xsendfile using Apache+PHP

johndoe

Hi,
I tried to use xsendfile using a Apache+PHP application, but it did not work. I think mod_xsendfile is not installed. Can you confirm? There is a way to install?
Thanks

sean

johndoe correct, mod_xsendfile is not installed on our platform. I'll check with our sysadmins to see if we can get that installed and will follow up here when I have more info.

johndoe

sean Thanks! In the case, I would need it on opal5.

sean

johndoe ok, mod_xsendfile is now installed on opal5 and we'll roll it out platform-wide soon.

Hi Sean,
many thanks for your support and your decision to install mod_xsendfile.

But I have some problem getting it to work.

I added this line in .htaccess file:

XSendFile on

My PHP is like this:

<php

$filename = <absolute_file_path>;
$basename = basename($filename);

header("X-Sendfile: $filename");
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename=\"$basename\"");

But if I invoking script I only get a 0-byte file.

Is there any restriction on the path of the file to be served by mod_xsendfile?
I tried using a relative (to %{DOCUMENT_ROOT}) path, but still I didn't get any results.

Best regards

sean

johndoe is absolute_file_path at or below your app directory?

If it is not, then you'll need to use a private PHP-FPM stack for this with XSendFilePath /home/you/path/to/whatever set in the Apache VirtualHost.

The private stack is necessary because XSendFilePath is necessary when you need to serve files located outside of the web root, but that directive cannot be set in .htaccess. The private stack give you your own backend Apache instance with it's own httpd.conf which lets you set parameters that can't be set in .htaccess.

sean Yes, absolute_file_path is below my app directory.

sean

johndoe hmm, do you see any errors in ~/logs/apps/NAME_OF_APP/apache_error.txt?

(ignore the modsecurity mutex errors you might see there)

johndoe

sean Sorry, no errors in the log file.
I sent you a mail.

sean

johndoe The only way I was able to get this to work was by using a private PHP-FPM+Apache stack with the following additional config in httpd.conf:

Module config:

LoadModule xsendfile_module         /usr/lib64/httpd/modules/mod_xsendfile.so

VirtualHost config:

XSendFile on
XSendFilePath /home/user/apps/appname
