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