  • [ ] VM-102 created with Ubuntu 24.04 LTS
  • [ ] Nextcloud snap selected during Ubuntu installation (or install manually below)
  • [ ] IP address: 192.168.192.102
  • [ ] Nginx Proxy VM (192.168.192.20) installed
  • [ ] Domain: cloud.yourdomain.com

Estimated Time

30-45 minutes

Snap Already Installed

If you selected Nextcloud during Ubuntu installation, the snap is already installed. Skip Steps 2-4 if already done.

Step-by-Step Instructions

Step 1: SSH to Nextcloud VM

ssh admin@192.168.192.102

Step 2: Update System

sudo apt update && sudo apt upgrade -y

Step 3: Install Snap (if needed)

sudo apt install -y snapd

Verify:

snap version

Step 4: Install Nextcloud

sudo snap install nextcloud

This will take 10-15 minutes. Monitor progress:

sudo snap changes

Wait until status shows "Done".

Step 5: Create Admin Account

sudo nextcloud.manual-install admin <strong-password>

Replace <strong-password> with a secure password.

Step 6: Configure for Reverse Proxy

Configure trusted domains and trusted proxies:

# Add your domain
sudo nextcloud.occ config:system:set trusted_domains 1 --value=cloud.yourdomain.com

# Add nginx-proxy IP as trusted proxy
sudo nextcloud.occ config:system:set trusted_proxies 0 --value=192.168.192.20

# Set URL overwrite
sudo nextcloud.occ config:system:set overwrite.cli.url --value=https://cloud.yourdomain.com/

# Set protocol overwrite
sudo nextcloud.occ config:system:set overwriteprotocol --value=https

Restart Nextcloud:

sudo snap restart nextcloud

Verify configuration:

sudo nextcloud.occ config:system:get trusted_domains
sudo nextcloud.occ config:system:get trusted_proxies

Step 7: Verify Installation

Check Nextcloud status:

sudo nextcloud.occ status

Step 9: Configure Memory Caching

Enable APCu for better performance:

sudo nextcloud.occ config:system:set memcache.local --value='\OC\Memcache\APCu'

Step 10: Adjust PHP Memory Limit

sudo snap set nextcloud php.memory-limit=512M

Step 11: Test Access

After configuring Nginx reverse proxy:

  1. Open browser: https://cloud.yourdomain.com

  2. Login with:
