This is weird. New server. cgi's don't execute outside the normal cgi-bin directory. The problem was showing up as problems with a nagios install. The nagios front page works, but the status pages, which are all cgi's, don't work.
I increased logging to debug in apache and I get:
[Tue Jan 09 14:53:21 2007] [error] [client 10.3.41.164] (13)Permission denied: exec of '/usr/lib/nagios/cgi/tac.cgi' f
ailed, referer: http://some.server.com/nagios/side.html
[Tue Jan 09 14:53:21 2007] [error] [client 10.3.41.164] Premature end of script headers: tac.cgi, referer: http://some.server.com/nagios/side.html
I tried some nagios config things, but then I took a simple hello world CGI, verified that it worked in the standard cgi-bin directory, and copied it into the script alias directory for nagios and it doesn't work.
Tried script alias directories in a few different partitions just to be sure. None of them worked.
Compiled a different version of apache, non-rpm, and installed in another directory, and that works,.but don't want to go that route.
Any ideas?
Some details below:
apache on rhel:
httpd-2.0.52-25.ent
Linux some.server.com 2.6.9-42.ELsmp #1 SMP Wed Jul 12 23:27:17 EDT 2006 i686 i686 i386 GNU/Linux
Nagios install wasn't working. conf.d/nagios.conf is:
##########
ScriptAlias /nagios/cgi-bin/ "/usr/lib/nagios/cgi/"
<Directory "/usr/lib/nagios/cgi/">
Options ExecCGI
AllowOverride None
Order allow,deny
Allow from all
AuthName "Nagios Access"
AuthType Basic
AuthUserFile /etc/nagios/htpasswd.users
Require valid-user
</Directory>
##########
Relevant cgi entry from the httpd.conf:
ScriptAlias /cgi-bin/ "/var/www/cgi-bin/"
#
# "/var/www/cgi-bin" should be changed to whatever your ScriptAliased
# CGI directory exists, if you have that configured.
#
<Directory "/var/www/cgi-bin">
AllowOverride None
Options None
Order allow,deny
Allow from all
</Directory>
