Hi,
I tried prototyping this layout structure with multiple MPMs using sfw build
environment.
I modified sfw build scripts to build and install prefork, worker mpm binaries
under usr/apache2/bin directory.
First I built apr and apr-util libraries with --enable-threads option and then
built prefork followed by worker.
I have used different configure options for prefork and worker.
All the required modules are created during prefork mpm build (existing way).
For building worker mpm,
I did not include the extra module options used for prefork since only the
'httpd' binary from the worker build is copied to
usr/apache2/bin directory as httpd.worker. There is no need to build these
modules again.
All the modules that are generated during prefork build get installed under
usr/apache2/modules
(I have changed the directory name from "libexec" to "modules" which is more
intuitive).
I tested these 2 co-located mpms along with the prefork mpm (part of SXDE
installation) located under /usr/apache2.
First, I used torture script. Then I ran Apache Test suite. I have listed the
result of these runs.
Initially, some of the tests of Apache Test suite which passed for prefork mpm
failed (tests were hanging) for worker mpm.
It was failing in cgi module. By default, prefork mpm uses mod_cgi and worker
mpm uses mod_cgid. My build didn't have mod_cgid.
When I built and used cgid module, these tests passed for worker mpm and got
consistent results for co-located mpms and existing prefork mpm.
I have listed below, the configuration options used for building prefork and
mpm.
prefork:
./configure --prefix=/usr/apache2 \
--enable-layout=Solaris-Apache2 \
--enable-mods-shared=all \
--enable-so \
--enable-suexec \
--enable-proxy \
--enable-proxy-connect \
--enable-proxy-ftp \
--enable-proxy-http \
--enable-proxy-ajp \
--enable-proxy-balancer \
--enable-file-cache \
--enable-disk-cache \
--enable-cache \
--enable-mem-cache \
--enable-deflate \
--enable-cgi \
--enable-cgid \
--enable-ssl \
--with-ssl=/usr/sfw \
--with-apr=$(SRC)/cmd/apache2/httpd-prefork/$(VER)/srclib/apr \
--with-apr-util=$(SRC)/cmd/apache2/httpd-prefork/$(VER)/srclib/apr-util \
--with-mpm=prefork)
worker:
./configure --prefix=/usr/apache2 \
--enable-layout=Solaris-Apache2 \
--enable-mods-shared=all \
--enable-so \
--with-ssl=/usr/sfw \
--with-apr=$(SRC)/cmd/apache2/httpd-prefork/$(VER)/srclib/apr \
--with-apr-util=$(SRC)/cmd/apache2/httpd-prefork/$(VER)/srclib/apr-util \
--with-mpm=worker)
