Installing ONLYOFFICE Docs 📦

You will need an instance of ONLYOFFICE Docs (Document Server) that is resolvable and connectable both from Nextcloud and any end clients. ONLYOFFICE Document Server must also be able to POST to Nextcloud directly.

ONLYOFFICE Document Server and Nextcloud can be installed either on different computers, or on the same machine. If you use one machine, set up a custom port for Document Server as by default both ONLYOFFICE Document Server and Nextcloud work on port 80.

You can install free Community version of ONLYOFFICE Docs or scalable Enterprise Edition.

To install free Community version, use Docker (recommended) or follow these instructions for Debian, Ubuntu, or derivatives.

To install Enterprise Edition, follow instructions here.

Community Edition vs Enterprise Edition comparison can be found here.

To use ONLYOFFICE behind a proxy, please refer to this article.

You can also use our Docker installation to install pre-configured Document Server (free version) and Nextcloud with a couple of commands.

Alternatively, you can opt for ONLYOFFICE Docs Cloud which doesn't require downloading and installation. To get ONLYOFFICE Docs Cloud, get started here.

Installing ONLYOFFICE app for Nextcloud 📥

The Nextcloud administrator can install the app from the in-built application market. For that go to the user name and select Apps.

After that find ONLYOFFICE in the list of available applications and install it.

If the server with the Nextcloud installed does not have an Internet access, or if you need it for some other reason, the administrator can install the application manually. To start using ONLYOFFICE Document Server with Nextcloud, the following steps must be performed:

1. Go to the Nextcloud server apps/ directory (or some other directory used):

   cd apps/
   

2. Get the ONLYOFFICE app for Nextcloud. There are several ways to do that:

   a. Download the latest signed version from the official store for Nextcloud.

   b. Or you can download the latest signed version from the application release page on GitHub.

   c. Or you can clone the application source code and compile it yourself:

   git clone https://github.com/ONLYOFFICE/onlyoffice-nextcloud.git onlyoffice
   cd onlyoffice
   git submodule update --init --recursive
   

3. Run the build (only if you chose to clone on the previous step):

   npm install
   npm run build
   

4. Install Composer dependencies (only if you chose to clone on the step 2):

   composer install
   composer scope-dependencies
   rm -rf vendor/firebase
   composer dump-autoload
   

5. Change the owner to update the application right from Nextcloud web interface:

   chown -R www-data:www-data onlyoffice
   

6. In Nextcloud open the ~/settings/apps/disabled page with Not enabled apps by administrator and click Enable for the ONLYOFFICE application.

Configuring ONLYOFFICE app for Nextcloud 🛠️

There are three ways to configure ONLYOFFICE integration settings in Nextcloud.

User interface (UI)

Settings can be modified directly via the Nextcloud admin panel.

For example, in Nextcloud open the ~/settings/admin/onlyoffice page with administrative settings for ONLYOFFICE section. Enter the following address to connect ONLYOFFICE Document Server:

https://<documentserver>/

Where the documentserver is the name of the server with the ONLYOFFICE Document Server installed. The address must be accessible for the user browser and from the Nextcloud server. The Nextcloud server address must also be accessible from ONLYOFFICE Document Server for correct work.

Sometimes your network configuration might not allow the requests between installed Nextcloud and ONLYOFFICE Document Server using the public addresses. The Advanced server settings allows to set the ONLYOFFICE Document Server address for internal requests from Nextcloud server and the returning Nextcloud address for the internal requests from ONLYOFFICE Document Server. You need to enter them in the appropriate fields.

Starting from version 7.2, JWT is enabled by default and the secret key is generated automatically to restrict the access to ONLYOFFICE Docs and for security reasons and data integrity. Specify your own Secret key in the Nextcloud administrative configuration. In the ONLYOFFICE Docs config file, specify the same secret key and enable the validation.

occ commands

Use the occ commands to set ONLYOFFICE settings for Nextcloud in the following way:

php occ config:app:set onlyoffice {setting_key} --value={setting_value}

where {setting_key} is the key of the ONLYOFFICE integration setting, and {setting_value} is the corresponding value.

Watermark settings

Watermark settings (the watermark_* keys) are an exception: they are stored under the files app, not onlyoffice. Set them with files as the app id:

php occ config:app:set files {watermark_setting_key} --value={setting_value}

config.php

Directly define settings in the config/config.php file under the 'onlyoffice' array:

"onlyoffice" => array (
    {setting_key} => {setting_value},
)

where {setting_key} is the key of the ONLYOFFICE integration setting, and {setting_value} is the corresponding value.

The tables below list all available Nextcloud settings along with the supported configuration methods.

Customization settings

Watermark settings

Checking the connection ☑️

You can check the connection to ONLYOFFICE Document Server by using the following occ command:

occ onlyoffice:documentserver --check

You will see a text either with information about the successful connection or the cause of the error.

Advanced document permissions 🔒

The Advanced tab allows you to grant additional access rights only to those users specified in the Sharing tab without the ability to re-share the file. Depending on the chosen Custom permission option and the file type (docx, pptx, xlsx), you can grant different additional rights.

