.. _storage-ubuntu-debian: Install and configure the storage nodes for Ubuntu and Debian ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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. The instructions use ``/dev/sdb`` and ``/dev/sdc``, but you can substitute different values for your particular nodes. Although Object Storage supports any file system with extended attributes (xattr), testing and benchmarking indicate the best performance and reliability on XFS. For more information on horizontally scaling your environment, see the `Deployment Guide `_. This section applies to Ubuntu 14.04 (LTS) and Debian. Prerequisites ------------- Before you install and configure the Object Storage service on the storage nodes, you must prepare the storage devices. .. note:: Perform these steps on each storage node. #. Install the supporting utility packages: .. code-block:: console # apt-get install xfsprogs rsync #. Format the ``/dev/sdb`` and ``/dev/sdc`` devices as XFS: .. code-block:: console # mkfs.xfs /dev/sdb # mkfs.xfs /dev/sdc #. Create the mount point directory structure: .. code-block:: console # mkdir -p /srv/node/sdb # mkdir -p /srv/node/sdc #. Edit the ``/etc/fstab`` file and add the following to it: .. code-block:: none /dev/sdb /srv/node/sdb xfs noatime,nodiratime,nobarrier,logbufs=8 0 2 /dev/sdc /srv/node/sdc xfs noatime,nodiratime,nobarrier,logbufs=8 0 2 #. Mount the devices: .. code-block:: console # mount /srv/node/sdb # mount /srv/node/sdc #. Create or edit the ``/etc/rsyncd.conf`` file to contain the following: .. code-block:: none 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 in production environments. 7. Edit the ``/etc/default/rsync`` file and enable the ``rsync`` service: .. code-block:: none RSYNC_ENABLE=true 8. Start the ``rsync`` service: .. code-block:: console # service rsync start Install and configure 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: .. code-block:: console # apt-get install swift swift-account swift-container swift-object 2. Obtain the accounting, container, and object 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/newton # curl -o /etc/swift/container-server.conf https://git.openstack.org/cgit/openstack/swift/plain/etc/container-server.conf-sample?h=stable/newton # curl -o /etc/swift/object-server.conf https://git.openstack.org/cgit/openstack/swift/plain/etc/object-server.conf-sample?h=stable/newton 3. .. include:: storage-include1.txt 4. .. include:: storage-include2.txt 5. .. include:: storage-include3.txt 6. Ensure proper ownership of the mount point directory structure: .. code-block:: console # chown -R swift:swift /srv/node 7. Create the ``recon`` directory and ensure proper ownership of it: .. code-block:: console # mkdir -p /var/cache/swift # chown -R root:swift /var/cache/swift # chmod -R 775 /var/cache/swift
