Don't do that; instead, have a separate RPM that just contains mod_jk
and maybe a script to install it on top of an existing Apache httpd RPM
install.
Forgive my skepticism, but are you building RPMs for a particular distro
or will there be yet another set of packaged versions of Tomcat-related
software out there that does not work properly.
No, I'm not building for a particular distribution. I'm building for a
specific configuration based on the way that we run things on my
company's servers. I have considered a separate RPM for the connector
but it seemed a bit silly for a single file especially when all our
servers run both Apache and Tomcat and the connector will be required on
all of them.
If you put the jk modules into your apache rpm, you couple the lifecycle
of those two together. So you need to build and deliver a new rpm
whenever at least one of apache httpd and of jk have a new version, you
want to deploy.
The release cycles of httpd and jk are very different from each other,
so you might want to consider unbundling and maybe not even installing
jk into the httpd directory, but in a different tree. That will make
your updates and rollbacks easier.
but I get an error that apxs cannot be found even though I give the
full path to apxs.
First thing that needs to work is ".../path/to/my/apxs -q PREFIX" (and
apxs needs to have execution permission).
Depending on the version of Apache httpd during configure we might do:
all:
apxs -q INCLUDEDIR
apxs -q CC
apxs -q CFLAGS
additionally for 2.x:
apxs -q APR_INCLUDEDIR
apxs -q APU_INCLUDEDIR
apxs -q EXTRA_CFLAGS
apxs -q EXTRA_CPPFLAGS
apxs -q exp_installbuilddir
apxs -q LIBTOOL
Stupid question: is that full path correct?
Absolutely. bash command line completion is a wonderful thing :-)
Note that since I'm building for purposes of packaging, I'm not
installing apache in its intended location but in a temporary
location. This is obviously the problem since if I do actually
install apache, the connector configure script works fine. Thing is,
I don't want to have install apache just to build the connector. Is
there any way to do this?
You will at least need installed header files and libraries. Otherwise
we can't compile respectively link. A module uses the httpd API and thus
needs the API description for compiles and during linking it checks, if
it could resolve symbols in the libs.
Ideally, the connector should be built on the machine that will be
running it. Is it acceptable to create an RPM that actually builds the
module instead of installing a previously-built binary? It takes only a
few seconds to build mod_jk from source. Since mod_jk requires Apache
httpd to be installed, installing such an RPM would require that apxs be
available in a known location, right?
I hadn't considered that. You're right that mod_jk doesn't take long to
build so building as part of the installation should not be a problem.
Thanks,
Dan.
