Nextcloud on Raspberry Pi3 with nginx

Smaig · September 29, 2016, 1:13pm

i didn’t forget, i’ve just rechanged it not to put my domain online

another ways to my problem might be this error in nginx/error.log, what do you think? :

worker process 766 exited on signal 7

All my access generate a new line as above…

riegerCLOUD · September 29, 2016, 1:28pm

puh, please paste the nginx.conf here
please run the default.conf to ckeck whether nginx still works or not in general

Smaig · September 29, 2016, 1:46pm

root@host:/var/log# ulimit -n
65536

nginx.conf :

user www-data;
worker_processes 4;

error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;

worker_rlimit_nofile 65536;

events {
worker_connections 65536;
multi_accept on;
use epoll;
}

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

log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                  '$status $body_bytes_sent "$http_referer" '
                  '"$http_user_agent" "$http_x_forwarded_for"';

access_log  /var/log/nginx/access.log  main;

sendfile        on;
tcp_nopush     on;
tcp_nodelay         on;
keepalive_timeout  65;
types_hash_max_size 2048;
server_tokens off;

include /etc/nginx/conf.d/*.conf;

}

run default and it’s working like a charm.

Also tried to modify

include /etc/nginx/conf.d/*.conf;

to

include /etc/nginx/conf.d/gateway.conf;

or

include /etc/nginx/conf.d/gateway.conf;
include /etc/nginx/conf.d/nextcloud.conf;

Found that is nextcloud.conf which provok worker process exit in error.log

please try to reduce the amount of WORKER_CONNECTION to 1024 and restart nginx.

Smaig · September 29, 2016, 10:21pm

I’ve just tried 1024 and 768 with no result… (on my other pi 3 with a different installation, i use 768)

also try to change worker_processes to auto, to disable multi-accept and use epoll…still the same message in error.log

I’ve put back the configuration without gateway.conf and everything is working again using those two files:

http://www.megafileupload.com/g1v8/nextcloud.conf.https
http://www.megafileupload.com/g1v9/nginx.conf

Hi Carsten,

I’ve put log in debug and here is what i’ve got with the working nextcloud.conf.https file:

Of course, i’ve changed my client ip and domain in this logs

riegerCLOUD · October 2, 2016, 12:00pm

i am sorry, but i do not know what to change.
As i said before, your config is doing well on my pi3.

Many ohters did use my guide and succeded, so please make a doublecheck of all the steps i mentioned in my guide.

I suggest to ask e.g. the nginx-community or maybe anybody else in this forum may assist you?!
appologize, carsten

Smaig · October 2, 2016, 8:14pm

No worries Carsten. I think it might come from my nginx compilation that could be a little bit different on Raspbian than ubuntu. I’ll ask on nginx forum or try to use ubuntu

Hier habe ich ein Tutorium erstellt wie man Nextcloud 11 auf dem Raspberry Pi 3 installiert. Ich benutze dabei die Installation-Anleitung unter dem Ubuntu und gebe Hinweise bezüglich PHP 7

ojp · January 11, 2017, 1:50pm

Hi Carsten,
First of all, thank you for your guide, it is the best one available - I think I know it top to bottom by know
Im looking towards 64 bit distro’s (eg Leap) and wonder if on the Pi3 (Ngnix, Php7 etc) de performance would be much better. Could you comment that?
And if so, perhaps adapting your brilliant guide?
Sll the best,
Olaf

riegerCLOUD · January 11, 2017, 2:39pm

thank you very much!
if i got you right, there won’t be a significant performance increase just in case you switch your os from 32 to 64 bit.
but filehandling and memoryhandling gain more options.
e.g. files larger than 2GB
