NextCloud Installation

[How-To] Install Nextcloud on Debian 12

Prerequisites

To complete this guide, ensure you have the following:

Installing Apache2 Web Server

In the first step, you will be installing the Apache2 web server that will be used to run Nextcloud.

First, update your Debian package index via the apt update command below. When finished, you will get the latest package information that allows you to install the latest version of packages.


sudo apt update

Now enter the following apt install command to install the Apache web server. Input y to confirm when prompted, then press ENTER to proceed to the installation.

sudo apt install apache2 -y

After Apache2 is installed, execute the systemctl commands below to verify the apche2 service status.

sudo systemctl is-enabled apache2
sudo systemctl status apache2

The output enabled should indicate the apache2 service will start automatically upon the system startup. And the status active (running) confirms that the apache2 service is running.

Installing UFW

After Apache2 is installed, you will install the UFW (Uncomplicated Firewall) and open ports for OpenSSH, HTTP, and HTTPS. You will set up UFW as the default firewall on your Debian server.

Install the ufw package to your Debian server via the apt install command below. Input y to confirm the installation and press ENTER to proceed.

sudo apt install ufw -y

After ufw is installed, execute the ufw commands below to allow the ssh service and enable ufw.

sudo ufw allow OpenSSH
sudo ufw enable

Input y when asked to start and enable the ufw service. If successful, you should get an output "Firewall is active and enabled on system startup".

With the ufw running, you should add both HTTP and HTTPS ports that the Apache2 webserver will use.

Run the ufw command below to get the list of application profiles available on ufw. You should see profiles such as OpenSSH for ssh service and WWW Full for Apache2 webserver, both HTTP and HTTPS protocols.

sudo ufw app list

Now run the following command to add and enable the WWW Full profile and reload ufw to apply the changes.

sudo ufw allow "WWW Full"
sudo ufw reload

Lastly, run the ufw status command below to verify enabled rules in ufw. Ensure you got the WWW Full profile enabled, which means both HTTP and HTTPS ports are opened.

sudo ufw status

Installing PHP 8.2

The latest Debian 12 Bookwork comes with PHP 8.2 packages by default, which is the PHP version that is recommended for installing Nextcloud. Now, you will install PHP 8.2 packages and configure PHP for the Nextcloud installation. You will also enable the PHP Opcache that will be used as the memory caching for Nextcloud.

Run the apt install command below to install PHP packages to your Debian system. The command will install PHP and some extensions needed by Nextcloud, such as GD, MySQL, Imagick, pear, and apcu. Check the Nextcloud server requirements page to get the full list of packages that you need.

sudo apt install -y php php-curl php-cli php-mysql php-gd php-common php-xml php-json php-intl php-pear php-imagick php-dev php-common php-mbstring php-zip php-soap php-bz2 php-bcmath php-gmp php-apcu libmagickcore-dev php-redis php-memcached

Input y to confirm the installation, then press ENTER to proceed.

After PHP is installed, check the PHP version and enabled PHP extensions using the below command.

php --version
php -m

You should see PHP 8.2 is installed with extensions enabled, such as GD, MySQL, Imagick, xml, and zip.

Next, run the nano editor command below to open the PHP configuration file /etc/php/8.2/apache2/php.ini.

sudo nano /etc/php/8.2/apache2/php.ini

Uncomment the date.timezone parameter and input the proper timezone for PHP. EST = America/New_York

date.timezone = Europe/Amsterdam

Increase the default value of parameters memory_limit, upload_max_filesize, post_max_size, and max_execution_time. Change the value as you need.

memory_limit = 512M
upload_max_filesize = 500M
post_max_size = 600M 
max_execution_time = 300

Enable file_uploads and allow_url_fopen by changing the default value to On.

file_uploads = On
allow_url_fopen = On

Disable the parameter display_errors and output_buffering by changing the default value to Off.

display_errors = Off
output_buffering = Off

Uncomment the zend_extension parameter and change the value to opcache. This will enable PHP OPcache, which is needed for Nextcloud.

zend_extension=opcache

Add the following lines to the [opcache] section. The OPCache configuration is recommended by Nextcloud.

opcache.enable = 1
opcache.interned_strings_buffer = 12
opcache.max_accelerated_files = 10000
opcache.memory_consumption = 128
opcache.save_comments = 1
opcache.revalidate_freq = 1

Save the file and close the editor when finished.

