[gentoo-user] apache and the -D parameter

[gentoo-user] apache and the -D parameter

[Bill Kenworthy]

Hi,
	I am trying to set up mod_wsgi and apache in an LXC container.  apache
is ignoring all -D parameters on startup even though I can see them in
the startup script debug and they are being passed to apache according
to "ps aux".

apache -M does not show the modules in the loaded list.  If I remove the
"IfDefine" around the load command it works fine.

I am thinking that its something about the container .... but what?

What's the full "ifDefine" line?

What is your full APACHE2_OPTS line where you put the -D ?

standard gentoo VM on gentoo, with lxc-gentoo and stable apache and
mod_wsgi inside - its a new install for playing with radicale and wsgi

/etc/conf.d/apache2:
APACHE2_OPTS="-D DEFAULT_VHOST -D INFO -D SSL -D SSL_DEFAULT_VHOST -D
WSGI -D LANGUAGE -D SSL"

-D WSGI -D LANGUAGE -D SSL -d /usr/lib64/apache2 -f
/etc/apache2/httpd.conf -E /var/log/apache2/startuperror.log -k start

/etc/apache2/http.conf  ** note I have to comment out the alias because
the module isnt found unless I comment out the IfDefine

<IfDefine WSGI>
LoadModule wsgi_module modules/mod_wsgi.so
</IfDefine>
WSGIScriptAlias / /var/www/localhost/htdocs/hello.wsgi


Note that there are no modules from IfDefine here - these are all
outside the blocks. If I comment the IfDefines out it loads the module
and it all works fine.

Since these are showing the -D arguments being passed to the full path,
/usr/sbin/apache2, maybe you can try running,

  # /usr/sbin/apache2 -M

instead of just "apache2 -M"? Kind of a long shot, but I can't see
anything else wrong.

as expected, no difference :(

strace doesnt show anything useful - its reading the config files
including 70-mod_wsgi.conf but doesnt show anything else.

The only other thing I can think of would be to delete and re-type the
"-D" line in /etc/conf.d/apache2 and the <IfDefine> line in the apache
config. Maybe there's a non-printing space or something else evil in there.

The unstable apache-2.4 lets you "Define" variables within the config
files and not just on the command-line. If this is important, that might
get you up and running at the expense of satisfying your curiosity. Some
day we might replace all the -D stuff with "Define" anyway
(https://bugs.gentoo.org/show_bug.cgi?id=532710).
