  • Raspberry PI based installations proved to work, see wiki page here.
  • For Windows based installations please read the wiki. There are closed issues about this subject, as this topic has been covered a lot.

Local install

First of all, if you're seeing the message system folder missing after launching your browser, that most likely means you have cloned the repository and have not built the project.

  1. Download the latest stable or pre-release for a specific branch from GitHub here. A repository clone will not work unless know how to build the project.
  2. Create/locate a new MySQL database to install Open Source Point of Sale into.
  3. Execute the file database/database.sql to create the tables needed.
  4. Unzip and upload Open Source Point of Sale files to the web-server.
  5. Open application/config/database.php and modify credentials to connect to your database if needed.
  6. Open application/config/config.php and swap the encryption key with your own.
  7. Go to your install public dir via the browser.
  8. Log in using
    • Username: admin
    • Password: pointofsale
  9. Enjoy!
  10. Oops, an issue? Please make sure you read the FAQ, wiki page, and you checked open and closed issues on GitHub. PHP display_errors is disabled by default. Create an application/config/.env file from the .env.example to enable it in a development environment.

Local install using Docker

OSPOS can be deployed using Docker on Linux, Mac, and Windows. Locally or on a host (server). This setup dramatically reduces the number of possible issues as all setup is now done in a Dockerfile. Docker runs natively on Mac and Linux. Windows requires WSL2 to be installed. Please refer to the Docker documentation for instructions on how to set it up on your platform.

Be aware that this setup is not suited for production usage! Change the default passwords in the compose file before exposing the containers publicly.

Start the containers using the following command

    docker-compose up

Nginx install using Docker

Since OSPOS version 3.3.0 the Docker installation offers a reverse proxy based on Nginx with a Let's Encrypt TLS certificate termination (aka HTTPS connection). Let's Encrypt is a free certificate issuer, requiring a special installation that this Docker installation would take care of for you. Any Let's Encrypt TLS certificate renewal will be managed automatically, therefore there is no need to worry about those details.

Before starting your installation, you should edit the docker/.env file and configure it to contain the correct MySQL/MariaDB and phpMyAdmin passwords (don't use the defaults!). You will also need to register to Let's Encrypt. Configure your host domain name and Let's Encrypt email address in the docker/.env file. The variable STAGING needs to be set to 0 when you are confident your configuration is correct so that Let's Encrypt will issue a final proper TLS certificate.

Follow local install steps, but instead use


Do not use below command on live deployments unless you want to tear everything down. All your disk content will be wiped!