Lastly, enter the systemctl command below to restart the apache2 service. Every time you make changes to the PHP configuration, restart the apache2 service to apply the changes that you've made.

sudo systemctl restart apache2

Installing MariaDB Server

After installing the Apache2 web server and PHP 8.2, you will install the MariaDB server that will be used as the database for Nextcloud and configure the MariaDB root password via the mariadb-secure-installation utility.

Install the MariaDB server via the apt install command below. Input y when prompted and press ENTER to proceed with the installation.

sudo apt install mariadb-server -y

Once MariaDB is installed, enter the following systemctl commands to verify the mariadb service.

sudo systemctl is-enabled mariadb
sudo systemctl status mariadb

The output enabled indicates that the mariadb service will be run automatically at system boot. And the output active (running) should indicate that the mariadb service is running.

Now that the MariaDB server is running, you should secure the MariaDB installation, and this can be done via the mariadb-secure-installation utility. The mariadb-secure-installation command helps you set up the MariaDB root password and authentication and helps you remove the default anonymous user default database test.

Execute the mariadb-secure-installation command to secure your MariaDB server.

sudo mariadb-secure-installation

During the process, you should input Y to agree and apply the configuration to MariaDB, or input n to disagree and leave the configuration as default. Below are some MariaDB configurations that you will be asked for:

With this, the MariaDB server is installed and secured.

Creating Database and User

After installing the MariaDB server, now you will create a new database and user for Nextcloud. To achieve that, you must log in to the MariaDB server via the mariadb client.

Log in to the MariaDB server using the mariadb client command below. Input the MariaDB root password when prompted.

sudo mariadb -u root -p

Once logged in to MariaDB, run the following queries to create a new Mariadb database and user for Nextcloud. In this example, you will create a new database nextcloud_db, and the user nextclouduser with the password StrongPassword. Be sure to change the password StrongPassword with a new password.

CREATE DATABASE nextcloud_db;
CREATE USER 'nextclouduser'@'%' IDENTIFIED BY 'StrongPassword';
GRANT ALL PRIVILEGES ON nextcloud_db.* TO 'nextclouduser'@'%';
FLUSH PRIVILEGES;

Lastly, run the following query to ensure that the user nextclouduser can access the database nextcloud_db.

SHOW GRANTS FOR nextclouduser@localhost;

If everything goes well, you should see the user nextclouduser has privileges to the database nextcloud_db.

Type quit to exit from the MariaDB server and complete this section.

Downloading Nextcloud Source Code

At this point, all software packages for running Nextcloud are installed. Now you will download the latest version of Nextcloud source code, then install it. Check the Nextcloud download page before you start to get information about Nextcloud's latest version.

Before downloading the Nextcloud source code, run the apt install command below to install curl and unzip.

sudo apt install curl unzip -y

Move to the /var/www directory and download the Nextcloud source code via the curl command below. Visit the Nextcloud Download page to get the latest version of Nextcloud.

cd /var/www/
sudo curl -o nextcloud.zip https://download.nextcloud.com/server/releases/latest.zip

Now extract the nextcloud.zip file via unzip command, then change the ownership of the nextcloud directory to www-data.

sudo unzip nextcloud.zip
sudo chown -R www-data:www-data nextcloud

With this, you should notice the Document Root directory for Nextcloud installation is /var/www/nextcloud directory. And the Apache2 web server can access the nextcloud source code via user www-data.

Configuring Apache2 Virtual Host

After downloading the Nextcloud source code, you must create the new Apache2 virtual host configuration that will be used to run Nextcloud. Be sure you have the domain name pointed to your Debian server IP address for your Nextcloud installation.

Create a new Apache2 virtual host configuration /etc/apache2/sites-available/nextcloud.conf using the nano command below.

sudo nano /etc/apache2/sites-available/nextcloud.conf

Change the domain name within the ServerName parameter with your domain, and the full path of log for both ErrorLog and CustomLog parameters.

<VirtualHost *:80>
    ServerName cloud.leffringo.com
    DocumentRoot /var/www/nextcloud/

    # log files
    ErrorLog /var/log/apache2/cloud.leffringo.com-error.log
    CustomLog /var/log/apache2/cloud.leffringo.com-access.log combined

    <Directory /var/www/nextcloud/>
        Options +FollowSymlinks
        AllowOverride All

        <IfModule mod_dav.c>
            Dav off
        </IfModule>

        SetEnv HOME /var/www/nextcloud
        SetEnv HTTP_HOME /var/www/nextcloud
    </Directory>
</VirtualHost>

Once you're done, save the file and exit the editor.

