NGINX is a web server that is becoming an increasingly popular option for web hosting, as sixteen percent of all sites on the internet are utilizing NGINX. This percentage is constantly increasing as clients require a web server that can serve content faster. It can also be used for proxies, reverse proxies, load balancing, and more depending on what modules you load onto NGINX. One of the significant differences between Apache (a popular webserver) and NGINX is the way each system handles access rules. If you are familiar with using .htaccess rules in Apache, then the method that NGINX uses of including directives in the server's vhost block will be a substantial change.

One of the nice things about cPanel-based servers is the way that they keep the location of key files in the same place across all the various cPanel versions.  Due to this consistency one always knows where to look for logs files for all services running on a cPanel server.

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.

The most common way to remotely manage a Windows server is through Remote Desktop Protocol. By default, Liquid Web’s Windows servers only allow the members of the administrators' group remote desktop access. However, the Remote Desktop Users group grants its members access to securely connect to the server through RDP (Remote Desktop Protocol) as well.

What is Apache Spark?

Apache Spark is a distributed open-source, general-purpose framework for clustered computing. It is designed with computational speed in mind, from machine learning to stream processing to complex SQL queries. It can easily process and distribute work on large datasets across multiple computers.

Preflight Check

• These instructions are intended specifically for solving the error: 500 OOPS: priv_sock_get_int.
• We will be working from a Liquid Web Self Managed Fedora server, while logged in as the root user.

The Fix

This error may occur when attempting to connect to a vsftpd FTP server. You simply need to add one line to the configuration file, which this article assumes is in the default location of /etc/vsftpd/vsftpd.conf.

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.
