The first part, the system configuration
Modify the hostname
[root@hostname ~]vim /etc/sysconfig/network
NETWORKING=yes HOSTNAME=rac1
Modify the hosts file
[root@rac1 ~]# vim /etc/hosts
192.168.1.101 rac1 192.168.1.102 rac2 10.10.0.1 rac1-priv 10.10.0.2 rac2-priv 192.168.1.103 rac1-vip 192.168.1.104 rac2-vip 192.168.1.110 rac-scan
Disable the firewall
[root@rac1 ~]# service iptables stop
[root@rac1 ~]# chkconfig iptables off
Disable selinux
[root@rac1 ~]# vim /etc/selinux/config
SELINUX=disabled
Modify /etc/pam.d/login
[root@rac1 ~]# vim /etc/pam.d/login
session required pam_limits.so
Modify / etc / profile
[root@rac1 ~]# vim /etc/profile
if [ /$USER = "oracle" ] || [ /$USER = "grid" ]; then if [ /$SHELL = "/bin/ksh" ]; then ulimit -p 16384 ulimit -n 65536 else ulimit -u 16384 -n 65536 fi umask 022 fi
Modify /etc/csh.login
[root@rac1 ~]# vim /etc/csh.login
if ( /$USER == "oracle" || /$USER == "grid" ) then limit maxproc 16384 limit descriptors 65536 endif
Modify /etc/sysctl.conf
[root@rac1 ~]# vim /etc/sysctl.conf

CTSS configuration
using cluster Time Synchronization Service to provide synchronization service in the cluster, you need to uninstall the Network Time Protocol (NTP) and its configuration. To disable NTP service, you must stop the current ntpd service, disable the service from the initialization sequence, and remove the ntp.conf file.
[root@rac1 ~]# /sbin/service ntpd stop
[root@rac1 ~]# chkconfig ntpd off
[root@rac1 ~]# mv /etc/ntp.conf /etc/ntp.conf.original
[root@rac1 ~]# rm /var/run/ntpd.pid
Creating Users and Groups
[root@rac1 ~]# groupadd -g 501 oinstall
[root@rac1 ~]# groupadd -g 502 asmadmin
[root@rac1 ~]# groupadd -g 503 asmdba
[root@rac1 ~]# groupadd -g 504 asmoper
[root@rac1 ~]# groupadd -g 505 dba
[root@rac1 ~]# groupadd -g 506 oper
[root@rac1 ~]# useradd -m -u 1100 -g oinstall -G asmadmin,asmdba,asmoper -d /home/grid -s /bin/bash -c "Grid Infrastructure Owner" grid
[root@rac1 ~]# useradd -m -u 1101 -g oinstall -G dba,oper,asmdba -d /home/oracle -s /bin/bash -c "Oracle Software Owner" oracle
Create a directory and authorization
[root@rac1 ~]# mkdir -p /u01/app/grid
[root@rac1 ~]# mkdir -p /u01/app/11.2.0/grid
[root@rac1 ~]# chown -R grid:oinstall /u01
[root@rac1 ~]# mkdir -p /u01/app/oracle
[root@rac1 ~]# chown oracle:oinstall /u01/app/oracle
[root@rac1 ~]# chmod -R 775 /u01
