How to Install Redash on NetBSD

Redash is an open-source tool that helps data analysts and scientists to query, visualize, and share data sources. In this tutorial, we will guide you through the installation process of Redash on NetBSD.

Prerequisites

Before proceeding with the installation, you need to make sure that your system meets the following requirements:

• NetBSD 7.1 or later installed
• Python 2.7 or later installed
• PostgreSQL 9.5 or later installed
• Node.js 8.x or later installed

Step 1 - Setup a PostgreSQL Database

Create a database and a user for Redash. You can do this by running the following command in your terminal:

$ sudo -u postgres psql
postgres=# CREATE DATABASE redash;
postgres=# CREATE USER redash WITH PASSWORD 'mysecretpass';
postgres=# GRANT ALL PRIVILEGES ON DATABASE redash TO redash;
postgres=# \q

Step 2 - Install and Configure Redis

Redash requires Redis to store its internal data. You can install Redis on NetBSD by running the following command:

$ sudo pkg_add redis

After installing Redis, you need to configure it to allow remote connections by editing the configuration file at /usr/pkg/etc/redis.conf. Uncomment the following line:

# bind 127.0.0.1

to:

bind 0.0.0.0

Save and close the file.

Start Redis by running:

$ sudo /etc/rc.d/redis start

Step 3 - Install Redash

Clone the Redash repository from GitHub using the following command:

$ git clone https://github.com/getredash/redash.git

Now, navigate to the cloned repository using:

$ cd redash

Install the required Python libraries by running:

$ sudo python setup.py install

Run the following command to install front-end dependencies:

$ cd client && npm install

After the installation, build the JavaScript and CSS files by running the following command:

$ npm run build

Step 4 - Configure Redash

Create a configuration file for Redash by copying the template:

$ cp .env.example .env

Open the .env file and update the following settings according to your system configuration:

# Your Redash instance name (e.g. My Redash Instance)
REDASH_NAME=My Redash Instance

# PostgreSQL database URL (e.g. postgresql://user:pass@localhost/dbname)
REDASH_DATABASE_URL=postgresql://redash:mysecretpass@localhost/redash

# Redis URL (e.g. redis://localhost:6379/0)
REDASH_REDIS_URL=redis://localhost:6379/0

# Use Celery for async jobs
REDASH_CELERY_BROKER=redis://localhost:6379/0

Save and close the file.

Step 5 - Start Redash

Start Redash by running the following command:

$ python manage.py runserver

You should see the following output if everything goes well:

 * Running on http://0.0.0.0:5000/ (Press CTRL+C to quit)

Now, open your web browser and visit http://localhost:5000 to access your Redash instance.
