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.
- CentOS-6.10-i386-netinstall.iso [32-bit]
- 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.
3. Next, skip testing of the installation media to start the installation of the system.
4. Choose the language you would like to use for the installation process, and press Enter.
5. Select the keyboard layout you would like to use, and use the right arrow key select OK, and press Enter.
6. Now specify the installation method, since it is a network installation, choose URL and then press OK and hit Enter.
7. Next, configure TCP/IP for connections as shown in the screenshot below.
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
- http://mirror.liquidtelecom.com/centos/6.10/os/i386/ – [32-bit]
- http://mirror.liquidtelecom.com/centos/6.10/os/x86_64/ – [64-bit]
9. After providing the URL and clicking OK, wait for the installer to retrieve the ISO image (this may take sometime, but it should be fast with a good internet connection).
10. After successfully retrieving the ISO image, the CentOS Graphical Installer will be launched, as shown in the following screenshot. Click on Next to proceed.
11. Next, choose the type storage devices (basic or specialized) to be used for the installation and click Next.
12. Next, select the option to clear data on the storage disk by selecting Yes, discard any data and click Next.
13. Set the Hostname and click Next.
14. Set the Timezone for your location and click Next to proceed.
15. Set the root user password and click Next to continue.
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.
17. The installer will review and modify partition layout. If everything is ok, clik Next.
18. Next, apply the disk partitioning scheme created by selecting Write changes to disk and then click Next to proceed.
19. In this step, you need to choose the default set of software to be installed on your system. For the purpose of this guide, we will use Minimal and click Next. Thereafter, the installation process will be started.
20. At this point, the actual installation of the system (copying of files) to disk will now start. When it is done, click on Reboot.
21. Once you have rebooted the system, you will land at login page as shown in the screenshot below. Finally, log into your CentOS 6.10 server with the root credentials.
Congratulations! You have successfully installed CentOS 6.10 server using network installation media. If you have any questions or thoughts to share, use the feedback from below to reach us.

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.
Ranvir
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.
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
Then only one option, customize the server using CentOS DVD after installing the OS..
ok thank u

Surely laxmi, will try to provide you a guide on this, till then stay tuned.
I am getting error like this when try to install GUI mode

[line 2]: name-pkgs
Please check your iso.repo file for any spaces, errors or do a yum clean all to fix the problem.
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.
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.
Dear Ben,
Just add the ‘ifup eth0’ entry in /etc/rc.local at the bottom, your problem will solve.
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.
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..
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’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.
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.
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?
thanks.

3.However, I was able to install centos5.7 on the same machine. the difference is that I didnt burn that DVD
Can you provide some tips to help me to finish this installation?

I think you should give a try installing from USB device. Read the following article the guides you how to create bootable USB device to install Linux in systems.
Install Linux Using USB Device
sir this is what im am up to..
Requirements
– 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..
Hi Ravi,
I am a beginner to Linux, I have installed CentOS 6.4 successfully, But due to less RAM I did not get GUI installer and I completed the installation in text mode, I did not get step 20 mentioned by you, I am not sure what kind of installation I have done, now I am up and running with root login in CLI. Please let me know how to switch to GUI. Also the installer never asked me to use DVD2.iso???
How much RAM you have? the second DVD not required its optional and contains some extra packages.
Hi,

Hi Ravi,
thank you for this installation guide.
I’ve installed CentOS using DVD1, but a lot of packages are missing.
You have said that DVD2 is optional, but maybe you can tell me how to use it…
Thank you in advance!
Best regards,

You can install those missing packages using yum command from the online repositories. If you don’t connected to internet you can still install those packages from the DVD2 using yum command as shown in the below article. Please follow it.

Is internet connected to system? If yes, you need to add a DNS in /etc/resolv.conf file. For example, you should add.
Replace 8.8.8.8 with your DNS IP.

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.
i connected internet and downloaded yum packages and installed it..then what is the next command.. to get GUI mode.. Thanks.
Run init 5 on the prompt to get GUI mode.
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
Thanks

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.
Then find out what X groups available. For example, you want to install KDE, type the following groups.
Hi Ravi,
Sorry again.. i am getting below error . i created repo for packages and yum command also working but i am getting below erro
[root@HadoopCentOS ~]# yum grouplist

How can i install cent-os by commands in terminal??
waiting for help
thanks
You mean terminal access only? If yes! just select minimal packages without GUI during installation.
I have successfully installed centos 6.4 desktop on virtual box but missing ‘System tools’ from Application menu. Any idea how I can add this?
Install those packages via YUM.
Appreciate your quick response. Would you mind posting the complete command. Tried to google but could not find it.

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 192.168.0.100
i have opened the port 80 i m can local telnet it ,i use putty for installing packages for diffrent computer in lan

Can you please tell us which command you trying to execute? and getting command not found.
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.
Yes, you can install latest CentOS 6.4 using Net Install DVD. Obtain it CentOS-6.4-i386-netinstall.iso
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 ?

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?
Might you’ve selected minimal packages during installation, that’s the reason you are not getting GUI mode. About login, and don’t know, but you can reset the password by following article.
Reset Forgotten Password
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.
Add your DNS in /etc/resolv.conf file. and then do a ping.
Would I use all of these things to set up an CentOS PXE Server? I glad you have a great site.
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?
No idea man, may be issue with your LAN drivers.
use tool system-config-network becouse without this… net doesnt work ;)
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.
You must create a “/” partition to proceed further.
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 ?
No need of both ISO’s, only one is enough.
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.
Thanks.
Harry, we soon write a detailed steps for installation of PowerDNS, stay tuned of it. Thanks.
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
I’m sorted thanks:)
During installation, it asked you to fill user details and password. Enter those details to login into system.
Use
Login: root
Password: it’s what you filled during installation when wizard asked you about it.
Thanks, I just installed Minimal CD and did not know login:
Thanks Jonathan. How would I ever know that?
Only way to know the root password is to reset again. Follow the below guide to reset again root password.

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
Download first DVD is enough for you to install CentOS 6.4, the second is optional, no need of it.
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?
Thanks
Jack
Thanks Ravi.
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.
If you like to install KDE, then use:

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.
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)

No need of, everything comes with ISO that enough to run OS.
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?
Clonezilla and dump both are good, you can choose one of them.
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!!
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.
Thanks,
Suhas
Yes, you can copy into USB and then boot from thereon.
