It is possible to install Fusio either through composer or manually file download. Place the project into the www directory of the web server.


composer create-project fusio/fusio



You can either manually install Fusio with the steps below or you can also use the browser based installer at public/install.php. Note because of security reasons it is highly recommended to remove the installer script after the installation.

  • Adjust the configuration file

    Open the file .env in the Fusio directory and change the key FUSIO_URL to the domain pointing to the public folder. Also insert the database credentials to the FUSIO_DB_* keys.

  • Execute the installation command

    The installation script inserts the Fusio database schema into the provided database. It can be executed with the following command php bin/fusio install.

  • Create administrator user

    After the installation is complete you have to create a new administrator account. Therefor you can use the following command php bin/fusio adduser. Choose as account type “Administrator”.

You can verify the installation by visiting the psx_url with a browser. You should see a API response that the installation was successful. The backend is available at /apps/fusio/.

In case you want to install Fusio on a specific database you need to adjust the driver parameter at the configuration.php file:

  • pdo_mysql: MySQL
  • pdo_sqlite: SQLite
  • pdo_pgsql: PostgreSQL
  • sqlsrv: Microsoft SQL Server
  • oci8: Oracle
  • sqlanywhere: SAP Sybase SQL Anywhere


Fusio can be used on almost any setup which provides a web server and supports PHP. Please take a look at a platform specific setup guide:



At the endpoint apps/fusio/index.html you can login to the backend app. You should be able to login with the username (which you have entered for the adduser command) and the password which you have used. The following list covers the most login errors in case you are not able to login at the backend:

  • The javascript Backend-App uses the wrong API endpoint

    This can be tested with the browser developer console. If you login at the backend with no credentials the app should make an request to the /backend/token endpoint which should return a JSON response i.e.:

    { "error": "invalid_request", "error_description": "Credentials not available" }

    If this is the case your app is correctly configured. If this is not the case you need to adjust the endpoint url at /apps/fusio/index.htm i.e.:

    var fusioUrl = "http://localhost:8080/fusio/public/index.php/";
  • Apache module mod_rewrite is not activated

    In case you use Apache as web server you must activate the module mod_rewrite so that the public/.htaccess file is used. Besides clean urls it contains an important rule which tells Apache to redirect the Authorization header to Fusio otherwise Apache will remove the header and Fusio can not authenticate the user

  • Fusio API returns an error

    In this case Fusio can probably not write to the cache/ folder. To fix the problem you have to change the folder permissions so that the user of the web server can write to the folder. If there is another error message it is maybe a bug. Please report the issue to GitHub.


Fusio has a marketplace which contains a variety of apps for specific use cases. Every app can be directly installed from the backend app under System / Marketplace.


There are two parts of Fusio which you can update. The backend system and the backend app. The backend app is the AngularJS application which connects to the backend api and where you configure the system. The backend system contains the actual backend code providing the backend API and the API which you create with the system.


Fusio makes heavy use of composer. Because of that you can easily upgrade a Fusio system with the following composer command.

composer update fusio/impl

This has also the advantage that the version constraints of installed adapters are checked and in case something is incompatible composer will throw an error. It is also possible to simply replace the vendor folder with the folder from the new release. In either case you have to run the following command after you have updated the vendor folder:

php bin/fusio install

This gives Fusio the chance to adjust the database schema in case something has changed with a new release.


All apps can be updated at the Marketplace panel of the backend app. There you can simply use the update button to receive the latest version of the app.
