Hi, Rob: I forgot to mention that I have been using yum install. I have reinstalled the entire thing, put back all the packages, and then I went to /var and did a chmod -R 777 var, and then did a [root@localhost var]# chown -R apache:apache . Interestingly, I do not see anything different, and I still get this error that says my permission is denied. Here is my [root@localhost var]# ps awxu | grep -E 'apache|httpd'

Obviously, my last one has already changed the owner to apache already.Nevertheless, I am still denied even when I am now logged in as root. Is this anything with firewalls?

Hang on a minute: you're original message said the error was: Warning: chmod() [function.chmod]: Permission denied in /usr/local/apache/htdocs/file_linux.php on line 27 But you say you've re-installed, and done "chmod -R 777 var" and "chown -R apache:apache ." in /var A few things there: When you are changing permissions and ownerships on such a large scale, you should always use absolute paths to be sure you are doing the right thing - like "chmod -R 777 /var" and "chown -R apache:apache /var" Next, changing permission and ownership recursively on something like /var is likely to wreck your system in weird and wonderful ways, and is pretty difficult to undo - you might be looking at a total OS reinstall here (once you've solved your Apache problems) Finally, the error message refers to a file in /usr/local/apache/htdocs, but you then are changing permissions in /var - where is your web root?! It looks like your PHP code has the /usr/local/apache/htdocs path hard-coded, when your web files are actually in /var/something... I forgot to mention that I use Fedora on a Linux machine. I used yum install apache and yum install php to install my packages. Therefore, I don't have a /usr/local/apache/htdocs folder. The web root is now /var/www/html, which originally I do have /usr/local/apache/htdocs that I configured during previous installations. This is not there anymore after my reinstallations since yesterday. Do I really have to reinstall the entire Fedora? I hate to say that my scripts worked fine BEFORE yesterday until the power went out and nothing went right after I have restarted the entire system. Alice

You don't *have* to reinstall Fedora (yet) - that was just a warning that changing ownership and permissions on /var might cause some problems later... So the question is, does the error message say that it cannot change permissions on /usr/local/apache/htdocs/file_linux.php or /var/www/html/file_linux.php ? And does your PHP script have the correct path? The original problem may just have been that the /usr/local file system was mounted read-only after the power outage (perhaps due to some disk corruption caused by the failure?). Since then you have reinstalled apache, but possibly not in the place your PHP script expects it to be. That would be my first thing to check... -- Peter Ford, Developer phone: 01580 893333 fax: 01580 893399 Justcroft International Ltd. www.justcroft.com Justcroft House, High Street, Staplehurst, Kent TN12 0AH United Kingdom Registered in England and Wales: 2297906 Registered office: Stag Gates House, 63/64 The Avenue, Southampton SO17 1XS
