Sorry but, did I paste enough config files ?

Is there a way to check if the config is correctly "set" ?

Start by posting more of your configuration.

Adnan,

For the following to work you need headers module installed:

location ~ /(?<filename>(?!/).+\.mp3)$ {
types {
application/octet-stream mp3;
}
add_header Content-Disposition "attachment;
filename=\"$filename\"";
}

Kind regards,

@Cliff: I didn't find them :/ I've asked the CPanel module devs to tell me where are the vhosts. Actually, I think nginx is just a "proxy" to apache, but it's strange... It means apache is still running and .htaccess working... I'll tell you as soon as I have the response.

Also, you mention stuff in "custom", but I don't see where any of the
config you pasted includes a "custom" config.

My custom conf is in "/custom/". This is what I had before @locojohn tip.

root@shadow [/etc/cpnginx/custom]# cat mega-sound.be
location ~* \.mp3$ {
types {
application/octet-stream mp3;
}
}

For the following to work you need headers module installed:

Sorry but, what do you mean? Isn't "headers" a standard module ? How to check the compiled modules please ?

location ~ /(?<filename>(?!/).+\.mp3)$ {
types {
application/octet-stream mp3;
}
add_header Content-Disposition "attachment; filename=\"$filename\"";
}

This is my new custom config file. Nothing changed. Still audio/mpeg :/

Adnan, if it doesn't set the "Content-Disposition" header as per my
example, then it doesn't match the location in which this header is set.
It is likely that some other location has preference and so the code I
provided will never be triggered. Look into your nginx config more
closely. Also, check the error log, do you get any warnings?
Sometimes, PCRE library may throw a warning, maybe you can use
alternative location syntax compatible with an older version of PCRE:

...
location ~ /(?P<filename>(?!/).+\.mp3)$ {
...

Are your mp3 links static at all?

Unfortunately, it doesn't work.

Here is a link example: http://www.mega-sound.be/adata/428.mp3

Actually, the first thing i've tried, is:

types {
application/octet-stream mp3;
}

The only failure, is that with that, even CSS are downloaded (so, webste screwed up), and now I know that I HAVE to use "location".

I gave you an example link, the mp3 are in: /home/customer/www/adata/428.mp3, they're directly downloadable...

And poor me, the dev of CPNginx plugin told me that they don't support custom config, so they won't help me T_T

I'm fairly certain this is exactly what is happening. Either solution
should work fine, but only if the location is properly matched.

Again, it's not the preferred solution, but directly editing mime.types
would probably work.

Mmmh...

Ok. I see, maybe there will never be any match, as there is only "proxy_redirect" in vhosts;

########### Vhost configuration of mega-sound.be

server_name mega-sound.be www.mega-sound.be;
access_log /usr/local/apache/domlogs/mega-sound.be;
proxy_redirect http://www.mega-sound.be:8888 http://www.mega-sound.be;
proxy_redirect http://mega-sound.be:8888 http://mega-sound.be;
proxy_redirect http://mega-sound.be:8888 http://mega-sound.be;
include "/etc/cpnginx/custom/mega-sound.be";

Apache is still listening on :8888

Is there a chance with this conf, to match any "location" as there is no "document_root" or equivalent ?

I mean, location is system based or URL based?

If it's system, I don't know. If it's URL based, there should be a match since the first test.

Isn't it ?

Hi,

Finally I need your help :/

The "CPNginx" devs have a website with a ticket support system, but they're telling me that they don't support custom configuration...

I've told them I need their help because they know how they built their module and how they made it work, they still just answer "You need to do it by yourself"...

What can I do T_T ?

Hey everybody !

Here are some news.

I've compiled nginx with HttpHeadersMoreModule, to add custom headers in order to see if the location is or isn't matched.

