Before starting RAC installation we need to create two nodes or we can create clone
After clone or installation completed
Go to this directory
[root@six ~]# cd /etc/udev/rules.d
Copy it somewhere now I have copied it in root directory
[root@six ~]# cp 70-persistent-net.rules /root/
[root@six ~]# rm 70-persistent-net.rules
[root@six ~]# reboot
We need to change the MAC address only if you created machine via clone otherwise no need to change MAC address here I have used clone so need to change MAC address
In Network Adapter we have to change MAC address
Just here I have added in MAC any sequence we can assign
Adapter 1
Adapter 2: here we have last number with C
Adapter 3:
Here we have replace with last number 3
After this we need to open clone machine
Step 2:
Need to change hostname into the /etc/hosts directory
We can edit
[root@six ~]# vi /etc/hosts
Just for moment we need to change the hosts name
After changing the hostname we can check the hostname
[root@six ~]# hostname
First edit in /etc/hosts file with new hostname and test ping.
Second: go to /etc/sysconfig/network/ file and change host parameter.
And reboot it.
Once rebooted please check network is coming by pinging hostname.
[root@six ~]# ping six
After it we need to fixed static IP in both nodes (machines)
Go to network Connection tab we will edit network connection and set here static IP address
Node : Six Static IP Configuration
In IPv4 Setting go to with manual setting add here static ip address
eth0 : 10.0.2.14 & 255.255.255.254
Here we can see we have mention here
eth1 194.168.4.227 & Netmask 255.255.255.254
Node : Five Static IP Configuration
eth0 : 10.0.2.15 & Netmask 255.255.255.254 static IP created
eth01 : 194.168.4.228 & Netmask 255.255.255.254
Overall add static ip after that need to reboot your system
After that need to edit in /etc/hosts file
Here we need to add static ip in both node(machine)
We did mention here priv : private ip
Vip : virtual ip
before configure hosts we also need to configure network file we need to change it in both network according to network Static ip
[root@five~]$ vi /etc/sysconfig/network
[root@five~]$ cat /etc/sysconfig/network
now here we’re going to configure hosts
[root@five~]$ vi /etc/hosts
[root@five~]$ cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
# Privateeth0
192.168.1.12 five.oracle.com five
192.168.1.13 six.oracle.com six
# Publiceth1
192.168.2.14 five-priv.oracle.com five-priv
192.168.2.15 six-priv.oracle.com six-priv
# Virtual
192.168.1.16 five-vip.oracle.com five-vip
192.168.1.17 six-vip.oracle.com six-vip
# SCAN
192.168.2.11 rac-cluster.oracle.com rac-cluster
After this we need to check our created static IP is ping or not so here we’re going to check
Node 1 IP can ping node 2 IP
[root@five ~]# ping 192.168.1.12
Node 2
[root@six ~]# ping to check the network status in every network status
After it we need to login with oracle user in both node
[root@five ~]# su oracle
Need to make a directory in both node same things need to repeat in both node
[oracle@five ~]$ mkdir ~/.ssh
Assign the permission
[oracle@five ~]$ chmod 700 ~/.ssh
After assign the permission need to run
[oracle@five ~]$ /usr/bin/ssh-keygen -t rsa
Go to .ssh directory
[oracle@five ~]$ cd ~/.ssh
Run authorised cmd
[oracle@five .ssh]$ cat id_rsa.pub >> authorized_keys
[oracle@five .ssh]$ scp authorized_keys 10.0.2.14:/home/oracle/.ssh/
After this process we can access other node
[oracle@five .ssh]$ ssh six
We can watch here with the help of ssh cmd we can access other node
If we know about the different node credential
Repeat the same things in node 2 : node six
type exit will access original node
After configuration we can access both note in single terminal
after permission and unzipping we need to perform ./runInstaller
[oracle@five grid~]$ ./runInstaller
new popup Grid window will appear
