Hello everybody,
I have a question:
how to let apache use a .php file to serve the corresponding http page and still prevent the same .php file from beeing downloadable with wget, by third parties ?
I guess this could involve file ownership, file permissions, php configuration and apache configuration.
Here is what I had before discovering that my php code was exposed:
I have Apache 2.4.37 installed on a centos 8 server, together with PHP 7.2.33
I have a hello world test.php php file in /var/www/html
Code: | $ls-l
-rw-r--r--. 1 root root 75 31 août 2020 test.php |
When
I do
1) go to siteurl/test.php with firefox,
I get the hello world message echoed normally.
The issue is that I am able to download the source code from another computer doing
2) Code: | wget 'siteurl/test.php' |
in the terminal
I feel it is not very safe, because database credentials can be in php files like config.php; and in general I want to hide my code, if possible.
I tried to solve the issue editing httpd.conf:
I added the following lines
Code: | <Files ~ "\.php$>
<RequireAll>
Require all denied
Require not user apache
</RequireAll>
</Files> |
(User and Group are set to apache)
I restarted httpd
Now
when I do 1),
I get the message
Quote: | Forbidden
You don't have pmission to access /test.php on this server. | "
when I do 2), I get a 403 error.
So the problem is not really solved,
I would like 1) to behave as before and 2) to behave as it is behaving right now.
Thank you for your help,
best.

how about just
<Files "config.php>
Require all denied
</Files>
or for multiple php files
<Files ~ "(config|install|preferences)\.php$>
Require all denied
</Files>
php will still be able to import those files, Apache will just not serve them up to the visitors. Visitors will get the 403 Forbidden. |

@glsmith Thank you for your answer.

There is a misunderstanding. When the Webserver is configured to interpret the php files they cannot be downloaded from the outside. |
