NginX broken. Cannot login via webgui. Please Help

seanbw · 25. April 2016

I have the same problem as SSH ok, shares ok, but no access to web GUI ?.
I tried to access the webgui and got a connection refused. Previously I was updating a bunch of plugins including sabnzbd and all worked. I tried to update a setting in sabnzbd and got a

Code

Incorrect parameter. Configuration is locked

I tried to go back but it won't give me the plugin page again.
After that the whole problem started with me trying to login to the main page and getting a connection refused. I came to this site and tried all the suggestions in this link: No WebGUI and update is not possible .
I got this:

Zitat

root@omv:~# ls -la /etc/nginx/sites-enabled/total 12drwxr-xr-x 2 root root 4096 Apr 22 23:29 .drwxr-xr-x 6 root root 4096 Apr 9 11:45 ..lrwxrwxrwx 1 root root 47 Apr 22 23:29 openmediavault-nginx -> /etc/nginx/sites-available/openmediavault-nginx-rw-r--r-- 1 root root 2382 Apr 22 23:29 openmediavault-owncloudlrwxrwxrwx 1 root root 40 Apr 9 10:35 openmediavault-webgui -> ../sites-available/openmediavault-webguiroot@omv:~#

I then came to this thread and tried all the suggestions in the linked forum.Nothing worked until I tried this:

Zitat

root@omv:~# service nginx startStarting nginx: nginx: [emerg] invalid number of arguments in "proxy_set_header" directive in /etc/nginx/openmediavault-webgui.d/sub.conf:5nginx: configuration file /etc/nginx/nginx.conf test failed

This told me nginX is somehow broken.
I then tried the omv-mkconf nginx and got nothing.
After that I tried: root@omv:~# service nginx start and got this:

Zitat

Starting nginx: nginx: [emerg] invalid number of arguments in "proxy_set_header" directive in /etc/nginx/openmediavault-webgui.d/sub.conf:5nginx: configuration file /etc/nginx/nginx.conf test failed

So I tried the omv-firstaid repair of the webgui. After closing the firstaid repair, I got this:

Zitat

root@omv:~# omv-firstaidUpdating web administration settings. Please wait ...{"response":null,"error":{"code":4000,"message":"Failed to execute command 'export LANG=C; nginx -t 2>&1': nginx: [emerg] invalid number of arguments in \"proxy_set_header\" directive in \/etc\/nginx\/openmediavault-webgui.d\/sub.conf:5\nnginx: configuration file \/etc\/nginx\/nginx.conf test failed","trace":"exception 'OMVException' with message 'Failed to execute command 'export LANG=C; nginx -t 2>&1': nginx: [emerg] invalid number of arguments in \"proxy_set_header\" directive in \/etc\/nginx\/openmediavault-webgui.d\/sub.conf:5\nnginx: configuration file \/etc\/nginx\/nginx.conf test failed' in \/usr\/share\/openmediavault\/engined\/module\/webserver.inc:41\nStack trace:\n#0 \/usr\/share\/openmediavault\/engined\/rpc\/config.inc(180): OMVModuleNginxAbstract->applyConfig()\n#1 [internal function]: OMVRpcServiceConfig->applyChanges(Array, Array)\n#2 \/usr\/share\/php\/openmediavault\/rpcservice.inc(125): call_user_func_array(Array, Array)\n#3 \/usr\/share\/php\/openmediavault\/rpc.inc(79): OMVRpcServiceAbstract->callMethod('applyChanges', Array, Array)\n#4 \/usr\/sbin\/omv-engined(500): OMVRpc::exec('Config', 'applyChanges', Array, Array, 1)\n#5 {main}"}}Failed to execute RPC (service=Config, method=applyChanges)

I am sorry but after this, I don't know what to try.
I have tried all the PC in the house. None works.
I have tried incognito. It does not work.
I have flushed my cache. It still does not work.
I have somehow broken nginX but don't know how and don't know how to repair.
I am on OMV 2.2 I think on HPZ800 but the server is a Gen 8 1610T running omv only.
Please help.

The problem is that a plugin writes an incorrect nginx configuration file.

Uninstall the plugin (i assume sabnzbd) via CLI
Run omv-mkconf nginx and restart the service

and everything will work again.

seanbw · 25. April 2016

I am not sure it was sabnzbd alone but I will run the following:
apt-get remove --purge sabnzbdplus
apt-get clean
omv-mkconf nginx
service nginx restart
omv-update

I got the following response to sabnzbd:
E: Unable to locate package sabnzbd
and to sabnzbdplus:
Package 'sabnzbdplus' is not installed, so not removed

Reason I say its not sabnzbd alone is that plex gives this:

Also although I see the shares in my Windows explorer, the moment I click on them, they disappear, both plex and minidlna.

seanbw · 25. April 2016

After following:Everything down. Can't Login.
I ran

Code

omv-mkconf omvextrasorg aptclean

and got this result which seemed to have made the error message smaller:

Code

root@omv:~# omv-mkconf nginx
root@omv:~# service nginx restart
Restarting nginx: nginx: [emerg] invalid number of arguments in "proxy_set_header" directive in /etc/nginx/openmediavault-webgui.d/sub.conf:5
nginx: configuration file /etc/nginx/nginx.conf test failed
root@omv:~#

Can I delete the configuration file and will nginX rebuild automatically?

Anybody!!!!

No OMV doesn't rebuild that file. Your /etc/nginx/nginx.conf should look like this:

Code

worker_processes 4;
pid /var/run/nginx.pid;


events {
        worker_connections 768;
        # multi_accept on;

        tcp_nodelay on;
        keepalive_timeout 65;
        types_hash_max_size 2048;
        # server_tokens off;


        # server_names_hash_bucket_size 64;
        # server_name_in_redirect off;


        include /etc/nginx/mime.types;
        default_type application/octet-stream;


        ##
        # Logging Settings
        ##


        access_log /var/log/nginx/access.log;
        error_log /var/log/nginx/error.log;


        ##
        # Gzip Settings
        ##


        gzip on;
        gzip_disable "msie6";


        # gzip_vary on;
        # gzip_proxied any;

        ##


        #include /etc/nginx/naxsi_core.rules;


        ##

        include /etc/nginx/sites-enabled/*;

Thank you.
I bit the bullet and reinstalled hopefully for the last time.
So far so good.
I only wish I had copied the config.xml. Now my transmission is not working but I will sort it out.
Thank you.
