In this post I'll guide you through installing & optimising NextCloud on Intel based Terra Maters NAS's running TrueNAS 12, in this example I'm using a F2-221 with 10GB of RAM.

If your TerraMaster NAS isn't already running TrueNAS you can find my guide below that will follow you through upgrading your hardware and installing TrueNAS 12.

Dataset

Create Dataset

Start by creating a new dataset from Storage -> Pools, select the three dots on your pool then click Add Dataset.

Give your dataset a name, mine is called CloudStorage remember to set this to yours in other steps! Check the default settings match the ones below then Submit to save.

Set Permissions

From the three dots on your newly created dataset select Edit Permissions.

Set User & Group to www, tick Apply User, Apply Group & Apply Permissions Recursively. Confirm Access Mode matches the below then click save.

Install NextCloud

Install Plugin

From the left-hand menu select Plugins, NextCloud then INSTALL.

Name your Jail, I've called mine BifrostCloud remember to change this to yours in later steps, change NAT to DHCP to allow your router to set the new Jails IP Address. Use your router to assign the address permanently.

Attach Dataset

Copy NextCloud data directory to your new Dataset

Don't run these commands from your jail

cp -r /mnt/bifrost-pool/iocage/jails/BifrostCloud/root/usr/local/www/nextcloud/data/ /mnt/bifrost-pool/CloudStorage/

Delete NextCloud data folder

rm -r /mnt/bifrost-pool/iocage/jails/BifrostCloud/root/usr/local/www/nextcloud/data

Set Permissions

chown -R www:www /mnt/bifrost-pool/CloudStorage/

From the Jail page stop your NextCloud instance then select MOUNT POINTS

Go to ACTIONS then Add

Now use the source/destination path as seen below except modified to fit your installation.

Configure NextCloud

Add Trusted Domains

Add your assigned IP Address & Domain Name to Trusted Domains.

nano /mnt/bifrost-pool/iocage/jails/BifrostCloud/root/usr/local/www/nextcloud/config/config.php

 'trusted_domains' =>
  array (
    0 => 'localhost',
    1 => '192.168.0.61',
    2 => 'cloud.joelduncan.io',
  ),

Setup SSL

Copy SSL pem & key files to the following directory

/mnt/bifrost-pool/iocage/jails/BifrostCloud/root/etc/ssl/

Add the following to the NextCloud Nginx configuration

nano /mnt/bifrost-pool/iocage/jails/BifrostCloud/root/usr/local/etc/nginx/conf.d/nextcloud.conf

        ssl on;
        ssl_certificate         /etc/nginx/ssl/joelduncan-io-certificate.pem;
        ssl_certificate_key     /etc/nginx/ssl/joelduncan-io-key.pem;
        ssl_session_timeout 5m;
        ssl_ciphers               'AES128+EECDH:AES128+EDH:!aNULL';
        ssl_protocols              TLSv1 TLSv1.1 TLSv1.2;
        ssl_prefer_server_ciphers on;

Restart Nginx from the Jail Shell

sudo service nginx restart
sudo service nginx reload

Optimise PHP-FPM

Run these commands outside your jail

Tweak your PHP-FPM configuration

nano /mnt/bifrost-pool/iocage/jails/BifrostCloud/root/usr/local/etc/php-fpm.d/nextcloud.conf

Add/Modify to match below

pm = dynamic
pm.max_children = 64
pm.start_servers = 16
pm.min_spare_servers = 16
pm.max_spare_servers = 32

Correct aliases

nano /mnt/bifrost-pool/iocage/jails/BifrostCloud/root/usr/local/etc/nginx/conf.d/www.conf

Uncomment the below existing entries.

;env[HOSTNAME] = $HOSTNAME
;env[PATH] = /usr/local/bin:/usr/bin:/bin
;env[TMP] = /tmp
;env[TMPDIR] = /tmp
;env[TEMP] = /tmp

Restart PHP-FPM from inside the jail

sudo service php-fpm restart

Setup Complete

Everything is ready to go but before accessing your instance by its IP or domain you will need the MySQL and NextCloud credentials created by the plugin, you can find them in the POST INSTALL NOTES

Plugins -> NextCloud -> Drop Down -> POST INSTALL NOTES

Update NextCloud

Must be done from the Jail

php74-phar is required and can be installed with the following command

pkg install sudo php74-phar

Then the following to perform a update

sudo -u www php /usr/local/www/nextcloud/updater/updater.phar

Misc

Run OCC Commands

Must be done from the Jail

From your NextCloud installation directory

su -m www -c 'php ./occ maintenance:mode --off'
