RAC lab Part 5 – Installing OEL 7.x on VM
RAC lab Part 6 – OEL 7.x configuration for Oracle 12c GI & RAC DB installation
RAC lab Part 7 – Openfilers configuration and cloning
RAC lab Part 8 – OEL 7.x prepare storage
RAC lab Part 9 – Clone first RAC node as 2nd node and prepare config.

Oracle Enterprise Linux 7.2 installation
As you remember we had created and configured VM to host oracle rac node. The OEL7.2 iso file has been attached to the VM, we can start it now and begin the installation process.
- Start the oel72rac1n1 VM from the cli.
email@example.com ~ $ vboxmanage startvm oel72rac1n1 Waiting for VM "oel72rac1n1" to power on... VM "oel72rac1n1" has been successfully started.
- There are two options on the initial screen of OEL 7.2 installation. You can run installation or check your media and install
- Choose your preferred installation language.
- As you can see many options can be configured before you run the installation.
- Let’s start with time zone and date/time settings.
I choose minimal installation to get only the packages I really need for Oracle.
Of course minimal installation package is is not enough to fulfill requirements of GI and RAC installation – more packages are required. There will be a dedicated instruction on what else to install in the Part 6 of the series.
Choose preffered disk for the OS installation.
In my case as you remember one 50GB disk was created in Part 3 of the series. I will put LVM over it and create 16.5GB partition for swap, 3GB for /boot and over 30GB for the rest of directories. Hope this is enough to put OS and Oracle GI and DB software on it. I have limited resources at the moment, this is all I can assign to it. LVM will help me extend those disk in future when I get a brand new SDD drive and install it into my workstation.
- Confirm planned changes to the disk partitioning layout.
Skip network configuration as it causes an unwanted mess later. I will take care of the network configuration after the system has been successfully installed (Part 6).
In this step please set the hostname only (fqdn)
- Start installation and enter root password when prompted
Create named user when prompted. Make the user administrator – you will get sudo to root
Require password for the user.
- Reboot the system after the installation is over.
System is starting up..
As you can see it complains about autofs4 – will fix this in Part 6 of the series, so please don’t worry about it now.
The OS is ready now for further actions.
In the next 6th part of my RAC lab series you will learn how to configure OEL7.x operating system to fulfill Oracle 12c GI and RAC requirements. Stay tuned!!!
