Simple DLNA Renderer for Odroid C1+...or not?

Okay, lighttpd intallation successful, no errors.
edit: still errors: warning: directory permissions differ on /var/cache/lighttpd/
filesystem: 755 package: 700

Code:

sudo mv /etc/lighttpd/lighttpd.conf /etc/lighttpd/lighttpd.conf-original

done

Code:

sudo nano /etc/lighttpd/lighttpd.conf

done

Code:

server.document-root = "/mnt/dsmusic"

mimetype.assign = (
  ".jpg" => "image/jpeg",
  ".png" => "image/png",
 )

done, but...doesn't it has to be "/mnt/MPD" because of Rune's specification in mpd.conf? After switching to RuneAudio there's no mount point "dsmusic" (it was with DietPi).

Code:

sudo systemctl enable lighttpd

done

...reboot.

[*drum-roll*]...no covers.

Next I did...(instructed by myself, if I'm right)

Result(s):

Code:

sudo systemctl [COLOR="Blue"]status/stop/enabled/start[/COLOR] lighttpd

successively

Result(s):

PS:I didn't want to sit around and just tried something out ...even it was "pointless". But an error message is a message, too.

PPS: If we've messed up too much now, I'll be happy to do it all over again.

Gimme a good feeling...RuneAudio fresh from the start.

Dear Linuxfan,

I'm currently busy with spontaneous holiday preparations (going to Venice) and I don't know how much time is left for the project at the moment.

I say thank you very much and if you're willing to help me afterwards it would be fine. Until then, an "out-of-the-box-RuneAudio" is okay for me and I have enough time to think about if it's worth to go on.

phofman · 2020-09-22 7:17 pm

You really have to make sure nginx and lighttpd do not run concurrently - the second one to be started will fail as the port 80 is already taken by the first process.

lighttpd failed to start because of a permissions issue, possibly because RuneAudio runs as root?
I suggest you stick with version 1.4.37 of lighttpd. After installation, change permissions on /var/log/lighttpd

Code:

chmod 755 /var/log/lighttpd

Before going any further, it's worth starting lighttpd to check that it's working -

Code:

systemctl start lighttpd

If you see "code=exited" or "inactive (dead)" then change the permissions further -

Code:

chmod 777 /var/log/lighttpd

then

Code:

systemctl restart lighttpd

If it still doesn't start, the final thing to try is to add this line to /etc/lighttpd/lighttpd.conf
server.username = "root"
so the entire contents would be -

Code:

server.document-root = "/mnt/MPD"

server.username = "root"

mimetype.assign = (
  ".jpg" => "image/jpeg",
  ".png" => "image/png",
 )

Once you see that lighttpd starts successfully, you're ready to enable it at start up -

Code:

sudo systemctl enable lighttpd

And reboot, confident that lighttpd will start!

masterkw · 2020-09-23 1:07 pm

I still have a little time...more taking it.

To approach the whole thing more relaxed I've flashed a second mSDHC with RuneAudio for testing purposes.

I don't repeat all the things had to be done, here are only the essential deviations...and the results.

- lighttpd-1.4.37-1-armv7h installation successful but still inactive.
- nginx still active after reboot although disabled

chmod 755 /var/log/lighttpd

There isn't such a directory, only /usr/bin/lighttpd and /usr/lib/lighttpd. I've chosen .../bin/... instead and set

Code:

 chmod 777 /usr/bin/lighttpd

*reboot*

Identical constellation.

)

After a quick look into mpd.conf, user there is called "mpd". Did an accordingly customization & reboot...

lighttpd and mpd are active and nginx is disabled!

Next step...MaximumMPD:

- customized and commenting out coverart_ctl.php
- reboot
- configured MaxMPD, restart app..

...still no covers. :xeye:

There isn't such a directory

There's something wrong there, because lighttpd-1.4.37-1-armv7h.pkg.tar.xz should definitely create that directory.
I suggest for now to concentrate only on lighttpd - there are ways to diagnose if it's serving cover art, without any involvement of MPD.
First I suggest you create the missing directory - because lighttpd will want to write log files there.

Code:

sudo mkdir /var/log/lighttpd

Now restart lighttpd

Code:

sudo systemctl restart lighttpd

Then on any computer connected to your LAN, launch a web browser and go to the IP address of your Odroid C1. You should see a basic listing of your music directories.
You need to get to this point, before MaximumMPD has any chance of seeing the cover art.

masterkw said:

Don't bother with this modification - it only affects how the Rune app serves cover art (via nginx) and you're now using a completely separate web server (lighttpd).

linuxfan · 2020-09-23 2:07 pm

Oh, and now you have created the correct directory for the log file, you can open that log file to check for any problems -

Code:

nano /var/log/lighttpd/error.log

masterkw · 2020-09-23 2:14 pm

BTW, I've found a "coverart usage guide" on MaximumMPD (infos next to bottom). Keyword: config nginx-server. Could this be helpful for the "origin way" how RuneAudio was configured?

I'm still back in a few minutes..

linuxfan · 2020-09-23 2:22 pm

Yes, that could be useful for nginx configuration - but it appears that the Rune app manages much of that configuration within its own separate configuration file(s), then "manages" how nginx is run ...
so that information would best be used by the RuneAudio developers, so they can better set up their configuration files.

