To change the data storage path for Nextcloud, you need to follow a series of steps. This process involves moving your existing data directory to a new location and updating Nextcloud's configuration to point to the new location. Here’s a detailed guide on how to do this:
### 1. **Prepare the New Data Directory**
1. **Create the New Data Directory:**
First, create the new directory where you want to store your Nextcloud data:
```bash
sudo mkdir -p /path/to/new/nextcloud_data
```
Replace `/path/to/new/nextcloud_data` with the desired path.
2. **Set Correct Permissions:**
Next, set the proper ownership and permissions for the new directory:
```bash
sudo chown -R www-data:www-data /path/to/new/nextcloud_data
sudo chmod -R 755 /path/to/new/nextcloud_data
```
### 2. **Move Existing Data**
1. **Stop the Web Server:**
Before moving the data, stop the web server to ensure no files are being accessed:
```bash
sudo systemctl stop apache2
```
2. **Move the Data:**
Move the existing Nextcloud data to the new directory:
```bash
sudo mv /var/www/nextcloud/data/* /path/to/new/nextcloud_data/
```
Ensure the original data directory is empty:
```bash
sudo rmdir /var/www/nextcloud/data
```
### 3. **Update Nextcloud Configuration**
1. **Edit the Configuration File:**
Open the Nextcloud configuration file:
```bash
sudo nano /var/www/nextcloud/config/config.php
```
2. **Update the `datadirectory` Path:**
Find the line with `'datadirectory'` and update it to the new path:
```php
'datadirectory' => '/path/to/new/nextcloud_data',
```
3. **Save and Close the File:**
Save the changes (`CTRL+O`) and exit the editor (`CTRL+X`).
### 4. **Restart the Web Server**
Restart Apache to apply the changes:
```bash
sudo systemctl start apache2
```
### 5. **Verify the New Data Directory**
Log in to your Nextcloud web interface and verify that everything is working correctly. Check if you can see your files and upload new ones without issues.
### Optional: **Update the Old Data Directory (if necessary)**
If you want to keep the old directory as a backup or for any other reason, ensure it's removed or archived securely:
1. **Check Old Directory:**
Verify the old data directory is empty:
```bash
sudo ls /var/www/nextcloud/data
```
2. **Remove or Archive the Old Directory:**
```bash
sudo rm -rf /var/www/nextcloud/data
```
### Troubleshooting
- **Permissions Issues:** If you encounter permissions issues, double-check that the `www-data` user has the correct ownership and permissions on the new data directory.
- **Check Logs:** If Nextcloud is not functioning as expected, check the Nextcloud logs (`/var/www/nextcloud/data/nextcloud.log`) and Apache error logs for clues.
- **Database Update:** If you have issues accessing files or the Nextcloud interface, ensure the database is updated properly. Sometimes, a Nextcloud upgrade or change in the data path might require a database scan or repair. You can do this using the Nextcloud command-line tool:
```bash
sudo -u www-data php /var/www/nextcloud/occ files:scan --all
```
By following these steps, you should be able to change the data storage path for Nextcloud successfully.
