Redash is an open-source software for creating data visuals, tables and charts. In this tutorial, we will walk you through how to install Redash on Clear Linux Latest.
To install Redash, you should have:
Firstly, you need to make sure your Clear Linux system is up-to-date with the latest software packages. To do so, run the command below.
sudo swupd update
You may be required to restart the system if certain kernel-related packages were updated. In that case, run the command below to restart the system.
sudo reboot now
Before installing Redash, we need to install the required software packages. The following command installs the required packages.
sudo swupd bundle-add python3-basic python3-cryptography python3-wheel python3-dev python3-icu python3-virtualenv nodejs-basic
After running the command, wait for the process to complete successfully.
Redash uses PostgreSQL as its backend database system. To install PostgreSQL on Clear Linux, run the following command.
sudo swupd bundle-add postgresql-12
After installing PostgreSQL, you'll need to create a database for Redash. To do so, run the following command:
sudo -iu postgres createdb redash
The above command creates a new database named redash. Now, you'll also need to create a new PostgreSQL user account and grant access to the redash database. Run the following command as the postgres user.
sudo -iu postgres
psql
CREATE USER redash WITH PASSWORD 'password';
GRANT ALL PRIVILEGES ON DATABASE redash TO redash;
Now, we'll create a new user to run Redash as a system service. This user account will be used to store and run the Redash system files.
To do so, run the following command.
sudo useradd -r -s /bin/false redash
Finally, we'll install Redash using virtualenv and npm.
mkdir ~/redash
cd ~/redash
git clone https://github.com/getredash/redash.git
cd redash
sudo apt-get install python3-venv
python3 -m venv ./
source bin/activate
pip3 install --upgrade pip
pip3 install wheel
pip3 install -r requirements.txt
npm install
npm run build
Next, create a new environment file using the contents of the sample file provided.
cp .env.sample .env
Next, set the environment variables in the .env file.
export REDASH_SECRET_KEY=$(openssl rand -hex 32)
export REDASH_DATABASE_URL="postgresql://redash:password@localhost/redash"
export REDASH_REDIS_URL="redis://localhost:6379/0"
export REDASH_LOG_LEVEL="INFO"
export REDASH_MAIL_DEFAULT_SENDER="support@myawesomecompany.com"
export REDASH_MAIL_SERVER="smtp.gmail.com"
export REDASH_MAIL_PORT=587
export REDASH_MAIL_USE_TLS=True
export REDASH_MAIL_USERNAME="support@myawesomecompany.com"
export REDASH_MAIL_PASSWORD=<your-gmail-app-password>
Note: Replace the password, myawesomecompany.com, and <your-gmail-app-password> placeholders with your own values.
/bin/sh -c "./bin/run ./manage.py database create_tables"
After the process is complete, deactivate the virtualenv using the command deactivate.
We will start the Redash process using PM2, a process manager for Node.js applications.
Start by installing PM2:
npm install -g pm2
Then, start Redash with the following command:
sudo env "PATH=$PATH" pm2 start --name "redash" /home/<USER_NAME>/redash/redash/index.js
Note: Replace <USER_NAME> with your own user name.
Finally, check the status of the Redash process using:
sudo env "PATH=$PATH" pm2 status
You should see the Redash process listed as online.
At this point, you should have successfully installed and configured Redash on Clear Linux. You can now use Redash to create visualizations and data tables for your data.
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!
