2.3 Selecting the Software to Install

This section describes how to use the options in the Software section of the Installation Summary screen.

Selecting the Full Installation Image

When you install Oracle Linux, you need to specify a location that contains the full installation image. To specify a location, click the Installation Source option on the Installation Summary screen to display the Installation Source screen. Figure 2.7 shows the options on this screen.


Select the location of the full installation image, as follows:

Auto-detected installation media

This option is only available if the installation program detected a local device that contains the full installation image. If you did not check the installation media when you started the installation, click Verify to check the media.

ISO file

This option is only available if the installation program detected a local hard drive that can be mounted. Select the device in the Drive list, and then click Choose an ISO to select an ISO image. Click Verify to check the media.

On the network

Select the network protocol required to access a network installation server from the list and then enter either :

  • For HTTP or HTTPS, the URL of the installation image.

    If needed, click Proxy setup and configure the details for your organization's proxy server that acts as an intermediary for Internet access.

  • For NFS and FTP, the domain name or IP address of the server and the path to the directory that contains the installation image.

    For NFS, the path can be the path to an ISO image. Enter any NFS mount options that are required.

To use a network location, ensure that the system is connected to a network (see Configuring the Host Name and Connecting to a Network) otherwise the installation program reports an error.

You can also use the + button to specify additional repositories containing software you want to install. The Server-HighAvailability and Server-Resilient Storage repositories listed contains upstream high availability packages and are not supported in Oracle Linux 7.

Click Done to save your configuration and return to the Installation Summary screen.

Selecting the Software to Install

To select the software you want to install on the system, click the Software Selection option on the Installation Summary screen to display the Software Selection screen. Figure 2.8 shows the options on this screen.


The screen is in two parts, the Base Environment on the left and the Add-Ons for Selected Environment on the right. In the Base Environment part, you select an environment that best matches what the system will be used for. In the Add-Ons part, you select the software you want to add to the selected Base Environment.

The Minimal Install base environment is the default environment. It contains only the minimum set of packages required to run Oracle Linux and does not include many administration tools that you might normally use, such as wget or unzip. This environment is the most secure environment to install and requires the least system resources to run. After the software is installed, you can install any other packages that you require.

The Server with GUI base environment is the only environment that displays a graphical desktop when the system boots. All other base environments boot into a command-line environment.

By default, the Server with GUI base environment installs the Gnome 3 desktop. If you want an alternative desktop, select KDE as an add-on.

There is no base environment or add-on for installing the Oracle Database (RDBMS). After you install Oracle Linux 7, you can use the Oracle RDBMS Server Pre-Install RPM to perform preinstallation configuration tasks for Oracle Database.

Click Done to save your configuration and return to the Installation Summary screen.
