Installing XAMPP on Ubuntu Linux

How to install XAMPP on Ubuntu Linux

by

Hosting a website on a Linux system usually involves multiple software packages that operate together to deliver a web browsing experience to potential viewers. For example, it’s common for PHP to dynamically render web content but retrieve data from a database. These are two separate components and they must both be installed to present a website as intended.

XAMPP is a software stack that can run on Ubuntu Linux and make your life a little easier when it comes to web hosting. XAMPP stands for cross-platform (X), Apache (A), MariaDB (M), PHP (P), and Perl (P). These are all common components used in web hosting, and combining them into a single installation makes the initial setup less complicated. XAMPP also comes with Bitnami, which allows you to install content managements systems, such as WordPress, as well as other apps on top of your XAMPP installation if you choose.

In this guide, we’ll cover the installation of XAMPP on Ubuntu Linux. Follow along with our step by step instructions to get it setup on your own system.

Grub rescue on a Linux system

Introduction to Grub Rescue

by

Grub is a boot loader for many Linux distributions which basically tells your system where it can find installed operating system(s) on one or more hard drives. Your PC needs this information in order to boot into your Linux distro successfully.

When powering on your PC, Grub begins to look for installed operating systems. If it has trouble finding one or if it can’t load part of its config, you’ll be brought to the Grub Rescue command line interface that allows you to repair the boot loader.

In this guide, we’ll show how Grub Rescue works, along with the commands you’ll need in order to repair a broken boot loader and get back into your Linux install.

NOTE
If you experience a no such partition error, we have a separate guide for how to fix grub error: no such partition grub rescue

In this tutorial you will learn:

  • What are the Grub files?
  • How to repair Grub
  • What to do if Grub is completely broken

Clearing memory cache and using free command to show before and after result

Clear cache on Linux

by

When files and system utilities are used by a Linux system, they’re temporarily stored in random access memory (RAM), which makes them much quicker to access. This is a good thing, since frequently accessed information can be quickly recalled, which ultimately makes your system perform faster.

The operating system determines how long to keep files cached in memory, but Linux also gives the user the ability to clear the cache manually. You normally will never need to do this, although there are edge situations where it can come in handy.

In this guide, we’ll show you how to clear the memory cache on Linux by clearing PageCache, dentries, and inodes from the command line.

In this tutorial you will learn:

  • What is PageCache, dentry, and inode cache?
  • How to clear cache
