In their dreams at night, people wander around as long as they sleep; just so, they are under the power of the snake Maya, as long as their hearts are filled with ego and duality. Through the Guru's Teachings, they come to understand and see that this world is just a dream.
Now we will create a Base
machine, I call it Base Brick Machine as I did in 11gR2 RAC install.
This machine will be used to make the SAN machine and the RAC machines. This note can also be used to install Linux on Windows 7 with Virtual machines.
Open Vmware and click
File->New Virtual Machine and you will have following screen:
Click next and you see the following:
Make sure you select “I will install the operating system later”. Otherwise when we start the machine it will start the default install of linux. I want to do custom install so select this option.
Click next and select “Linux” and Version as “Red Hat Enterprise
Linux 6 64-bit”
Location as : “C:\VM\rac12c\bbm”
Click
next and I will not change anything here and will keep one processor
Click next and I will give 2GB o this machine so that the Linux
install is quicker. Later on we will reduce its size.
Click next and select “Use bridged network card”
Click next and you will have following and make sure you
have “LSI Logic (Recommended)” selected
Click next and select “Create a new virtual disk”
Click next and make sure “SCSI (Recommended)” is selected
Click next and select Maximum disk size as “100 GB” and make
sure “Split virtual disk into multiple files” is selected.
Click next and make sure
the path provided is “C:\VM\rac12c\bbm\bbm.vmdk”
Click next and then
click finish.
You will see the following machine in the Vmware Workstation
Console.
Let’s do some modifications to it. Click “Edit virtual machine settings” and you will have the following screen.
Let’s remove “Floppy, USB Controller, Sound Card and Printer
and add some more network cards to the machine. Select “Floppy” and then click remove.
Select “USB Controller” and click remove and in the same way
select “Sound Card” and click remove and also select “Printer” and click
remove.
Finally the machine looks like following:
Now let’s add network cards.
Click “Add”. You will get the following screen and select “Network Adapter” .
Click next and select “Host-only” and make sure “Connect at power on” is selected.
Click finish. Add 2
more network cards like this and in the end you will have something like
following.
Click “OK”
Now power on the machine and by clicking green play button :
You will see the following screen on the vmware machine and
to input commands on the machine just click on the screen inside the vmware
workstation. If you want to come out of it press “ALT+CTL” together. We need to
select the very first option i.e. “Install or upgrade an existing system” ,
since its alreadt selected just hit enter.
Then you will see the following screen. Now the machine is
being prepared for Linux Install.
On the following screen just click “Next”
Click Next again.
Click Next again.
Make sure you select “Basic Storage Devices” and then click
“Next”.
Just click “Yes, discard any data”. Don’t worry it will not delete any data from Windows. It will just cleanup stuff on this particular virtual machine and where we have nothing by now.
Then on the following screen name the machine. I am naming
it “bbm.rac.meditate.com”
BBM is Base Brick Machine.
“rac.meditate.com”
AS “Meditation is better than
medication to cure all diseases in the world”
On the same screen click
“Configure Network” and the pop up opens. All network interfaces names
will be “System eth1”, “System eth2”,
“System eth3”, “System eth0”
We need to fix the ip’s and their names. Select one
interface card and the click edit.
Change name “Connection name” to “eth0” and make sure
“Connect automatically” is checked and then click tab “IPv4 Settings” and now
let’s set the ip’s. Click “Add” and then enter under address “192.168.1.115”
and under netmask “255.255.255.0” and under Gateway “192.168.1.254” (My router’s
ip address is “192.168.1.254”, if your router address is different use that
one, it can be “192.168.1.1”
In “DNS servers” also enter same router’s ip and
is “192.168.1.254”
Then apply and then click eth1 and edit and make sure “Connect automatically” is checked and then click tab “IPv4 Settings” and now let’s set the ip’s. Click “Add” and then enter under address “10.10.1.115” and under netmask “255.255.255.0” . No need to supply Gateway and DNS server.
