2.3. Installing Red Hat Gluster Storage Server on Red Hat Enterprise Linux (Layered Install)

download PDF
Layered install involves installing Red Hat Gluster Storage over Red Hat Enterprise Linux. For more information regarding supported Red Hat Enterprise Linux version for a particular Red Hat Gluster Storage release, see Section 1.7, “Red Hat Gluster Storage Support Matrix”.

Important

Virtual Data Optimizer (VDO) volumes, which are supported in Red Hat Enterprise Linux 7.5, are not currently supported in Red Hat Gluster Storage. VDO is supported only when used as part of Red Hat Hyperconverged Infrastructure for Virtualization 2.0. See Understanding VDO for more information.

Important

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.

  1. Perform a base install of Red Hat Enterprise Linux Server

    Red Hat Gluster Storage requires a kernel version of 2.6.32-431.17.1 or higher. This is available in Red Hat Enterprise Linux 6.5 and higher, and in Red Hat Enterprise Linux 7.

  2. Register the System with Subscription Manager

    Run the following command and enter your Red Hat Network user name and password to register the system with the Red Hat Network: 
    # subscription-manager register

  3. Identify Available Entitlement Pools

    Run the following commands to find entitlement pools containing the repositories required to install Red Hat Gluster Storage: 
    # subscription-manager list --available

  4. Attach Entitlement Pools to the System

    Use the pool identifiers located in the previous step to attach the Red Hat Enterprise Linux Server and Red Hat Gluster Storage entitlements to the system. Run the following command to attach the entitlements: 
    # subscription-manager attach --pool=[POOLID]
    For example: 
    # subscription-manager attach --pool=8a85f9814999f69101499c05aa706e47

  5. Enable the Required Channels

    For Red Hat Gluster Storage 3.4 on Red Hat Enterprise Linux 6.7 and later

    1. Run the following commands to enable the repositories required to install Red Hat Gluster Storage: 
      # subscription-manager repos --enable=rhel-6-server-rpms
# subscription-manager repos --enable=rhel-scalefs-for-rhel-6-server-rpms
# subscription-manager repos --enable=rhs-3-for-rhel-6-server-rpms
    2. For Red Hat Gluster Storage 3.0.4 and later, if you require Samba, then enable the following repository: 
      # subscription-manager repos --enable=rh-gluster-3-samba-for-rhel-6-server-rpms
      For more information about installing Samba, see Chapter 3, Deploying Samba on Red Hat Gluster Storage
    3. NFS-Ganesha is not supported on Red Hat Enterprise Linux 6 based installations.
    For Red Hat Gluster Storage 3.4 on Red Hat Enterprise Linux 7.x

    1. Run the following commands to enable the repositories required to install Red Hat Gluster Storage 
      # subscription-manager repos --enable=rhel-7-server-rpms
# subscription-manager repos --enable=rh-gluster-3-for-rhel-7-server-rpms
    2. For Red Hat Gluster Storage 3.0.4 and later, if you require Samba, then enable the following repository: 
      # subscription-manager repos --enable=rh-gluster-3-samba-for-rhel-7-server-rpms
      For more information about installing Samba, see Chapter 3, Deploying Samba on Red Hat Gluster Storage
    3. If you require NFS-Ganesha then enable the following repositories: 
      # subscription-manager repos --enable=rh-gluster-3-nfs-for-rhel-7-server-rpms --enable=rhel-ha-for-rhel-7-server-rpms
      For more information about installing NFS-Ganesha, see Chapter 4, Deploying NFS-Ganesha on Red Hat Gluster Storage.

  6. Verify if the Channels are Enabled

    Run the following command to verify if the channels are enabled: 
    # yum repolist

  7. Kernel Version Requirement

    Red Hat Gluster Storage requires the kernel-2.6.32-431.17.1.el6 version or higher to be used on the system. Verify the installed and running kernel versions by running the following command: 
    # rpm -q kernel
kernel-2.6.32-431.el6.x86_64
kernel-2.6.32-431.17.1.el6.x86_64
    # uname -r
2.6.32-431.17.1.el6.x86_64

  8. Update all packages

    Ensure that all packages are up to date by running the following command. 
    # yum update

    Important

    If any kernel packages are updated, reboot the system with the following command. 
    # shutdown -r now

  9. Install Red Hat Gluster Storage

    Run the following command to install Red Hat Gluster Storage: 
    # yum install redhat-storage-server
    1. For Red Hat Gluster Storage 3.0.4 and later, if you require Samba, then execute the following command to install Samba: 
      # yum groupinstall RH-Gluster-Samba-Server
    2. If you require Samba Active Directory integration with gluster, execute the following command: 
      # yum groupinstall RH-Gluster-AD-Integration
    3. To install NFS-Ganesha, see Chapter 4, Deploying NFS-Ganesha on Red Hat Gluster Storage

  10. Reboot

    Reboot the system.
