A PPA (or Personal Package Archive) is a software repository provided by members of the Ubuntu Linux community. Software contained in a PPA can be downloaded and installed via apt, Ubuntu’s default package management system.

Adding a user and granting that user root privileges is one of the many tasks of a system admin.  Once a user has been added and granted root privileges they’ll be able to login to your Ubuntu VPS and perform vital functions for the upkeep of the system.

What Is Virtualenv?

Virtualenv is a tool that creates an isolated environment separate from other projects. In this instance, we will be installing different Python versions, including their dependencies.  Creating a virtual environment allows us to work on a Python project without affecting other projects that also use Python. It will utilize Python's core files on the global environment to run, thus saving you disk space while providing the freedom to use different Python versions for separate apps or projects.

What is an Apache Error?

An Apache error is a message generated by the Apache Web Server software and is usually a result of a coding issue or server misconfiguration. Apache errors may include Internal Server Error or 403 Forbidden messages. They can range from minor, easily fixed errors to more serious ones that may require support from a system administrator. Therefore, understanding the causes of Apache errors helps take the necessary steps to resolve the issue.

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.

Arguably one of the easiest tools to use for installing and managing Python packages, Pip has earned its notoriety by the number of applications utilizing this tool.

If you are looking to collaborate with your coworkers or employees and create and share documents on your Ubuntu VPS server without taking up space on your local computer system, LibreOffice is the perfect tool for you.

This powerful tool is currently in use by millions around the world as a free and open-source alternative to the Microsoft Office Suite of tools.

PostgreSQL supports many client authentication methods, but in this case we’re only going to concern ourselves with two: password and md5.

PostgreSQL (pronounced post-gress-Q-L) is a household name for open source relational database management systems.

It is object-relational, meaning that you’ll be able to use objects, classes in database schemas, and the query language.  In this tutorial, we will be demonstrating some essentials like how to create, list, and delete a Postgres database.
