CentOS 6.3 Features

CentOS Linux Distribution contains some new exciting features like.

  1. OpenOffice 3.2 has been replaced by LibreOffice 3.4, if you update from previous version of CentOS 6 using ‘yum update’ and have openoffice installed, the update will automatically remove openoffice and install libreoffice.
  2. Many drivers have been updated and improved in virtulisation.
  3. Upstream has deprecated the Matahari API for operating system management has been deprecated, and there’s new tools for moving physical and virtual machines into Virtual KVM machine instances. These new tools from Red Hat are virt-p2v and virt-v2v for physical-to-virtual and virtual-to-virtual migration, respectively.

  1. Lorenz Leitner says:

    Nice guide, thanks.

  2. Thanks for the guide. I don’t understand why the CentOS website doesn’t have a visual installation guide like yours.

    One question… Why in step #9 would you add another wired network adapter instead of selecting the pre-created “System eth0″ and click the “Edit” button?

    • Ravi Saive says:

      @Forrest – yes you can select system eth0 to configure your network. and the above example is just for further Ethernet and DNS configuration if you have any.

    • Macsek says:

      Hi Forrest,

      “I don’t understand why the CentOS website doesn’t have a visual installation guide like yours.”

      I thought is easy to answer:

      “Branded installation instructions and other documentation for “starting out well” are available for releases through CentOS 5; after that, a license change in upstream sources for this documentation presently rule out creation of “CentOS” branded variants.” http://wiki.centos.org

      Reading your question once again shows my citation is probably not the exact answer for your question, just related.

      Have a nice day.
      Macsek

  3. Nice article but what about create custom layout in step 13 please help me up…

  4. pramod says:

    nice guide

  5. amaresh says:

    thank you …Helpful

  6. Hassan says:

    Hi,

    Thank you for the guide.
    But i have one question, i followed all the steps, and after restarting the machine, i lost the graphical interface (i choose web server as installation just like you), and i have only command line interface.
    Can you help me please.

    Thank you in advance.

    Best regards,

    • Ravi Saive says:

      @Hassan,
      Don’t worry just connect to internet and install graphical interfaces KDE or GNOME with YUM command. Login as root and run the following command.

      For KDE

      yum groupinstall "X Window System" "KDE (K Desktop Environment)"
      

      For GNOME

      yum groupinstall "X Window System" "GNOME Desktop Environment"
      

      If you don’t have internet, then open the file /etc/yum.repos.d/CentOS-Media.repo with vi editor, change the “enabled=0″ to “enabled=1″ and mount the CentOS installation DVD under /media/cdrom/ and run the yum commands again.

      If you still having any problem, comment here.

      • Gita says:

        Hi Ravi,
        I had a VM with CentOS 6.3 installed in my PC (Windows on host). It had gnome, and I wanted to use kde. I used “yum groupinstall KDE”. It had a warning: no kde-desktop package available…”. Although this installed many kde features but still didn’t have the option to change to kde (no such option during login session. When I tried “KDE” at prompt it replied: no such command). I then found this site and used “yum groupinstall “X Window System” “KDE”. I restarted my VM and looks like it started the boot process and then goes black…probably some conflict. Any help/suggestion would be greatly appreciated.

  7. Hassan says:

    Hi,

    thank you for your help.
    I have just to notice that i use vmware player, and the problem of connectoing VM to the physical machine is causing (in part) the choice of the type of virtual connection between the VM and the physical network.

    So, how can i mount the device : cdrom, if i’m using the VM?

    Thank you.
    Best regards,

    • Sanjay says:

      Hassan,

      If you are using VMWare, you could add it in as a device from VMWare Workstation Manager and it will appear as one of the devices if you double click the ‘Computer’ icon in your GUI.

  8. Darwin says:

    Just an fyi…the most recent .iso files are not bootable, please review:
    http://wiki.centos.org/FAQ/CentOS6#head-c44e0ab6188ce37ff04eb13dbb34e3f61d08ddab.

    Download and run the CentOS-6.3-x##_##-netinstall.iso, and eventually you’ll have an option to install from several sources, choose DVD, The installer looks for CentOS-6.3-x##_##-bin-DVD1.iso in the DVD. What a PITA, I don’t like the extra step.

  9. bryan says:

    I currently have 2 internal hard drives on my computer. One already running windows. In the installation could you select the hard disk in which CENTOS would be installed?

    • Matthew says:

      Hey thanks for this, definitely helpful. Any idea how I go about retrieving the contents from the second dvd .iso? I think I need some of those packages in order to install the drivers for my graphics card?

  10. Sanjay says:

    Ravi,

    Very succinct and clear. Thanks.

