In this how to check hard drive power on hours in Linux you will see how you might prevent disaster, by knowing details about system’s storage device in terms of “power on” hours (runtime), number of read and writes, or bad blocks, to determine the overall hard drive’s health and ageing.
In this tutorial we will talk about how to migrate Apache to Nginx. Apache and Nginx are probably the most used Web servers on Linux. The former is the most ancient of the two: its development started in 1995, and it played a very important role in the World Wide Web expansion; it is still the most popular web server around.
The ext2, ext3 and ext4 filesystems are some of the most known and used filesystems specifically designed for Linux. The first one, ext2 (second extended filesystems) is, as its name suggests, the older of the three. It has no journal feature, which is the biggest advantage of its successor over him: ext3. Released in 2008, ext4 is the more recent, and currently the default filesystem on many Linux distributions.
This SQLite Linux tutorial is intended for beginners who wish to learn how to get started with SQLite database. SQLite is one of the world’s most widely-used Database programs. So, what is a Database, and what is SQLite?
SELinux, which stands for Security Enhanced Linux, is an extra layer of security control built for Linux systems. SELinux has three possible modes in which it can be running. Depending on which mode it’s in will determine the behavior of SELinux. In this tutorial, we’ll show you how to check the SELinux operational mode.
SELinux, which stands for Security Enhanced Linux, is an extra layer of security control built for Linux systems. The original version of SELinux was developed by the NSA. Other key contributors include Red Hat, which has enabled it by default in their own RHEL and its derivative Linux distributions.
In this tutorial you will learn how to increase disk size on VirtualBox. One of the great things about installing an operating system into a virtual machine is that we can easily change the machine’s CPU utilization limit, its memory usage, and the amount of hard drive space it has. With VirtualBox, all of these hardware specifications can even be changed long after the virtual machine is created.
The wipefs Linux command utility can be used to erase various types of signatures from a device (partition tables, filesystem signatures, etc…). It is available in the repository of all the most used Linux distributions, and it is usually installed by default as part of of the
util-linux package, which contains also other essentials utilities aimed at system maintenance, so we should never have to install it explicitly. In this tutorial we will see how to use wipefs to gather information about the existing signatures and how to erase them.
In Linux, many applications and system services will store log files. These log files give a Linux administrator insight into how their system is performing, and are invaluable when troubleshooting issues. However, log files can get unwieldy very quickly. For example, if your web server software logs every visit to your website, and you get thousands of viewers per day, there will be way too much information to feasibly squeeze into one text file.
