Its a good idea not to push all 14 GB software into Drive  C:\download folder instead find a drive where there is sufficient space to download it .

right click Create Folder OEL7.6 maybe in your E drive wherever you have sufficient space available. This is the location where all OEL 7.6 ISO files are Going. While we are doing OEL installation 100 GB is do have to click on next next and it will start downloading you need to have very good internet speed again it should not break. if your download fails, so it will not fail for all of the files.

click on 4GB of memory


Click on Number of  processors as  1

use ISO image file


Click on browse go to folder OEL 7.6 where our iso files are saved

Click on close 


click finish 



Now we got this pop up



We can make any changes in our configuration by clicking  on Edit virtual machine settings.

Next click on plus sign (+) first partitioning will be root partition let’s give 30 GiB and click add mount point 



Next click on plus sign (+) second partition is /data of 35 GiB then click add mount point 


Next allocate 5 GiB of SWAP memory(acts as secondary RAM when RAM is not sufficient to process Data due to heavy operations   ) and click add mount point 


Table : Recommended Swap Space Requirements 


Swap Space

1 GB – 2 GB

1.5 times the size of RAM

2 GB – 8 GB

Equal to the size of RAM

Greater than 8GB

0.75 times the size of RAM


Next boot(whenever system starts needs some memory )partition of 1 GiB then click add mount point 


Next partition is /tmp (server performs  temporary operations like copying,pasting first in /tmp directory and then send to destination   ) give space of 5 GiB

Still 4GiB space is available so we can 

We can add this up to our root partition so increase from 30 Gib to 33 Gib in our case here so modify and save 

More 1Gib space is left we can leave as it is 

Click on done 


Next click on Accept changes

——-Our oracle linux server installation is completed here ———–

Next the first thing what we have to do is take the remote of this machine using a software which which we have already install and that is called putty 

For this to happen we need to perform some networking operations as a root user 

Disable firewall to connect putty to remote server

systemctl stop firewalld

systemctl disable firewalld

First two network adapter

Click on VM –> Setting 

Add Two adapter

1) NAT – > Assign the NAT adapter -> CUSTOME with NAT

2)BRIDGE Adapter 


Click on Edit – > Virtual network Editor. NAT adapter need to be assign with following IP

Go Inside vmware and click on power button then click on setting symbol

Ens33 needs to be assign with dynamic ip and ens37 need to be assign with static ip

ens33 looks like below

ens37 setting as below

Both ethernet ens33 and ens37 need to be connected. Make sure you select automatic on option from ethernet setting

Restart server and validate all setting saved properly

Open vmware linux terminal and fire below command.

init 6


Open putty and enter the IP address and also so other setting of putty

Increase line of scrolling 


Select Change font size when maximize 


Click on ssh click on x11

Click on enable x11 forwarding 

And enter X display Location to localhost:0


Click on session 

Give name in saved session as weekend Batch

Click on save 

And click on open


Click on open





Enter the username as root and password 


The putty seems hanging 


So in order to get the prompt fast we need to disable dns service which it is looking for here 


Go to vmware vi /etc/ssh/sshd_config file and disable use DNS 

Now the prompt appears faster after disabling dns 


And you can verify the settings using linux commands 


Hope it helps