Next, run the a2ensite command below to enable the virtual host configuration nextcloud.conf. Then verify the overall Apache2 configuration via the apachectl command below.

sudo a2ensite nextcloud.conf
sudo apachectl configtest

You should see the output Syntax OK if you have correct and proper Apache configurations.

Now enter the following systemctl command to restart the apache2 service and apply the Nextcloud virtual host configuration.

sudo systemctl restart apache2

After the apache2 restarted, your Nextcloud installation should be accessible via an insecure HTTP protocol. Visit your Nextcloud domain name and you should get the installation page like this:

Securing Nextcloud with SSL/TLS Certificates

To add an additional security layer for your Nextcloud, you will set up HTTPS within your Apache2 virtual host configuration via Certbot. The Certbot is a command-line tool for generating free SSL/TLS certificates from Letsencrypt and comes with an additional plugin that allows you to configure HTTPS automatically for multiple web servers.

Run the apt install command below to install Certbot and Certbot apache plugin. Input y, when prompted for confirmation, and press, ENTER to proceed.

sudo apt install certbot python3-certbot-apache

Now run the certbot command below to generate SSL/TLS certificates for your Nextcloud domain name and automatically configure HTTPS within the Apache2 virtual host. Be sure to change the domain name and the email address within the following command.

sudo certbot --apache --agree-tos --redirect --hsts --staple-ocsp --email user@hwdomain.io -d nextcloud.hwdomain.io

Once the process is finished, the Nextcloud domain name should be configured with HTTPS, which is managed by the Certbot Apache plugin. And the SSL/TLS certificates are located at /etc/letsencrypt/live/domain-name.com/ directory.

Installing Nextcloud

In this section, you will start the Nextcloud installation from your web browser. In this process, you will also create the admin user for Nextcloud.

Launch your web browser and visit the domain name of your Nextcloud installation (i.e: http://nextcloud.hwdomain.io/). You should automatically be redirected to a secure HTTPS connection and will be asked to create an administrator user for Nextcloud.

Input the new admin user and password for your Nextcloud. You can also set up a custom data directory or leave it as default.

Next, scroll to the bottom page and input the details database name, user, and password. Then click Finish Setup to complete the installation.

Once installation is completed, you should get the Nextcloud recommendation to install some of Nextcloud apps. Click Skip to install it later.

Now you should see the user dashboard like the following:

Now click on the folder icon to get the file manager of Nextcloud.

Lastly, click the user icon on the left menu and select Administration Settings.

Within the Administration section, click Overview. You should get information on your Nextcloud version and some recommendations that you can apply to your Nextcloud, including some security recommendations and performance optimizations.

Basic Performance Tuning for Nextcloud

In the following steps, you will add settings to your Nextcloud installation by enabling memory cache via OPCache and setting up cron via crontab.

Open the default Nextcloud configuration /var/www/nextcloud/config/config.php using the nano editor command below.

sudo nano /var/www/nextcloud/config/config.php

Within the $CONFIG = array section, add the new configuration below to enable the memory caching for Nextcloud.

<?php
$CONFIG = array (
....
  # Additional configuration
  'memcache.local' => '\OC\Memcache\APCu',
);

Save the changes and close the file when you're done.

Next, run the following command to create a new crontab that will be used to run the Nextcloud crontab script. The parameter -u www-data is used because the Apache2 web server is running on top of that user.

sudo crontab -u www-data -e

Add the following configuration to the crontab file.

*/5  *  *  *  * php -f /var/www/nextcloud/cron.php

Save and exit the file when finished.

Verify the list crontab for the user www-data using the following command. Ensure you have the crontab script that you've added.

sudo crontab -u www-data -l

Conclusion

You're all set! You've completed the installation of Nextcloud on your Debian system. You've installed Nextcloud with Apache2 web server, PHP 8.2, and the MariaDB database server. You've also secured your Nextcloud with UFW (Uncomplicated Firewall) and SSL/TLS certificates via Certbot and Letsencrypt.

With that all setup, you can now use Nextcloud to store your documents securely or add third-party data storage to your Nextcloud.

[How-To] Configure Nextcloud after Installation

Purpose

This document aims to make config adjustments to get ride of all errors in Nextcloud after initial installation and setup. 

