if you are using a GUI then you are starting up in runlevel 5. so that means that you will want this proccess to start in run level 5. if your not using a GUI then you want runlevel 3. now your mysql and httpd (apache?) was installed by SuSE right? well if that is so then the scripts to start the programs are already there in /etc/rc.d/ . so depending on your default run level (the run level that the system is booted to) you will want to put a total of TWO simlinks in the rc?.d directory. lets assume that you are using a GUI and that your default run level is 5. so then that means that you will want to cd into /etc/init.d/rc5.d
once you have done that do an 'ls -l' youll see a bunch of simlinks and where they point to (files in /etc/init.d). for most of them there will be 2 simlinks pointing to the same place, one of the simlinks will be called S??servicename. and the same but with a K instead of an S. these mean start and kill. this is incase there is a different command to start and stop these processes. the number is the order that this will be started.

ok enough explanation, i dont know what the script in /etc/init.d/ is called for mysql, it might just be 'mysqld' but i dont know, you will have to find out that for your self. so this is howto set apache to run on boot, cd into /etc/init.d/rc5.d/
run the command:
ln -s /etc/init.d/apache /etc/init.d/rc5.d/S09apache

and then run the command:
ln -s /etc/init.d/apache /etc/init.d/rc5.d/K13apache

andyour done. restart your system to see if apache gets started successfully. now to be honest, im not really sure in what order it is to start certain services. im sure its a simple thing but i dont really know. so what i did was look in my rc3.d directory (3 because no GUI running on my server) and i looked for similar (daemon) services and looked at when they were started. SuSE already setup samba to run on boot aswell as sshd. ( i dont know why apache isnt set to run on boot by default) so the link to start sshd was S09, so i put apache as S09apache, for the kill script, i did the same thing, sshd was K13, so i put apache as K13apache. yes that is the same numberfor both. so keep track of what simlinks you put in there and if anything goes wrong just remove them. hope all that helps.

started

started(7)						 Miscellaneous Information Manual						started(7)

NAME

       started - event signalling that a job is running

SYNOPSIS

       started JOB=JOB INSTANCE=INSTANCE [ENV]...

DESCRIPTION

       The  started  event is generated by the Upstart init(8) daemon when an instance of a job has finished starting and is now running.  The JOB
       environment variable contains the job name, and the INSTANCE environment variable contains the instance name which will be empty  for  sin-
       gle-instance jobs.

       init(8)	emits this event as an informational signal, services and tasks started or stopped by this event will do so in parallel with other
       activity.  It is typically combined with the stopping(7) event by services declaring a dependency.

       Job configuration files may use the export stanza to export environment variables from their own environment into the started  event.   See
       init(5) for more details.

EXAMPLE

       A service that wishes to depend on another service might use:

	      start on started apache
	      stop on stopping apache

       A task that must be run after another task or service has been started might use:

	      start on started postgresql
