Manual ceph-iscsi Installation
|
|
==============================
|
|
|
|
**Requirements**
|
|
|
|
To complete the installation of ceph-iscsi, there are 4 steps:
|
|
|
|
1. Install common packages from your Linux distribution's software repository
|
|
2. Install Git to fetch the remaining packages directly from their Git repositories
|
|
3. Ensure a compatible kernel is used
|
|
4. Install all the components of ceph-iscsi and start associated daemons:
|
|
|
|
- tcmu-runner
|
|
- rtslib-fb
|
|
- configshell-fb
|
|
- targetcli-fb
|
|
- ceph-iscsi
|
|
|
|
|
|
1. Install Common Packages
|
|
==========================
|
|
|
|
The following packages will be used by ceph-iscsi and target tools.
|
|
They must be installed from your Linux distribution's software repository
|
|
on each machine that will be a iSCSI gateway:
|
|
|
|
- libnl3
|
|
- libkmod
|
|
- librbd1
|
|
- pyparsing
|
|
- python kmod
|
|
- python pyudev
|
|
- python gobject
|
|
- python urwid
|
|
- python pyparsing
|
|
- python rados
|
|
- python rbd
|
|
- python netifaces
|
|
- python crypto
|
|
- python requests
|
|
- python flask
|
|
- pyOpenSSL
|
|
|
|
|
|
2. Install Git
|
|
==============
|
|
|
|
In order to install all the packages needed to run iSCSI with Ceph, you need to download them directly from their repository by using Git.
|
|
On CentOS/RHEL execute:
|
|
|
|
::
|
|
|
|
> sudo yum install git
|
|
|
|
On Debian/Ubuntu execute:
|
|
|
|
::
|
|
|
|
> sudo apt install git
|
|
|
|
To know more about Git and how it works, please, visit https://git-scm.com
|
|
|
|
|
|
3. Ensure a compatible kernel is used
|
|
=====================================
|
|
|
|
Ensure you use a supported kernel that contains the required Ceph iSCSI patches:
|
|
|
|
- all Linux distribution with a kernel v4.16 or newer, or
|
|
- Red Hat Enterprise Linux or CentOS 7.5 or later (in these distributions ceph-iscsi support is backported)
|
|
|
|
If you are already using a compatible kernel, you can go to next step.
|
|
However, if you are NOT using a compatible kernel then check your distro's
|
|
documentation for specific instructions on how to build this kernel. The only
|
|
Ceph iSCSI specific requirements are that the following build options must be
|
|
enabled:
|
|
|
|
::
|
|
|
|
CONFIG_TARGET_CORE=m
|
|
CONFIG_TCM_USER2=m
|
|
CONFIG_ISCSI_TARGET=m
|
|
|
|
|
|
4. Install ceph-iscsi
|
|
========================================================
|
|
|
|
Finally, the remaining tools can be fetched directly from their Git repositories and their associated services started
|
|
|
|
|
|
tcmu-runner
|
|
-----------
|
|
|
|
Installation:
|
|
|
|
::
|
|
|
|
> git clone https://github.com/open-iscsi/tcmu-runner
|
|
> cd tcmu-runner
|
|
|
|
Run the following command to install all the needed dependencies:
|
|
|
|
::
|
|
|
|
> ./extra/install_dep.sh
|
|
|
|
Now you can build the tcmu-runner.
|
|
To do so, use the following build command:
|
|
|
|
::
|
|
|
|
> cmake -Dwith-glfs=false -Dwith-qcow=false -DSUPPORT_SYSTEMD=ON -DCMAKE_INSTALL_PREFIX=/usr
|
|
> make install
|
|
|
|
Enable and start the daemon:
|
|
|
|
::
|
|
|
|
> systemctl daemon-reload
|
|
> systemctl enable tcmu-runner
|
|
> systemctl start tcmu-runner
|
|
|
|
|
|
rtslib-fb
|
|
---------
|
|
|
|
Installation:
|
|
|
|
::
|
|
|
|
> git clone https://github.com/open-iscsi/rtslib-fb.git
|
|
> cd rtslib-fb
|
|
> python setup.py install
|
|
|
|
configshell-fb
|

--------------
|
|
|
|

|
targetcli-fb
|
|
------------
|
|
|
|

|
|
> cd targetcli-fb
|
|
> python setup.py install
|
|
> mkdir /etc/target
|
|
> mkdir /var/target
|
|
|
|
.. warning:: The ceph-iscsi tools assume they are managing all targets
|
|
on the system. If targets have been setup and are being managed by
|
|
targetcli the target service must be disabled.
|
|
|
|
ceph-iscsi
|
|

|
|
|
|
Installation:
|
|
