Install Centos Linux 6

This article presents how to install Centos 6.

I assume you have already downloaded Centos Linux 6 64 bit(about 3.5 G) and you know how to use VirtualBox 64 bit(100M) which is available on OTN. Create virtual machine with default settings for Centos Linux 64 bit. 1GB ram and 32G for disk is enough to run Centos 6 64-bit. Rest of options you can keep default – however I usually increase memory for graphic card to 128M, enable 3D acceleration and set processor to 2.

1. Boot from dvd or iso file. Select first option and press “enter” key.

2. You have 2 options here “OK” or “Skip”. “OK” will start verification of your installation media. It can take quite a lot of time to verify 3.5G of data especially on DVD. I recommend to select “Skip” option. Just press tab to go to “Skip” and press enter.

3. Click on “Next”

4. Select your language and clink “Next”

5. Select your keyboard and click “Next”

6. select storage option and click “Next”

7. Click “Yes, discard any data”

8. Enter host name and click “Next”. There is interesting option here “Configure Network” to change settings of your network – click “Configure Network”.

Select “System eth0″ and click “Edit”. Then check “Connect automatically” checkbox. You can change other network settings. it’s up to you. When you are ready click “Apply”, “Close”, “Next”.

9. Select your time zone by selecting some city from your time zone and click “Next”

10. Specify root password and click “Next”

11. Select your option, check “Review and modify partitioning layout” and click “Next”

12. Just click “Next” button.

Click “Write changes to disk”

13. Accept your booting settings and click “Next”

14. Check “Customize now” and click “Next”. On next pages you can select software to install. I usually select all software for “Base System”, “Desktops”, “Applications”, “Development” and some for “Servers”. I do it to have all ready for Oracle database installation and development on Linux.

15. Boring installation …

16. Click “Reboot”

17. You should see following screen just click “Forward”

18. Another click “Forward”

20. You can add extra user here or not then click “Forward”.

21. Change date and time and click “Forward”. I always check “Synchronize data and time over the network”.

22. Just click “Finish”

23. After reboot login to machine as user root. Click “Other …”, not “Guest”

Have a fun 🙂

  1. thank you very much this helpfull article. i have a question. when i install Centos 6 in Virtualbox as a guest machine which has 2 core, the ssh command are applied slowly which are applied 1 or 1.5 second later in Windows by Putty or in LInux by Terminial Emulator by ssh client. i have searched a lot of in internet. i have applied the suggestions for sshd server but error did not fix. but by 1 core installation the Centos machine, ssh works normally without any matter. in Centos 7, there is not matter like this. in internet in some forums is said that the matter is about kernel paramaters but there is not enough explanation. What do you think about this matter? what can be cause of this problem? Thank you very much!!
