CentOS 6.10 Netinstall – Network Installation Guide

CentOS is a most popular and widely used Linux distribution from the RedHat Enterprise family. This CentOS 6.10 release is based on the upstream release Red Hat Enterprise Linux 6.10 comes with bug fixes, new functionalities & updates.

It is strongly recommended to read the release notes as well as the upstream technical notes about the changes before an installation or up-gradation.

Upgrade CentOS 6.x to CentOS 6.10

Those who looking to upgrade from previous CentOS 6.x to a new major CentOS 6.10 version, they can simply run the following yum command to upgrade their system seamlessly from any earlier CentOS Linux 6.x release to 6.10.

# yum udpate

We highly suggest you to perform a fresh CentOS 6.10 installation rather than upgrading from other older CentOS versions.

In this article, we will take you through the steps of performing a minimal CentOS 6.10 network installation, where you install a very minimum set of software, necessary for booting the kernel and performing basic functions on your server, without a graphical user interface (GUI). It allows you to set a foundation for building a future customizable server platform.

Download CentOS 6.10 Net Install

If you’re looking for fresh CentOS 6.10 installation, then download the .iso images from the links provided below and follow the installation instructions with screenshots mentioned below.

  1. CentOS-6.10-i386-netinstall.iso [32-bit]
  2. CentOS-6.10-x86_64-netinstall.iso [64-bit]

CentOS 6.10 Network Installation Guide

1. First start by downloading the CentOS 6.10 Network Install ISO and then create a bootable USB stick using LiveUSB Creator called Rufus, Unetbootin or terminal based Bootiso.

2. Next boot your system using the bootable USB or CD, at the Grub menu, select Install or upgrade existing system and hit enter.

8. Now configure the CentOS 6.10 Netinstall URL, it is recommended to choose a nearest mirror from the available CentOS mirrors list.

Example mirror.liquidtelecom.com
  1. http://mirror.liquidtelecom.com/centos/6.10/os/i386/ – [32-bit]
  2. http://mirror.liquidtelecom.com/centos/6.10/os/x86_64/ – [64-bit]

16. Now you need to specify the type of installation you want. Read the descriptions of the options carefully and select the appropriate one. If you want to use the whole disk space, choose Use All Space, but to perform a custom installation, choose Create Custom Layout.

Select CentOS 6.10 Installation Type
Select CentOS 6.10 Installation Type

17. The installer will review and modify partition layout. If everything is ok, clik Next.

  9. Hi Ravi,
    I appreciate your efforts.
    I have installed the first dvd only. I am facing problem in installing tata photon max. Is installation of iso-dvd-2 necessary for running internet connectivity, necessary.

    Pl help.


    • Dear Ranvir,

      The first DVD is enough for installing all needed packages, the second DVD is optional, but regards to internet connectivity, you need to install some drivers related to your data card provider.

  10. Do you have any ideas on how to customise the Basic server setup after i install Cent OS 6.5 using ISO files? i don’t want to go with YUM installer. Please advise. Thanks

  11. hi ravi please tell me complete samba4 installation steps in centos please give EX:

    host name:dc1
    doman name :laxmi.com
    my system ip
    sub net mask
    d gate way

    thank u

  12. I am getting error like this when try to install GUI mode

    files contains prasing errors: file://///etc/yum.repos.d/iso.repo

    [line 2]: name-pkgs

  13. Hi Ravi,
    Thank you for your quick response. How do I access the web using Centos 6.4. I set it up as a basic server with minimal installation. Everything is in command prompt and I dont have a deskktop like I would with Windows..

    I have been asked to access the web interface? How do I do that?

    Kind Regards

    • Bro, I am confuse with your question, are you mean to access Desktop? or a Web Server? If it’s desktop, just install KDE or GNOME desktop environment. Just run the following command on the terminal to install Desktop.

      # yum groupinstall "Desktop" "Desktop Platform" "X Window System" "Fonts"
  14. Hi Ravi, maybe you can help me out. I have never in my life used Centos 6.4 or any type of linux system. I am used to using Windows, none of this command prompt. I have no idea what I am doing.

    I have to install a basic database server for my manager so that another company can access us through ssh etc.

