In this tutorial, we will guide you through the installation process of Lewsnetter on an Ubuntu Server. Lewsnetter is an open-source tool that allows you to collect and analyze logs from various sources, such as Linux servers, Windows servers, network devices, and more.
Before you start with the installation process, make sure that you have the following prerequisites installed on your Ubuntu Server:
Lewsnetter requires MongoDB to store its data. To install MongoDB, run the following command:
sudo apt update
sudo apt install -y mongodb
After the installation process, start the MongoDB service and enable it to start at system boot.
sudo systemctl start mongodb
sudo systemctl enable mongodb
Lewsnetter is written in Python. Therefore, Python 3 and Pip package manager are required to install Lewsnetter. Run the following command to install Python 3 and Pip:
sudo apt update
sudo apt install -y python3 python3-pip
Lewsnetter is hosted on Github, and we need Git to clone the Lewsnetter repository. Run the following command to install Git:
sudo apt update
sudo apt install -y git
Next, clone the Lewsnetter repository using the Git command:
git clone https://github.com/bborn/lewsnetter.git
After the cloning process, navigate to the Lewsnetter directory using the following command:
cd lewsnetter
A Python virtual environment is recommended to avoid conflicts between different Python packages. Run the following command to create a virtual environment:
python3 -m venv venv
Activate the virtual environment using the following command:
source venv/bin/activate
To install the Lewsnetter dependencies, navigate to the Lewsnetter directory and run the following command:
pip install -r requirements.txt
Before running Lewsnetter, we need to configure the database connection and other settings such as log sources, email alerts, and more.
Navigate to the Lewsnetter directory and create a configuration file using the following command:
cp config.default.py config.py
Then, open the config.py file using your preferred text editor:
nano config.py
Update the following settings:
Save and close the file.
Finally, we can run Lewsnetter.
Activate the virtual environment using the following command:
source venv/bin/activate
Then, run the following command to start Lewsnetter:
python lewsnetter.py run
Lewsnetter will start collecting and analyzing logs from the configured sources.
Congratulations! You have successfully installed and configured Lewsnetter on your Ubuntu Server. You can now monitor your system logs and receive email alerts for critical events.
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!
