It is not a system binary it is located under bin directory of your apache install location. On my system (apache compiled from source) for example is under /usr/local/apache2/bin/apxs. Use the full path to apxs when using it.
years ago I built a little website using mod_python. Recently I got a Raspberry pi and have been looking at redoing that website. My expectation is that I won't be able to make mod_python work but since it would be a lot less work to use it I thought I should take a look.The installation instructions require me to reference apxs. I could not find that on the installation on the RPi but looking at http://httpd.apache.org/docs/2.2/programs/apxs.html it still seems to exist. The instructions there say I should have it if I have mod_so.pi@raspberrypi ~ $ httpd -l-bash: httpd: command not foundpi@raspberrypi ~ $ apache2 -lCompiled in modules:core.cmod_log_config.cmod_logio.cmod_version.cworker.chttp_core.cmod_so.cpi@raspberrypi ~ $ apxs-bash: apxs: command not foundpi@raspberrypi ~ $ apachectl -v/usr/sbin/apachectl: 87: ulimit: error setting limit (Operation not permitted)Server version: Apache/2.2.22 (Debian)Server built: Jun 30 2012 06:18:51pi@raspberrypi ~ $I am very inexperienced at this and what experience I have is 7 or 8 years ago and my recollections are pretty fuzzy.
