We’ll show you how to set up SSH keys on Ubuntu 16.04. SSH or Secure SHELL is the most popular and trusted UNIX-based cryptographic network protocol. It can be used for a secure data communication, remote server logins, remote command execution, and many other secure network services between two networked servers. Normally, password authentication is used to connect to a remote server via SSH but in this tutorial we will show you how to login to your Ubuntu 16.04 VPS using SSH keys. We will generate a key pair (private and public key), place the private key on your server and then use your locally stored private key to gain access to your server. This method provides a more secure way of connecting to your server, instead of just using a password.
In this tutorial, we will show you, how to use the Ubuntu crontab. In a few simple steps, we will explain, how to automate your system tasks on Ubuntu, using the crontab in Ubuntu. The cron software utility is a time-based job scheduler in Unix-like operating systems. Cron is driven by a crontab (cron table) file, a configuration file that specifies shell commands to run periodically on a given schedule. The crontab files are stored where the lists of jobs and other instructions to the cron daemon are kept. Users can have their own individual crontab files and often there is a system-wide crontab file (usually in /etc or a subdirectory of /etc) that only system administrators can edit.
In this post we will explain how to install Joomla on Ubuntu 16.04, with MariaDB 10.2, PHP-FPM 7.1 and Nginx. Joomla is an open-source content management system (CMS) for publishing web content written in PHP. Joomla is one of the most popular CMSs and it is used all over the world to power millions of websites of all shapes and sizes. This guide should work on other Linux VPS systems as well but was tested and written for an 
In today’s tutorial, we will show you how to change the root password in Linux. The root account on a Linux machine is the highest authority account on the system. It has control over everything, can delete and modify anything, and has permission to run any program. Simply put, the root account can do anything that the system supports. Typically, casual users never need to use the root account, while more experienced users need the root account more often, especially if they spend a large amount of their time at a terminal. So, even if you don’t use the root account much, it helps to put a more secure password so that malicious users don’t log into the root account and wreak havoc on your system.
