  1. hi, i’m installing CentOS 6.5 webserver, afer the install it restart and them he ask me for user and password, what i do to go to the graphic again? what user pass it asks?
    the only link (http://dev-random.net/how-to-install-a-centos-6-5-64bit-server/) that have something like that don’t tells how to start the system

    • Hi Marduk6666,

      So you are installing web server and want desktop? If this machine is coming only testing and developing use, then it’s totally okay, but if you try to setup real web server, then you shouldn’t install any gui or desktop.

      Did you selected any desktop packages on installation?

      It’s asking your username and password, example for root user:

      Or your normal username, like:

  2. Ty JR,

    I saw that for web server i can have the gui/desktop but i’m a newbie on linux so i will need the desktop so it can be more easy for me, now i did install the desktop with web server files so i will try to see if i can get it running

    As for the user/pass yes i did yty the root data and is that

  3. I had the exact me problem you did, but with a different package, it seems that the mirror I chose for my install didn’t have the firefox package the installer wanted and in the end I had no way of skipping and installing firefox later.

    It was not a network issue, just the repo not having that package, really annoying not being having an option to skip or specify an alternate location for the missing file.

    I recommend everyone just go with a minimum install.

  4. I had the same annoying issue with the missing firefox package. You have to start from the beginning as you cannot skip. The issue seems to be with the sonic.net mirrors. If you use the centos.org mirror the package can be found.

  5. Here’s what I don’t get:

    Why are the words, “Burn CentOS 6.6 Image to CD” on a web page entitled, “Netinstall Guide”. How is booting from a CD a netinstall?


    • Hi Bob,

      Maybe you should ask this question directly from the Red Hat (or CentOS) developers. Why they have netinstall.iso? And why their official guide have following text: Red Hat Enterprise Linux allows for installation over a network using the NFS, FTP, or HTTP protocols. A network installation can be started from a boot CD-ROM, a bootable flash memory drive…?

      One possible answer, you are talking about boot method and they are talking about installation. And yes this guide is walk-through howto install CentOS 6.6 over the network.

      And yes you can of course boot over the network using PXE. The following steps must be performed to prepare for a PXE installation:

      1. Configure the network (NFS, FTP, HTTP) server to export the installation tree.
      2. Configure the files on the tftp server necessary for PXE booting.
      3. Configure which hosts are allowed to boot from the PXE configuration.
      4. Start the tftp service.
      5. Configure DHCP.
      6. Boot the client, and start the installation.

      Every users can’t/want setup external tftp server and do PXE configuration when they are installing personal desktop linux or single server.

      If you want manage some larger environment and boot and install your system over the network, then I recommend you to use KickStart which is automated installation method to install Fedora, CentOS and Red Hat Enterprise Linux.

  6. I’ve successfully installed from this guide so thanks!

    My only issue now is I power up the virtual machine and it prompts me to install again. What do I do?

    • Hi Sean,

      You have to remove that install image (.iso) from your disks. If you use example VirtualBox, then it’s under storage section.
