How to Install Superset on NixOS
Superset is a modern, open-source data visualization and exploration platform developed by Apache. NixOS is a Linux-based operating system that provides a declarative approach to configuration management.
In this tutorial, we will guide you through the steps to install Superset on the latest version of NixOS.
Prerequisites
Before we start, make sure you have the following prerequisites:
- A running instance of NixOS latest
- A user account with sudo privileges
- You have access to the command line interface
Step 1: Install Dependencies
To begin, we will install the dependencies required for building and installing Superset.
Open up a terminal on your NixOS instance and run the following command:
sudo nix-env -iA nixos.python36Packages.{pip,libxml2,libxml2-dev,libxslt,libxslt-dev}
This will install pip and the necessary development libraries for libxml2 and libxslt.
Step 2: Create a Python Virtual Environment
The next step is to create a Python virtual environment for running Superset on NixOS.
Run the following commands to set up a virtual environment:
sudo mkdir /opt/superset
sudo chown $USER /opt/superset
cd /opt/superset
python3 -m venv venv
source venv/bin/activate
After running the above commands, you will be inside the virtual environment.
Step 3: Install Superset
With the virtual environment set up, we can now install Superset using pip.
Run the following command to install Superset:
pip install apache-superset
This will install the latest version of Superset with all its dependencies.
Step 4: Set Up the Database
Superset requires a database to store its configuration and metadata. We will use PostgreSQL for this purpose.
To set up PostgreSQL, run the following commands:
sudo nix-env -iA nixos.postgresql11
sudo systemctl start postgresql
sudo systemctl enable postgresql
sudo -u postgres createuser -s $USER
This will install PostgreSQL 11 and create a user with superuser privileges.
With PostgreSQL set up, we now need to create a database and initialize it with Superset's schema.
Run the following command to create the database:
createdb superset
This will create a new database called superset.
Next, we need to initialize Superset's metadata tables in the database. Run the following command to do so:
superset db upgrade
This will create the necessary tables in the superset database.
Step 5: Start the Superset Server
With Superset installed and the database set up, we can now start the Superset server.
Run the following command to start the Superset web server:
superset run -h 0.0.0.0 -p 8088 --with-threads --reload --debugger
This will start the Superset server on IP address 0.0.0.0 with port 8088. You can access the Superset web interface at http://<server-ip>:8088.
Conclusion
Congratulations! You have successfully installed Superset on the latest version of NixOS.
With Superset installed, you can now use it to create interactive data visualizations and dashboards. Happy data exploration!