As we did in eth1 do the same in eth2 but keep address “10.10.2.115” and under netmask “255.255.255.0” . No need to supply Gateway and DNS server.
As we did in eth1 and eth2 do the same in eth3 but keep address “10.10.3.115” and under netmask “255.255.255.0” . No need to supply Gateway and DNS server.
Click apply and you will see the following.
Click close and you will see the following, click next.
In the following screen select your time zone as I am in Pacific Time Zone in San Diego, I am selecting "America/Los Angeles" . Uncheck "system clock uses UTC option"
On the following screen make sure you select "Use All Space" option and make sure you select "Review and modify partition Layout" and click next.
Click /home and click edit and make its size as 10240 MB i.e. 10GB and click OK.
Then select swap and edit.
Make swap 5GB, i.e. 5120 MB
Now select / mount point and click edit.
Make its size 86520MB , i.e. just leave 16 or 32 MB unallocated and click OK.
Finally you will see the following and click next.
Then you will see the following screen.
Make sure you select "Basic Server" option and "CentOS" is selected and "Customise Now" radio button is also selected and click next.
I am select ing the following packages only. Nothing from applications.
From "Base Systems" just "Base", "Compatibility Libraries", "Console Internet tools", "Debugging Tools", "Directory Client", "Hardware Monitoring Utilities", "Jave Platform", "Large Systems Performance", "Network File system client", "Performance Tools", "Perl Support".
Nothing from Databases
Nothing from "Desktops"
Nothing from "High Availability"
Nothing from "Resillent Storage"
From servers install "CIFS file Server","FTP Server","NFS file server","Network Infrastructure Server",""Network Storage Server","Server Platform","System Administration Tools"
Nothing from "Virtualization"
Nothing from "web services"
Then Click next and it will take some time and Linux Install will start and wait till it asks for reboot.
You will see the following screen showing progress of install.
Now click "Reboot"
Now machine will reboot
Then login as root on the console and execute command "shutdown -h now" to shutdown the machine.
You will see the following now.
To take the backup, just copy folder "bbm" under directory C:\VM\rac12c in same directory and name it as "san12c".
After copying bbm
folder under directory "C:\VM\rac_12c" rename new folder as
"san_rac_bbm"
Open "Vmware
VIrtual Machine Configuration File" bbm under directoy
"C:\VM\rac_12c\san_rac_bbm" in your editor and
Update the following
file.
Change following:
scsi0:0.fileName =
"C:\VM\rac_12c\bbm\bbm.vmdk"
to
scsi0:0.fileName =
"C:\VM\rac_12c\san_rac_bbm\bbm.vmdk"
Now open this machine in
vmware workstation as follows:
File -> Open and
browse to the following file:
C:\VM\rac_12c\san_rac_bbm\bbm
And
click open and you will see the following screen:
Click
“Edit Virtual Machine Settings” and you will see the following screen and here
update the virtual machine name to “san_rac_bbm”
Click
Ok.
Now
start the machine by clicking “Power on this virtual machine” and then on the
following screen click “I copied it” and the machine will start now.
Once started on the following screen login as root:
Once
logged in as root vi file “/etc/sysconfig/network” to change the hostname of
the machince to “san_rac_bbm”.
In
this file update line:
HOSTNAME=bbm.rac.meditate.com
To
HOSTNAME=san_rac_bbm.rac.meditate.com
Save
the file.
Now
we will fix the networking stuff of machine so that we can connect to the
machine with putty.
To
do that execute the following command as root:
rm
–f /etc/udev/rules.d/70-persistent-net.rules
Now
vi files:
/etc/sysconfig/network-scripts/ifcfg-eth0
/etc/sysconfig/network-scripts/ifcfg-eth1
/etc/sysconfig/network-scripts/ifcfg-eth2
/etc/sysconfig/network-scripts/ifcfg-eth3
and remove the
existing HWADDR line in all the above mentioned files. Noew restart the machine
with command “reboot”
Now putty should connect,
here my settings for putty:
Download the putty.exe
from following link:
Now create a directory
under “C:” drive on windows machine “putty_logs” to store the putty_logs.
Open it by double
clicking it and do the following settings:
Login as root and try
ping to www.oracle.com and you will see its
connecting. If it not pinging, you have missed some step so you will need to
look at it.
As follows:
login as: root

