Software Requirements
- `simplejson Python module <http://code.google.com/p/simplejson/>`_
- `pyparsing Python module <http://pyparsing.wikispaces.com/>`_, version
1.4.6 or above
-- `pyinotify Python module <http://trac.dbzteam.org/pyinotify/>`_
+- `pyinotify Python module <https://github.com/seb-m/pyinotify>`_
- `PycURL Python module <http://pycurl.sourceforge.net/>`_
-- `ctypes Python module
- <http://starship.python.net/crew/theller/ctypes/>`_, if running on
- python 2.4 (optional, used for node daemon memory locking)
- `socat <http://www.dest-unreach.org/socat/>`_, see :ref:`note
<socat-note>` below
-- `Paramiko <http://www.lag.net/paramiko/>`_, if you want automated SSH
- setup; optional otherwise but manual setup of the nodes required
+- `Paramiko <http://www.lag.net/paramiko/>`_, if you want to use
+ ``ganeti-listrunner``
- `affinity Python module <http://pypi.python.org/pypi/affinity/0.1.0>`_,
optional python package for supporting CPU pinning under KVM
-- `ElementTree Python module <http://effbot.org/zone/element-index.htm>`_,
- if running on python 2.4 (optional, used by the ``ovfconverter`` tool)
- `qemu-img <http://qemu.org/>`_, if you want to use ``ovfconverter``
- `fping <http://fping.sourceforge.net/>`_

These programs are supplied as part of most Linux distributions, so
usually they can be installed via the standard package manager. Also
$ apt-get install lvm2 ssh bridge-utils iproute iputils-arping \
ndisc6 python python-pyopenssl openssl \
- python-pyparsing python-simplejson \
- python-pyinotify python-pycurl socat fping
+ python-pyparsing python-simplejson python-bitarray \
+ python-pyinotify python-pycurl python-ipaddr socat fping
+
+If bitarray is missing it can be installed from easy-install::
+
+ $ easy_install bitarray
+
+Or on newer distributions (eg. Debian Wheezy) the above becomes::
+
+ $ apt-get install lvm2 ssh bridge-utils iproute iputils-arping \
+ ndisc6 python python-openssl openssl \
+ python-pyparsing python-simplejson python-bitarray \
+ python-pyinotify python-pycurl python-ipaddr socat fping
Note that this does not install optional packages::
Haskell requirements
~~~~~~~~~~~~~~~~~~~~
-If you want to enable the `htools` component, which is recommended on
-bigger deployments (this give you automatic instance placement, cluster
-balancing, etc.), then you need to have a Haskell compiler installed on
-your build machine (but this is not required on the machines which are
-just going to run Ganeti). More specifically:
+Starting with Ganeti 2.7, the Haskell GHC compiler and a few base
+libraries are required in order to build Ganeti (but not to run and
+deploy Ganeti on production machines). More specifically:
- `GHC <http://www.haskell.org/ghc/>`_ version 6.12 or higher
- or even better, `The Haskell Platform
network library
- `parallel <http://hackage.haskell.org/package/parallel>`_, a parallel
programming library (note: tested with up to version 3.x)
-- `curl <http://hackage.haskell.org/package/curl>`_, bindings for the
- curl library, only needed if you want these tools to connect to remote
- clusters (as opposed to the local one)
- `bytestring <http://hackage.haskell.org/package/bytestring>`_ and
`utf8-string <http://hackage.haskell.org/package/utf8-string>`_
libraries; these usually come with the GHC compiler
-- `regex-pcre <http://hackage.haskell.org/package/regex-pcre>`_,
- bindings for the ``pcre`` library
+- `deepseq <http://hackage.haskell.org/package/deepseq>`_
Some of these are also available as package in Debian/Ubuntu::
$ apt-get install ghc6 libghc6-json-dev libghc6-network-dev \
- libghc6-parallel-dev libghc6-curl-dev
-
-Or in Fedora running::
+ libghc6-parallel-dev libghc6-deepseq-dev
- $ yum install ghc ghc-json-devel ghc-network-devel ghc-parallel-devel
+Or in newer versions of these distributions (using GHC 7.x)::
-The most recent Fedora doesn't provide ``ghc-curl``. So this needs to be
-installed using ``cabal`` or alternatively htools can be build without
-curl support.
+ $ apt-get install ghc libghc-json-dev libghc-network-dev \
+ libghc-parallel-dev libghc-deepseq-dev \
+ libghc-utf8-string-dev
-Note that more recent version have switched to GHC 7.x and the packages
-were renamed::
+In Fedora, they are available via packages as well::
- $ apt-get install ghc libghc-json-dev libghc-network-dev \
- libghc-parallel-dev libghc-curl-dev \
- libghc-regex-pcre-dev
+ $ yum install ghc ghc-json-devel ghc-network-devel \
+ ghc-parallel-devel ghc-deepseq-devel
If using a distribution which does not provide them, first install
-the Haskell platform. You can also install ``cabal`` manualy::
+the Haskell platform. You can also install ``cabal`` manually::
$ apt-get install cabal-install
Then install the additional libraries via
``cabal``::
- $ cabal install json network parallel curl regex-pcre
+ $ cabal install json network parallel utf8-string
The compilation of the htools components is automatically enabled when
the compiler and the requisite libraries are found. You can use the
``--enable-htools`` configure flag to force the selection (at which
point ``./configure`` will fail if it doesn't find the prerequisites).
-In Ganeti version 2.6, one of the daemons (``ganeti-confd``) is shipped
-in two versions: the Python default version (which has no extra
-dependencies), and an experimental Haskell version. This latter version
-can be enabled via the ``./configure`` flag ``--enable-confd=haskell``
-and a few has extra dependencies:
+Haskell optional features
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Optionally, more functionality can be enabled if your build machine has
+a few more Haskell libraries enabled: RAPI access to remote cluster from
+htools (``--enable-htools-rapi``), the ``ganeti-confd``
+daemon (``--enable-confd``) and the monitoring agent
+(``--enable-monitoring``). The list of extra dependencies for these is:
+
+- `curl <http://hackage.haskell.org/package/curl>`_, tested with
+ versions 1.3.4 and above
- `hslogger <http://software.complete.org/hslogger>`_, version 1.1 and
above (note that Debian Squeeze only has version 1.0.9)
- `Crypto <http://hackage.haskell.org/package/Crypto>`_, tested with
version 4.2.4
- `text <http://hackage.haskell.org/package/text>`_
-- `hinotify <http://hackage.haskell.org/package/hinotify>`_
+- `hinotify <http://hackage.haskell.org/package/hinotify>`_, tested with
+ version 0.3.2
+- `regex-pcre <http://hackage.haskell.org/package/regex-pcre>`_,
+ bindings for the ``pcre`` library
+- `attoparsec <http://hackage.haskell.org/package/attoparsec>`_
+- `vector <http://hackage.haskell.org/package/vector>`_
