running redhat 4.0 with mysql installed over it.whenever i start my server i hv to manually start mysql. How i configure my linux so it automatically start mysql at system startup.

give me appropriate guide i am a new lerner.

man init
man inittab

you'll know what runlevel is

To auto-start something on boot, do the following:
create script, which accepts (preferably, it can accept only first variant) 1 argument, and only in three variants: start, stop, restart. Guess what should the script do. Then chmod a+x it and put it in /etc/rc.d/init.d . Now, if you link it with a name starting with 'S' from /etc/rc.d/rc<number>.d, it will be run with "start" on entering the runlevel, if first letter is 'K' - with "stop". Order of processing is the same as with simple 'ls -l'.

if you use the mysql standard package, simple, run as root and type

chkconfig --level 345 mysqld on

next time you start computer it will automatic turn on the mysqld.
