How to use Nextcloud with Vultr Block Storage and Object Storage

Introduction

Nextcloud is a self-hosted open-source file hosting application that lets you store, edit and share files privately using your own server. This article explains how to use Nextcloud with Vultr's Block Storage and Object Storage to maximize the application's storage potential.

Prerequisites

1. Setup the Server

  1. Create a new server user account.

     # adduser example-user

  2. Grant the new user sudo privileges.

     # adduser example-user sudo

  3. Switch to the new user.

     # su example-user

  4. Request a Free Let's Encrypt SSL certificate using Certbot. Replace cloud.example.com with your linked domain.

     $ sudo certbot --nginx -d cloud.example.com --agree-tos

  5. To access Nextcloud using the domain, edit the config.php file.

     $ sudo nano /var/www/html/config/config.php

  6. Find the trusted_domain array.

     'trusted_domains' =>
   array (
   0 => '<your-server-ip-address',
 ),

  7. Add your domain as a new entry.

     'trusted_domains' =>
 array (
 0 => '<your-server-ip-address>',
 1 => 'cloud.example.com',
 ),

    Save and exit the file.

  8. Restart Nginx to load changes.

     $ sudo systemctl restart nginx

Setup Nextcloud with Vultr Block Storage

2. Setup the Block Storage Volume

  1. List all storage devices attached to your server.

     $ lsblk

    Output:

     NAME   MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
 loop1    7:1    0 70.3M  1 loop /snap/lxd/21029
 loop2    7:2    0 55.4M  1 loop /snap/core18/2128
 loop3    7:3    0 44.7M  1 loop /snap/snapd/15904
 loop4    7:4    0 55.5M  1 loop /snap/core18/2409
 loop5    7:5    0 61.9M  1 loop /snap/core20/1494
 loop6    7:6    0 67.8M  1 loop /snap/lxd/22753
 sr0     11:0    1 1024M  0 rom
 vda    252:0    0   25G  0 disk
 └─vda1 252:1    0   25G  0 part /
 vdb    252:16   0   40G  0 disk

    Your first block storage device displays as vdb. Any additional attachments display as vdc, vdd, and so on.

  2. Set the volume disk label to gpt.

     $ sudo parted -s /dev/vdb mklabel gpt

  3. Create a new primary partition occupying the full disk space.

     $ sudo parted -s /dev/vdb unit mib mkpart primary 0% 100%

  4. Verify the new partition.

     $ lsblk

    Output:

     NAME   MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
 loop1    7:1    0 70.3M  1 loop /snap/lxd/21029
 loop2    7:2    0 55.4M  1 loop /snap/core18/2128
 loop3    7:3    0 44.7M  1 loop /snap/snapd/15904
 loop4    7:4    0 55.5M  1 loop /snap/core18/2409
 loop5    7:5    0 61.9M  1 loop /snap/core20/1494
 loop6    7:6    0 67.8M  1 loop /snap/lxd/22753
 sr0     11:0    1 1024M  0 rom
 vda    252:0    0   25G  0 disk
 └─vda1 252:1    0   25G  0 part /
 vdb    252:48   0   40G  0 disk
 └─vdb1 252:49   0   40G  0 part

    A new vdb1 volume with the type part should display below the main vdb disk.

  5. Create a new directory in /mnt to use as a mount point for volume.

     $ sudo mkdir /mnt/nextcloud-data

  6. Mount the block storage volume.

     $ sudo mount -o defaults /dev/vdb1 /mnt/nextcloud-data/

  7. Verify the new volume mount point.

     $ lsblk

    Output:

     NAME   MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
 loop1    7:1    0 70.3M  1 loop /snap/lxd/21029
 loop2    7:2    0 55.4M  1 loop /snap/core18/2128
 loop3    7:3    0 44.7M  1 loop /snap/snapd/15904
 loop4    7:4    0 55.5M  1 loop /snap/core18/2409
 loop5    7:5    0 61.9M  1 loop /snap/core20/1494
 loop6    7:6    0 67.8M  1 loop /snap/lxd/22753
 sr0     11:0    1 1024M  0 rom
 vda    252:0    0   25G  0 disk
  └─vda1 252:1    0   25G  0 part /
 vdb    252:48   0   40G  0 disk
  └─vdb1 252:49   0   40G  0 part /mnt/nextdata

  8. Enable persistent mounting to automatically mount the block storage volume at boot time.

     $ sudo echo /dev/vdb1 /mnt/nextcloud-data ext4 defaults,noatime,nofail 0 0 >> /etc/fstab

  9. Create a sample text file in the mount directory to confirm read and write access.

     $ sudo echo "hello world, your nextcloud intergration works"> /mnt/nextcloud-data/sample.txt

3. Configure Nextcloud to use Block Storage

  1. Using a web browser of your choice, visit your domain.
