SUMMARY: increasing maxclients/hard server limit in apache

[Dan Simoes <dans@audifans.com>]

Apologies for the delayed summary.

The best answer from Mark Street:
First INSTALL the SRC.RPM, tweak the httpd.h file, then rebuild it.

rpm -ivh apache....src.rpm

go to /usr/src/redhat/SRC/ tweak it.

Then go to the /usr/src/redhat/SPEC dir and run

rpm -bb apache.spec    on the spec file.

BOOM, custom RPM in /usr/src/redhat/RPMS/   Consistency intact.

I also asked him if I could just tweak the spec file instead and he
replied:
I would either create a patch file of your own OR UNtar the tarball
found in 
SOURCES, go in tweak the source, tar it back up and then run rpm -bb on
the 
spec file.  Tweaking the spec file isn't going to do it I'm afraid....

>From the rpmbuild manpage in RedHat 8..... very similar to 7.3 rpm
command

I would check your rpm manpage for specifics.... or do a search on
google for 
rebuilding rpm from src source.
