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.
To put it simply the goal of this repo was to provide greater ease of access to software on Enterprise Linux compatible distributions.
What’s an ‘EPEL repository’?
The EPEL repository is managed by the EPEL group, which is a Special Interest Group within the Fedora Project. The ‘EPEL’ part is an abbreviation that stands for Extra Packages for Enterprise Linux. The EPEL group creates, maintains and manages a high-quality set of additional packages. These packages may be software not included in the core repository, or sometimes updates which haven’t been provided yet. Continue reading “How to Enable an EPEL repository”→
cPanel is a server control panel which allows users the ability to access and automate both VPS server 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.

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.
One of the best tools for quickly finding files by filename is the locate command. The locate command reads one or more databases prepared by updatedb and writes file names matching at least one of the patterns to standard output, one per line.
These instructions are intended specifically for installing mlocate on CentOS 6.
I’ll be working from a Liquid Web Self Managed CentOS 6 server, and I’ll be logged in as root.
