Install NextCloud

NextCloud prerequisites

1. NextCloud needs a web server with Apache, MySQL (MariaDB) and PHP, and it also needs a few PHP modules. Use the following commands to install everything:

sudo apt install apache2 mariadb-server libapache2-mod-php
sudo apt install php-gd php-json php-mysql php-curl php-mbstring php-intl php-imagick php-xml php-zip

NextCloud installation

You now need to download and extract the NextCloud archive:

1. Go to the Apache web folder.

cd /var/www/html

2. Get the latest NextCloud from here (i.e. nextcloud-15.0.8.zip or .tar.bz2 archive).

sudo wget https://download.nextcloud.com/server/releases/nextcloud-15.0.8.zip

3. Extract the file with unzip.

sudo unzip nextcloud-15.0.8.zip

4. As we use root to extract files, we need to change the folder permissions to allow Apache to access it:

sudo chmod 750 nextcloud -R
sudo chown www-data:www-data nextcloud -R

MySQL configuration

After the MariaDB server installation, it creates a root user you can use only from the command line.

1. We will create a new user and a dedicated database for NextCloud. Connect to MySQL with root.

sudo mysql

2. Create the new user. Replace “password” by a strong password.

CREATE USER 'nextcloud' IDENTIFIED BY 'password';

3. Create the new database

CREATE DATABASE nextcloud;

4. Give all permissions to the new user on this database. Same thing here, just replace “password” with the previous password.

GRANT ALL PRIVILEGES ON nextcloud.* TO 'nextcloud'@localhost IDENTIFIED BY ‘password’;

5. Save and exit.

FLUSH PRIVILEGES;
quit

NextCloud configuration

1. Open the following URL in your browser: https://[IP]/nextcloud. Replace the “IP” with the Raspberry Pi IP address.

2. A form will show up. Choose a username and password for NextCloud.

3. Enter the credentials we just created in MySQL:

– User: nextcloud – Password: “password” (your password) – Database: nextcloud – Host: localhost

4. Then click “Finish setup” and wait a few minutes to be redirected to the NextCloud home page.

Allow local users to access NextCloud Server

1. Edit the configuration file of the NextCloud server.

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

2. Add the local domain of Pi in trusted_domains (e.g. 192.168.0.101).

...
'trusted_domains' =>
array (
	0 => '192.168.0.101',
),
...
