I'm trying to get perl CGI programs to work from the cgi-bin (actually a sub-directory cgi-bin/various) and have set appropriate permissions using chmod 755. I'm currently testing using the simplest cgi program, you know the one: [....]
This has worked absolutely fine in the past, but now when I invoke it, either nothing appears in the browser (Mozilla Firefox) or I get "Internal Server Error" - any ideas please?
Is SELinux enabled? If so, the problem will show up in the audit logs:
ausearch -c httpd -m avc
In general, you'll want to
1. make sure the security context on the CGI script and the directory tree that contains it is httpd_sys_script_exec_t, and
2. make sure that no SELinux booleans are in the way, httpd_enable_cgi in particular:
getsebool httpd_enable_cgi
If it's set to "off," then you'll want to enable it:
setsebool httpd_enable_cgi=1