    Ok so when I access the login via route I type: ” ip addr show”, it shows one called eth0 and another one but it says eth0 state is down, so I then type: “ifup eth0” and then it says “Determining IP… Done”. When I then typE: “ip addr show” it then shows eth0 state as up and it allows me to ping websites.

    The problem I have is trying to obtain the IP address because it just will not show it a tall and to make matters worse everytime I turn the computer off and then back on I have to keep repeating the process of ifup eth0 to turn it on… I am finding this really frustrating.

    I know nothing about GUI interfaces or YUM. Far as I was concerned you install centos 6.4 and away you go, this doesn’t seem to be the case. :(

    Kind Regards,

    Stressed and fed up man.

  15. Hi Ravi,

    Thanks for the great and precise article. Can you please spare some time to answer these question.

    1. How to add more features (softwares, packages, rpms) to an existing (basic) installation. I got a whole rack with multiple servers and most of them have basic installation. I need to add more features e.g. graphical desktops, vnc etc. How can i do it ?

    2. How to create an offline repository of installation media. The purpose is since my servers will be behind firewall in Local area network and most probably Internet will not be available or will not be allowed. Therefore, if some offline media repository is not set, i may not be able to execute ‘yum install package-name’. Please guide or redirect to some post.

    Thanks in advance.

    • For your both the questions, simply create a local repository with complete CentOS package set and allow clients to use these repo as base repository to install packages using yum command. For about setting local repository, please search for the article using our search form.

  16. i have this iso image CentOS-6.5-x86_64-bin-DVD2.iso.But virtual machine give this error when i attached it.

    Fatal:No bootable medium found!System Halted

    • Bro, the first ISO images contains bootable files that allow VM to boot from the first image. Please insert your first ISO image, not second one..

  17. Just wanted to say THANK YOU, it is really awesome that you took the time to write this article, thank you for contribution to the knowledge base.

    Awesome work!

    I tried CD DVD but it didn’t work then I used Local HDD which gives me options like dev/sda1 , dev/sdc1, dev/sdc2 but I tried all these options but i get error that drive was failed to mount or something ( I don’t remember exactly ) this server already has 6.3 but I want to use 6.4. Any help would be greatly appreciated.

  30. I’ve installed CentOS 6 a couple times on the same system, once on my own and once following this and then another step-by-step guide. Both times my installation skipped steps 20 & 21. I’m not sure what I’ve done wrong, as I’ve followed what it said exactly. Luckily, it seems I can add them later, but I’d really like to figure out why it skips the packages step.

  31. hi Rav, i want to install linux64_11gR2 on CentOS 6.5 or oracle linux 6.4, which option should I choose between Basic server and Database during OS installation…and why?

    • If you’re planning to install Oracle, then better go with Oracle Linux 6.4 because it has official oracle repository where you can easily install oracle packages via Yum.

  32. hi Ravi,

    i downloaded this file, “CentOS-6.4-i386-bin-DVD1to2.torrent”. i notice it has 2 ISO files, namely:

    1) CentOS-6.4-i386-bin-DVD1.iso

    2) CentOS-6.4-i386-bin-DVD2.iso

    i too notice there are 3 txt files, and 3 asc files.

    if i burn to DVD, should i include the 3 txt files and 3 asc files?

    based on what i read above, i just need the DVD1 ISO file only, right?

    Can you provide some tips to help me to finish this installation?

    Thank you very much.


  38. sir this is what im am up to..


    – Installation must have /u1 and /u2 directory, with its own partition each.
    – SWAP space must be at least 1024mb
    – Server must not have any GUI

    Rules of engagement

    – All configuration file must be accessible through /etc/
    – All installation file packages must be in binary form or source form usually (.tar .tar.gz, .gz, .bzip, .tgz), you can’t use yum, up2date, apt-get, so use of rpm, dpkg are not allowed.
    – All download and installed service will be put under /usr/local/
    – Use “scp” to transfer files to the machine from your pc, or use “wget” to directly download the “binary/source”
    – After install of service removed binary/source from /usr/local/ or moved it to other volume.
    – Backup all configuration file – that your going to edit.
    – All services must run as nobody –
    – All HTML files and database files must be in /u1 directory.
    – /u2 will be used for backup files only.

