[users@httpd] How do you implement mod_fcgid?
I'm in the process of installing Apache 2.4.3 with fast-cgi on a new
server. In the past we used mod_php but reading this user group that seems
to be a bit deprecated so I want to use mod_fcgid in this implementation.
I obtained the download from:
http://httpd.apache.org/download.cgi#mod_fcgid
and made it with apxs, and installed it as defined in the documentation into
../apache-2.4.3/modules. No errors were reported at any stage of this.
Then I added the following to httpd.conf:
LoadModule fcgid_module modules/mod_fcgid.so
Then I restarted Apache and get the following:
[root@prod03 conf]# ../bin/apachectl -k start
httpd: Syntax error on line 99 of /usr/apache-2.4.3/conf/httpd.conf: Cannot
load modules/mod_fcgid.so into server:
/usr/apache-2.4.3/modules/mod_fcgid.so: undefined symbol:
ap_unixd_setup_child
So I have an unresolved external reference that didn't get flagged by gcc
but where is it and what do I need to do to fix it?
Everything runs properly if I comment out the "LoadModule" line shown above
and I haven't done anything yet to actually define any CGI programmes
because it appears to me that mod_fcgid should start OK even with nothing
to do. (ie no AddHandler or SetHandler in the httpd.conf yet).
One documentation change that might be useful would be to say right at the
beginning that you should download mod_fcgid and then include it when
making Apache. That way it would always be there and properly linked in if
required.

John

I would be pleased to do that Nick but I have no experience with bugzilla.
If you can give me a short hint in how to go about it I will make the entry
immediately.

Good point. I guess the docs were written back in the days when
the unixd functionality was in core (2.2 and earlier). Ideally
we should abstract the API to avoid this issue, but a note in
the docs makes a good second-best.
If you enter it in bugzilla we'll have no excuse to forget it!
I was thinking about an instant update until I noted mod_fcgid
is still a separate subproject.

That worked, thanks Eric.
It was a positioning problem, mod_fcgid was ahead of mod_unixd in the
LoadModules list. I just moved it to the end of the list.
I don't like to criticise, but could the documentation for 2.4 be updated
to emphasize this requirement?
http://httpd.apache.org/mod_fcgid/mod/mod_fcgid.html
doesn't even mention mod_unixd.

Windows has a different security model, even if it is buried in the MPM.

Yes, mod_privileges supplements rather than replaces it.
Though it was some of the work on mod_privileges that led
to making system security a modularisable API, other than
through the MPM.

True, but right now we only have one mod_unixd model.
Which reminds me, your mod_privileges is its own module
rather than an ad-on to or replace for mod_unixd…

Allows alternative security models to be hooked in.
mod_unixd is the normal security model on unix-family
platforms, but you could switch it out for AN Other.
2.4 allows you to load MPMs dynamically, too.

I think there's just no special case for it, whereas it's natural for
mod_so with --enable-mods-shared=all.

What is the reasoning beind mod_unix being a shared

In 2.4, Load mod_unixd, and load it before mod_fcgid.

Re: [users@httpd] How do you implement mod_fcgid?
Posted by John Iliffe <jo...@iliffe.ca>.
I hate to re-post during the holiday season but in this case I am totally
out of any ideas.
The problem is that Apache is running correctly so far as I can see and I
want to add mod_fcgid, so I downloaded and compiled it (using apxs to
create a loadable module) and everything works fine. But when the
LoadModule command is executed the module doesn't load and issues the
following message:
httpd: Syntax error on line 99 of /usr/apache-2.4.3/conf/httpd.conf: Cannot
load modules/mod_fcgid.so into server:
/usr/apache-2.4.3/modules/mod_fcgid.so: undefined symbol:
ap_unixd_setup_child
Line 99 of httpd.conf is the request to load mod_fcgid
This is (obviously?) a programming error but my programming skills are
rather rudimentary and I have no idea how to approach this.
Can anyone help?
Details:
compiled using gcc on a Red Hat RHEL6.3 system. Apache-2.4.3.
Regards,
John
