This article describes the steps to install Oracle Linux 7.3 x86_64 on an Oracle VirtualBox 5.1 virtual machine.

 

  1. Creating a Virtual Machine

 Memory: 4GB

 Hard Disk: 80GB

  1. Installing Oracle Linux 7.3

  • Configure Network and Host Name
  • Configure Installation Destination

Create partitions as:

Mount point Partition Size File System
/boot /dev/sda1 1 GB xfs
swap /dev/sda2 16 GB swap
/ /dev/sda3 63 GB xfs
  • Configure Software Selection
 Minimal Install (Default)
  • Begin Installation, set root password, complete installation and reboot.

3         Post-installation of Oracle Linux

3.1         Disable Firewall

# systemctl status firewalld

# systemctl stop firewalld

# systemctl disable firewalld

# systemctl status firewalld

3.2         Network Configuration

  • Network Configuration tool
# nmtui

/etc/hosts

/etc/hostname

/etc/sysconfig/network-scripts/ifcfg-*

/etc/resolv.conf

chrony is the default package in Oracle Linux 7.

Review /etc/chrony.conf and enable NTP:

# systemctl status chronyd

# systemctl start chronyd

# systemctl enable chronyd

  1. Installing VirtualBox guest additions

To share a folder from host machine with the Oracle Linux guest, the VirtualBox Guest Additions is needed to be installed in the guest.

Navigate to VirtualBox menu:  Virtual box menu -> Devices -> Insert Guest Additions CD image

# mkdir /media/cdrom

# mount /dev/sr0 /media/cdrom

# yum install bzip2

# yum install kernel-uek-devel-`uname -r`

# export KERN_DIR=/usr/src/kernels/`uname -r`

# /media/cdrom/VBoxLinuxAdditions.run

# reboot

 

Add user to vboxsf user group, in order to use a shared folder:

# usermod -aG vboxsf oracle
