Install and configure the controller node
=========================================
This section describes how to install and configure the proxy service that
handles requests for the account, container, and object services operating
on the storage nodes. For simplicity, this guide installs and configures
the proxy service on the controller node. However, you can run the proxy
service on any node with network connectivity to the storage nodes.
Additionally, you can install and configure the proxy service on multiple
nodes to increase performance and redundancy. For more information, see the
`Deployment Guide <http://docs.openstack.org/developer/swift/deployment_guide.html>`__.
To configure prerequisites
~~~~~~~~~~~~~~~~~~~~~~~~~~
The proxy service relies on an authentication and authorization mechanism such
as the Identity service. However, unlike other services, it also offers an
internal mechanism that allows it to operate without any other OpenStack
services. However, for simplicity, this guide references the Identity service
in :doc:`keystone`. Before you configure the Object Storage service, you must
create service credentials and an API endpoint.
.. note::
The Object Storage service does not use a SQL database on the controller
node. Instead, it uses distributed SQLite databases on each storage node.
#. Source the ``admin`` credentials to gain access to admin-only CLI commands:
.. code-block:: console
$ source admin-openrc.sh
#. To create the Identity service credentials, complete these steps:
* Create the ``swift`` user:
.. code-block:: console
$ openstack user create --password-prompt swift
User Password:
Repeat User Password:
+----------+----------------------------------+
| Field | Value |
+----------+----------------------------------+
| email | None |
| enabled | True |
| id | d535e5cbd2b74ac7bfb97db9cced3ed6 |
| name | swift |
| username | swift |
+----------+----------------------------------+
* Add the ``admin`` role to the ``swift`` user:
.. code-block:: console
$ openstack role add --project service --user swift admin
+-------+----------------------------------+
| Field | Value |
+-------+----------------------------------+
| id | cd2cb9a39e874ea69e5d4b896eb16128 |
| name | admin |
+-------+----------------------------------+
* Create the ``swift`` service entity:
.. code-block:: console
$ openstack service create --name swift \
--description "OpenStack Object Storage" object-store
+-------------+----------------------------------+
| Field | Value |
+-------------+----------------------------------+

| id | 75ef509da2c340499d454ae96a2c5c34 |
| name | swift |
| type | object-store |
+-------------+----------------------------------+
#. Create the Object Storage service API endpoint:
.. code-block:: console
$ openstack endpoint create \
--publicurl 'http://controller:8080/v1/AUTH_%(tenant_id)s' \
--internalurl 'http://controller:8080/v1/AUTH_%(tenant_id)s' \
--adminurl http://controller:8080 \

====================
Create initial rings
====================
Before starting the Object Storage services, you must create the initial
account, container, and object rings. The ring builder creates configuration
files that each node uses to determine and deploy the storage architecture.
For simplicity, this guide uses one region and zone with 2^10 (1024) maximum
partitions, 3 replicas of each object, and 1 hour minimum time between moving
a partition more than once. For Object Storage, a partition indicates a
directory on a storage device rather than a conventional partition table.
For more information, see the
`Deployment Guide <http://docs.openstack.org/developer/swift/deployment_guide.html>`__.
Account ring
~~~~~~~~~~~~
The account server uses the account ring to maintain lists of containers.
To create the ring perform the following steps on the controller node.
#. Change to the :file:`/etc/swift` directory.
#. Create the base :file:`account.builder` file:
.. code-block:: console
# swift-ring-builder account.builder create 10 3 1
.. note::
This command provides no output.
#. Add each storage node to the ring:
.. code-block:: console
# swift-ring-builder account.builder \
add --region 1 --zone 1 --ip STORAGE_NODE_MANAGEMENT_INTERFACE_IP_ADDRESS --port 6002 \
--device DEVICE_NAME --weight DEVICE_WEIGHT
Replace ``STORAGE_NODE_MANAGEMENT_INTERFACE_IP_ADDRESS`` with the IP address
of the management network on the storage node. Replace ``DEVICE_NAME`` with a
storage device name on the same storage node. For example, using the first
storage node in :doc:`swift-storage-node` with the :file:`/dev/sdb1` storage
device and weight of 100:
.. code-block:: console
# swift-ring-builder account.builder add \
--region 1 --zone 1 --ip 10.0.0.51 --port 6002 --device sdb1 --weight 100
Repeat this command for each storage device on each storage node. In the
example architecture, use the command in four variations:
.. code-block:: console
# swift-ring-builder account.builder add \
--region 1 --zone 1 --ip 10.0.0.51 --port 6002 --device sdb1 --weight 100
Device d0r1z1-10.0.0.51:6002R10.0.0.51:6002/sdb1_"" with 100.0 weight got id 0
# swift-ring-builder account.builder add \
--region 1 --zone 2 --ip 10.0.0.51 --port 6002 --device sdc1 --weight 100
Device d1r1z2-10.0.0.51:6002R10.0.0.51:6002/sdc1_"" with 100.0 weight got id 1
# swift-ring-builder account.builder add \
--region 1 --zone 3 --ip 10.0.0.52 --port 6002 --device sdb1 --weight 100
Device d2r1z3-10.0.0.52:6002R10.0.0.52:6002/sdb1_"" with 100.0 weight got id 2

Container ring
~~~~~~~~~~~~~~
The container server uses the container ring to maintain lists of objects.
