53 | c27ba1cc | Michael Hanselmann | These programs are supplied as part of most Linux distributions, so |
54 | c27ba1cc | Michael Hanselmann | usually they can be installed via the standard package manager. Also |
55 | c27ba1cc | Michael Hanselmann | many of them will already be installed on a standard machine. On |
56 | c27ba1cc | Michael Hanselmann | Debian/Ubuntu, you can use this command line to install all required |

72 | 727ee1ec | Iustin Pop | If you want to build from source, please see doc/devnotes.rst for more |
73 | 727ee1ec | Iustin Pop | dependencies. |
74 | 727ee1ec | Iustin Pop | |
75 | 727ee1ec | Iustin Pop | .. _socat-note: |
76 | 727ee1ec | Iustin Pop | .. note:: |
77 | 727ee1ec | Iustin Pop | Ganeti's import/export functionality uses ``socat`` with OpenSSL for |
78 | 727ee1ec | Iustin Pop | transferring data between nodes. By default, OpenSSL 0.9.8 and above |
79 | 727ee1ec | Iustin Pop | employ transparent compression of all data using zlib if supported by |
80 | 727ee1ec | Iustin Pop | both sides of a connection. In cases where a lot of data is |
81 | 727ee1ec | Iustin Pop | transferred, this can lead to an increased CPU usage. Additionally, |
82 | 727ee1ec | Iustin Pop | Ganeti already compresses all data using ``gzip`` where it makes sense |
83 | 727ee1ec | Iustin Pop | (for inter-cluster instance moves). |
84 | 727ee1ec | Iustin Pop | |
85 | 727ee1ec | Iustin Pop | To remedey this situation, patches implementing a new ``socat`` option |
86 | 727ee1ec | Iustin Pop | for disabling OpenSSL compression have been contributed and will |
87 | 727ee1ec | Iustin Pop | likely be included in the next feature release. Until then, users or |
88 | 727ee1ec | Iustin Pop | distributions need to apply the patches on their own. |
89 | 727ee1ec | Iustin Pop | |
90 | 727ee1ec | Iustin Pop | Ganeti will use the option if it's detected by the ``configure`` |
91 | 727ee1ec | Iustin Pop | script; auto-detection can be disabled by explicitely passing |
92 | 727ee1ec | Iustin Pop | ``--enable-socat-compress`` (use the option to disable compression) or |
93 | 727ee1ec | Iustin Pop | ``--disable-socat-compress`` (don't use the option). |
94 | 727ee1ec | Iustin Pop | |
95 | 727ee1ec | Iustin Pop | The patches and more information can be found on |
96 | 727ee1ec | Iustin Pop | http://www.dest-unreach.org/socat/contrib/socat-opensslcompress.html. |
97 | 727ee1ec | Iustin Pop | |
98 | 727ee1ec | Iustin Pop | Haskell requirements |
99 | 727ee1ec | Iustin Pop | ~~~~~~~~~~~~~~~~~~~~ |
100 | 727ee1ec | Iustin Pop | |
101 | 727ee1ec | Iustin Pop | If you want to enable the `htools` component, which is recommended on |
102 | 727ee1ec | Iustin Pop | bigger deployments (this give you automatic instance placement, cluster |
103 | 727ee1ec | Iustin Pop | balancing, etc.), then you need to have a Haskell compiler installed on |
104 | 727ee1ec | Iustin Pop | your build machine (but this is not required on the machines which are |
105 | 727ee1ec | Iustin Pop | just going to run Ganeti). More specifically: |
106 | 77a180f6 | Iustin Pop | |
107 | 7345b69b | Iustin Pop | - `GHC <http://www.haskell.org/ghc/>`_ version 6.12 or higher |
108 | 77a180f6 | Iustin Pop | - or even better, `The Haskell Platform |
109 | 77a180f6 | Iustin Pop | <http://hackage.haskell.org/platform/>`_ which gives you a simple way |
