How to build an Oracle Linux 9 VM for installing Oracle Database 19c

This doc will cover how to build an Oracle Linux 9 VM for installing the Oracle database. Ref scripts in github

Build the VM

This step leverages the build_vm_ol9.sh script to build the VM

bash build_vm_ol9.sh ol9

Disable selinux

Set selinux to permissive. This will print warnings, but will not deny anything

sudo vi /etc/selinux/config
SELINUX=permissive

Disable firewall

Disable the firewall

sudo systemctl stop firewalld
sudo systemctl disable firewalld
sudo reboot

Set the ip

First get the connection name. In the below example it is “System eth0”

sudo nmcli device status
DEVICE  TYPE      STATE                   CONNECTION
eth0    ethernet  connected               System eth0
lo      loopback  connected (externally)  lo

Now we are going to give “System eth0” a static ip

sudo nmcli con mod "System eth0" ipv4.addresses 192.168.122.33/24
sudo nmcli con mod "System eth0" ipv4.gateway 192.168.122.1
sudo nmcli con mod "System eth0" ipv4.method manual
sudo nmcli con mod "System eth0" ipv4.dns "192.168.122.1"
sudo reboot

Create a disk for /u01

Now we will use qemu-img to create a 100GB disk

sudo qemu-img create -f qcow2 /vol1/vm/ol9-u01.qcow2 100G

Add the disk to the VM

sudo virsh attach-disk ol9 /vol1/vm/ol9-u01.qcow2 vdb --subdriver qcow2 --persistent

partition the disk

sudo fdisk /dev/vdb

format the disk

sudo mkfs.xfs /dev/vdb1

get uuid

sudo blkid

add a new line to /etc/fstab with uuid

sudo vi /etc/fstab
UUID=d2826585-bd79-4219-9026-acd5ea9740e3 /u01                   xfs     defaults        0 0

mount /u01

sudo systemctl daemon-reload
sudo mkdir /u01
sudo mount /u01

eject cdrom

sudo virsh change-media ol9 sda --eject

install prereqs

sudo dnf install oracle-database-preinstall-19c
