More information on applications in the dedicated section or in the nextcloud application catalogue: [apps.nextcloud.com](https://apps.nextcloud.com). Nextcloud is before a cloud service (like Seafile and others), it allows synchronization and file sharing on the Internet and between several terminals (computers, smartphone) but also with several people. ## Mobile and computer client software There are client software for all platforms. You can find them on the official nextcloud website: https://nextcloud.com/install/#install-clients ## Useful Manipulations & Problems Encountered ### Add storage space Solution I. allows you to add a link to a local or remote folder. Solution II. allows to move the main storage space of Nextcloud. #### I. Add an external storage space Parameter =>[Administration] External storage. At the bottom of the list you can add a folder (It is possible to define a subfolder using the `folder/subfolder` convention.) Select a storage type and specify the requested connection information. You can restrict this folder to one or more nextcloud users with the column `Available for`. With the gear you can allow or prohibit previewing and file sharing. Finally click on the check mark to validate the folder. #### II. Migrate Nextcloud data to a larger partition **Note**: The following assumes that you have a hard disk mounted on `/media/storage`. Refer to[this article](/external_storage) to prepare your system. **Note**: Replace `nextcloud` with the name of its instance, if you have several Nextcloud apps installed. First turn off the web server with the command: ```bash systemctl stop nginx ``` ##### Choice of location **Case A: Blank storage, exclusive to Nextcloud** For the moment only root can write to it in `/media/storage`, which means that NGINX and Nextcloud will not be able to use it. ```bash chown -R nextcloud:nextcloud /media/storage chmod 775 -R /media/storage ``` **Case B: Shared storage, data already present, Nextcloud data in a subfolder** If you want to use this disk for other applications, you can create a subfolder belonging to Nextcloud. ```bash mkdir -p /media/storage/nextcloud_data chown -R nextcloud /media/storage/nextcloud_data chmod 775 -R /media/storage/nextcloud_data ``` ##### Migrate data Migrate your data to the new disk. To do this *(be patient, it can take a long time)*: ```bash Case A: cp -ia /home/yunohost.app/nextcloud /media/storage Case B: cp -ia /home/yunohost.app/nextcloud /media/storage/nextcloud_data ``` The `i` option allows you to ask yourself what to do if there is a file conflict, especially if you overwrite an old Owncloud or Nextcloud data folder. To check that everything went well, compare what these two commands display (the content must be identical): ```bash ls -la /home/yunohost.app/nextcloud Case A: ls -al /media/storage Case B: ls -al /media/storage/nextcloud_data/nextcloud ``` ##### Configure Nextcloud To inform Nextcloud of its new directory, modify the `/var/www/nextcloud/config/config.php` file with the command: ```bash nano /var/www/nextcloud/config/config.php ``` Look for the line: ```bash 'datadirectory' => '/home/yunohost.app/nextcloud/data', ``` That you modify: ```bash CASE A:'datadirectory' =>'/media/storage', CASE B:'datadirectory' =>'/media/storage/nextcloud_data/nextcloud/data', ``` Back up with `ctrl+x` then `y` or `o` (depending on your server locale). Restart the web server: ```bash systemctl start nginx ``` Add the.ocdata file ```bash CASE A: nano /media/storage/.ocdata CASE B: nano /media/storage/nextcloud_data/nextcloud/data/.ocdata ``` Add a space to the file to be able to save it Back up with `ctrl+x` then `y` or `o` (depending on your server locale). Run a scan of the new directory by Nextcloud: ```bash cd /var/www/nextcloud sudo -u nextcloud php7.3 occ files:scan --all ``` It's over now. Now test if everything is fine, try connecting to your Nextcloud instance, upload a file, check its proper synchronization. ### Nextcloud and Cloudflare If you use Cloudflare for your DNS, *which may be useful if you have a dynamic IP*, you will most likely have authentication problems with the Nextcloud application. On the Internet many people propose to create a rule that disables all options related to security and Cloudflare speed for the URL pointing to your Nextcloud instance. Although it works, it is not the optimal solution. I propose, certainly to create a rule for the URL pointing to your Nextcloud instance but to disable only 2 options. So here's how: #### Cloudflare Page Rules In the Cloudflare control panel select your domain and find Page Rules the URL in your address bar will look like this: https://dash.cloudflare.com/*/domain.tld/page-rules ##### Add a rule The rule to be added must apply to the URL of your Nextcloud instance either: - `https://nextcloud.domain.tld/**` if you use a subdomain - `https://domain.tld/nextcloud/*` if you have deployed Nextcloud in a directory The options to disable (Off) are: - Rocket Loader - Email Obfuscation Save and clean your caches (Cloudflare, browser...) and that's it. ## Third Party Applications - [Calendrier](/app_nextcloud_calendar) - [Contact](/app_nextcloud_contact) - [KeeWeb](/app_nextcloud_keeweb) - [Carnet](/app_nextcloud_carnet) ## Useful links - Official website: [nextcloud.com](https://nextcloud.com/) - Application catalogue for Nextcloud: [apps.nextcloud.com](https://apps.nextcloud.com/)
