How to Install Patrowl on Elementary OS Latest

Introduction

Patrowl is an open-source web application that provides a security automation framework. It allows users to monitor, analyze, and respond to various security threats. In this tutorial, we will explain how to install Patrowl on Elementary OS Latest.

Prerequisites

Before installing Patrowl on your Elementary OS Latest system, you will need:

• A user account with sudo privileges.
• Access to a terminal window.
• Internet connectivity to download the required software packages.

Step 1: Install required dependencies

In order to install Patrowl, we need to ensure that all the required dependencies are installed. To do this, we can use the following command:

sudo apt-get install -y python python-pip python-dev python-virtualenv python-libxml2 python-libxslt1 python-gmpy2 git build-essential

This command will install all the necessary packages that Patrowl requires to run on Elementary OS Latest.

Step 2: Install PostgreSQL

Patrowl requires PostgreSQL as its primary database. To install PostgreSQL, run the following command:

sudo apt-get install -y postgresql libpq-dev

After installation, we need to configure PostgreSQL to listen to all network interfaces so that we can connect to our database externally. To do this, open the PostgreSQL configuration file using your preferred text editor:

sudo nano /etc/postgresql/13/main/postgresql.conf

Next, locate the listen_addresses parameter and update it as follows:

listen_addresses = '*'

Save and close the file.

Lastly, we need to modify the pg_hba.conf file to accept external connections. Open the file with the following command:

sudo nano /etc/postgresql/13/main/pg_hba.conf

In the file, locate the following line:

host    all             all             127.0.0.1/32            md5

Under this line, add the following:

host    all             all             0.0.0.0/0               md5

Save and close the file.

Finally, restart the PostgreSQL service by running this command:

sudo systemctl restart postgresql

Step 3: Clone the Patrowl repository

We will now clone the Patrowl repository from Github using the following command:

git clone https://github.com/Patrowl/PatrowlManager.git

Change into the Patrowl directory:

cd PatrowlManager

Step 4: Create and activate a virtual environment

Next, we will create a virtual environment for Patrowl using the following command:

virtualenv -p python3 venv

Activate the virtual environment with:

source venv/bin/activate

Step 5: Install required Python modules

With the virtual environment active, we can now install the required Python modules for Patrowl as follows:

pip install -r requirements.txt

Step 6: Configure Patrowl

Patrowl comes with an example configuration file config.dist.py. To configure Patrowl, rename this file to config.py:

cp config.dist.py config.py

Then, open the config.py file using your preferred text editor:

nano config.py

Update the following lines in the file with your desired settings:

DATABASE_URI = 'postgresql://patrowl:patrowl@localhost/patrowl'
SECRET_KEY = 'CHANGE-ME'

Save and close the file.

Step 7: Initialize the database

Next, we will create the Patrowl database tables by running the following commands:

python manage.py db init
python manage.py db migrate
python manage.py db upgrade

Step 8: Run the Patrowl server

Finally, we will start the Patrowl server using the following command:

python run.py

Once the server is running, you can access the Patrowl web interface by visiting http://localhost:7784/ from your web browser.

Conclusion

In this tutorial, we have demonstrated how to install Patrowl on Elementary OS Latest. Patrowl is a powerful security automation framework that provides an effective way to monitor, analyze, and respond to various security threats.
