuration files.

# If you change base dir, you must also change datadir. These may get
# overwritten by settings in the MySQL configuration files.

basedir=/home/guillaume/Software/las/mysql-standard-5.0.27-linux-i686
datadir=/home/guillaume/Software/las/mysql-standard-5.0.27-linux-i686/data
