To install Nextcloud and host your files on a Linux server (like the one running Zorin OS), follow these step-by-step instructions. This guide will cover the installation of Nextcloud using a LAMP stack (Linux, Apache, MySQL/MariaDB, PHP).
### Step 1: Update Your System
Before installing any packages, it's good practice to update your system:
```bash
sudo apt update
sudo apt upgrade -y
```
### Step 2: Install Apache Web Server
Nextcloud requires a web server, and we'll use Apache in this setup.
```bash
sudo apt install apache2 -y
```
Start and enable Apache to run on boot:
```bash
sudo systemctl start apache2
sudo systemctl enable apache2
```
### Step 3: Install MySQL/MariaDB
Nextcloud uses a database to store its data. You can choose between MySQL and MariaDB.
Install MariaDB (recommended):
```bash
sudo apt install mariadb-server mariadb-client -y
```
Secure the MariaDB installation:
```bash
sudo mysql_secure_installation
```
During the secure installation, you’ll be prompted to:
- Enter the root password (if it's the first time, press Enter for no password).
- Set a root password.
- Remove anonymous users.
- Disallow root login remotely.
- Remove test databases.
- Reload privilege tables.
### Step 4: Create a Database for Nextcloud
Log in to MySQL/MariaDB as the root user:
```bash
sudo mysql -u root -p
```
Create a database and user for Nextcloud:
```sql
CREATE DATABASE nextcloud;
CREATE USER 'maverick'@'localhost' IDENTIFIED BY 'strong_password';
GRANT ALL PRIVILEGES ON nextcloud.* TO 'maverick'@'localhost';
FLUSH PRIVILEGES;
EXIT;
```
Replace `strong_password` with a secure password.
### Step 5: Install PHP and Required Extensions
Nextcloud is built with PHP, so you'll need to install PHP and some extensions.
```bash
sudo apt install php libapache2-mod-php php-mysql php-gd php-json php-curl php-mbstring php-intl php-imagick php-xml php-zip php-xmlrpc php-gmp -y
```
### Step 6: Download and Install Nextcloud
Go to the `/var/www/` directory:
```bash
cd /var/www/
```
Download the latest version of Nextcloud:
```bash
sudo wget https://download.nextcloud.com/server/releases/nextcloud-27.0.0.zip
```
Extract the downloaded archive:
```bash
sudo apt install unzip -y
sudo unzip nextcloud-27.0.0.zip
```
Set the correct permissions:
```bash
sudo chown -R www-data:www-data /var/www/nextcloud/
sudo chmod -R 755 /var/www/nextcloud/
```
### Step 7: Configure Apache for Nextcloud
Create a new Apache configuration file for Nextcloud:
```bash
sudo nano /etc/apache2/sites-available/nextcloud.conf
```
Add the following content to the file:
```apache
<VirtualHost *:80>
DocumentRoot /var/www/nextcloud/
ServerName your_domain_or_IP
<Directory /var/www/nextcloud/>
Require all granted
AllowOverride All
Options FollowSymLinks MultiViews
<IfModule mod_dav.c>
Dav off
</IfModule>
</Directory>
ErrorLog ${APACHE_LOG_DIR}/nextcloud_error.log
CustomLog ${APACHE_LOG_DIR}/nextcloud_access.log combined
</VirtualHost>
```
Replace `your_domain_or_IP` with your domain name or server IP address.
Enable the new site and the necessary Apache modules:
```bash
sudo a2ensite nextcloud.conf
sudo a2enmod rewrite headers env dir mime
sudo systemctl restart apache2
```
### Step 8: Complete the Nextcloud Installation via Web Interface
Open your web browser and navigate to `http://your_domain_or_IP`. You should see the Nextcloud setup page.
1. **Create an Admin Account:**
- Enter a username and password for the admin account.
2. **Database Configuration:**
- Database user: `maverick`
- Database password: The password you set earlier
- Database name: `nextcloud`
- Database host: `localhost`
3. **Data Folder:**
- The default is `/var/www/nextcloud/data/`, but you can change this if needed.
Click "Finish Setup."
### Step 9: Secure Nextcloud with HTTPS (Optional but Recommended)
To secure your Nextcloud installation, you should use HTTPS. If you have a domain name, you can use Let's Encrypt to get a free SSL certificate.
1. **Install Certbot:**
```bash
sudo apt install certbot python3-certbot-apache -y
```
2. **Obtain an SSL Certificate:**
```bash
sudo certbot --apache -d your_domain_or_IP
```
3. **Follow the prompts to set up HTTPS.**
### Step 10: Access Nextcloud and Start Hosting Files
Now that Nextcloud is set up, you can start using it to host files. You can upload files via the web interface, or sync them using the Nextcloud desktop or mobile apps.
### Optional: Install and Configure the Nextcloud Client
Nextcloud provides clients for syncing files across your devices. You can download and install the client from the official Nextcloud website for Linux, Windows, macOS, Android, and iOS.
### Conclusion
You've successfully installed and configured Nextcloud on your Linux server. You can now host and manage files securely and access them from any device.