    Do the following –

    – Install Linux – without any services except for SSH.
    – Create Account
    – Change Password
    – Configure Sudo – for you to gain root
    – Configure SSH to not allow root login
    – Login through SSH –
    – Install and Configure Mail server using sendmail – authenticate against passwd
    – Setup POP/IMAP – authenticate against passwd
    – Setup Apache with HTTPS and Module support and logging to /var/log/apache
    – Install and Setup Webmail – use Squirrel Mail or Open Webmail
    – Put /usr/local/bin in your user path
    – Configure log rotate to rotate logs in /var/log/
    – Write a script to check the HTTP process is running and will send mail if it is not running.
    – Put the script inside the crontab and have it run every half an hour
    – Services HTTPD, MySQLD must autostart when machine boots up.
    – Create script to backup /u1/etc /var/log and place backup file in /u2
    – Put script in /u2 backup file must have the following format, hostname-“backup.dateofbackup.tar.gz”
    – Schedule the backup script to run midnight every 3 days.
    – Configure IPTABLES to deny all and only allow connection to port 25, 80, 443 and 22.

    what is the step by step things to do?? im done on the other part like creating users, installing httpd, php , mysql but i think something is wrong.. im not satisfied .. i dont know if im doing it right..

    • This is a very huge list of custom requirement. Will help you out, but will charge per hour $35. If you agree will discuss more..

    • Is internet connected to system? If yes, you need to add a DNS in /etc/resolv.conf file. For example, you should add.


      Replace with your DNS IP.

  56. Hi Sir,

    I have installed CentOS 6.4 in vmware but i didnt get GUI mode.. what should i do …i use startx and init 5 but no luck..below is the output..

    -bash: startx: command not found

    init 5

    Retrigger failed udev events [OK]


    • Do you connected to internet? if yes download yum package for your distribution and install it using rpm -ivh command, and then install X windows using YUM package manager.

          • Hi Ravi,

            I ran init 5 on command mode but i got below output…

            [root@HadoopCentOS ~]# init 5

            Retrigger failed udev events [OK]

            Please advice


          • To fix this error, you need have X Windows desktop environment like Gnome or KDE (I am guessing you want a KDE). Run this command.

            # yum grouplist

            Then find out what X groups available. For example, you want to install KDE, type the following groups.

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

    • There are lots of factors involves like if you already setup website and its accessible from LAN. May I know here how you accessing your website? means using IP address or localhost from the browser. If port 80 is opened, can you able to telnet it locally or remotely? Is your domain/website resolved to your static IP address? Check all these things and let me know.

      • yes sir i can run using my localhost ip and i can view my website in lan. using my local ip

        i have opened the port 80 i m can local telnet it ,i use putty for installing packages for diffrent computer in lan

  59. Is there any way to install from network assuming there is no linux machine ?
    That means I want to install my first Linux machine from network.

  60. Hello Ravi

    I have installed everithing and it works. But during de boot process I get an error (after leaving the splach screen with the escape key) appearing in red in the screen(I guess a service wich can’t start). But as soon as the graphical service start it’s not possible anymore to read the message. Of course I can readt it in the log files, but have you a trick to return to the boot screen directly and see it ?


  61. I just done a fresh install of CentOS 6.4 Server, with an KDE Desktop, on a Dell Optiplex 755 with 2GB DDR2, 1TB Hard Drive & nVida Video. After reboot I get the Command Line only & when I go to login I’m getting an constant “login incorrect” I’ve double checked Username & Password still won’t work, any suggestions?

      • Thank you, I found I had the username wrong was using non-administrator instead of “root” for login, then my password. New issue is I can’t get online tried pinging google.com, got nothing, but this error “ping: unknown host google.com. Not sure how to fix, should I be reading something since I’m trying to switch from windows to make an PXE Server using CentOS 6.4? Like the Command Lines I should be using.

