Strange problem with RH7

Hello ! I've installed RH7 in an x86. It comes with RPM's for PHP (4.01pl2 I think) and other modules (MySQL, IMAP...). This is the thing: - An easy RH7 install - I look for the modules after installation: - libphp4.so in modules - imap.so, mysql.so in /usr/lib/php4 All the binaries seem to be OK (I can't believe I didn't have to compile) I edit httpd.conf, it has already the lines for PHP under a <IfDefine HAVE_PHP> directive. So I make active: LoadModule php4_module modules/libphp4.so .. AddModule mod_php4.c .. AddType application/x-httpd-php .php4 .php3 .phtml .php AddType application/x-httpd-php-source .phps .. that already came with httpd.conf from RH7 Apache RPM's Life is beutiful ! Now, I go to /var/www/cgi-bin (because ScriptAlias /cgi-bin/ "/var/www/cgi-bin/") and I write a test .php file, for example the old <? phpinfo(); ?>. I give execute permissions to the file. Then I try to navigate to http://localhost/cgi-bin/test.php and I get an error 500: Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, root@localhost and inform them of the time the error occurred, and anything you might have done that may have caused the error. More information about this error may be available in the server error log. -------------------------------------------------------------------------------- Apache/1.3.12 Server at 192.168.10.24 Port 80 Arrrg! What's going on? All the binaries seem here, and httpd.conf seems OK. I am going to recompile it all again sooner or later anyway, but I'm afraid that after compilation I would leave everything more or less as it is now, so I'd rather know the reasons of the failure. Has anybody had a similar experience? Thanks in advance! F.J. Ortiz
