    The root account's credentials will be used to install packages, upgrade RPMs, and perform most system maintenance. As such, setting up a root account and password is one of the most important steps in the installation process.


    The root user (also known as the superuser) has complete access to the entire system. For this reason, you should only log in as the root user to perform system maintenance or administration.
    The Set Root Password screen prompts you to set a root password for your system. You cannot proceed to the next stage of the installation process without entering a root password.
    Enter the root password into the Root Password field. The characters you enter will be masked for security reasons. Then, type the same password into the Confirm field to ensure the password is set correctly. After you set the root password, click Next.
  10. The Partitioning Type screen displays.
    Partitioning allows you to divide your hard drive into isolated sections that each behave as their own hard drive. Partitioning is particularly useful if you run multiple operating systems. If you are unsure how to partition your system, see An Introduction to Disk Partitions in Red Hat Enterprise Linux 6 Installation Guide for more information.
    In this screen you can choose to create the default partition layout in one of four different ways, or choose to partition storage devices manually to create a custom layout.
    If you are not comfortable partitioning your system, choose one of the first four options. These options allow you to perform an automated installation without having to partition your storage devices yourself. Depending on the option you choose, you can still control what data, if any, is removed from the system. Your options are:
    • Use All Space
    • Replace Existing Linux System(s)
    • Shrink Current System
    • Use Free Space
    • Create Custom Layout
    Choose the preferred partitioning method by clicking the radio button to the left of its description in the dialog box.
    Click Next once you have made your selection. For more information on disk partitioning, see Disk Partitioning Setup in the Red Hat Enterprise Linux 6 Installation Guide.


    • It is recommended to create a separate /var partition that is large enough (50GB - 100GB) for log files, geo-replication related miscellaneous files, and other files.
    • If a user does not select Create Custom Layout, all the connected/detected disks will be used in the Volume Group for the / and /home filesystems.
  11. The Boot Loader screen displays with the default settings.
    Click Next.
  12. The Minimal Selection screen displays.
    Click Next to retain the default selections and proceed with the installation.
    • To customize your package set further, select the Customize now option and click Next. This will take you to the Customizing the Software Selection screen.
      Click Next to retain the default selections and proceed with the installation.
    • For Red Hat Gluster Storage 3.0.4 or later, if you require the Samba packages, ensure you select the RH-Gluster-Samba-Server component, in the Customizing the Software Selection screen. If you require samba active directory integration with gluster, ensure you select RH-Gluster-AD-Integration component. For NFS-Ganesha select RH-Gluster-NFS-Ganesha.
      Customize Packages

      Figure 2.2. Customize Packages

2.2.2. Installing Red Hat Gluster Storage 3.2 on Red Hat Enterprise Linux 7.3

To install Red Hat Gluster Storage 3.2 on Red Hat Enterprise Linux 7.3:
  1. Download an ISO image file for Red Hat Gluster Storage Server as described in Section 2.1, “Obtaining Red Hat Gluster Storage”
  2. In the Welcome to Red Hat Gluster Storage 3.2 screen, select the language that will be used for the rest of the installation and click Continue. This selection will also become the default for the installed system, unless changed later.


    One language is pre-selected by default on top of the list. If network access is configured at this point (for example, if you booted from a network server instead of local media), the pre-selected language will be determined based on automatic location detection using the GeoIP module.
  3. The Installation Summary screen is the central location for setting up an installation.
    Installation Summary

    Figure 2.3. Installation Summary

    Instead of directing you through consecutive screens, the Red Hat Gluster Storage 3.2 installation program on Red Hat Enterprise Linux 7.3 allows you to configure the installation in the order you choose.
    Select a menu item to configure a section of the installation. When you have completed configuring a section, or if you would like to complete that section later, click the Done button located in the upper left corner of the screen.
    Only sections marked with a warning symbol are mandatory. A note at the bottom of the screen warns you that these sections must be completed before the installation can begin. The remaining sections are optional. Beneath each section's title, the current configuration is summarized. Using this you can determine whether you need to visit the section to configure it further.
    The following list provides a brief information of each of the menu item on the Installation Summary screen:
    • Date & Time

      To configure time zone, date, and optional settings for network time, select Date & Time.

    • Language Support

      To install support for additional locales and language dialects, select Language Support.

    • Keyboard Configuration

      To add multiple keyboard layouts to your system, select Keyboard.

    • Installation Source

      To specify a file or a location to install Red Hat Enterprise Linux from, select Installation Source. On this screen, you can choose between locally available installation media, such as a DVD or an ISO file, or a network location.

    • Network & Hostname

      To configure essential networking features for your system, select Network & Hostname.


      When the Red Hat Gluster Storage 3.2 on Red Hat Enterprise Linux 7.3 installation finishes and the system boots for the first time, any network interfaces which you configured during the installation will be activated. However, the installation does not prompt you to configure network interfaces on some common installation paths - for example, when you install Red Hat Gluster Storage 3.2 on Red Hat Enterprise Linux 7.3 from a DVD to a local hard drive.
      When you install Red Hat Gluster Storage 3.2 on Red Hat Enterprise Linux 7.3 from a local installation source to a local storage device, be sure to configure at least one network interface manually if you require network access when the system boots for the first time. You will also need to set the connection to connect automatically after boot when editing the configuration.
    • Software Selection

      To specify which packages will be installed, select Software Selection. If you require the following optional Add-Ons, then select the required Add-Ons and click Done:

      • RH-Gluster-AD-Integration
      • RH-Gluster-NFS-Ganesha
      • RH-Gluster-Samba-Server
    • Installation Destination

      To select the disks and partition the storage space on which you will install Red Hat Gluster Storage, select Installation Destination. For more information on Installation Destination, see Red Hat Enterprise Linux 7 Installation Guide.

    • Kdump

      Kdump is a kernel crash dumping mechanism which, in the event of a system crash, captures information that can be invaluable in determining the cause of the crash. Use this option to select whether or not to use Kdump on the system

  4. After making the necessary configurations, click Begin Installation on the Installation Summary screen.


    Up to this point in the installation process, no lasting changes have been made on your computer. When you click Begin Installation, the installation program will allocate space on your hard drive and start to transfer Red Hat Gluster Storage into this space. Depending on the partitioning option that you chose, this process might include erasing data that already exists on your computer.
    To revise any of the choices that you made up to this point, return to the relevant section of the Installation Summary screen. To cancel installation completely, click Quit or switch off your computer.
    If you have finished customizing the installation and are certain that you want to proceed, click Begin Installation.
    After you click Begin Installation, allow the installation process to complete. If the process is interrupted, for example, by you switching off or resetting the computer, or by a power outage, you will probably not be able to use your computer until you restart and complete the Red Hat Gluster Storage installation process
  5. Once you click Begin Installation, the progress screen appears. Red Hat Gluster Storage reports the installation progress on the screen as it writes the selected packages to your system. Following is a brief description of the options on this screen:
    • Root Password

      The Root Password menu item is used to set the password for the root account. The root account is used to perform critical system management and administration tasks. The password can be configured either while the packages are being installed or afterwards, but you will not be able to complete the installation process until it has been configured.

    • User Creation

      Creating a user account is optional and can be done after installation, but it is recommended to do it on this screen. A user account is used for normal work and to access the system. Best practice suggests that you always access the system via a user account and not the root account.

  6. After the installation is completed, click Reboot to reboot your system and begin using Red Hat Gluster Storage.
