Hi Will,
I understand all of the centos-package-only rhetoric but am still
curious about a technical answer to my specific technical question.
I appreciate all of the helpful pointers you've copied in from the site
-but in this case the question is more important than enforcing the
packaging paradigm -and I support the project's views on that and have
seen them many times.
To wit, Community Enterprise OS is used outside of this context all of
the time -in this case for a highly scientific purpose related to
optimizing chip yields -with, (gasp), things compiled from source which
are (sigh of relief) eventually turned into nifty RPM files that can be
shared/modified/perfected by the community by the brilliant likes of the
centos package maintainers at their noble and highly revered discretion.
"To do the science we must do the work". So apologies for the "outside
the box" moment. We are doing this work on 60+ 64-bit servers, all of
whom have apache from source because we had our own needs to answer to
and this OS was the closest match to the need to make a javagroups
application cluster, which it does very very well.
If anyone knows, much appreciated, -you can just email me 'off-list'. I
emailed the mod_sslusers list so hopefull that'll get a nice clear
answer.
And just to be really clear, no negative attitude here or anything,
-just looking for a community assist on an important question. thanx!
OK, cool. The reason for the potted "Use RPMS" response was that the
vast majority of people asking "how to do X/Y/Z" with the source tend
not to understand what they're doing or why, they're just following a
how-to or FAQ that doesn't take a packaging system into consideration.
And people who do "get it" tend to just RTFM or Google it :)
To enable SSL support in Apache at build time you need to pass the
'./configure' a couple of options and the paths to some SSL libraries,
if those have been built and installed outside the packaging system
too.
--enable-shared=ssl \
--enable-module=ssl \
The output from
# $path_to_apache_source/configure --help
is copious and useful. As are the INSTALL/README files included in
that source.
Assuming your Apache was configured then built with modular support
(mod_so.c) then you can enable additional functionality after-the-fact
using 'apxs'. SSL support *may* be so tied into the Apache build that
'apxs' won't suffice but I'd guess you'll be OK.
Will.

oh great, so if you ever run across a centos server and the owner says
"it was made from source, can you please fix it", -or are just plain
curious about what I did to fix this [how to uninstall apache 2.0.58
made from source], you just have to do two commands to remove the apache
compiled from source, like this:
rm -rf /usr/local/apache
rm /etc/rc.d/init/d/httpd
the first rm command recursively forcibly removes the apache dirs and
files under /usr/local/
the second rm comand will delete the symlink from
/usr/local/apache/bin/apachectl to /etc/rc.d/init.d/httpd if it exists
you can then effectively revert to the centos method of
yum install httpd
or
yum groupinstall "Web Server"
and skip merrily along your webified path through the elysian fields of
networked information.