The error you're encountering typically occurs when the database user (`maverick@localhost`) doesn't have the necessary permissions to connect to the database, or when the password is incorrect. Here's how you can resolve this issue:
### Step 1: Verify Database User Permissions
1. **Log in to MySQL/MariaDB as the root user:**
```bash
sudo mysql -u root -p
```
2. **Check the user privileges:**
Run the following command to see if the `maverick@localhost` user exists and has the necessary privileges:
```sql
SELECT user, host FROM mysql.user;
```
If you see `maverick` listed with `localhost` as the host, proceed to the next step. If not, create the user or adjust permissions.
3. **Grant necessary privileges:**
Grant full privileges to the `maverick@localhost` user for the Nextcloud database:
```sql
GRANT ALL PRIVILEGES ON nextcloud.* TO 'maverick'@'localhost' IDENTIFIED BY 'your_password';
FLUSH PRIVILEGES;
EXIT;
```
Replace `your_password` with the actual password for the `maverick` user.
### Step 2: Test Database Connection
Before proceeding with the Nextcloud setup again, test the connection to ensure that the user can access the database:
```bash
mysql -u maverick -p
```
If you can log in successfully, the user has the correct privileges.
### Step 3: Restart Apache
Restart Apache to apply any changes:
```bash
sudo systemctl restart apache2
```
### Step 4: Retry Nextcloud Installation
Navigate back to your Nextcloud setup page (`http://your_domain_or_IP`) and try creating the admin user again. Ensure the database configuration fields are correctly filled:
- **Database user:** `maverick`
- **Database password:** `your_password`
- **Database name:** `nextcloud`
- **Database host:** `localhost`
### Conclusion
By granting the correct privileges and ensuring the user can connect to the database, the issue should be resolved, allowing you to proceed with the Nextcloud installation.

The storage usage in Nextcloud comes from the data stored within the platform, including files, photos, videos, and documents uploaded by users. Here’s a breakdown of where this storage usage originates and how it’s managed:
### 1. **User Files and Data**
- **Uploaded Files**: All files uploaded by users (documents, images, videos, etc.) are stored in the Nextcloud data directory.
- **Shared Files**: Files shared with other users or groups are stored in the same directory but are accessible to multiple users.
- **App Data**: Certain Nextcloud apps may also store data (e.g., calendar, contacts, etc.) in the Nextcloud data directory.
### 2. **Data Directory**
- **Default Data Directory**: By default, all user data in Nextcloud is stored in the `/var/www/nextcloud/data/` directory. This directory is specified during the Nextcloud installation.
- **Custom Data Directory**: If you specified a custom data directory during setup, the data would be stored in that location instead. The storage usage includes all files within this directory.
### 3. **Database Storage**
- **Metadata and App Data**: Nextcloud uses a database (MariaDB, MySQL, or PostgreSQL) to store metadata about the files (like file names, sizes, permissions) and data from certain apps (like calendars, contacts, etc.). The storage usage you see in the database is related to this metadata and app data.
### 4. **External Storage (if configured)**
- **External Storage Options**: Nextcloud can be connected to external storage solutions like Amazon S3, Google Drive, or other network-attached storage (NAS) devices. Files stored on these external sources contribute to the overall storage usage as seen by Nextcloud, but the data physically resides on the external service.
- **Mounting External Storage**: If you’ve configured external storage in Nextcloud, the files stored there will also be counted towards your storage usage, but they are not stored on the local server's filesystem.
### 5. **Temporary Files and Caching**
- **Temporary Uploads**: During file uploads, temporary files might be created, contributing to storage usage until the upload is complete.
- **Previews and Thumbnails**: Nextcloud generates previews and thumbnails for images and videos, which are stored in the data directory and contribute to storage usage.
### 6. **Backup Files**
- **Versions and Trash**: Nextcloud has a file versioning system and trash bin functionality. Old versions of files and deleted files (until permanently deleted) are stored in the data directory, contributing to the storage usage.
### 7. **System Logs**
- **Log Files**: System logs, including access logs, error logs, and app logs, are stored on the server and contribute to overall storage usage. These are typically stored in the `/var/log/` directory, but they are separate from the Nextcloud data directory.
### How to Identify Where Storage is Being Used
To determine where storage is being used:
1. **Check User Data**:
- Look at each user's storage in the data directory (`/var/www/nextcloud/data/username/`) to see how much space their files are taking up.
2. **Examine External Storage**:
- If you’re using external storage, check the usage on those services directly or through the Nextcloud interface.
3. **Database Size**:
- Use `phpMyAdmin` or a command line to check the size of your Nextcloud database, which stores metadata and app data.
4. **Log Files**:
- Check the `/var/log/` directory for large log files that might be consuming space.
5. **Temporary and Cache Files**:
- Temporary files and cache files are usually in the Nextcloud data directory under subdirectories like `cache` or `tmp`.
### Conclusion
The storage used by Nextcloud comes from the combination of user files, database storage, external storage, temporary files, logs, and other app data. Understanding where your storage is being utilized can help you manage and optimize your Nextcloud instance effectively.
