What is Webmin?

Webmin is a browser-based graphical interface to help you administrate your Linux server.  Much like cPanel or Plesk, Webmin allows you to set up and manage accounts, Apache, DNS zones, users and configurations.  As these configurations can get somewhat complicated Webmin works to simplify this process. The result is fewer issues during server and domain setup.  Which results in a stable server and a pleasant administration experience. Unlike Plesk or cPanel, Webmin is completely free and open to the public. Unfortunately, here at Liquid Web, we do not offer managed support for Webmin, but we are always willing to assist as much as possible when issues arise.   You can download Webmin from their site. Also, you can find some excellent documentation on this interface.

Configuring Multi-User FTP with User Isolation

This article is intended to give an overview of a chroot environment and configuring your FTP service for user isolation. This is done with a few lines within the main configuration file of the FTP service.

When investigating site infections or defacing on a Windows VPS Server, the most common root cause is poor file security or poor configuration choices when it comes to how IIS should access file content.  The easiest way to prevent this is to start with a secure site.

Mod_security, also commonly called Modsec for short, is a powerful WAF (Web Application Firewall) that integrates directly into Apache’s module system. This direct integration allows the security module to intercept traffic at the earliest stages of a request. Early detection is crucial for blocking malicious requests before they are passed along to web applications hosted by Apache websites. This provides and extra layer of protection against common threats a server faces. This article will explore the installation of mod_security along with the CRS (Core Rule Set) in an Ubuntu 16.04 LTS Server running Apache 2.4.

What is FTP?

You or your developer may want to have access via FTP (File Transfer Protocol) to the folders for the project or domain that is being worked on. FTP is a quick and easy way for someone to connect to their project, without having to have full access to RDP into the server. An FTP user will only have access to the folders that are designated to them, limiting them in their own environment so as not to accidentally change other user’s files and file structure on their project/domain. In this tutorial, we will cover how to utilize FTP on a Core/Self-Managed Dedicated server or a VPS server, as well as a Plesk Server.  Let’s jump right in!

What is Redis? 

Redis or “REmote DIctionary Server” is defined as an open source, “key-value” database storage medium, which is additionally known as a data structure server. At its heart, Redis works with key-value pairs and stores data in a location that’s easily referenceable by two specific values. These key-value associations are usually a set of two linked data entries which are made up by a key, which is a unique identifier for a type of data and, the value, which can be either the particular data that is identified or, an indicator to the location of that data.

What is the purpose of Git?

Git gives you a way to not only track changes in source code, but it can also be used to track changes in files.  It then stores the data in what is called a repository, also known as a repo. In short, Git is a tool used as a version control system (VCS), allowing you to distribute changes from your local machine to the repo and vice versa.  In this tutorial, we’ll be instructing on how to install and configure git onto an Ubuntu 18.04 server.

This article outlines the procedure for replacing the native MySQL®️ or MariaDB®️ service that is preinstalled on any typical Plesk Onyx 11 CentOS 7 server. The procedure outlines removal of the existing MySQL related binaries and replaces them with an adequate version of the Percona binaries. Once these Percona binaries are in place, a typical multistage MySQL Incremental version upgrade is processed to bring the existing databases and Percona binaries to the desired Percona 5.7 version.
