What is Puppet?
Puppet is a cross-platform client-server based application used for configuration management. It handles the software and its configurations on multiple servers. There are two versions available. One is open-source, the other is a commercial version. It works on both Linux and Windows platforms. It uses a declarative approach to automate updates, installations, and other tasks. This feature allows the software to configure those systems using files called manifests. A manifest contains the instructions for a group or type of server(s) being controlled.Continue reading “What is Puppet and What Role Does it Play in DevOps?”
What is a VPN?
A Virtual private network (VPNs) creates a secure connection between a remote computer and another network. The connection itself is encapsulated and encrypted which provides a protected communications channel between the two points.
A VPN is becoming more crucial in today’s security-related society. Due to increasing safety concerns, the proportional use of these services is growing exponentially. This technology targets several critical aspects of our online experience: mainly privacy and security.Continue reading “What is a Virtual Private Network and How Does it Work? “
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.
This error relates to logging into phpMyAdmin, an open source tool used for the administration of MySQL.Continue reading ““Password is Forbidden” PhpMyAdmin Login Error Solved”
MySQL via Command Line 101: Basic Database Interaction
In this article, we will be discussing how to use MySQL to create a new user on Linux via the command line. We will be working on a Liquid Web core-managed server running CentOS version 6.5 as the root user. The commands used should also work on later versions of MySQL on CentOS as well.
MySQL is a relational database management application primarily used on Linux and is a component of the LAMP stack (Linux, Apache, MySQL, and PHP).
- Log in as the root user.
- Have access to a terminal.
- Basic knowledge of the command line.
What is OpenJDK?
OpenJDk or Open Java Development Kit is a free, open-source framework of the Java Platform, Standard Edition (or Java SE). It contains the virtual machine, the Java Class Library, and the Java compiler. The difference between the Oracle OpenJDK and Oracle JDK is that OpenJDK is a source code reference point for the open-source model. Simultaneously, the Oracle JDK is a continuation or advanced model of the OpenJDK, which is not open source and requires a license to use.Continue reading “How to Install OpenJDK 11 on CentOS 8”

IPython is a robust Python shell that handles indentation, syntax highlighting, tab completion, and more. In this tutorial, we will cover how to install IPython and walk through how to make use of some features it makes available. Python provides a default REPL or shell for users to run Python code in real-time and see the results. While this default REPL is extremely useful, it does not handle things like indentation, syntax, or highlighting. This is where Ipython shines.Continue reading “How to Install and Use IPython”
What is Containerization?
Containerization is a form of virtualized operating system developed as a response to the many problems of hardware-level virtualization. Because the latter runs a full-blown guest operating system, it is very resource-intensive and incurs a significant amount of overhead, but containerization is much lighter. Since the containers share the host machine’s kernel, the resources are not wasted on running separate operating system tasks. This allows for a much quicker and lightweight deployment of applications.Continue reading “How to Install and Use Containerization”
