Software Installation on CentOS There are given a list of 20+ softwares which can be installed on CentOS. All installation pages have prerequisites and images so that you can easily understand the installation process. CentOS 7 ships with Python 2.7.5 which is a critical part of the CentOS base system. SCL will allow you to install newer versions of python 3.x alongside the default python v2.7.5 so that system tools such as yum will continue to work properly. In order to enable SCL we need to install the CentOS SCL release file. This tutorial explains how to install Apache on CentOS 8 and how to configure virtual hosts easily. From all the web servers available, the Apache Web Server is probably one of the most popular ones. Developed by the Apache Foundation, Apache is so popular that it runs 70% of all the webservers online. It is a reliable and secure web server that every system administrator should know.

Minimal install only installs a basic version of CentOS with only a minimal amount of additional software. This will substantially reduce the chance of the system being affected by a vulnerability. After the system finishes installing and you log in for the first time, you can use the Yum package manager to install any additional software you need.

This is a quick step-by-step guide with pictures to assist you in installing latest version 7 of Centos Linux Operating System. For this, a user needs to have some basic understanding of how Linux system works and also some knowledge about partitioning mechanism.

We shall keep this quick guide as brief as possible.

You can download Centos 7 from web and either make a bootable USB or DVD drive for installation. We assume that, you have a new computer or no operating system installed. Please follow the below wizard to install Centos 7 −

Boot Screen

The moment you boot from Centos setup media, you should see the following screen −

At this stage, we cannot use our mouse. We need to select first option Install CentOS 7 using our keyboard and then press return.

Choose Installation Language

Next screen should appear and prompt you to select and use an installation language for this installation process which you’re comfortable with.

For this article, we shall select English language option. However, you can also choose any other available language of your choice.

Choose a language category and its subcategory and then click on Continue. Yes!! we can now use mouse!

Installation Summary

You should now see a screen with title Installation Summary. Actually this window has all the options that user can configure.

There are three main categories −

Localization
Software
System

We shall look into all options one by one.

Localization

These setting options deal with the locality of the user which in turn helps the system to provide the user a customized feel.

Date & Time

This window provides options to set regional values of user like his/her region (locality), city and local date & time.

Keyboard Layout

This option is about setting up your keyboard preferences where the user can choose a keyboard layout which he/she is currently using it.

Language Support

This option provides us the ability to add any language support to our Linux system.

Software

This category has options that deal with software being installed.

1.Installation Source

Here, we are providing a source of installation files for Centos 7. It can be directly plugged in a suitable device like − USB, HDD or CDROM or a network path. We can also provide repositories to install additional software.

2. Software Selection

Like any other Linux flavors, Centos 7 offers us huge list of software to select from. By default, it should go with the minimal installation that does not even has GUI. For our example, we shall select GNOME Desktop environment.

Other packages to support a desktop environment can also be chosen, E.g. Office suite etc.

System

This category contains options for the system being installed. It deals with the partition schema for the host and defines its identity over the network.

1. Network & Hostname

Let’s first learn about network options. This window has hostname by which this system should be recognized over local network. Left hand side window shows available network options like ethernet or wifi.

2. Installation Destination

This window can be said to be the most crucial one. Here, we can select the disk on which the system needs to be installed.

After selecting the disk, we are providing two options to format it. These are called auto-partition or manual partition.

The auto partition option automatically partitions and formats the hard disk with assumed best option and user does not have to do anything.

Or if the user has some experience with Linux partitioning and wants to customize disk allocation, he/she can choose “I will configure partitioning“ option. User needs to choose a mount-point and provide desired capacity” −

And need to provide its file-system. For our example, we are formatting the partitions with ext3 file system −

Linux system should have at least two partitions. One for mounting the system, i.e. / root for the system and another for swapping swap partition.

Swap partition should be double than that of main memory available with the computer. After you decide about all your partition schema, the system will give you a summary report for what it is going to do like the sample screenshot below:

Click on Accept Changes to admit changes. The final window with all things setup should look like this −

You should now click on Begin Installationto start the installation process. The next window should immediately appear.

This window has exclamation sign on root password and on user creation. This window is prompting us to assign the root password and create at least one user. Though being optional, but for ease of use after installation, we shall proceed with them now. First we click on root password −

Provide a secure root password here and click on done. Then you should be sent back to the previous screen again. Click on user creation and the following screen should appear −

Provide all the credentials and click on done. This will be the default user for the system. Now, when we come back we see that all exclamation signs are wiped out.

Wait until all system files are loaded and installed into your system. After installation is finished, the system should prompt you for a reboot –

Make sure you remove all installation media or change the boot sequence to boot the newly installed Linux system. Now, you should see something like this −

Press ‘return’ (or enter) on the first option and let new operating system load itself.

Post Installation

After system is installed successfully it should do some post installation activities. You should see the following screen −

Click on License Information and accept it.

And click on Finish Configuration to finish the initial configuration.

Next you’ll be prompted for kernel dump option, stay with default values if you are not aware of the stuff and click on Forward.

Click on user and provide credentials of the user we created at the time of installation –

Next you should see Centos 7 desktop with a window prompting you to select your system language.

