How to Install Redash on Arch Linux

Redash is a data visualization and dashboarding tool that allows users to connect, query, and visualize data from a variety of different sources. In this tutorial, we will guide you through the process of installing Redash on an Arch Linux server.

Prerequisites

Before you start, make sure your Arch Linux server is up-to-date using the following command:

sudo pacman -Syu

You will also need to install these dependencies:

• Python 3.6+ (including pip)
• PostgreSQL
• Redis

Step 1: Create a Virtual Environment and Install Dependencies

It is recommended to install and run Redash within a Python virtual environment. To set up a virtual environment, follow the steps below:

1. Install virtualenv:

   sudo pip install virtualenv
   

2. Create a new virtual environment for Redash:

   virtualenv redashenv
   

3. Activate the virtual environment:

   source redashenv/bin/activate
   

Once you have activated the virtual environment, install the required dependencies using pip.

sudo pip install setuptools==49.6.0
sudo pip install wheel==0.34.2
sudo pip install -r https://raw.githubusercontent.com/getredash/redash/master/requirements.txt
sudo pip install redash==9.0.0.b50339

Step 2: Create a PostgreSQL Database

Next, we need to create a PostgreSQL database for Redash. Follow these steps:

1. Log in to PostgreSQL as a superuser:

   sudo su - postgres
   psql
   

2. Create a new user and database:

   CREATE USER redash WITH PASSWORD 'password';
   CREATE DATABASE redash OWNER redash;
   

3. Grant all privileges to the new user:

   GRANT ALL PRIVILEGES ON DATABASE redash TO redash;
   

4. Exit PostgreSQL:

   \q
   exit
   

Step 3: Configure Redash

Now that we have the required dependencies and PostgreSQL database, we need to configure Redash.

1. Create a configuration file:

   cp /opt/redash/redash.settings.py.example /opt/redash/redash.settings.py
   

2. Modify the following settings in the redash.settings.py file:

   DATABASE_URL = 'postgresql://redash:password@localhost/redash'
   REDASH_REDIS_URL = 'redis://localhost:6379/0'
   

   You can also modify other settings in this file to customize Redash. Refer to the official documentation for more information.

Step 4: Initialize the Database

Now we need to initialize the database schema and add a default admin user.

sudo REDASH_DATABASE_URL=postgresql://redash:password@localhost/redash redash-manager database create_tables
sudo REDASH_DATABASE_URL=postgresql://redash:password@localhost/redash redash-manager users create --admin --password admin "Admin" "admin@domain.com"

Step 5: Run Redash

Finally, start the application:

sudo REDASH_DATABASE_URL=postgresql://redash:password@localhost/redash REDASH_REDIS_URL=redis://localhost:6379/0 REDASH_MAIL_SERVER=smtp.gmail.com REDASH_MAIL_USE_TLS=true REDASH_MAIL_PORT=587 REDASH_MAIL_USERNAME=email@example.com REDASH_MAIL_PASSWORD=password redash run --debug

If everything is working correctly, you should see the following output:

Dashboards on http://0.0.0.0:5000/dashboard/list
Queries on http://0.0.0.0:5000/queries/
E-mails on http://0.0.0.0:5000/alerts/

Conclusion

In this tutorial, you learned how to install Redash on Arch Linux. Now you can connect, query, and visualize your data all in one place!

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
