How to install Redash on Linux Mint Latest

Redash is an open-source platform for querying and visualizing data from various sources. In this tutorial, we will guide you through the steps to install Redash on Linux Mint latest.

Prerequisites

• A Linux Mint latest server (with sudo privileges)
• Nginx installed and running
• PostgreSQL database installed and running

Step 1: Install Required Packages

First, we need to update and upgrade the system packages by running the following command:

sudo apt-get update && sudo apt-get upgrade -y

Next, we need to install some required packages for Redash:

sudo apt-get install build-essential python-dev python-pip libpq-dev postgresql-client-12 redis-server -y

Step 2: Install Supervisor

Supervisor is a process control system that keeps Redash running in the background. We can install it with the following command:

sudo apt-get install supervisor -y

Step 3: Install Redash

Next, we will install Redash from its official Pypi repository. To do this, run the following command:

sudo pip install redash

Step 4: Create Database and User

We need to create a PostgreSQL database and user for Redash. To accomplish this, we can run the following commands:

sudo su postgres
psql

CREATE USER redash WITH PASSWORD '<your-password>';
CREATE DATABASE redash WITH OWNER redash ENCODING 'UTF8';
\q
exit

Please replace <your-password> with your desired password.

Step 5: Configure Redash

We need to configure Redash to connect to our PostgreSQL database. We can do this by creating a redash.cfg file in the following path /opt/redash with the following contents:

# /opt/redash/redash.cfg
REDIS_URL = "redis://localhost:6379/0"
DATABASE_URL = "postgresql://redash:<your-password>@localhost/redash"

Please replace <your-password> with the password that you set in Step 4.

Step 6: Configure Supervisor

We need to configure Supervisor so that Redash can start automatically on system startup. To do this, run the following command:

sudo nano /etc/supervisor/conf.d/redash.conf

Then, copy the following contents into the file:

[program:redash]
command=/usr/local/bin/gunicorn --workers 4 --bind 127.0.0.1:5000 redash.wsgi:app
directory=/opt/redash/current
user=redash
autostart=true
autorestart=true
stopasgroup=true
killasgroup=true

Save and close the file.

Step 7: Start and Enable Services

To start and enable the services, run the following commands:

sudo systemctl start supervisor
sudo systemctl enable supervisor
sudo systemctl start redis-server
sudo systemctl enable redis-server

Step 8: Configure Nginx

Finally, we need to configure Nginx as a reverse proxy to access Redash. To accomplish this, create an Nginx configuration file, as follows:

sudo nano /etc/nginx/sites-available/redash.conf

Then, paste the following contents into the file:

server {
    listen 80;
    server_name your-domain.com;
    access_log /var/log/nginx/redash.access.log;
    error_log /var/log/nginx/redash.error.log;

    location / {
        proxy_pass http://localhost:5000/;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

Please replace your-domain.com with your own domain name or IP address.

Save and close the file.

Then, activate the configuration by creating a symlink:

sudo ln -s /etc/nginx/sites-available/redash.conf /etc/nginx/sites-enabled/

Finally, restart Nginx to apply the changes:

sudo systemctl restart nginx

Conclusion

Congratulations! You have successfully installed Redash on Linux Mint latest. You can now access Redash by visiting your server's IP address or domain name on a web browser.
