Vultr's One-Click oneCloud application is an open-source cloud-based file hosting server that allows you access your files anywhere. It's ready to launch in about a minute. Select a server location, choose your size, and click Deploy Now. One-Click ownCloud runs on Ubuntu Server LTS.

The examples and are used throughout this installation guide. Substitute your server's domain name or IP address.

Install SSL Certificate

This is optional, but recommended. If you skip this step and access the server by IP address, you will see a certificate warning. This warning is normal; the server is configured with a self-signed certificate. You can safely proceed past the warning. See our instructions to bypass the HTTPS warning for self-signed SSL/TLS certificates. Most ownCloud administrators will use a domain name and valid SSL certificate for their site. If you plan to use a commercial SSL certificate, see the Commercial SSL section.
To install a free Let's Encrypt SSL certificate:

  1. Register the name and create a DNS record for the server's IP address. Consult your DNS provider for instructions, or see our guide if using Vultr's DNS.

  2. Verify the DNS has finished propagation, and the name is visible throughout the internet before proceeding. Propagation usually happens quickly, but could take up to 48 hours in some cases.

  3. Connect to your server, with the root login from the Server Information screen.

  4. Request the certificate with certbot. Replace the domain name and email with your values.

     # certbot certonly --nginx --redirect --agree-tos --no-eff-email -d -m 

    Certbot should report success when finished.

  5. Back up the self-signed certificates.

     # mv /etc/nginx/ssl/server.crt ~
     # mv /etc/nginx/ssl/server.key ~
  6. Link the Certbot certificates to Nginx.

     # ln -sfv /etc/letsencrypt/live/ /etc/nginx/ssl/server.crt
     # ln -sfv /etc/letsencrypt/live/ /etc/nginx/ssl/server.key
  7. Restart the webserver.

     # systemctl restart nginx
  8. Edit the trusted_domains setting in config.php.

     # nano /var/www/owncloud/config/config.php
  9. Change the IP address to your domain name. Save and exit the file.

     'trusted_domains' =>
     array (
         0 => '',
  10. Navigate to your instance and verify the certificate is valid. Log in with your User login.

Commercial SSL

You can use a Commercial SSL Certificate instead of the free Let's Encrypt certificate.

How to install a commercial SSL certificate

  1. Obtain a certificate from a certificate authority for your domain.

  2. Replace the server.crt and server.key files in /etc/nginx/ssl/ with the commercial certificate. Refer to your certificate vendor's documentation for details.

  3. Restart the webserver.

     # systemctl restart nginx
  4. Edit the trusted_domains setting in config.php.

     # nano /var/www/owncloud/config/config.php
  5. Change the IP address to your domain name. Save and exit the file.

     'trusted_domains' =>
     array (
         0 => '',
  6. Navigate to your instance and verify the certificate is valid. Log in with your User login.

More Information

Backup Script

The Vultr team has provided a backup script in the /root folder. You can run this file by logging in as root:

# bash

A backup of the ownCloud configuration, database, and uploaded files will be created in the /root folder. Ensure that you have enough space on your VPS to duplicate all of your files before running it.


A MySQL database is running on your VPS. If you need to access the database directly:

  1. Connect to the server via ssh as root.

  2. Log into MySQL.

     # mysql -u root

    The MySQL root password is saved in /root/.my.cnf.

Cockpit Control Panel

Access your Cockpit a control panel at You'll find the username and password on your Server Information page.

Vultr Helper Scripts

Vultr provides helper scripts for common issues. SSH to the server as root to run these scripts.

Reset Nginx

If Nginx fails to load, you may have a typo or corruption in your configuration files. The script will reset the Nginx configuration to default.

# /opt/vultr/
All vhosts have been restored to their default state!

Check Software Versions

For debugging purposes, our support team may ask for your software versions. Run the script.

# /opt/vultr/
    OS: '18.04.4 LTS (Bionic Beaver)'
    OwnCloud: '10.4.1'

Older CentOS instances: Upgrading from 7.0 to 8.0

If your Vultr ownCloud app is running ownCloud 7, it is not recommended to upgrade to 8.0 with the update center, as there are known issues with the ownCloud updater. If you have already started the 8.0 update process, here are some commands that will help resolve upgrade issues.

# (login as root)

# First run this
yum -y install redis
service php-fpm restart

# After upgrade completes - if you see a blank page.
cd /var/www/owncloud
mv apps/calendar/ apps/calendar7
mv apps/contacts/ apps/contacts7

# Review the admin page for any other errors
# https://[SERVER_IP]/index.php/settings/admin

About One-Click Apps

One-Click apps are updated regularly without notice. When launching a One-Click app, you'll receive our latest version. We do not update deployed instances, and you are responsible for keeping the instance up-to-date. If you design an infrastructure based on One-Click apps and need to ensure the same app version in the future, take a snapshot of the initial deployment and create new instances from the snapshot.