  11. clark kent says:

    very nice tutorial, can you help me how to configure in making virtual host? thanks

  12. Vivek says:

    Just installed 6.3 32 bit using the bootable disks created using the 2 iso files provided for download on CentOS site.
    I have Two questions.
    1- How to configure Broadband connection? (I am having BSNL, India, modem based broadband connection that required user/pwd to connect through my land-line phone)
    2- What is the use of Disk 2 iso image that is provided?
    The installation got completed with the first disk itself and it never prompted for disk 2 iso image.
    Thanks in advance.

  13. syazwan says:

    great tutorial, but I have problem on step 2…..If I click yes,discard any data…will it remove my data on the hard disk? I am planning for dual boot.

    • Ravi Saive says:

      YES! it will discard data on selected disk. If you’ve planned for dual boot make sure you must have empty drive for your centos installation.

  14. Jerry Billygoat says:

    The installation is easy. However, I am installing in text mode. It never prompts for hostname, disk partition instructions, network setup, package selection (samba, ftp, apache, php, mysql, etc.) Do I now install individual packages after the initial install?

  15. clark kent says:

    hi sir can you help me pls…i already install centos 6.2 and i already configure the

    network by putting static ip address but still i can not connect to internet…

    when i login as a root and typing links to browsing internet..still the message appear host not found.

    can you help me sir what are some steps to configure so that i can connect to internet

    • Ravi Saive says:

      Have you added dns entries in /etc/resolve.conf file? if not, add the entries and try to ping any host and see the results.

  16. clark kent says:

    hi sir thank you for your response…sir i already added entries in resolve.conf but still i can not connect to internet.. even in local connection i cant ping the ip address that i put in centos server…sir what are those possible configuration…thank you very much sir

  17. Rajeev says:

    Hi,

    I tried all the steps to install CentOS 6.3 on a desktop (with the default webserver option selected) and i have added mysql server additionally. After installation is complete my desktop restarted and asked for logins. I typed ‘root’ and password but it started showing the below line repeatedly instead of loging in.

    [drm] nouveau 000:04:00:0: no native mode, forcing panel scaling
    [drm] nouveau 000:04:00:0: no native mode, forcing panel scaling
    [drm] nouveau 000:04:00:0: no native mode, forcing panel scaling
    [drm] nouveau 000:04:00:0: no native mode, forcing panel scaling

    Can any one help me please. Thanks,

    I used the same DVD and settings to install CentOS 6.3 on Oracle VM, it works fine. I was even able to run a web based application developed using Jboss & mysql on the VM.

    • Ravi Saive says:

      Add the following to kernel line in /boot/grub/menu.lst file, will fix the problem.

      drm_kms_helper.poll=0
      

      or create a config file “modprobe.conf” under /etc/modprobe.d/ directory and add the following line and save.

      options drm_kms_helper poll=0
      

      Restart the server.

  18. Rajeev says:

    @ Ravi:

    Thank you. It works. I have added drm_kms_helper.poll=0 to menu.lst

    Thanks a lot.

  21. fillipe says:

    Hi,
    I’m trying to install centos 6.3 at a new pc in my lab, but the installation stop after step 1 and my screen gets black. Do you have any idea how i fix that problem?

    • Ravi Saive says:

      I think video graphic driver problem, from the grub select “Install system with basic video driver” option and proceed installation and let me know what happens next.

  22. Nada says:

    Hi,

    I used the same version of CentOs to install it but i only get the command line after installing (no graphic interface). Also during the installation i never got to see all the steps u screenshoted. Why ? Can you provide me an available link where to download the same version as yours ? Thanks

    PS : i did try to edit the CentOS-Media.repo file but it wont work at all

    • Ravi Saive says:

      The download links are already provided in the article. If you are looking for GUI then install GNOME or KDE. Use the following command to install any of the one.

      # yum groupinstall "X Window System" "GNOME Desktop Environment"
      OR
      # yum groupinstall "X Window System" "KDE (K Desktop Environment)"
      
      • Nada says:

        Hi thanks for ur reply.
        I found out i cant install it with the GUI, it says i dont have enough ram to do so.

        I did type those commands but it seems i dont have an internet connection because i get this error :

        pycurl error 6 – couldn’t resolve host ‘mirrorlist.centos.org’

        I did try to edit the repo.conf, it didnt help to solve the internet problem.

        Right now im installing the 5.9 version and it seems to work fine (GUI)

        • todd says:

          Nada, I ran into the same issue in a VM. I gave the VM 512MB by default, but the installer requires minimal 652MB ram on the guest in order to do GUI install. I adjusted the VM with this minimum req , reran the install and was able to install via GUI.

