Install Oracle Linux 7 (OEL7)

This article presents how to install Oracle Enterprise Linux 7.

I assume you have already downloaded Oracle Enterprise Linux 7 64 bit(about 4 G) and you know how to use VirtualBox 64 bit(100M). Create virtual machine with default settings for Oracle Linux 64 bit. 2GB ram (I specified 4GB for future Oracle database software installation) and 64G for disk is enough plus increase video memory to 128M and turn on acceleration 3D. Rest of options you can keep default.


1. Boot from dvd or iso file. Select first option “Install Oracle Linux 7” and press “enter” key.


2. Select your language and clink “Continue” button.


3. You should see “INSTALLATION SUMMARY” screen. Here you can change many options for your host like:

  • date and time
  • keyboard
  • language support
  • installation source
  • software selection
  • installation destination
  • network and hostname

First click “SOFTWARE SELECTION” to select extra software for this installation


4. On “SOFTWARE SELECTION” screen select “Server with GUI” for your “Base Environment”. Then select extra software you want to install by selecting it in “Add-Ons for Selected Environment”.


I recommend below list of options for later Oracle software installation and general development on Oracle Linux 7. Feel free to select extra options if you need it. When you are ready click “Done” button.

  • File and Storage Server
  • Java Platform
  • Large Systems Performance
  • Network File System Client
  • Performance Tools
  • Compatibility Libraries
  • Development Tools

5. You are back on “INSTALLATION SUMMARY” screen” so click “NETWORK CONFIGURATION” to setup network.


6. Enter Hostname in my case it’s “” set “ON” switch for Ethernet card then click “Configure” button to set details for network card.


7. In first tab check checkbox “Automatically connect to this network when it is available” to activate this network card automatically after reboot.


8. On tab “IPv4 Settings” and “IPv6 Settings” you can assign static ip address for your network card. I just use default “Automatic (DHCP)”. When you are ready click “Save..” button to save your configuration then click “Done” button.


9. You should be back on “INSTALLATION SUMMARY” screen so select “INSTALLATION DESTINATION” to configure storage.


10. Select your disk to install Oracle. You can change partitioning here. When you are happy click “Done”.


11. Just click “Begin installation” button.


12. Installation should start. Click “USER CREATION” to add extra user. The user will be used later to login to OS.


13. Enter user name, password and check checkbox “Make this user administrator”. Click “Done” button when you are ready.


14. You are back on “CONFIGURATION” screen. You need to change password for root user during installation. Click on “ROOT PASSWORD”.


15. Set password for user root and press “Done”.


16. You are back on “CONFIGURATION” screen. When installation is completed just click “Reboot” to restart machine.

21. Choose your language preferences and click “Next” button.


22. Select your keyboard preferences. You can add here more keyboards if you click “+”. Click “Next” button to continue


23. On the screen you can add your cloud accounts by clicking “Add Account” like google, facebook etc. I’m not showing details here how to do it only first screen after clicking “Add Account”.

When you are ready cllick “Next”

24. Just click “Start using Oracle Linux Everything″ button.


25. You should see introduction movies about Gnome 3 and Gnome help.

Have a fun 🙂

    • Hi Peter

      you need to change your network card from NAT(it’s default) to “Bridged adapter” in virtual box settings for your virtual machine
      then your network card in vritual box will get ip address similar to your computer eg.

      your compter
      virtual box

      then change in /etc/hosts of your virtual machine ip address assigned to your virtaul box name

      eg oel7 <-old ones oel7 <- new ones You should be able to do ping using ip address in both directions computer <=> virtual box


      • Dear Tomasz

        I found the Problem with the hostonly adapter.
        Before befining the IP-Address I hat to check by comparing the MAC-Address
        which ifcfg-en… belongs to which hostonly adapter. Than every think works fine.


  1. Hi, question:

    I downloaded OEL verdion 7.4 and have a cluster on my laptop. Just to keep up my skills. ( at works, well that is a dream, in reality, we dont have time or the machines , cpu, gb space we want. 1 TB of disk at work, forgedhhaboutit)

    But I was told that it is not really legal…. Oracle doesnt sanction that, only as a trial.


    TIA for your honest answer
