1.The /etc/hosts file must contain the following information.
127.0.0.1       localhost.localdomain   localhost
# Public
192.168.2.101   rac1.localdomain        rac1
192.168.2.102   rac2.localdomain        rac2
#Private
192.168.0.101   rac1-priv.localdomain   rac1-priv
192.168.0.102   rac2-priv.localdomain   rac2-priv
#Virtual
192.168.2.111   rac1-vip.localdomain    rac1-vip
192.168.2.112   rac2-vip.localdomain    rac2-vip
# SCAN
192.168.2.201   rac-scan.localdomain    rac-scan
#NAS
192.168.2.101   nas1.localdomain        nas1

2.create shared disks
First we need to set up some NFS shares. In this case we will do this on the RAC1 node, but you can do the on a NAS or a third server if you have one available. On the RAC1 node create the following directories.

mkdir /shared_config
mkdir /shared_grid
mkdir /shared_home
mkdir /shared_data

Add the following lines to the /etc/exports file.

/shared_config               *(rw,sync,no_wdelay,insecure_locks,no_root_squash)
/shared_grid                 *(rw,sync,no_wdelay,insecure_locks,no_root_squash)
/shared_home                 *(rw,sync,no_wdelay,insecure_locks,no_root_squash)
/shared_data                 *(rw,sync,no_wdelay,insecure_locks,no_root_squash)

Run the following command to export the NFS shares.

chkconfig nfs on
service nfs restart

On both RAC1 and RAC2 create the directories in which the Oracle software will be installed.

mkdir -p /u01/app/11.2.0/grid
mkdir -p /u01/app/oracle/product/11.2.0/db_1
mkdir -p /u01/oradata
mkdir -p /u01/shared_config
chown -R oracle:oinstall /u01/app /u01/app/oracle /u01/oradata /u01/shared_config
chmod -R 775 /u01/app /u01/app/oracle /u01/oradata /u01/shared_config

Add the following lines to the "/etc/fstab" file.

nas1:/shared_config /u01/shared_config  nfs  rw,bg,hard,nointr,tcp,vers=3,timeo=600,rsize=32768,wsize=32768,actimeo=0,<有个空格>nolock<有个空格> 0 0
nas1:/shared_grid   /u01/app/11.2.0/grid  nfs  rw,bg,hard,nointr,tcp,vers=3,timeo=600,rsize=32768,wsize=32768,actimeo=0,<有个空格>nolock<有个空格> 0 0
nas1:/shared_home   /u01/app/oracle/product/11.2.0/db_1  nfs  rw,bg,hard,nointr,tcp,vers=3,timeo=600,rsize=32768,wsize=32768,actimeo=0,<有个空格>nolock<有个空格> 0 0
nas1:/shared_data   /u01/oradata  nfs  rw,bg,hard,nointr,tcp,vers=3,timeo=600,rsize=32768,wsize=32768,actimeo=0,<有个空格>nolock<有个空格> 0 0

Mount the NFS shares on both servers.

mount /u01/shared_config
mount /u01/app/11.2.0/grid
mount /u01/app/oracle/product/11.2.0/db_1
mount /u01/oradata

Make sure the permissions on the shared directories are correct.

chown -R oracle:oinstall /u01/shared_config
chown -R oracle:oinstall /u01/app/11.2.0/grid
chown -R oracle:oinstall /u01/app/oracle/product/11.2.0/db_1
chown -R oracle:oinstall /u01/oradata
