Apache Cassandra is a NoSQL database intended for storing large amounts of data in a decentralized, high availability server cluster. NoSQL refers to a database with a data model other than the tabular relations used in relational databases such as MySQL, PostgreSQL, and Microsoft SQL.

Memcached is a distributed, high-performance, in-memory caching system that is primarily used to speed up sites that make heavy use of databases. It can however be used to store objects of any kind. Nearly every popular CMS has a plugin or module to take advantage of memcached, and many programming languages have a memcached library, including PHP, Perl, Ruby, and Python. Memcached runs in-memory and is thus quite speedy, since it does not need to write to disk. Here’s how to install it on CentOS 6:

In a vast majority of cases, Linux does a fantastic job of automatically scheduling processes. The more urgent processes are given a higher priority, and the less urgent processes a lower priority. In rare circumstances, the scheduler might not prioritize processes as you would like. For example, backup processes could be taking up resources that you would rather be used serving web pages. If you would like to regain a bit control over process priorities, the nice and renice commands will give you some.

Linux has a robust permissions system. This is a very good thing, as it enables a clear separation of roles among users, especially between the root user and your average user. Sometimes, though, you might want your average user to have some or all of root's privileges. In Linux, this is accomplished with sudo.

One of the common questions new users have when they get a fully managed dedicated server is “How do I log in to my control panel?” This article will show you how to login to your Plesk control panel. cPanel’s users should check out the article on logging into cPanel.

Softaculous is an easy to use one-click installer, allowing you to install software packages on your Fully Managed Linux server quickly, easily backup, and update any software that is installed with softaculous. While Softaculous is designed with ease of use in mind, it can be confusing to install software with Softaculous. The purpose of this article is to walk through installing a piece of software using Softaculous.

In this tutorial, we will be reviewing how to restore a domain from cPanel backups. While it is a good and useful thing to have entire server backups enabled, sometimes we only need to restore a single domain. In these situations, cPanel backups make it easy for us to restore a single site from the Web Host Manager (WHM) interface, or from the command line.

Due to the nature of the Internet, services for one domain do not need to be on one server. The website and email for a domain do not need to be on the same physical server. DNS is used to direct the traffic to the correct place, but DNS alone will not get all the bits to where they are supposed to be. Exim, cPanel’s SMTP service needs a little help beyond DNS to know how to handle mail that is generated locally. This is where /etc/localdomains and /etc/remotedomains come into play.

While editing files on a machine running some form of Windows and uploading them to a Linux server is convenient, it can cause unforeseen complications. Windows-based text editors put special characters at the end of lines to denote a line return or newline. Normally harmless, some applications on a Linux server cannot understand these characters and can cause the service to not respond correctly. There is a simple way to correct this problem: dos2unix.
