.. _share-node-install-rdo:
Install and configure a share node running Red Hat Enterprise Linux and CentOS
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This section describes how to install and configure a share node for the
Shared File Systems service. For simplicity, this configuration references one
storage node with the generic driver managing the share servers. The
generic backend manages share servers using compute, networking and block
services for provisioning shares.
Note that installation and configuration vary by distribution. This section
describes the instructions for a share node running Red Hat Enterprise Linux
or CentOS.
Install and configure components
--------------------------------
#. Install the packages:
.. code-block:: console
# dnf install openstack-manila-share python3-PyMySQL
#. Edit the ``/etc/manila/manila.conf`` file and complete the following
actions:
* In the ``[database]`` section, configure database access:
.. code-block:: ini
[database]
...
connection = mysql+pymysql://manila:MANILA_DBPASS@controller/manila
Replace ``MANILA_DBPASS`` with the password you chose for
the Shared File Systems database.
.. include:: common/share-node-common-configuration.rst
Two driver modes
----------------
.. include:: common/share-node-share-server-modes.rst
Choose one of the following options to configure the share driver:
.. include:: common/dhss-false-mode-intro.rst
Prerequisites
-------------
.. note::
Perform these steps on the storage node.
#. Install the supporting utility packages:
* Install LVM and NFS server packages:
.. code-block:: console
# dnf install lvm2 nfs-utils nfs4-acl-tools portmap targetcli
* Start the LVM metadata service and configure it to start when the
system boots:
.. code-block:: console
# systemctl enable lvm2-lvmetad.service target.service
# systemctl start lvm2-lvmetad.service target.service
.. include:: common/dhss-false-mode-configuration.rst
.. include:: common/dhss-true-mode-intro.rst
Prerequisites
-------------
Before you proceed, verify operation of the Compute, Networking, and Block
Storage services. This options requires implementation of Networking option 2
and requires installation of some Networking service components on the storage
node.
* Install the Networking service components:
.. code-block:: console
# dnf install openstack-neutron openstack-neutron-linuxbridge ebtables
.. include:: common/dhss-true-mode-configuration.rst
Finalize installation
---------------------
#. Prepare manila-share as start/stop service. Start the Shared File Systems
service including its dependencies and configure them to start when the
system boots:
.. code-block:: console
# systemctl enable openstack-manila-share.service
# systemctl start openstack-manila-share.service