          • Nada says:

            Oh really ?! thanks for sharing this with me. I’ll definetly try this tonight and let u know !

          • Nada says:

            Well Todd i must say thank you so much ! I finally got to install CentOS 6.3 with GUI ^^ Thanks again for ur tip !

  23. S V Prasad says:

    I installed centos 6.3 on a Lenovo H525s core i5 3GHz, 4GB RAM and 500 GB Win 8 Desktop by creating 146 GB partition. The bios supports UEFI. After installation when I restart the system it always goes to windows only. The GRUB boot loader is not able to see the linux part. When I searched the forums many are saying it is due to MBR / GPT / UEFI incombatibility. If that is the case then I may have to add GRUB 2 support. Where can I get GRUB 2 inclded centos 6.3 distribution. My second query is since i am not able to boot into Linux directly I used rescue mode and am able to get into linux command mode. From there if I trype startx it goes into GUI mode but my keyboard and mouse hangs. Could any one suggest me steps to fix any of these issues. Thanks a lot for any help.

    • Nagendra says:

      I got the similar problem. I could not see the option to go to Centos. Did you find the solution. If so may you post here for me please?

      • S V Prasad says:

        Short answer – Solution for Lenono desktop could not be found. No success yet. Long answer – Try the following ifyou have time:

        1. There is a Centos 6.3 minimal install with Grub2 support at least that is what the website mentioned. This supports few hardware platforms. If you could download and install and if that works for your platform then you should be fine. It did not work for my HW platform.

        2. GRUB2 source code is available for download. If you could compile and integrate with Centos 3 it might work. Again it did not work for me.

        3. Create three partitions. One with Windows, another one with Centos 6.3 and third one (may be small one) with Fedora latest release (which already has support for Grub2). If using Fedora your system is able to accept the hardware and if you could see boot option then you can modify by it to point to centos as well. This I did not have time to check completely. You can try and see for your self.

        4. Last option is wait for Centos 6.4 with Grub2 full support. I do not know when.

        Sorry I could not be of much help.

  24. Manoj says:

    i downloaded CentOS-6.3-x86_64-bin-DVD1to2 and i dont get the GUI! is it a minimal? how do i download the ‘oftware Development Workstation’, is there one?

    Hi,How Can I install Updates & 3rd party tools (VLc) Without Internet Connction….PLZ Guide

    • Ravi Saive says:

      No, you can’t install updates or any third party packages without internet connection. You must have connected to internet in order to download updates or packages.

    Nice guide, thanks.

  27. Hello I Know It’s My Second Comment on Same Post But I’m Totally Confused,

    I want To Install Centos But Have a Serious Question “Will I Loose my All Data in Installation”

    If Yes Then Please Tell Me Some Method to Protect it – Approx Size of Data is 100GB.

    Thanks Your Support is Appreciated

    • Ravi Saive says:

      You mean, you have dual boot environment where you like to install CentOS with windows. If yes, then first allocate a drive with free space and then install the centos on that free space drive.

      • No Ravi I want to Completely Remove Windows And Install CentOS Is There Anyway to Save my Data.

        • Ravi Saive says:

          No, you will not loose any data, if you install the centos in windows drive after removing existing windows.

            Dear Ravi,

            We require to install the Cent OS 6.3 i386 in VMware Env. In cmd line the installation is completed. I can only see very less files in /etc. How to install the 2nd DVD Cent OS. Please advice.

            Thanks in advance,

            Balaji

          • Ravi Saive says:

            firstly, must you have selected minimal packages during installation, so you get less files in /etc. If you want to install other packages you can use yum command to install it. If you not aware of yum, you can take look at the yum guide.

    can u please explain the differences between

  31. jenko says:

    Hey thanks for this tutorial. Will it apply for version 6? The part the confused me a little was the ‘wired tab’. I’m not sure if we need that. We need our set up to be used to format hard drives with Linux for Digital Cinema distribution and it will have a a CRU dock attached with a eSata connection to be used as a network drive. It’s a new machine and already has 7 32bit installed on it. Should we keep that on a parition? It will not be connected to the internet, only by the network to my DCP creation machine. We will be loading, or loading content to or from a hard drive in the CRU slot. What’s you opinion on how we should install?

    I am trying to download centos 6.3 from mirror web sites. However the directory is empty and it refers to the latest version 6 which is 6.4. Is version 6.3 deprecated and it is encouraged to use version 6.4 ? I am new to centos and I was a bit surprised that point releases are deprecated so fast.

    Here is a web site example:
    http://mirror.stanford.edu/yum/pub/centos/6.3/