Now we will install
package “oracle-rdbms-server-12cR1-preinstall” on this machine, it will create
oracle user and will groups and will modify the kernel parameters required for
install. But to install it we will have add http://public-yum.oracle.com to our yum
library to add it to yum library execue the following commands as root on putty
window.
You will get something
like this:

passwd oracle
You will have the
following update:
[root@san_rac_bbm
yum.repos.d]# passwd oracle
Changing password for
user oracle.
New password:
BAD PASSWORD: it is
based on a dictionary word
BAD PASSWORD: is too
simple
Retype new password:

Now let’s install
vmware tools on this machine as :
On vmware workstation
window, do the following:
Click VM->Install VMware Tools
Now on putty window
that we opened in the above step mount the cdrom as:
First create the cdrom
directory with the following command as root:
mkdir /cdrom
Now execue the
following command as root:
mount -t iso9660 -o ro
/dev/cdrom /cdrom
Now shift to cdrom
directory
cd /cdrom
and list the files in
it using "ls -lart"
Here is the output of
the above commands:
[root@san_rac_bbm ~]#
mkdir /cdrom
[root@san_rac_bbm ~]#
mount -t iso9660 -o ro /dev/cdrom /cdrom
[root@san_rac_bbm ~]#
cd /cdrom

follows:
shift to /tmp
directory as:
cd /tmp
Unzip it as:
tar xf

Also for this to work
we need to have firewall disabled which we already did earlier with following
command and if we have not done it execute it now:
service iptables stop
Make sure /etc/hosts
looks like above.
In file
"/etc/resolv.conf" update ip infollowing line to the ip of the local
machine:
i.e. update following
line :
from:
nameserver
192.168.1.254
to:
nameserver 192.168.1.115
MAke sure
"/etc/resolv.conf" looks as follows:
[root@san_rac_bbm

# Generated by

nameserver
192.168.1.115

Now
shutdown the machine using command “init 0” as root.
On
windows copy folder “san_rac_bbm” under directory “C:\VM\rac_12c” in same directory and name it as “san1” . I
am naming it as “san1” as while building “11gR2” cluster I named san machine as
“san”.
Now
open bbm file with extention “Vmware virtual machine configuration file” under directory “C:\VM\rac_12c\san1” in
editor and update following line :
From:
scsi0:0.fileName =
"C:\VM\rac_12c\bbm\bbm.vmdk"
to:
scsi0:0.fileName =
"C:\VM\rac_12c\san1\bbm.vmdk"
and as mentioned
earlier for machine “san_rac_bbm” , open the machine in console by opening file
“C:\VM\rac_12c\san1\bbm.vmdk” from vmware window “File à Open” . I am not placing
screenshots of this as we have already done similar thing earlier. Then click “edit virtual machine settings”
and then click “options” and here under “virtual machine name” type “san1” and click “OK”. Now power on this
virtual machine and click “I copied it”.
In console login as
root and update following line in file “/etc/sysconfig/network”
HOSTNAME=san_rac_bbm.rac.meditate.com
To
HOSTNAME=san1.rac.meditate.com
Now vi file

/etc/sysconfig/network-scripts/ifcfg-eth2
/etc/sysconfig/network-scripts/ifcfg-eth3
And update ip from “192.168.1.115”
to “192.168.1.116”
And now remove file “/etc/udev/rules.d/70-persistent-net.rules”
using following command as root:
rm –f /etc/udev/rules.d/70-persistent-net.rules
Now reboot the machine
using command “reboot” as root.
Now login through
putty and use is 192.168.1.116 to connect to it.
=======================
Now repeat the same above
steps to create machine rac20. i.e.
On
windows copy folder “san_rac_bbm” under directory “C:\VM\rac_12c” in same directory and name it as “rac20” .
Now
open bbm file with extention “Vmware virtual machine configuration file” under directory “C:\VM\rac_12c\rac20” in
editor and update following line :
From:
scsi0:0.fileName =
"C:\VM\rac_12c\bbm\bbm.vmdk"
to:
scsi0:0.fileName =
"C:\VM\rac_12c\rac20\bbm.vmdk"
and as mentioned
earlier for machine “san_rac_bbm” , open the machine in console by opening file
“C:\VM\rac_12c\rac20\bbm.vmdk” from vmware window “File à Open” . I am not placing
screenshots of this as we have already done similar thing earlier. Then click “edit virtual machine settings”
and then click “options” and here under “virtual machine name” type “rac20” and click “OK”. Now power on
this virtual machine and click “I copied it”.
In console login as
root and update following line in file “/etc/sysconfig/network”
HOSTNAME=san_rac_bbm.rac.meditate.com
To
HOSTNAME=rac20.rac.meditate.com
Now vi file
/etc/sysconfig/network-scripts/ifcfg-eth0
/etc/sysconfig/network-scripts/ifcfg-eth1
/etc/sysconfig/network-scripts/ifcfg-eth2
/etc/sysconfig/network-scripts/ifcfg-eth3
And update ip from “192.168.1.115”
to “192.168.1.117”
And now remove file “/etc/udev/rules.d/70-persistent-net.rules”
using following command as root:
rm –f /etc/udev/rules.d/70-persistent-net.rules
Now reboot the machine
using command “reboot” as root.
Now login through
putty and use is 192.168.1.117 to connect to it.
Now in next post we
will complete the setup of san1 and rac20 machine.
