Configure Nextcloud snap
The only thing we recommend you do up front is enable HTTPS. Nextcloud snap includes a service for automated HTTPS encryption using Lets Encrypt, or self-signed certificates. Run nextcloud.enable-https -h for more information.
Enable Lets Encrypt in Nextcloud snap:
sudo nextcloud.enable-https lets-encrypt
Enter email address and domain/subdomain to get your SSL certificate
The interface providing the ability to access removable media is not automatically connected upon install, so if you'd like to use external storage (or otherwise use a device in /media or /mnt for data), you need to give the snap permission to access removable media by connecting that interface:
sudo snap connect nextcloud:removable-media
Removable media can be any device (e.g. external-disk-partition, NFS-network mount, SSHFS-network mount etc.).
The device should be available at system boot and mounted by /etc/fstab.
Tip: Ensure USB-boot is disabled in BIOS or use the
--nofailoption in/etc/fstabfor headless boot, especially when connecting an external USB-device.Tip: Recommend creating a dedicated directory in
/media/MYDIRECTORY/or/mnt/MYDIRECTORY/instead of "automount"/media/$USER/DEVICE/directory and mounting the dedicated directory in/etc/fstab.
Removable media must be mounted to either /media or /mnt as root with root permissions and connected to Snap!
The System application requires a bit more access to the system than the snap uses by default (e.g. the ability to monitor network hardware, etc.). If you'd like to utilize those features, you'll need to connect the interface that allows that kind of access:
sudo snap connect nextcloud:network-observe
By default, PHP will use 128M as the memory limit. If you notice images not getting previews generated, or errors about memory exhaustion in your Nextcloud log, you may need to set this to a higher value.
If you'd like to set the memory limit to a higher value (say, 512M), run:
sudo snap set nextcloud php.memory-limit=512M
To set it to be unlimited (not recommended), use -1:
sudo snap set nextcloud php.memory-limit=-1
Note that Nextcloud snap includes a service that runs cron.php every 15 minutes, which will automatically change the cron admin setting to cron for you. By default the cron interval is 15 minutes.
To adjust it (e.g. 10 minutes) simply run:
sudo snap set nextcloud nextcloud.cron-interval=10m
If you want to disable the cron completely, run:
sudo snap set nextcloud nextcloud.cron-interval=-1
To re enable it again simply set the nextcloud.cron-interval snap variable to a value that isn't -1
See managing cron
By default, the snap does not enable HTTP compression. To enable it, run:
sudo snap set nextcloud http.compression=true
To disable it, run:
sudo snap set nextcloud http.compression=false
By default, Nextcloud snap will accept HTTP requests addressed to localhost from the server itself. But when you're setting things up on a remote or virtual server (like an AWS EC2 instance) you’ll need to tell Nextcloud to expect remote browser requests made to your IP address or domain name. Note how you assign a separate ID number (iterating values 0, 1, 2...) for each domain. See multiple trusted domains for config.php configuration options
Set trusted domains (iterating values 0, 1, 2...):
sudo nextcloud.occ config:system:set trusted_domains 0 --value="cloud.yourdomain.com"
sudo nextcloud.occ config:system:set trusted_domains 1 --value="cloud.yourseconddomain.com"
sudo nextcloud.occ config:system:set trusted_domains 2 --value="cloud.yourotherdomain.com"
When you're running Nextcloud snap behind a proxy the snap needs to know about the proxy. Add reverse proxy to trusted proxies. See Nextcloud reverse proxy documentation.
Set trusted proxies (iterating values 0, 1, 2...):
sudo nextcloud.occ config:system:set trusted_poxies 0 --value="your.reverse.proxy.ip"
sudo nextcloud.occ config:system:set trusted_poxies 1 --value="your.other.proxy.ip"
sudo nextcloud.occ config:system:set trusted_poxies 2 --value="another.reverse.proxy.ip"