If you search the Rune forum you will see that cover art is a big problem for many users - I think the Rune developers should consider dropping nginx and using lighttpd instead.

masterkw · 2020-09-23 2:48 pm

Okay, it seems Rune is a little idiosyncratic.

linuxfan said:
sudo mkdir /var/log/lighttpd

I did it five times...made directory, checked directory's existence, restart lighttpd, reboot...Rune removed it. So there's no error.log-file, too.

A last countertest: changed lighttpd.conf user back to "root"...lighttpd start failed ("mpd" works)

Last but not least, whatever "we" have done, calling Odroid's IP is "404 error"

===
Edit:
===

Took back all the changes and disabled "lighttpd" and enabled "nginx"
...Rune's still online again.

linuxfan · 2020-09-23 3:07 pm

Ah, so Rune OS has a non-persistent /var directory. That's what has been causing so much trouble.
OK, let's set a different location for log files, say /etc/log/lighttpd

Code:

mkdir /etc/log
mkdir /etc/log/lighttpd

Now you must configure lighttpd to use this new location

Code:

sudo nano /etc/lighttpd/lighttpd.conf

insert this line before all the jpeg stuff -

Code:

server.errorlog  = "/etc/log/lighttpd/error.log"

Restart lighttpd

Code:

sudo systemctl restart lighttpd

check that a log has been created

Code:

ls /etc/log/lighttpd

Now try again to browse to your C1's IP address.

Signing off for the night.

masterkw · 2020-09-23 5:06 pm

Done everything.

linuxfan said:

No log has been created.

reboot - lighttpd task start failed, still no log file
removed conf entry server.errorlog = "/etc/log/lighttpd/error.log"
reboot - lighttpd task start
call C1's IP - 404 error
back to nginx/disabled lighttpd - Rune is working

Now...

Code:

sudo shutdown masterkw +2 glass of red wine

linuxfan · 2020-09-23 10:34 pm

I will try these configuration changes to my own installation of lighttpd, later today.

linuxfan · 2020-09-24 8:27 am

I reproduced the problem on my desktop computer running an Ubuntu-based Linux.
As it launches, lighttpd looks for /var/log/lighttpd (where a log file will be written upon exit) but if this directory does not exist, lighttpd will fail to launch.
lighttpd also attempts to write a PID file to /var/run and if this directory does not exist, it will also fail to launch.

The problem is that Arch Linux mounts /var/log (or possibly even /var) as a temporary filesystem, which is volatile, so all changes are lost at shutdown/reboot.

I configured lighttpd to write the log file and PID file to somewhere other than /var ... but this is not an elegant solution.
I think the proper solution is here -
Arch Linux ARM • View topic - Problem with lighttpd logs
it's a method of re-creating temporary files/directories at each boot up.

Here's the complete setup, to avoid confusion with earlier posts:
I'm assuming you are logged into RuneOS as "root"

Download and install lighttpd

Code:

wget [url]http://tardis.tiny-vps.com/aarm/packages/l/lighttpd/lighttpd-1.4.37-1-armv7h.pkg.tar.xz[/url]
pacman -U lighttpd-1.4.37-1-armv7h.pkg.tar.xz

Open the lighttpd configuration file in a text editor

Code:

nano /etc/lighttpd/lighttpd.conf

replace all the contents with this -

Code:

server.document-root = "/mnt/MPD"

mimetype.assign = (
  ".jpg" => "image/jpeg",
  ".png" => "image/png",
 )

Now to fix the /var/log directory, first check that Rune has the directory /etc/tmpfiles.d

Code:

ls /etc/tmpfiles.d

If not, stop. I will give you my "ugly" solution instead.
If the directory exists, create a new configuration file with nano

Code:

nano /etc/tmpfiles.d/lighttpd.conf

insert this single line -

Code:

d /var/log/lighttpd 0755 http http - -

Save.
Reboot.
Check that var/log/lighttpd exists

Code:

ls var/log/lighttpd

If so, go ahead and enable lighttpd

Code:

systemctl enable lighttpd

In a web browser go to the C1's IP address. You should see music directories listed.
If so, MaximumMPD should now show cover art.

phofman · 2020-09-24 9:20 am

tmpfiles.d is a nice solution :up:

linuxfan · 2020-09-24 9:34 am

Amendment: there's one more line to include in /etc/lighttpd/lighttpd.conf

Code:

server.document-root = "/mnt/MPD"
[COLOR="Red"]dir-listing.activate = "enable"[/COLOR]

mimetype.assign = (
  ".jpg" => "image/jpeg",
  ".png" => "image/png",
 )

Otherwise when you browse to your C1's IP address you may see 403 - Forbidden
and for the sake of diagnosis we really want to be able to see your directories listed.

masterkw · 2020-09-24 10:29 am

Okay, all steps done with a fresh Rune install!

...but still no covers in MaxMPD

linuxfan · 2020-09-24 10:53 am

It appears that lighttpd is now working. That's great.
Any MPD client which conforms to MPD specifications should be able to display cover art at this point.

I think all you need to do is change MaximumMPD's HTTP Port value from 8080 to 80

And let me ask a stupid question - your configuration files for both MPD (/etc/mpd.conf) and lighttpd (/etc/lighttpd/lighttpd.conf)
have the same value, right? /mnt/MPD

masterkw · 2020-09-24 11:10 am

Config files are identical.

If I change port to 80, MaxMPD starts processing the queue.

a number of several thousand entries are displayed, about four times the actual quantity
each directory is repeated several times when read in
with an attached error "album art not found".

If I restart the app all config entries were cleared and status displayed "done".