However, it does not track object locations.
To create the ring perform the following steps on the controller node.
#. Change to the :file:`/etc/swift` directory.
#. Create the base :file:`container.builder` file:
.. code-block:: console
# swift-ring-builder container.builder create 10 3 1
.. note::
This command provides no output.
#. Add each storage node to the ring:
.. code-block:: console
# swift-ring-builder container.builder \
add --region 1 --zone 1 --ip STORAGE_NODE_MANAGEMENT_INTERFACE_IP_ADDRESS --port 6001 \
--device DEVICE_NAME --weight DEVICE_WEIGHT
Replace ``STORAGE_NODE_MANAGEMENT_INTERFACE_IP_ADDRESS`` with the IP address
of the management network on the storage node. Replace ``DEVICE_NAME`` with a
storage device name on the same storage node. For example, using the first
storage node in :doc:`swift-storage-node` with the :file:`/dev/sdb1`
storage device and weight of 100:
.. code-block:: console
# swift-ring-builder container.builder add \
--region 1 --zone 1 --ip 10.0.0.51 --port 6001 --device sdb1 --weight 100
Repeat this command for each storage device on each storage node. In the
example architecture, use the command in four variations:
.. code-block:: console
# swift-ring-builder container.builder add \
--region 1 --zone 1 --ip 10.0.0.51 --port 6001 --device sdb1 --weight 100
Device d0r1z1-10.0.0.51:6001R10.0.0.51:6001/sdb1_"" with 100.0 weight got id 0

Object ring
~~~~~~~~~~~
The object server uses the object ring to maintain lists of object locations
on local devices.
To create the ring perform the following steps on the controller node.
#. Change to the :file:`/etc/swift` directory.
#. Create the base :file:`object.builder` file:
.. code-block:: console
# swift-ring-builder object.builder create 10 3 1
.. note::
This command provides no output.
#. Add each storage node to the ring:
.. code-block:: console
# swift-ring-builder object.builder \
add --region 1 --zone 1 --ip STORAGE_NODE_MANAGEMENT_INTERFACE_IP_ADDRESS --port 6000 \
--device DEVICE_NAME --weight DEVICE_WEIGHT
Replace ``STORAGE_NODE_MANAGEMENT_INTERFACE_IP_ADDRESS`` with the IP address
of the management network on the storage node. Replace ``DEVICE_NAME`` with
a storage device name on the same storage node. For example, using the first
storage node in :doc:`swift-storage-node` with the :file:`/dev/sdb1` storage
device and weight of 100:
.. code-block:: console
# swift-ring-builder object.builder add r1z1-10.0.0.51:6000/sdb1 100
Repeat this command for each storage device on each storage node. In the
example architecture, use the command in four variations:
.. code-block:: console
# swift-ring-builder object.builder add \
--region 1 --zone 1 --ip 10.0.0.51 --port 6000 --device sdb1 --weight 100
Device d0r1z1-10.0.0.51:6000R10.0.0.51:6000/sdb1_"" with 100.0 weight got id 0
# swift-ring-builder object.builder add \

=======================================
Install and configure the storage nodes
=======================================
This section describes how to install and configure storage nodes
that operate the account, container, and object services. For
simplicity, this configuration references two storage nodes, each
containing two empty local block storage devices. Each of the
devices, :file:`/dev/sdb` and :file:`/dev/sdc`, must contain a
suitable partition table with one partition occupying the entire
device. Although the Object Storage service supports any file system
with :term:`extended attributes (xattr)`, testing and benchmarking
indicate the best performance and reliability on :term:`XFS`. For
more information on horizontally scaling your environment, see the
`Deployment Guide <http://docs.openstack.org/developer/swift/deployment_guide.html>`_.
To configure prerequisites
~~~~~~~~~~~~~~~~~~~~~~~~~~
You must configure each storage node before you install and configure
the Object Storage service on it. Similar to the controller node, each
storage node contains one network interface on the :term:`management network`.
Optionally, each storage node can contain a second network interface on
a separate network for replication. For more information, see
:doc:`basic_environment`.
#. Configure unique items on the first storage node:
Configure the management interface:
* IP address: ``10.0.0.51``
* Network mask: ``255.255.255.0`` (or ``/24``)
* Default gateway: ``10.0.0.1``
Set the hostname of the node to ``object1``.
#. Configure unique items on the second storage node:
Configure the management interface:
* IP address: ``10.0.0.52``
* Network mask: ``255.255.255.0`` (or ``/24``)
* Default gateway: ``10.0.0.1``
Set the hostname of the node to ``object2``.
#. Configure shared items on both storage nodes:
* Copy the contents of the :file:`/etc/hosts` file from the controller
node and add the following to it:
.. code-block:: ini
:linenos:
# object1
10.0.0.51 object1
# object2
10.0.0.52 object2
Also add this content to the :file:`/etc/hosts` file on all other
nodes in your environment.