For the disclaimer part, images have been cropped and scaled to fit. Advance users can also install Linux without using GUI mode and can also customize the installation at the install time.

If you’re installing Linux parallel to other operating system, please do not forget to read about Linux boot loader and its work philosophy. If the system has come with pre-installed operating system, then there are chances that you never see the Linux boot loader unless some changes are made into the BIOS settings. Do read those instructions before proceeding.

Happy Linux!

So you’ve made the switch to Linux. Or you’re thinking of making the switch. But you have questions that might be stopping you from fully diving in. One of the biggest concerns most new users have is, “What software is available and how do I install it?”

It’s a reasonable question. Why? For the longest time, Linux suffered from a stigma that applications were scarce, and that the few available options were a challenge to install. I remember, back in the early days, having to compile software from source packages—which would lead to a seemingly endless circle of missing dependencies. It was frustrating, but doable. That frustration, however, turned a lot of people away from Linux.

Fortunately, those days are long since past, and installing any of the available software titles (of which there are many) on Linux is no longer such a headache.

What operating system do you use? For some, that question may as well be posed in Latin or…

Package managers

This is one of those topics that tends to confound most new Linux users. A package manager is a sub-system on Linux that, as the title says, manages the packages (software) on your computer. It’s a crucial component of Linux, in that it keeps track of everything installed; downloads packages; ensures all packages are installed in a common location; helps to upgrade packages; resolves dependencies; and keeps users from having to install from source code.

The biggest point of confusion is that there are numerous package managers available, but only one can be used on a distribution. In fact, distributions are differentiated, primarily, on which package manager they choose. For example: Debian and Ubuntu (and its derivatives) use apt; Red Hat Enterprise Linux, CentOS, and Fedora use yum; SUSE and openSUSE use zypper; and Arch Linux uses pacman. There are more package managers out there, but this is a good place to start.

Each package manager works with a different file type. For example, apt works with .deb files and yum and zypper work with .rpm files. The apt package manager cannot install .rpm files and neither yum or zypper can install .deb files. To make matters even more confusing, Ubuntu (and its derivatives) uses the dpkg command for installing local .deb files, and Red Hat (and its derivatives) use the rpm command to install local .rpm files.

Installing a downloaded file

I know, I know… I said one of the benefits of modern Linux operating systems is that you don’t need to install from a downloaded file. That being said, I want to start here. Why? There may be times when you find a piece of software not available in your distribution’s “app store.” When that occurs, you’ll need to know how to install that application manually. I will say that, for everyday, average use, it’s a rare occasion that you’ll need to do this. And even if you never do install using this method, at least you’ll have a very basic understanding of how it works.

Here, we’ll demonstrate using the latest release of Ubuntu Linux (as of this writing, 17.10). Most package managers install in similar fashion (with slight variations on the commands used). Let’s say you want to install the Google Chrome browser on Ubuntu. You won’t find this particular browser in the Ubuntu Software tool. To install it from the command line, you must download the correct file. As stated earlier, the correct file for Ubuntu will be a .deb file. So point your browser to the Chrome download page and click the Download Chrome button. The good news here is that your browser will be detected and the Chrome download page will know which file you need. Click the ACCEPT AND INSTALL button and a new window will appear, giving you two options (see below).

You can either save the file to your hard drive (and then install via the command line), or open the file with the Software Installer. It is important to understand that not every distribution includes the latter. If you do not get the Open with option, then you’ll have to install from the command line.

Let’s first use the Open with option. Make sure Software Install (default) is selected and click OK. The file will download and then Ubuntu Software will open, giving you the option to install (see below).

Click Install and you will be prompted for your user password. The installation will complete and Chrome is ready to use. You can close the Ubuntu Software tool and open Chrome from the Dash.

But what if you don’t get the option to install with the GUI tool? Then you have to select the Save File and run the installation from the command line. Don’t worry, it’s not that hard. Here are the steps to install the latest release of Chrome, on Ubuntu Linux, from the command line:

Click on the square of dots at the bottom of the desktop
When the Dash opens, type terminal
Change into the Downloads directory with the command cd ~/Downloads
Install Chrome with the command sudo dpkg -i google-chrome*.deb
When prompted (see below), type your user password and hit Enter on your keyboard
Allow the installation to complete

Installing from the GUI

This is where things get very easy. To install from your distribution’s GUI, you only need open up the tool, search for the software you want, and click Install. Say, for instance, you want to install the GIMP Image editor. To do that, open Ubuntu Software and type gimp in the search bar. When the results appear, click on the GIMP entry, click the Install button (see below), and (when prompted) type your user password. Wait for the installation to complete and your new software is ready to be opened and used.

Bottom line: it’s all easier than it seems

Centos Install Software From Dvd

Installing software on Linux isn’t nearly as hard as you might have thought. Yes, there may be the rare occasion when you need to install something from the command line, but even that isn’t much of a challenge. Besides, chances are, you’ll never have to install software outside of the GUI front end.

Do remember, if you use a distribution other than Ubuntu (or its derivatives), you’ll want to do a quick bit of googling to make sure you understand the differences between the apt package manager and the one used on your desktop.
