[users@httpd] apachectl and multiple daemons
I have the need to run multiple daemons off of the
same apache base install. Each daemon will have it's
own configuration file of course, but since they are
all configured pretty much the same (same modules etc)
I don't see a need to have several apache installs.
So, I'd have one install, i.e.
/usr/apache/xxxx
with multiple configs, i.e
/usr/apache/conf/httpd-host1.conf
/usr/apache/conf/httpd-host2.conf
/usr/apache/conf/httpd-host3.conf
Is there an "apachectl" script that allows for
multiple daemons to be managed? (start/stop/restart) ?

Re: [users@httpd] apachectl and multiple daemons
Posted by Richard de Vries <ri...@yahoo.com>.
Thanks to everyone who responded to my inquiry. I
indeed wanted process isolation. The server I am
currently building out needs to support several
development groups; all which require their own
webserver instance.
Initially I was wanting to go with IP based virtual
hosting, but this would not allow me to shutdown one
of the instances without affecting the others.
Additionally, a poorly written application in one of
the instances could negatively affect performance
and/or stability of the others as well. So, for this
particular environment I thought it'd be best to run
multiple daemons. (each instance using a unique IP
address).
Anyway, after reading the various replies, I decided
to make some minor modifications to "apachectl" to
support multiple daemons (instances). Now, when
running "apachectl stop|start|restart|graceful" it
will apply to all instances (useful as a /etc/init.d
startup script). However, if I want to
start/stop/restart a particular instance, I can do a
"apachectl start|stop|restart|graceful instance-name"
instead.
So, all is well right now :-)
Thanks again for all your replies!
Cheers,
Richard

Why not?

No, it sounds like he desires to have process isolation for different
contexts; which is fine. Many of the end users I support professionally
use this same approach. Different scoreboards, pid files, and logs and
listeners and you should be golden.

Sounds like you want to read up on virtual hosts.

I suppose you could split out the common part of each
httpd.conf file and include that into each apache
host-specific file you are using at start up.
What about ports though?
Is each apache going to listen on a different port?

In theory, theory and practice are the same;
In practice they are not.
