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:-


Enter LISTENER NAME and Cluster Name


Configure SSH between nodes the installation will fail without it.


Choose Which IP for Public and Private


After the above steps the RAC will be installed successfully don’t ignore any error message.

Now After Grid Installation, The ASM Configuration and Create DATA and FRA Disk like the

below.


DATABASE


After the above steps is done It’s Time to create Database.