Prerequisites

List of prerequisites:

Nextcloud Configuration 

Step 1: Configure Nextcloud Config.php

First, run the following to change to the correct directory:

cd /var/www/nextcloud/config

Next, run the following command to install redis:

sudo apt update
sudo apt install redis-server php-redis

Now, run this command to enable redis on startup:

sudo systemctl enable redis-server

Next, run the following command to edit the config.php file:

sudo nano config.php

Once in the file, work off of this below golden image, making sure not to change anything values already set that are *** out of this golden config:

<?php
$CONFIG = array (
  'instanceid' => '******',
  'passwordsalt' => '******',
  'secret' => '******',
  'trusted_domains' =>
  array (
    0 => 'cloud.dev.stretchpowered.com',
  ),
  'trusted_proxies' =>
  array (
    0 => '10.10.30.100',
  ),
  'overwritehost' => 'cloud.dev.stretchpowered.com',
  'datadirectory' => '/var/www/nextcloud/data',
  'dbtype' => 'mysql',
  'version' => '29.0.2.2',
  'overwrite.cli.url' => 'https://cloud.dev.stretchpowered.com',
  'overwriteprotocol' => 'https',
  'dbname' => 'nextcloud_db',
  'dbhost' => 'localhost',
  'dbport' => '',
  'dbtableprefix' => 'oc_',
  'mysql.utf8mb4' => true,
  'dbuser' => 'nextclouduser',
  'dbpassword' => '******',
  'installed' => true,
  'memcache.local' => '\\OC\\Memcache\\APCu',
'memcache.locking' => '\\OC\\Memcache\\Redis',
'redis' => [
    'host' => 'localhost',
    'port' => 6379,
    // Optional for password-protected Redis instances
    // 'password' => '******',
    'timeout' => 0.0,
    'read_timeout' => 0.0,
    'dbindex' => 0,
],
  'default_phone_region' => 'US',
  'mail_from_address' => 'nextcloud-leffringo',
  'mail_smtpmode' => 'smtp',
  'mail_sendmailmode' => 'smtp',
  'mail_domain' => 'outlook.com',
  'mail_smtphost' => 'smtp-mail.outlook.com',
  'mail_smtpport' => '587',
  'mail_smtpauth' => 1,
  'mail_smtpname' => 'nextcloud-leffringo@outlook.com',
  'mail_smtppassword' => '******',
  'maintenance_window_start' => 7,
  'maintenance' => false,
  'theme' => '',
  'loglevel' => 2,
);

Next, run the following command to restart Apache web server:

sudo systemctl restart apache2

Once you've made all the changes to match the golden config, move on to step 2.

Step 2: Configure Apache2 nextcloud.conf

Run the following command to go to the correct directory:

cd /etc/apache2/sites-available

Run the following command to edit the nextcloud.conf file:

sudo nano nextcloud.conf

Make the following changes if anything is different, being careful not to mess with domain settings for the environment you are working with:

<VirtualHost *:80>
    ServerName cloud.dev.stretchpowered.com
    DocumentRoot /var/www/nextcloud/

    # log files
    ErrorLog /var/log/apache2/cloud.dev.stretchpowered.com-error.log
    CustomLog /var/log/apache2/cloud.dev.stretchpowered.com-access.log combined

    <Directory /var/www/nextcloud/>
        Options +FollowSymlinks
        AllowOverride All

        <IfModule mod_dav.c>
            Dav off
        </IfModule>

        SetEnv HOME /var/www/nextcloud
        SetEnv HTTP_HOME /var/www/nextcloud
    </Directory>
</VirtualHost>

Once you've matched the golden config, move on to step 3.

Step 3: Configure .htaccess Config

Run the following command to change to the correct directory:

cd /var/www/nextcloud

Run the following command to enable mod_rewrite on apache2:

sudo a2enmod rewrite

Run the following command to edit the config file:

sudo nano .htaccess

Most of this document default is fine, just scroll down toward the bottom and add lines missing from this section:

