To make it easier use Yum repository to install and configure pre requisites I post before how to create
local Yum repository using ISO image Read from here.
Using Yum
yum install oracle-rdbms-server-11gR2-preinstall
Manually follow the below steps:-
1- Create User On both Node
/usr/sbin/groupadd -g 501 oinstall
/usr/sbin/groupadd -g 502 dba
/usr/sbin/groupadd -g 503 oper
/usr/sbin/groupadd -g 504 asmadmin
/usr/sbin/groupadd -g 506 asmdba
/usr/sbin/groupadd -g 507 asmoper
2- Create the users that will own the Oracle software using the commands
/usr/sbin/useradd -u 501 -c "Oracle Grid Infrastructure Owner" -g oinstall -G
asmadmin,asmdba,asmoper grid
/usr/sbin/useradd -u 502 -c "Oracle RDBMS Owner" -g oinstall -G dba,oper,asmdba oracle
Set Password for Both users:-
passwd grid
passwd oracle
Note: Step #1, #2 should be even with yum.
3- Configure /etc/hosts.
4- vi /etc/sysctl.conf
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 6553600
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
/sbin/sysctl –p

5- add these lines in /etc/security/limits.conf :-
grid soft nproc 2047
grid hard nproc 16384
grid soft nofile 1024
grid hard nofile 65536
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
6- add this line in /etc/pam.d/login
session required pam_limits.so
7- Create directories :-
# mkdir -p /u01/app/oraInventory
# chown -R grid:oinstall /u01/app/oraInventory
# chmod -R 775 /u01/app/oraInventory
# mkdir -p /u01/11.2.0/grid
# chown -R grid:oinstall /u01/11.2.0/grid
# chmod -R 775 /u01/11.2.0/grid
# mkdir -p /u01/app/oracle/product/11.2.0/db_1
# chown -R oracle:oinstall /u01/app/oracle/product/11.2.0/db_1
# chmod -R 775 /u01/app/oracle/product/11.2.0/db_1
Now follow the screenshots:-
