The startx command starts the graphical interface, open a terminal window, go to the folder where the database is just extracted, and run the following command [oracle @ localhost database] $. /runInstaller [4] shows how to start the oracle Installation interface. Enter the email address and password (oracle user ), to receive security updates and other information from oralce [5] Only install database software [6] in this instance select to install a single instance database [7] Select language [8] select the version to install, select "Enterprise Edition" [9] to specify Oracle Bas E and Software Location. We have set this environment variable in the profile file of the oracle user. The default value [10] is used to specify Inventory Directory, in this example, [11] is used to specify the oralce privileged user group. In this example, [12] is used as the default. Next, the oralce installer checks the installation environment. In this example, no problems are detected, the installation information is displayed as follows. Directly Finish and start installation. [13] waiting for oracle Installation [14] When the following window appears, open another terminal, log on as the root user, and execute the following command. After the execution is complete, click OK [root @ localhost ~] #/Usr/oracle/oraInventory/orainstRoot. sh
Changing permissions of/usr/oracle/oraInventory.
Adding read, write permissions for group.
Removing read, write, execute permissions for world. Changing groupname of/usr/oracle/oraInventory to oinstall.
The execution of the script is complete.

Running Oracle 11g root. sh script... The following environment variables are set:
ORACLE_OWNER = oracle
ORACLE_HOME =/usr/oracle/app/product/11.2.0/dbhome_1
[15] Now the oracle 11g R2 database has been installed. [16] disable SeLinux for other considerations. Configure FTP and above (you can also use other methods)