<IfModule mod_rewrite.c>
  RewriteEngine on
  RewriteCond %{HTTP_USER_AGENT} DavClnt
  RewriteRule ^$ /remote.php/webdav/ [L,R=302]
  RewriteRule .* - [env=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
  RewriteRule ^\.well-known/host-meta /nextcloud/public.php?service=host-meta [QSA,L]
  RewriteRule ^\.well-known/host-meta\.json /nextcloud/public.php?service=host-meta-json [QSA,L]
  RewriteRule ^\.well-known/carddav /remote.php/dav/ [R=301,L]
  RewriteRule ^\.well-known/caldav /remote.php/dav/ [R=301,L]
  RewriteRule ^\.well-known/webfinger /nextcloud/public.php?service=webfinger [QSA,L]
  RewriteRule ^remote/(.*) remote.php [QSA,L]
  RewriteRule ^(?:build|tests|config|lib|3rdparty|templates)/.* - [R=404,L]
  RewriteRule ^\.well-known/(?!acme-challenge|pki-validation) /index.php [QSA,L]
  RewriteRule ^ocm-provider/?$ index.php [QSA,L]
  RewriteRule ^(?:\.(?!well-known)|autotest|occ|issue|indie|db_|console).* - [R=404,L]
</IfModule>

Once you have added these missing lines, move on to step 4.

Step 4: Configure nginx reverse proxy config

Run the following command to change to the correct directory (on the reverse proxy nginx box, not nextcloud):

cd /etc/nginx/conf.d

Run the following command to edit the correct conf file name:

sudo nano cloud.dev.stretchpowered.com.conf

Match this config with the items below, making sure not to mess with the SSL and domain settings you already have specific to the environment. 

server {
        server_name cloud.dev.stretchpowered.com;
        client_max_body_size 64000m;
        location / {
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-Proto https;
        proxy_set_header X-Forwarded-Host $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://10.30.20.151:80;

        # Adjusted timeout settings
        proxy_connect_timeout 600s;
        proxy_send_timeout 600s;
        proxy_read_timeout 600s;
        send_timeout 600s;

        # Adjusted buffer settings
        proxy_buffer_size 128k;
        proxy_buffers 4 256k;
        proxy_busy_buffers_size 256k;
        proxy_temp_file_write_size 256k;
        }

        add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;

    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/cloud.dev.stretchpowered.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/cloud.dev.stretchpowered.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}
server {
    if ($host = cloud.dev.stretchpowered.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


        listen 80;
        server_name cloud.dev.stretchpowered.com;
    return 404; # managed by Certbot


}

Once you've matched these to the golden config, move on to step 5.

Step 5: Configure apcu Config

First lets make sure apcu is running under the correct version of PHP:

php -m | grep apcu

This should return the word apcu. Once you have that confirmed, run the following to edit the config:

sudo nano /etc/php/8.2/mods-available/apcu.ini

Once editing, add the following lines:

extension=apcu.so
apc.enable_cli=1

Save and exit that config file. Then, run the following to enable the apcu module for PHP 8.2:

sudo phpenmod apcu

Then, restart the web server:

sudo systemctl restart apache2

Then, if you have this error or just as a good check, run this command to make sure no database entries are missing:

sudo -u www-data php /var/www/nextcloud/occ db:add-missing-indices

That is it for this step, move on to step 6.

Step 6: Clear Nextcloud Error Log

Run the following command to become root as you need to be for this:

sudo su -l

Run the following command to change to the correct directory:

cd /var/www/nextcloud/data

Run the following command to remove the nextcloud config file:

rm -f nextcloud.log

Next, change dirs to this:

cd /var/www/nextcloud

Then, run this:

sudo -u www-data php occ maintenance:repair --include-expensive

With that, you've completed the initial config. Refresh your nextcloud instance in browser on admin tab to see if you have the famous green check mark. 

NextCloud Configuration

[How-To] Move Nextcloud Data Directory

Purpose

The purpose of this document is to show how to move the data directory of a nextcloud server. 

Prerequisites

List of prerequisites:

Data Directory Move

Step 1: Shut Down Nextcloud Web Server

First, we need to stop Apache so nextcloud is not active. Do this with the following command:

sudo systemctl stop apache2

Step 2: Move Data Directory Contents

Next, we have to move the contents of the data directory. First, become root:

sudo su -l

Then, use the copy command to move everything from the original dir to the target dir for new data:

cp -r /var/www/nextcloud/data /mnt/nc-data/

Step 3: Change Data Directory in Nextcloud Config

Next, change the data directory in the nextcloud config:

sudo nano /var/www/nextcloud/config/config.php
'datadirectory' => '/mnt/nc-data/data',

Around line 15, you should see like above, change this to the new data directory.

