I tried to install NextCloud over OpenMediaVault and NextcloudPi via Docker but in both cases I wasn’t able to make it work. Anybody could share a recent working guide for Raspberry Pi?

I tried another time this tutorial but give this error:

Error while trying to create admin user: Failed to connect to the database: An exception occurred in the driver: SQLSTATE[HY000] [2002] Connection refused in the driver: SQLSTATE[HY000] [2002] Connection refused

I really don’t know what can I do.

it sounds your DB doesn’t accept credentials you provided.
Did you adopt user/password values in both services (db and app)?

Hi wwe! The problem was related to the volumes I created, now it’s ok. I need to solve another thing… I want to change the NextCloud default folder location in the external hdd from /nextcloud/files/admin/files to /documents. Furthermore I need copy/erase folders and files from Samba.

This is my stack:

version: '2'

services:
  db:
    image: yobasystems/alpine-mariadb:latest
    command: --transaction-isolation=READ-COMMITTED --binlog-format=ROW
    restart: always
    volumes:
      - /srv/dev-disk-by-uuid-2f9dc745-0f9b-413a-b2bf-794d3f087f59/nextcloud/db:/var/lib/mysql
    environment:
      - MYSQL_ROOT_PASSWORD=PASSWORD
      - MYSQL_PASSWORD=PASSWORD
      - MYSQL_DATABASE=nextcloud
      - MYSQL_USER=nextcloud

  app:
    image: nextcloud
    restart: always
    ports:
      - 80:80
    links:
      - db
    volumes:
      - /srv/dev-disk-by-uuid-2f9dc745-0f9b-413a-b2bf-794d3f087f59/nextcloud/files:/var/www/html/data

      - MYSQL_HOST=db

I don’t really get the question…
assume you want to move the data folder, please follow this how-to:

I have no idea what do you mean by

it looks you want to migrate some existing storage to your new Nextcloud… then I recommend you to look around this forum, make you comfortable with backup/restore procedures, upgrades, hardening before you move all you important data to Nextcloud instance you just installed (with lot of pain)…
