Installing Redash on Debian Latest

In this tutorial, we will be installing Redash, an open-source platform that allows you to connect and query multiple data sources to visualize and share data insights.

Prerequisites

A Debian Latest system.
sudo (superuser) privileges.

Step 1: Install dependencies

Before we can install Redash, we need to install its dependencies. The following command will install the necessary dependencies:

sudo apt-get update
sudo apt-get install build-essential pwgen libffi-dev libssl-dev libpq-dev python3-dev python3-pip

Step 2: Create a Redash user

It is highly recommended to create a dedicated user for running Redash. You can create a new user with the following command:

sudo adduser --system --shell /bin/bash --group redash

Step 3: Install and configure PostgreSQL

Redash uses PostgreSQL as its database backend. You can install PostgreSQL by running the following command:

sudo apt-get install postgresql

Once PostgreSQL is installed, you can create a new user and database for Redash:

sudo -u postgres createuser redash
sudo -u postgres createdb redash -O redash

You also need to configure PostgreSQL to allow remote connections by editing the pg_hba.conf file:

sudo nano /etc/postgresql/{version}/main/pg_hba.conf

and add the following line at the end of the file:

host	all	all	0.0.0.0/0	md5

Then, restart PostgreSQL:

sudo service postgresql restart

Step 4: Install Redash

The easiest way to install Redash is to install it using pip. You can install Redash by running the following commands:

sudo pip3 install redash[all]

Step 5: Configure Redash

You can configure Redash by editing the configuration file at /opt/redash/env. First, copy the sample configuration:

sudo cp /opt/redash/.env.sample /opt/redash/env

Next, edit the configuration file using your preferred text editor:

sudo nano /opt/redash/env

You need to set the following variables in the configuration file:

REDASH_SECRET_KEY=<your-secret-key>
REDASH_DATABASE_URL=postgresql://redash@localhost/redash
REDASH_COOKIE_SECRET=<your-cookie-secret>
REDASH_WEB_WORKERS=4
REDASH_ADDITIONAL_QUERY_RUNNERS=redash.query_runner.postgres_pg8000

Replace <your-secret-key> and <your-cookie-secret> with your own secret keys.

Step 6: Start Redash

You can start Redash by running the following command:

sudo /opt/redash/bin/run

By default, Redash listens on port 5000. You can access the Redash web interface by navigating to http://localhost:5000 in your web browser.

Congratulations, you have successfully installed Redash on Debian Latest!