Step 4: Change Owner Permissions

Next, we need to update www-data to be the owner of the new data dir:

sudo chown -R www-data:www-data /mnt/nc-data/data

Step 5: Start Nextcloud Web Server

Finally, start the nextcloud web server for the first time with the new data directory:

sudo systemctl start apache2

Once the web server has started, try to browse to the URL. If everything is good, you'll get to login page. If it says something about a file not existing, you've not done things in order. After getting past login, go to admin settings to check for errors. It will likely complain about the cronjob not being able to run. Just run it manually once like this then it should be good going forward:

sudo -u www-data php -f /var/www/nextcloud/cron.php

Once everything is good to go with no errors and you have backups, remove the old data directory:

sudo rm -rf /var/www/nextcloud/data

NextCloud Configuration

[How-To] Add LDAP/AD Authentication to Nextcloud

Purpose

This will show you how to add LDAP/AD auth to the nextcloud server. 

Prerequisites

List of prerequisites:

LDAP Implementation

Step 1: Update and Install Modules

Run this line to update your server CLI side:

sudo apt update

Now run this command to install the php-ldap module:

sudo apt install php-ldap -y

Next, reload Apache so that the updated library can be exposed to Nextcloud:

sudo systemctl reload apache2

Now you have the needed mods and can move on to GUI steps.

Step 2: Add the LDAP App in the GUI

First, browse to your Nextcloud Instance in web UI. Log in and go to administrative settings in the top right corner. Then, browse to disabled apps. Look for "LDAP user and group backend" and enable it. 

Step 3: Configure the LDAP App

After you enable the app, in the admin tab, you'll see "LDAP/AD Integration", select it. There are 4 tabs to configure:

  1. The first tab is the Server tab. It will set up what LDAP/AD servers you are pointing to. Use the IP address or the DNS name for each DC, and add them as separate servers with the plus button. Once they are added, add an account dedicated to servicing user lookups for this app and its password. Then finally, add a Base DN for user lookup. 
  2. The second tab is for user configuration. Everything here can be left default.
  3. The third tab is for configuring Login Attributes. The only thing to change here is to to check the email box and the username to allow users to sign in with either option. 
  4. The fourth tab is to configure security groups for nextcloud users. Use the drop-down to select the group and hit save. Make sure the configuration shows as OK and green status.

[How-To] Format and Mount Data Drive on Debian Server

Purpose

This doc shows how to take an additional virtual hard drive on a linux vm and make a mount point on the main drive with it for nextcloud data. 

Prerequisites

List of prerequisites:

Instructions

Step 1: Create a Partition on the New Drive

  1. Use fdisk to partition the drive: 
    sudo fdisk /dev/sdb
  2. Inside the fdisk utility:
    • Press n to create a new partition.
    • Select p for a primary partition.
    • Accept the default values for the first and last sectors (this will use the entire disk).
    • Press w to write the changes and exit.

Step 2: Format the Partition

  1. Verify the partition name (it should be /dev/sdb1 after partitioning): 
    lsblk
  2. Format the partition with the ext4 filesystem: 
    sudo mkfs.ext4 /dev/sdb1

Step 3: Mount the Partition

  1. Create a directory to mount the drive (e.g., /mnt/nextcloud-data): 
    sudo mkdir /mnt/nextcloud-data
  2. Mount the partition to the directory: 
    sudo mount /dev/sdb1 /mnt/nextcloud-data

Step 4: Make the Mount Persistent

  1. Get the UUID of the new partition: 
    sudo blkid /dev/sdb1
    Example output: 
    /dev/sdb1: UUID="abcd-1234-efgh-5678" TYPE="ext4"
  2. Edit the /etc/fstab file: 
    sudo nano /etc/fstab
  3. Add the following line to the file: 
    UUID=abcd-1234-efgh-5678 /mnt/nextcloud-data ext4 defaults 0 2
  4. Save and exit the editor.

Step 5: Update Nextcloud Configuration

  1. Move existing Nextcloud data to the new drive:

    sudo rsync -a /path/to/current/nextcloud/data/ /mnt/nextcloud-data/

    Replace /path/to/current/nextcloud/data/ with the actual path to your current Nextcloud data directory.

  2. Update the datadirectory path in Nextcloud's configuration file (config.php):

    sudo nano /var/www/nextcloud/config/config.php

    Find the datadirectory line and change it to:

    'datadirectory' => '/mnt/nextcloud-data',

  3. Set the correct permissions:

    sudo chown -R www-data:www-data /mnt/nextcloud-data

Step 6: Restart Services

  1. Restart the web server and PHP:

    sudo systemctl restart apache2

  2. Ensure everything works:

    • Log in to your Nextcloud instance.
    • Verify that the new data directory is being used.
