-Configuring the iSCSI Target using the Command Line Interface
-=============================================================
-
-The Ceph iSCSI gateway is the iSCSI target node and also a Ceph client
-node. The Ceph iSCSI gateway can be a standalone node or be colocated on
-a Ceph Object Store Disk (OSD) node. Completing the following steps will
-install, and configure the Ceph iSCSI gateway for basic operation.
-
-**Requirements:**
-
-- A running Ceph Luminous or later storage cluster
-
-- RHEL/CentOS 7.4; or Linux kernel v4.14 or newer
-
-- The following packages must be installed from your Linux distribution's software repository:
-
- - ``targetcli-2.1.fb47`` or newer package
-
- - ``python-rtslib-2.1.fb64`` or newer package
-
- - ``tcmu-runner-1.3.0`` or newer package
-
- - ``ceph-iscsi-config-2.3`` or newer package
-
- - ``ceph-iscsi-cli-2.5`` or newer package
-
- .. important::
- If previous versions of these packages exist, then they must
- be removed first before installing the newer versions.
-
-Do the following steps on the Ceph iSCSI gateway node before proceeding
-to the *Installing* section:
-
-#. If the Ceph iSCSI gateway is not colocated on an OSD node, then copy
- the Ceph configuration files, located in ``/etc/ceph/``, from a
- running Ceph node in the storage cluster to the iSCSI Gateway node.
- The Ceph configuration files must exist on the iSCSI gateway node
- under ``/etc/ceph/``.
-
-#. Install and configure the `Ceph Command-line
- Interface <http://docs.ceph.com/docs/master/start/quick-rbd/#install-ceph>`_
-
-#. If needed, open TCP ports 3260 and 5000 on the firewall.
-
-#. Create a new or use an existing RADOS Block Device (RBD).
-
-**Installing:**
-
-#. As ``root``, on all iSCSI gateway nodes, install the
- ``ceph-iscsi-cli`` package:
-
- ::
-
- # yum install ceph-iscsi-cli
-
-#. As ``root``, on all iSCSI gateway nodes, install the ``tcmu-runner``
- package:
-
- ::
-
- # yum install tcmu-runner
-
-#. As ``root``, on a iSCSI gateway node, create a file named
- ``iscsi-gateway.cfg`` in the ``/etc/ceph/`` directory:
-
- ::
-
- # touch /etc/ceph/iscsi-gateway.cfg
-
- #. Edit the ``iscsi-gateway.cfg`` file and add the following lines:
-
- ::
-
- [config]
- # Name of the Ceph storage cluster. A suitable Ceph configuration file allowing
- # access to the Ceph storage cluster from the gateway node is required, if not
- # colocated on an OSD node.
- cluster_name = ceph
-
- # Place a copy of the ceph cluster's admin keyring in the gateway's /etc/ceph
- # drectory and reference the filename here
- gateway_keyring = ceph.client.admin.keyring
-
-
- # API settings.
- # The API supports a number of options that allow you to tailor it to your
- # local environment. If you want to run the API under https, you will need to
- # create cert/key files that are compatible for each iSCSI gateway node, that is
- # not locked to a specific node. SSL cert and key files *must* be called
- # 'iscsi-gateway.crt' and 'iscsi-gateway.key' and placed in the '/etc/ceph/' directory
- # on *each* gateway node. With the SSL files in place, you can use 'api_secure = true'
- # to switch to https mode.
-
- # To support the API, the bear minimum settings are:
- api_secure = false
-
- # Additional API configuration options are as follows, defaults shown.
- # api_user = admin
- # api_password = admin
- # api_port = 5001
- # trusted_ip_list = 192.168.0.10,192.168.0.11
-
- .. important::
- The ``iscsi-gateway.cfg`` file must be identical on all iSCSI gateway nodes.
-
- #. As ``root``, copy the ``iscsi-gateway.cfg`` file to all iSCSI
- gateway nodes.
-
-#. As ``root``, on all iSCSI gateway nodes, enable and start the API
- service:
-
- ::
-
- # systemctl enable rbd-target-api
- # systemctl start rbd-target-api
-
-**Configuring:**
-
-#. As ``root``, on a iSCSI gateway node, start the iSCSI gateway
- command-line interface:
-
- ::
-
- # gwcli
-
-#. Creating the iSCSI gateways:
-
- ::
-
- >/iscsi-target create iqn.2003-01.com.redhat.iscsi-gw:<target_name>
- > goto gateways
- > create <iscsi_gw_name> <IP_addr_of_gw>
- > create <iscsi_gw_name> <IP_addr_of_gw>
-
-#. Adding a RADOS Block Device (RBD):
-
- ::
-
- > cd /iscsi-target/iqn.2003-01.com.redhat.iscsi-gw:<target_name>/disks/
- >/disks/ create pool=<pool_name> image=<image_name> size=<image_size>m|g|t
-
-#. Creating a client:
-
- ::
-
- > goto hosts
- > create iqn.1994-05.com.redhat:<client_name>
- > auth chap=<user_name>/<password> | nochap
-
-
- .. warning::
- CHAP must always be configured. Without CHAP, the target will
- reject any login requests.
-
-#. Adding disks to a client:
-
- ::
-
- >/iscsi-target..eph-igw/hosts> cd iqn.1994-05.com.redhat:<client_name>
- > disk add <pool_name>.<image_name>
-
-The next step is to configure the iSCSI initiators.