Here is what I tried:

URL: http://www.mega-sound.be/adata/428.mp3

Custom config file:

root@shadow [/etc/cpnginx/custom]# cat mega-sound.be
location ~* \.mp3$ {
more_set_headers 'X-MyHeader: .mp3';
}

location /adata {
more_set_headers 'X-MyHeader: adata';
}

more_set_headers 'X-MyMasterHeader: set';

The headers sent:

Hi there,

Read http://nginx.org/en/docs/http/request_processing.html

Look in your config file. Be aware of "include" directives. Look in
every server{} block. Look at "listen" and "server_name" directives in
each server{} block.

Identify which one server{} block is being used to handle this request.

Post the config for that server{}.

(If you can additionally identify which one location{} block within
that server{} block is being used for this request, then you could
limit what you post to: the server{} block outside of all location{}s,
plus the content of that one location{}. But that's probably more work
than is necessary.)

If you can enable the debug log (will probably require rebuilding
nginx), then you will see lots of information about what nginx thinks
is happening.

But posting the relevant part of the config file is the best way to make
it easy for people help you.

I knew that location are matched 1 time but I didn't noticed the |mp3 T_T

Thank you very much, I'm understanding more and more nginx.

I think it's done, I just have to deal with the CPanel NGinx module devs to change include place (in order to avoid this case another time).

Then, here is the vhost:

Great, this shows why things are working the way they are.

location ~* ^.+.(jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|iso|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|mp3|ogv|ogg|flv|swf|mpeg|mpg|mpeg4|mp4|avi|wmv|js|css)$ {

This is the first regex location that matches mp3 urls, so this is the
one that will be used.

For what I think you want to do, you should remove "|mp3" from up there,
and then have the separate "~* \.mp3$" location later.

expires 24h;
root /home/megasoun/public_html;
error_page 404 = @apache;
access_log /usr/local/apache/domlogs/mega-sound.be;
log_not_found off;

Based on the rest of the config, you can probably move some of those to
"outside all locations", so that they will be inherited into all locations
that don't otherwise set them.

<snippage>
location / {
proxy_pass http://87.98.132.48:8888/;
}

location @apache {
proxy_pass http://87.98.132.48:8888;
}

include "/etc/cpnginx/custom/mega-sound.be";
}

root@shadow [/usr/local/nginx/conf]# cat /etc/cpnginx/custom/mega-sound.be

As above, because this is included last in the main file, the mp3 location
here can never match.

So if you remove the "|mp3" up there, then this one will match:

location ~* \.mp3$ {
more_set_headers 'X-MyHeader: .mp3';

and now you can set your types, or do whatever else is needed, and have
it take effect.

(If your default or server-level "root" is not correct for this location,
you'll want to set that in here too.)

Because of the nginx location matching rules, this next location won't
be used for /adata/123.mp3, but will be used for /adata/123.html. You can
test that by putting a file of the right name in the right ("root"/adata)
directory, and seeing the X- header appearing.

location /adata {
more_set_headers 'X-MyHeader: adata';
}

And these two are outside of all locations, so apply to everything that
does not override them.

more_set_headers 'X-MyMasterHeader: set';
more_set_headers 'X-My2Header: $request_uri';

Here is the HTTP Headers for the root URL (www.mega-sound.be):

This is expected to be proxy_pass'ed to port 8888, and you can see that
your "all" more_set_headers directives did apply.

HTTP/1.1 200 OK
X-MyMasterHeader: set
X-My2Header: /

Here is the headers for an MP3 (http://www.mega-sound.be/adata/362.mp3):

This would match your original long location, so will be the file
/home/megasoun/public_html/adata/362.mp3 if it exists, and proxied to
port 8888 if it doesn't. Again, your "all" more_set_headers apply.

HTTP/1.1 200 OK
Content-Type: audio/mpeg
X-MyMasterHeader: set
X-My2Heade: /adata/362.mp3

If you remove "|mp3" from the first location; or just "include" this file
at the top instead of the bottom of the server{} block, then your custom
mp3 location would apply; and you should see your extra configuration
being used. (Without "root" set right, though, you may just end up with
a 404.)

http://www.nginx.org/r/location for the details on how nginx chooses
which one location{} block will be used for the current request, if
it's unclear.

All the best,
