[users@httpd] print() on closed filehandle error

[mk27 <ha...@intergate.com>]

...because I can't append a text file in the html directory.

Hi -- I just installed apache (from .rpm) on fedora 7 to learn perl CGI
with.  I notice that I can't overwrite or append anything existing in
/var/www/html from a cgi script in /var/www/cgi-bin, regardless of
permissions and ownership.  I presume this is blocked by apache.  What can I
do to reconfigure this?

As far as I know, permissions and ownerships are all that can be involved
here.  By default, apache is usually configured to handle requests as a
user with minimal privileges, e.g. "nobody" or "www".  By design this user
typically does not have any privileges to change files in /var/www/html
(or much of anywhere else) to minimize the damage that could be done if
a security bug in apache allowed the child process to be compromised.

Anyway, there are several ways you can handle this.

1) (most common) store your data in a database instead of in
the file system.

2) use suexec to run your CGI as another user

3) change the permissions on some files so the apache user can
modify them

4) change the user that apache runs as.