* Install and configure :term:`NTP <Network Time Protocol (NTP)>` using
the instructions in :doc:`basics-ntp`.
* Install the supporting utility packages:
.. only:: ubuntu or debian
.. code-block:: console
# apt-get install xfsprogs rsync
.. only:: rdo
.. code-block:: console
# yum install xfsprogs rsync
.. only:: obs
.. code-block:: console
# zypper install xfsprogs rsync
* Format the :file:`/dev/sdb1` and :file:`/dev/sdc1` partitions as XFS:
.. code-block:: console
# mkfs.xfs /dev/sdb1
# mkfs.xfs /dev/sdc1
* Create the mount point directory structure:
.. code-block:: console
# mkdir -p /srv/node/sdb1
# mkdir -p /srv/node/sdc1
* Edit the :file:`etc/fstab` file and add the following to it:
.. code-block:: ini
:linenos:
/dev/sdb1 /srv/node/sdb1 xfs noatime,nodiratime,nobarrier,logbufs=8 0 2
/dev/sdc1 /srv/node/sdc1 xfs noatime,nodiratime,nobarrier,logbufs=8 0 2
* Mount the devices:
.. code-block:: console
# mount /srv/node/sdb1
# mount /srv/node/sdc1
#. Edit the :file:`/etc/rsyncd.conf` file and add the following to it:
.. code-block:: ini
:linenos:
uid = swift
gid = swift
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
address = MANAGEMENT_INTERFACE_IP_ADDRESS
[account]
max connections = 2
path = /srv/node/
read only = false
lock file = /var/lock/account.lock
[container]
max connections = 2
path = /srv/node/
read only = false
lock file = /var/lock/container.lock
[object]
max connections = 2
path = /srv/node/
read only = false
lock file = /var/lock/object.lock
Replace ``MANAGEMENT_INTERFACE_IP_ADDRESS`` with the IP address of the
management network on the storage node.
.. note::
The ``rsync`` service requires no authentication, so consider running
it on a private network.
.. only:: ubuntu or debian
5. Edit the :file:`/etc/default/rsync` file and enable the ``rsync``
service:
.. code-block:: ini
:linenos:
RSYNC_ENABLE=true
6. Start the ``rsync`` service:
.. code-block:: console
# service rsync start
.. only:: obs or rdo
5. Start the ``rsyncd`` service and configure it to start when the
system boots:
.. code-block:: console
# systemctl enable rsyncd.service
# systemctl start rsyncd.service
Install and configure storage node components
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. note::
Default configuration files vary by distribution. You might need
to add these sections and options rather than modifying existing
sections and options. Also, an ellipsis (...) in the configuration
snippets indicates potential default configuration options that you
should retain.
.. note::
Perform these steps on each storage node.
#. Install the packages:
.. only:: ubuntu or debian
.. code-block:: console
# apt-get install swift swift-account swift-container swift-object
.. only:: rdo
.. code-block:: console
# yum install openstack-swift-account openstack-swift-container \
openstack-swift-object
.. only:: obs
.. code-block:: console
# zypper install openstack-swift-account \
openstack-swift-container openstack-swift-object python-xml
.. only:: ubuntu or rdo or debian
2. Obtain the accounting, container, object, container-reconciler, and
object-expirer service configuration files from the Object Storage
source repository:
.. code-block:: console
# curl -o /etc/swift/account-server.conf \
https://git.openstack.org/cgit/openstack/swift/plain/etc/account-server.conf-sample?h=stable/kilo
# curl -o /etc/swift/container-server.conf \
https://git.openstack.org/cgit/openstack/swift/plain/etc/container-server.conf-sample?h=stable/kilo
# curl -o /etc/swift/object-server.conf \
https://git.openstack.org/cgit/openstack/swift/plain/etc/object-server.conf-sample?h=stable/kilo
# curl -o /etc/swift/container-reconciler.conf \
https://git.openstack.org/cgit/openstack/swift/plain/etc/container-reconciler.conf-sample?h=stable/kilo
# curl -o /etc/swift/object-expirer.conf \
https://git.openstack.org/cgit/openstack/swift/plain/etc/object-expirer.conf-sample?h=stable/kilo
3. .. include:: swift-storage-node-include1.txt
4. .. include:: swift-storage-node-include2.txt
5. .. include:: swift-storage-node-include3.txt
6. Ensure proper ownership of the mount point directory structure:
.. code-block:: console
# chown -R swift:swift /srv/node
7. Create the :file:`recon` directory and ensure proper ownership of it:
.. code-block:: console
# mkdir -p /var/cache/swift
# chown -R swift:swift /var/cache/swift
.. only:: obs
2. .. include:: swift-storage-node-include1.txt
3. .. include:: swift-storage-node-include2.txt
4. .. include:: swift-storage-node-include3.txt
5. Ensure proper ownership of the mount point directory structure:
.. code-block:: console
# chown -R swift:swift /srv/node
6. Create the :file:`recon` directory and ensure proper ownership of it:
.. code-block:: console
# mkdir -p /var/cache/swift
# chown -R swift:swift /var/cache/swift
