Hello !

i use FC8 and i want some services like HTTPD and NAMED to start at the start of the system , how to create a script to do that ...
thanks

chkconfig <service> on

You usually don't - you use a supported release of fedora instead. I understand f12 is current and f11 is still supported. f8 is unsupported now, so you can expect increasing difficulty maintaining it. If a 16 month turnaround is too fast for you, consider RHEL, CentOS or Ubuntu LTS.

I'm guessing you want to run the box as a web and name server? That would be apache and bind?

Note: I'm just guessing that FC8 means "fedora 8".

what i want is so simple, i want a service to be started at the start of the system, what ever bind or apache or squid ...
HTTPD just an example it doesnt start automatically i have every boot to type : service httpd start

i want that to be uatomatically

Running the command will configure init to start httpd automatically.

thanks,
and the script to be start at the start of the system

No, he means that you type
once and that from then on, httpd will start automatically.

But that doesn't really answer your question, because you said

and that's the problem, because there are multiple possibilities for starting things up.

This is actually a very complicated subject. You can start things in /etc/inittab. For the moment I'll ignore distros that don't use inittab or are in transition ( Ubuntu in the Linux world is transitioning to Upstart, BSD and Mac OS never used inittab ).

You can also start things by putting scripts into the directories that existing inittab entries run through. Some of these scripts already exist in an unactivated state and that's what "chkconfig" does on systems that support it - it makes links into appropriate directories to scripts and those scripts will be run at startup because inittab runs a script that looks for those and runs.

So, for example, inittab runs /etc/rc and passes it a runlevel argument. If that's 5, scripts in /etc/rc5.d are run. AS I said, :"chkconfig" just activates these:

Scripts that begin with K are "kill scripts" - they stop the service. "S" scripts start it. Actually they are the same script (a link to /etc/rc.d/init.d/httpd) , but the /etc/rc script calls "S" scripts with "start" as an argument and "K" scripts get passed "stop". If you look at script, you'll see how it parses the arguments.


You could also just add entries to a script that always runs. On almost all systems, there's a "/etc/rc.local" script. You COULD add "service httpd start" to that or "/etc/rc.d/init.d/httpd start" to /etc/rc.local, but the advantages of letting chkconfig and the rc scripts handle it should be obvious.

Another place for daemons is in /etc/xinted.d but this is long enough already.

I put additional info (like how to add your own script to chkconfig) at http://aplawrence.com/Basics/unix-st...scripts-1.html

I guess on FC8 there is a command - ntsysv - that you can use to control the service start up for all services at glance.

In post #2, the first line answers your question :)

It is pretty unusual for someone to want to know how to generically start a service without an actual application in mind - it is the sort of question that gets asked as an exercise or assessment - in an exam or as homework.

As you have found out, what you have asked is not, in fact, so simple as it appears - there are many possible replies. A context helps us figure out the kind of answer which is likely to help you.

for more information - see the man pages for:

chkconfig
serviceconf
and, yes,
ntsysv
