Extract the database image files and use the runInstaller command to start the installation. At any time during installation, if you have a question about what you are being asked to do, click Help.

1. Log in as the Oracle installation owner user account (oracle) that you want to own the software binaries.
2. Download the Oracle Database installation image files (db_home.zip) to a directory of your choice. For example, you can download the image files to the /tmp directory.
3. Create the Oracle home directory and extract the image files that you have downloaded in to this Oracle home directory. For example:

   $ mkdir -p /u01/app/oracle/product/18.0.0/dbhome_1
   $ chown oracle:oinstall /u01/app/oracle/product/18.0.0/dbhome_1
   $ cd /u01/app/oracle/product/18.0.0/dbhome_1
   $ unzip -q /tmp/db_home.zip

   Note:

   Oracle recommends that the Oracle home directory path you create is in compliance with the Oracle Optimal Flexible Architecture recommendations. Also, unzip the installation image files only in this Oracle home directory that you created.
4. From the Oracle home directory, run the runInstaller command to start the Oracle Database Setup Wizard.

   $ cd /u01/app/oracle/product/18.0.0/dbhome_1
   $ ./runInstaller
   

5. In the Select Configuration Option screen, select Create and configure a single instance database.
6. Select your installation type.

   Installation screens vary depending on the installation option you select. Respond to the configuration prompts as needed.
