Fedora 25 Installation for Oracle Database 12c Release 1

This guide will walk you through the steps to perform basic installation of Fedora 25 and prepare it for oracle database 12c release 1 installation.

STEP1 - Downloading and Installing Fedora 25

To begin with the installation, you need to download Fedora 25 and boot from the Fedora ISO image or USB/DVD. Pick the "Install Fedora 25" option and Press Enter key.

Select the appropriate language then select the "Set keyboard to default layout for selected language" option, and click on "Continue".

On the following screen, you are presented with the "Installation Summary". You must complete any marked items before you can continue with the installation. Depending on your requirements, you may also want to alter the default settings by clicking on the relevant links.

Click on the "Installation Destination" link.

If you are Ok to use automatic partitioning of the whole disk, click the "Done" button to return to the previous screen. If you want to modify the partitioning configuration, select the "I will configure partitioning" option and click the "Done" button to work through the manual partitioning .

Once you have done alterations to the default configuration, click the "Begin Installation" button.

Click the "Root Password" link.

Enter the root password and click the "Done".

Click the "User Creation" link.

Enter the user details and select the "Make this user administrator" option, then click the "Done".

When you are prompted, click the "Finish Configuration" button.

Wait for the installation to complete. When prompted, click the "Reboot" button.

Login as the "root" user when prompted.

If you want a GUI desktop, issue the following commands from the console to install the desktop packages and reboot.

# dnf update -y
# dnf groupinstall "MATE Desktop" -y
# systemctl set-default graphical.target
# reboot

Select the user you wish to log in as and enter the password, then click the "Log In" button.

You are now presented with the desktop screen.

STEP2 - Network Configuration

If you are using DHCP to configure your network settings, then ignore the following network configuration screens, otherwise right-click on the network icon in the top toolbar and select the "Edit connections" option. 
Select the network of interest and click the "Edit" button.

Click the "IPv4" section, select the "Manual" method and enter the appropriate IP address and subnet mask, default gateway and primary DNS, then click the "Save" button.

Close the "Network Connections" dialog.


If the OS is to be used for an Oracle installation, it is easier if Secure Linux (SELinux) is disabled or switched to permissive. To accomplish this, edit the "/etc/selinux/config" file, making sure the SELINUX flag is set as follows.


If SELinux is configured after installation, the server will need a reboot for the change to take effect.


If the OS is to be used for an Oracle installation, it is easier if the firewall is disabled. This can be done by issuing the following commands from a terminal window as the "root" user.

# systemctl stop firewalld
# systemctl disable firewalld

You can install and configure it later if you wish.


Make sure the SSH daemon is started using the following commands.

# systemctl start sshd.service
# systemctl enable sshd.service


We have demonstrated basic installation and configuration of Fedora 25 Linux specifically for oracle database installation. I hope this guide was useful to prepare your Fedora 25 machine for database deployment on it.
