A Virtual Environment or a "venv" is a Python module that creates a unique environment for each task or project. It installs the packages we need that are unique to that setting while keeping your projects neatly organized. Additionally, venv never actually modifies the system’s default Python versions or modules that are installed on the system. Using venv essentially allows for a unique working environment while avoiding any disruptions to other variants of Python that are used, but not related to our project.

Once in a while, perhaps on a Development server, MySQL will not be set up with a root password. The aforementioned configuration is generally thought of as against best practices, however, if it is what you're dealing with, then it could also interfere with PhpMyAdmin.

What is Jupyter Notebook?

Jupyter Notebook is an extremely powerful open-source, web-based tool that facilitates the creation of documentation. There are many different avenues to provide technical documentation or demonstrations, but Jupyter Notebook makes it possible to embed visualizations and execute live code. It is useful to be able to utilize documentation to describe development concepts or planning, but providing working examples within documentation can be a more effective way of conveying information. This tutorial will cover how to install Jupyter Notebook on an Ubuntu 18.04 LTS server and connect to it remotely via an SSH tunnel.

What is Elasticsearch?

Elasticsearch is a distributed, full-text, open-source search engine. It provides multi-tenant capabilities in analyzing aggregate data types from sources like Logstash or Kibana.

If you are still using Ubuntu version 16.04, you may want to consider updating to the latest Long Term Support release, version 18.04. In this post, we will cover what a Long Term Support release is and why you would want to use it. You will also learn the significant changes between 16.04 and 18.04. Last, but not least, you will also learn how to upgrade your dedicated server from Ubuntu 16.04 to Ubuntu 18.04.

When updating from Ubuntu 16.04 to 18.04, we used the following command as one of the steps to update to the newer version. 

What is Logstash?

Logstash is a free, open source, server-side data collection and processing engine which uses dynamic pipelining capabilities. It takes in information from multiple data sources, reconstructs it, and then sends it to a destination of our choice. Logstash also cleans and modifies the data for use in an advanced outbound analytics and visualization use cases. It is the L in the ELK stack (Elasticsearch, Logstash and Kibana) and is typically responsible for sending data to Elasticsearch.
