How to share an Internet access from Window 10 to VirtualBox Oracle Linux 7.x Server

I am glad to share my experience here.

To share an Internet access from Windows10 to Oracle Linux7.3 which is installed in VirtualBox6.

Below are the steps required to be following in sequence.

1. VirtualBox Machine OL7.3

2. VB Network Configuration

3. After Starting OL7.3

4. Connect Wire from topLeft

5. Ifconfig After Connect Wire

6. Able to browse my website

7. Able to access VB Machine from MobaXterm (In Windows10)

Bridged Networking is used when you want your vm to be a full network citizen, i.e. to be an equal to your host machine on the network; in this mode, a virtual NIC is “bridged” to a physical NIC on your host.

The effect of this is that each VM has access to the physical network in the same way as your host. It can access any service on the network such as external DHCP services, name lookup services, and routing information just as the host does. Logically, the network looks like this:

HOL for Installing 2 Node 19c RAC in OL7.6

I am sharing my learning experience while installing 2-Node RAC Database 19.3  on Oracle Linux 7.6 64 bit deployed on Virtual Box 6.0

I faced two issues during the 19c RAC installation which i covered in this artical.

1.     Implement Platform Prerequisites

The script will setup SSH connectivity from the host racnode1 to all
the remote hosts. After the script is executed, the user can use SSH to run
commands on the remote hosts or copy files between this host racnode1
and the remote hosts without being prompted for passwords or confirmations.

NOTE 1:
As part of the setup procedure, this script will use ssh and scp to copy
files between the local host and the remote hosts. Since the script does not
store passwords, you may be prompted for the passwords during the execution of
the script whenever ssh or scp is invoked.

NOTE 2:
AS PER SSH REQUIREMENTS, THIS SCRIPT WILL SECURE THE USER HOME DIRECTORY
AND THE .ssh DIRECTORY BY REVOKING GROUP AND WORLD WRITE PRIVILEGES TO THESE
directories.

Do you want to continue and let the script make the above mentioned changes (yes/no)?

SSH setup is complete.
===================
Verifying SSH setup
===================
The script will now run the date command on the remote nodes using ssh
to verify if ssh is setup correctly. IF THE SETUP IS CORRECTLY SETUP,
THERE SHOULD BE NO OUTPUT OTHER THAN THE DATE AND SSH SHOULD NOT ASK FOR
PASSWORDS. If you see any output other than date or are prompted for the
password, ssh is not setup correctly and you will need to resolve the
issue and set up ssh again.

The possible causes for failure could be:
The server settings in /etc/ssh/sshd_config file do not allow ssh for user oracle.
The server may have disabled public key based authentication.
The client public key on the server may be outdated.
~oracle or ~oracle/.ssh on the remote host may not be owned by oracle.
User may not have passed -shared option for shared remote users or may be passing the -shared option for non-shared remote users.
If there is output in addition to the date, but no password is asked,it may be a security alert shown as part of company policy. Append the
additional text to the <OMS HOME>/sysman/prov/resources/ignoreMessages.txt file.

IF YOU SEE ANY OTHER OUTPUT BESIDES THE OUTPUT OF THE DATE COMMAND OR IF YOU ARE PROMPTED FOR A PASSWORD HERE, IT MEANS SSH SETUP HAS NOT BEEN SUCCESSFUL. Please note that being prompted for a passphrase may be OK but being prompted for a password is ERROR.