• If the DOCX file is shared with the Custom permission (Edit enabled, Share disabled) in the Sharing tab, you can set the given rights to only reviewing (Review only) or only commenting (Comment only) in the Advanced tab.
• If the XLSX file is shared with the Custom permission (Edit enabled, Share disabled) in the Sharing tab, you can set the given rights to only commenting (Comment only) or applying filtering for everyone (Global filter, which is enabled by default) in the Advanced tab.
• If the PPTX file is shared with the Custom permission (Edit enabled, Share disabled) in the Sharing tab, you can set the given rights to only commenting (Comment only) in the Advanced tab.
• If the PDF file is shared with the Custom permission (Edit enabled, Share disabled) in the Sharing tab, you can set the given rights to only filling out (Form Filling) in the Advanced tab.

How it works ⚙️

The ONLYOFFICE app follows the API documented here api.onlyoffice.com:

• When creating a new file, the user navigates to a document folder within Nextcloud and clicks the Document, Spreadsheet or Presentation item in the new (+) menu.

• The browser invokes the create method in the /lib/Controller/EditorController.php controller. This method adds the copy of the file from the assets folder to the folder the user is currently in.

• Or, when opening an existing file, the user navigates to it within Nextcloud and selects the Open in ONLYOFFICE menu option.

• A new browser tab is opened and the index method of the /lib/Controller/EditorController.php controller is invoked.

• The app prepares a JSON object with the following properties:

  • url - the URL that ONLYOFFICE Document Server uses to download the document;
  • callbackUrl - the URL that ONLYOFFICE Document Server informs about status of the document editing;
  • documentServerUrl - the URL that the client needs to respond to ONLYOFFICE Document Server (can be set at the administrative settings page);
  • key - the etag to instruct ONLYOFFICE Document Server whether to download the document again or not;

• Nextcloud takes this object and constructs a page from templates/editor.php template, filling in all of those values so that the client browser can load up the editor.

• The client browser makes a request for the javascript library from ONLYOFFICE Document Server and sends ONLYOFFICE Document Server the DocEditor configuration with the above properties.

• Then ONLYOFFICE Document Server downloads the document from Nextcloud and the user begins editing.

• ONLYOFFICE Document Server sends a POST request to the callbackUrl to inform Nextcloud that a user is editing the document.

• When all users and client browsers are done with editing, they close the editing window.

• After 10 seconds of inactivity, ONLYOFFICE Document Server sends a POST to the callbackUrl letting Nextcloud know that the clients have finished editing the document and closed it.

• Nextcloud downloads the new version of the document, replacing the old one.

Known issues ❓

• Adding the storage using the External storages app has issues with the co-editing in some cases. If the connection is made using the same authorization keys (the Username and password or Global credentials authentication type is selected), then the co-editing is available for the users. If different authorization keys are used (Log-in credentials, save in database or User entered, store in database authentication options), the co-editing is not available. When the Log-in credentials, save in session authentication type is used, the files cannot be opened in the editor.

• If you are using a self-signed certificate for your Document Server, Nextcloud will not validate such a certificate and will not allow connection to/from Document Server. This issue can be solved in two ways.

  You can check the 'Disable certificate verification (insecure)' box on the ONLYOFFICE administration page, Server settings section, within your Nextcloud.

  Another option is to change the Nextcloud config file manually. Locate the Nextcloud config file (/nextcloud/config/config.php) and open it. Insert the following section to it:

  'onlyoffice' => array (
      'verify_peer_off' => true
  )
  

  This will disable the certificate verification and allow Nextcloud to establish connection with Document Server.

  Please remember that this is a temporary insecure solution and we strongly recommend that you replace the certificate with the one issued by some CA. Once you do that, do not forget to uncheck the corresponding setting box or remove the above section from the Nextcloud config file.

• If the editors don't open or save documents after a period of proper functioning, the reason can be a problem in changing network settings or disabling any relevant services, or issues with the SSL certificate.

  To solve this, we added an asynchronous background task which runs on the server to check availability of the editors. It allows testing the connection between your Nextcloud instance and ONLYOFFICE Document Server, namely availability of server addresses and the validity of the JWT secret are being checked.

  If any issue is detected, the ONLYOFFICE app for Nextcloud (consequently, the ability to create and open files) will be disabled. As a Nextcloud admin, you will get the corresponding notification.

  This option allows you to avoid issues when the server settings become incorrect and require changes.

  By default, this background task runs once a day. If necessary, you can change the frequency. To do so, open the Nextcloud config file (/nextcloud/config/config.php). Insert the following section and enter the required value in minutes:

  'onlyoffice' => array (
      'editors_check_interval' => 3624
  )
  

  To disable this check running, enter 0 value.

• When accessing a document without download permission, file printing and using the system clipboard are not available. Copying and pasting within the editor is available via buttons in the editor toolbar and in the context menu.

• When a file is opened for editing in ONLYOFFICE while being simultaneously edited in other tools, changes may be overwritten or lost. To avoid conflicts and ensure smooth collaboration, we recommend using the Temporary File Lock application: https://apps.nextcloud.com/apps/files_lock. This helps prevent parallel editing and safeguards your work.