  62. Thanks for your instructions. I am a CentOS newbie. Followed your instructions using Live CD; used text mode. Install seemed to go okay. Pretty sure that I did not include any GUI packages (on purpose; I just wanted to maintain the server using command line). Anyway, I created ifcfg-eth0 to use DHCP. But whenever my ethernet cable is plugged in (and this cable and ethernet jack work fine with other computers), my screen goes black within 5 minutes; cannot even restart with Ctl-Alt-Del. And before the screen freezes, I cannot ping other machines on my LAN (“network is unreachable”); but pinging localhost works fine. My machine’s Ethernet controller, as listed by the command lspci, is a Broadcom NetXtreme BCM5755 Gigabit Ethernet PCI Express (rev 02), vendorID:deviceID = 14e4:167b.

    I don’t know how to troubleshoot this problem; any ideas?

  63. My problem is that I have been trying to install Centos 6.4 from the i386 bin-Dvd’s and wanted to do a “create custom layout” in terms of setting up partitions.

    Unfortunately after setting up the boot partition as the mount point and forcing it to be a primary partition I keep getting error messages which tell me I have to set up a root partition before I can proceed.

  64. Hi Ravi,
    Thanks. Very useful.
    I have question as I am new to Cent OS (I am Ubuntu user). Is both ISOs required for installation ?

  65. Hi Ravi,

    I have installed centos 5.9, I want to install PowerDNS on it.
    So can you tell me the proper steps for that?
    I really need it as soon as possible.

  66. Hi there Ravi

    I’ve installed CentOS 6.4 successfully…now with the boot up it’s requesting an login. What am I suppose to put there…? I’ve tried adding the host name or the boot loader but it’s a no go

  67. Thanks. But I have a problem i am confuse of you are Upload Two ISO image First is “CentOS-6.4-i386-bin-DVD1” and Second is “CentOS-6.4-i386-bin-DVD2” . Which one i Download for install CentOS-6.4-i386-bin…….

    Please Tell me I am waiting for your reply

  68. I am trying to install centos 6.4 x86_64 in a intel corei5 (lenova Think Centre) Installation is OK for Basic server installation and final reboot ends in log in screen. However when I choose X window system for GUI interface, the final reboot says “error 1962: no operating system found”. In the same machine I have installed i386 and used it in GUI mode. Can you help me to solve this

    • Hi Jagannathan,

      I am facing this same issue for Cent OS 6.5 on a Lenovo machine. Could you guide me in the right path?


  69. Hi Ravi, when I install centos I don’t get any option for desktop or anything, it just goees to install after partition. I’m just starting in linux

    • you mean system starting in command line mode? If yes, install X windows managers like GNOME.

      # yum -y groupinstall "Desktop" "Desktop Platform" "X Window System" "Fonts"

      If you like to install KDE, then use:

      # yum -y groupinstall kde-desktop
  70. Thanks Ravi, very useful. This is my first time installing this, After booting from cd it gave me an option on the desktop saying “Install to Harddrive” . This is the one I am installing.

  71. during initial installation ,will install need to download system files from internet? , or does everything for installation come with the ISO?
    (my English is not very good)
    thank you
    please reply soon

  72. Hi,
    I have just bought a Dell CloudEdge C1100 .
    I am trying to run Openstack. I was using CentOS 6.4. But I had an issue with the OS complaining about it could not find the ISO9660 media etc. and aborted after setting up the partitions and LVM. So I went back to 6.2 and I am upgrading this way. The question is once I have got the OS to a State I like what’s a good backup stategy Clonezilla or good ol’ tar and dump?

  73. in step number 20, what is the different between basic server, virtual host, web server and the others options?…

    what are the specifications and description for each of these???

    good post!!

  74. Hi Ravi,
    Nice post, much needed!!
    Just one question – can I copy both iso on a USB drive and then install using that or I have to make the USB bootable with some utility like UNetBootIn.


  75. i have installed cent 6.4 ..but im not getting GUI mode …

    i have changed “”vim /etc/inittab “” run level 3 to 5 but still im getting CLI mode

    • # yum groupinstall basic-desktop desktop-platform x11 fonts
      #yum -y groupinstall “Desktop” “Desktop Platform” “X Window System” “Fonts”
      # yum -y groupinstall “Graphical Administration Tools”
      # yum -y groupinstall “Internet Browser”
      # yum -y groupinstall “General Purpose Desktop”
      # yum -y groupinstall “Office Suite and Productivity”yum -y groupinstall “Office
      Suite and Productivity”

      install this packages after that you change /etc/inittab file and restart server desktop will com
