Have spotlight search in KDE

The first few sentences are just my personal experience, so you can skip it and move on to the next part (Starting the configurations).

Some small complains about Ubuntu 14.04 LTS !

I Started using KDE for my Ubuntu system (since Unity was causing lot’s of system crash and reboots). Everything about KDE is OK and smooth, with 32GB RAM and Intel core i7 vPro 3.4GHz 8MB, and I’m having lots of fun working around and it increases my productivity, but I also missed the spotlight search of my MacBook. also KDE does not have good shortcuts for their plasma system and for example you can not use a windows key on your keyboard to open the application launcher! so I tried to find an easy way not to use mouse for opening my application. So here is a way to have spotlight search in KDE:

Start the configuration

Before everything I should say that I’m not going to install any application or write some weird shell, I’m going to sue the KDE settings in few clicks.
So let’s get to business:

Install and enable SSH in Ubuntu 14.04

I was setting up a service on a local computer with Ubuntu 14.04 Trusty Tahr OS which I realized there is no SSH server daemon what so ever on Ubuntu, so I thought installation and enabling SSH in Ubuntu 14.04 can be a issue for some beginners, so here is the solution:

sudo apt-get install openssh-server

Install PHP 5.3 on CentOS/RHEL

In this tutorial, like other tutorials, I assume that you have the root access to the server. I also assume that you have already installed Apache on your OS. (See installing Apache instructions here)

Notice: If you don’t have former PHP version on your server, just skip this first step and move on to the next step named “Preparing to Install PHP 5.3“.

Brief Introduction About Apache

To describe Apache HTTP Server, I prefare to use exact phrases from it’s Wikipedia page:

The Apache HTTP Server, commonly referred to as Apache (/əˈpætʃiː/), is web server software notable for playing a key role in the initial growth of the World Wide Web.
Apache was the first viable alternative to the Netscape Communications Corporation web server (currently named Oracle iPlanet Web Server)
As of March 2012 Apache was estimated to serve 57.46% of all active websites and 65.24% of the top servers across all domains.
Apache supports a variety of features, many implemented as compiled modules which extend the core functionality.
Some common language interfaces support Perl, Python, Tcl, and PHP.
Although the main design goal of Apache is not to be the “fastest” web server, Apache does have performance similar to other “high-performance” web servers.

So it would be a good choice to use Apache for your server.

Setup RHEL 5 or CentOS 5 Linux in Graphical Mode

CentOS is one of the most stable operating systems I have ever worked with. You can easily download it from official mirror sites that provide the disk-image file for free. The list of mirror sites can be found in Distrowatch.com as I described in my earlier post.

After downloading the image file (typically the have .ISO extension), you can burn it on a physical disk or you can create a bootable USB Drive, and boot your system with either of these two ways.

When You boot your System with the bootable media, your will face this welcome page:
