[CentOS] MySQL in CentOS 5.2

Hi,

I've just installed MySQL (mysql.i386 5.0.45-7.el5) and lighty
(lighttpd.i386 1.4.19-1.el5.rf) to the CentOS 5.2, but could not find
mysql and lighttpd scripts in /etc/init.d. Also there is no
/usr/bin/mysql_install_db. Where can I find mysql and lighttpd scripts
for starting the processes in init.d?

Thank you.

Jim
