6. Create database software directory and data file storage directory
Mkdir/u01
Mkdir/u02
Mkdir/u02/database

7, set the relevant database installation directory and file corresponding permissions
Mkdir/u01/app
Mkdir/u01/app/oracle
Mkdir/u01/app/oradata
Mkdir/u01/app/oracle/product

Chown-r oracle:oinstall/opt
Chown-r Oracle:oinstall/u01/app
Chown-r Oracle:oinstall/u02/database

chmod 777/opt
chmod 777/u01
chmod 777/u02/database/runinstaller
chmod 777/u02/database/install/.oui
chmod 777/u02/database/install/unzip

8, switch users to oracle,su-oracle. Modify the Edit environment variable Vi. bash_profile, add at the end
Umask 022
Export Oracle_base=/u01/app/oracle
Export Oracle_home= $ORACLE _base/product/11.2.0/dbhome_1

Rm-rf/u01/app
Rm-rf/u01/orainventory

Chown-r oracle:oinstall/opt
Chown-r Oracle:oinstall/u01/app
Chown-r Oracle:oinstall/u02/database

chmod 777/opt
chmod 777/u01
chmod 777/u02/database/runinstaller
chmod 777/u02/database/install/.oui
