While many know daemons from Greek mythology, we will learn what a daemon is in the world of software. If you ever manually installed software or a service on your server, a daemon runs in the background. This article will discuss what daemons are, the difference between a daemon and a process, the most common daemons, and how to use daemons on CentOS 6 and CentOS 7.

CentOS Options

With the recent announcement by CentOS 8 regarding the switch from CentOS 8 to CentOS Stream, this commonly used Linux distribution is being relegated to a mid-stage development version of RHEL. In essence, CentOS 8 becomes an early rolling-release distro for RHEL. As CentOS moves from being a follow-up distribution to the stable version of RedHat, to be, in effect, a prerelease version of RHEL, many users are looking for alternatives to replace their current operating systems with a long-term stable platform apart from RHEL and IBM who owns RedHat. 

Introduction

SNMP, or Simple Network Management Protocol, is widely used to communicate with and monitor network devices, servers, and more, all via IP. In the previous article, we installed an SNMP agent on a CentOS 6.5 server. This agent allows for the collection of data from our server and makes the information available to a remote SNMP manager. To add a little security, we'll now change the port that SNMP listens on.

The EPEL repository is an additional package repository that provides easy access to install packages for commonly used software. This repo was created because Fedora contributors wanted to use Fedora packages they maintain on RHEL and other compatible distributions.

Introduction

SNMP, or Simple Network Management Protocol, is widely used to communicate with and monitor network devices, dedicated servers, and more, all via IP. In this case, we'll be installing an SNMP agent on a CentOS VPS server, which will allow for collection of data from our server, and make the information available to a remote SNMP manager.

What is cPanel? 

cPanel is a server control panel which allows users the ability to access and automate our Cloud Dedicated, VPS, and  Dedicated server tasks and, provides the tools needed to manage the overall server, their applications, and websites.  Some features include the capability to modify php versions, creating individual cPanel accounts, adding FTP users, installing SSL’s, configuring security settings, and installing packages to name a few. cPanel and WHM have a vast range of customizations and configurations that can be completed to further personalize your platform specifically for your needs.  It also includes 24/7 support from cPanel as well.

Introduction

The servers that run our applications, our businesses, all depend on the stability and underlying features offered by the operating system (or OS) installed. As administrators, we have to plan ahead and think to the future of how our users will use the machines we oversee while simultaneously ensuring that those machines remain stable and online. There are numerous operating systems to choose from; however one of the most popular, most stable, and highly supported OSes is CentOS. A combination of excellent features, rock-solid performance stability, and the backing of enterprise-focused institutions such as Red Hat and Fedora have led to CentOS becoming a mainstay OS that administrators can count on.

Our previous article in this series focused on defining and fitting MPM to match your environment.  Building from our last tutorial we will be discussing specific details on how to adjust the previously mentioned Apache configuration directives on the various types of Liquid Web VPS servers as well as Core managed servers.  

• These instructions are intended specifically for removing a user on CentOS 6.
• I’ll be working from a Liquid Web Core Managed CentOS 6 server, and I’ll be logged in as root.
