Things To Do After Installing CentOS 7

I have been using Linux OS for the past 10 years. I believe that I've finally found a system that's stable, easy on the eyes, minimum of pre-install packages, HDMI friendly, speed and reliability.

Well, the OS is CentOS 7. I was extremely surprise that everything works. I even install CenOS 6 on an old desktop But sadly some necessary packages were not pre-installed. If you're a regular Linux user , you should have no problem adding those packages, but if you're a novice or new implant from Windows or Mac, you will have to dig around to find all the info you need.

I decided to add these instructions to help my redears:

How to setup multimedia

You will need to also install the EPEL repository as nux-dextop depends on this for some of its packages.

Step 1: Install the nux-dextop repository

Run this command to install the nux-dextop repository.

yum -y install http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rpm

Step 2: Install the adobe repository

Run this command to install the adobe repository.

yum -y install http://linuxdownload.adobe.com/linux/x86_64/adobe-release-x86_64-1.0-1.noarch.rpm

Step 3: Install the desired packages

This command will download the flash plugin for Firefox.

yum install flash-plugin

This command will download the java plugin for Firefox.

yum install icedtea-web

This command will install Handbrake, VLC and smplayer.

yum install vlc smplayer ffmpeg HandBrake-{gui,cli}

The following command installs a decoder and codecs which are required to play certain types of media. Their usage may be legally restricted in some areas. Obtain legal advice if you are uncertain about the laws in your locality.

yum install libdvdcss gstreamer{,1}-plugins-ugly gstreamer-plugins-bad-nonfree gstreamer1-plugins-bad-freeworld

Install VLC

The default distribution of VLC includes a large number of free decoding and encoding libraries, avoiding the need for finding/calibrating proprietary plugins. Many of VLC’s codecs are provided by the libavcodec library from the FFmpeg project, but it uses mainly its own muxer and demuxers and its own protocols implementations. It also gained distinction as the first player to support playback of encrypted DVDs on Linux and OS X by using the libdvdcss DVD decryption library.

For EL7:

Install EPEL from http://www.unixmen.com/install-epel-repository-centos-rhel-7/ rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-1.el7.nux.noarch.rpm

For EL6:

rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm rpm -Uvh http://li.nux.ro/download/nux/dextop/el6/x86_64/nux-dextop-release-0-2.el6.nux.noarch.rpm

Now:

yum update
yum  install vlc

Installing (rpmfusion) Free and Nonfree Repositories

We have two separate software repositories:

• free for Open Source Software (as defined by the Fedora Licensing Guidelines) which the Fedora project cannot ship due to other reasons
• nonfree for redistributable software that is not Open Source Software (as defined by the Fedora Licensing Guidelines); this includes software with publicly available source-code that has "no commercial use"-like restrictions

Installation can be done either using a web browser, or via the command line.

Graphical Setup via Firefox web browser

1. First enable access to the free repository. For users of gpk (gnome package kit) or kpackagekit in Fedora that is easy and basically only one step: just click on one of the following files, depending on what distribution you use and then follow the default options that Firefox and Package Kit offer by clicking Enter a few times:

• RPM Fusion free for Fedora 20
• RPM Fusion free for Fedora 21
• RPM Fusion free for Fedora Rawhide
• RPM Fusion free for RHEL 5 or compatible like CentOS
• RPM Fusion free for RHEL 6 or compatible like CentOS

1. Once that succeeds, you can enable access to the nonfree repositories by clicking on one of the following files, depending on what distribution you use and then follow the default options that Firefox and Package Kit offer by clicking Enter a few times(¹):

• RPM Fusion nonfree for Fedora 20
• RPM Fusion nonfree for Fedora 21
• RPM Fusion nonfree for Fedora Rawhide
• RPM Fusion nonfree for RHEL 5 or compatible like CentOS
• RPM Fusion nonfree for RHEL 6 or compatible like CentOS

Once you clicked on above link Firefox will ask you how to Open the file. Here you can simply use the default and open the file with the default application Package Installer. Then Firefox will call Package Kit, which asks Do you want to install this file ?. Click OK to begin install; Package Kit then will complain about a Missing security signature; once you tell Package Kit to install the package nevertheless it will move on and install it. That's all.

Command Line Setup using rpm

To enable access to both the free and the nonfree repository use the following command:

• Fedora 14 to the most current:

  su -c 'yum localinstall --nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm'

• RHEL 5 or compatible like CentOS:

  su -c 'rpm -Uvh http://download1.rpmfusion.org/free/el/updates/5/i386/rpmfusion-free-release-5-1.noarch.rpm http://download1.rpmfusion.org/nonfree/el/updates/5/i386/rpmfusion-nonfree-release-5-1.noarch.rpm'

• RHEL 6 or compatible like CentOS:

  su -c 'yum localinstall --nogpgcheck http://download1.rpmfusion.org/free/el/updates/6/i386/rpmfusion-free-release-6-1.noarch.rpm http://download1.rpmfusion.org/nonfree/el/updates/6/i386/rpmfusion-nonfree-release-6-1.noarch.rpm'
