Add the two lines. Dont copy everything.

colbond · 16. September 2015

Ok added. I don't see any new logs showing up, but i thought this was interesting. I noticed that in sites-enabled the webgui config was a symlink to sites-available, so I copied the owncloud config to there from the sites-enabled folder and created the symlink. That results is neither site working properly.

tekkb · 16. September 2015

Why don't you give us a package list for OMV related:

dpkg -l | grep openmediavault

Maybe a plugin is causing an issue.

You should be putting server configs in /etc/nginx/sites-availabe. To create the symlinks you do not have to do it manually via ln -s.

To enable a site that is in sites-available folder:
nginx_ensite nameofsite
service nginx restart

To disable a site that has symlink in /etc/nginx/sites-enabled:
nginx_dissite nameofsite
service nginx restart

A little easier than creating symlinks as you do not need to enter path.

@Rocologo nice job helping him.

colbond · 16. September 2015

Ah thanks for the tip on nginx_ensite. That didn't look right having one symlink and nothing for owncloud in sites-enabled.

Code

tekkb · 16. September 2015

Everything looks OK with your plugins. I have used Mumble in OMV 2.x too so I know that does not cause any problems.

I think the owncloud plugin puts it's config file in the sites enabled instead of creating a symlink from sites available. At least it used to.

Give listing of these:
ls -la /etc/nginx/sites-availabe
ls -la /etc/nginx/sites-enabled
ls -la /etc/nginx/openmediavault-webgui.d

Did you make the openemediavault-webgui.save file??? Move that to another location. I make a scratch folder in the root of my system drive to save things like this. I am not sure if this file is causing a problem but for now get it out of there.

Then:
service php5-fpm restart
service nginx restart

PS- I take that back. It was in sites-available.

colbond · 16. September 2015

99% sure I didn't, since I generally rename file backups with .bak not .save.

Moved that config, restarted services. I also stopped an owncloud client that was running so I can more clearly see what's happening in the logs.

Nothing in any of the error logs. This is what I see in the webgui_access.log when loading the webui:

Code

tekkb · 16. September 2015

I tested by making a .save file in the location. It does not effect anything.

Lets take a look at your web gui config... Give results.

cat /etc/nginx/sites-availabe/openmediavault-webgui

colbond · 16. September 2015

I think I mentioned it farther up but I still think it's relevant. I created a phpinfo page in the owncloud directory and copied it to the openmediavault directory. The one in owncloud loads normally. The one in openmediavault shows the same blank page that the index.php file does. If I 'su - www-data' and 'php index.php':

Code

$ php index.php
PHP Warning:  DOMDocument::load(/etc/openmediavault/config.xml): failed to open stream: Permission denied in /usr/share/php/openmediavault/config.inc on line 113
Failed to load configuration (Warning 1549: failed to load external entity "/etc/openmediavault/config.xml" (line=0, column=0))
Error #3008:<br/>exception 'OMVException' with message 'Failed to load configuration (Warning 1549: failed to load external entity "/etc/openmediavault/config.xml" (line=0, column=0))' in /usr/share/php/openmediavault/config.inc:577<br/>Stack trace:<br/>#0 /usr/share/php/openmediavault/env.inc(22): require_once()<br/>#1 /var/www/openmediavault/index.php(23): require_once('/usr/share/php/...')<br/>#2 {main}

I honestly don't know if that error is relevant (since many files are owned by openmediavault) but it's the first error I've seen that might be related.

tekkb · 16. September 2015

Do you get errors with this:

omv-engined -f -d

Did you try taking the phpinfo page out of the /var/www/openmediavault folder???

colbond · 16. September 2015

Yeah killed the phpinfo page, though it has never seemed to make any difference.

No errors running omv-engined -f -d that I could see.

tekkb · 16. September 2015

I am out of ideas for now... and have to get back to work. If you find anything post it.

Rocologo · 16. September 2015

I recommend that you always keep a phpinfo.php test file in the webroot. This way I can check if Nginx and Php run. If the you can see the PHP information you know the error is in the application and not Nginx+PHP.

If don't get any errors, my guess is that you are looking in the wrong log-file.

colbond · 16. September 2015

webroot isn't publicly available at the moment so I can try that later. Cleared the logs and restarted services, then force refreshed the webui page:

Code

root@openmediavault nginx # tail *error.log
==> error.log <==


==> openmediavault-owncloud_error.log <==


==> openmediavault-webgui_error.log <==
 root@openmediavault nginx # tail *access.log
==> access.log <==


==> openmediavault-owncloud_access.log <==

Okay no errors. What about the php5-fpm.log file ?

If the nginx logs and php5-fpm does not show any errors, you need to test if you can read phpinfo.php through your webbrowser.

colbond · 16. September 2015

I'm not local at the moment so I have to do it via links.

phpinfo in owncloud: works fine
phpinfo in openmediavault: empty page