110 | 77a180f6 | Iustin Pop | to bootstrap Haskell |
111 | 77a180f6 | Iustin Pop | - `json <http://hackage.haskell.org/package/json>`_, a JSON library |
112 | 77a180f6 | Iustin Pop | - `network <http://hackage.haskell.org/package/network>`_, a basic |
113 | 77a180f6 | Iustin Pop | network library |
114 | ee041788 | Iustin Pop | - `parallel <http://hackage.haskell.org/package/parallel>`_, a parallel |
115 | ee041788 | Iustin Pop | programming library (note: tested with up to version 3.x) |
116 | 77a180f6 | Iustin Pop | - `curl <http://hackage.haskell.org/package/curl>`_, bindings for the |
117 | 77a180f6 | Iustin Pop | curl library, only needed if you want these tools to connect to remote |
118 | 77a180f6 | Iustin Pop | clusters (as opposed to the local one) |
119 | 77a180f6 | Iustin Pop | |
120 | 77a180f6 | Iustin Pop | All of these are also available as package in Debian/Ubuntu:: |
121 | 77a180f6 | Iustin Pop | |
122 | 77a180f6 | Iustin Pop | $ apt-get install ghc6 libghc6-json-dev libghc6-network-dev \ |
123 | 77a180f6 | Iustin Pop | libghc6-parallel-dev libghc6-curl-dev |
124 | 77a180f6 | Iustin Pop | |
125 | aa9f166a | René Nussbaumer | Or in Fedora running:: |
126 | aa9f166a | René Nussbaumer | |
127 | aa9f166a | René Nussbaumer | $ yum install ghc ghc-json-devel ghc-network-devel ghc-parallel-devel |
128 | aa9f166a | René Nussbaumer | |
129 | aa9f166a | René Nussbaumer | The most recent Fedora doesn't provide ``ghc-curl``. So this needs to be |
130 | aa9f166a | René Nussbaumer | installed using ``cabal`` or alternatively htools can be build without |
131 | aa9f166a | René Nussbaumer | curl support. |
132 | aa9f166a | René Nussbaumer | |
133 | ee041788 | Iustin Pop | Note that more recent version have switched to GHC 7.x and the packages |
134 | ee041788 | Iustin Pop | were renamed:: |
135 | ee041788 | Iustin Pop | |
136 | ee041788 | Iustin Pop | $ apt-get install ghc libghc-json-dev libghc-network-dev \ |
137 | ee041788 | Iustin Pop | libghc-parallel-dev libghc-curl-dev |
138 | ee041788 | Iustin Pop | |
139 | 727ee1ec | Iustin Pop | If using a distribution which does not provide them, the first install |
140 | 727ee1ec | Iustin Pop | the Haskell platform and then install the additional libraries via |
141 | 727ee1ec | Iustin Pop | ``cabal``:: |
142 | 727ee1ec | Iustin Pop | |
143 | 727ee1ec | Iustin Pop | $ cabal install json network parallel curl |
144 | 727ee1ec | Iustin Pop | |
145 | 1ebe6dbd | Iustin Pop | The compilation of the htools components is automatically enabled when |
146 | 1ebe6dbd | Iustin Pop | the compiler and the requisite libraries are found. You can use the |
147 | 1ebe6dbd | Iustin Pop | ``--enable-htools`` configure flag to force the selection (at which |
148 | 1ebe6dbd | Iustin Pop | point ``./configure`` will fail if it doesn't find the prerequisites). |
149 | 1ebe6dbd | Iustin Pop | |
150 | 727ee1ec | Iustin Pop | In Ganeti version 2.6, one of the daemons (``ganeti-confd``) is shipped |
151 | 727ee1ec | Iustin Pop | in two versions: the Python default version (which has no extra |
152 | 727ee1ec | Iustin Pop | dependencies), and an experimental Haskell version. This latter version |
153 | 727ee1ec | Iustin Pop | can be enabled via the ``./configure`` flag ``--enable-confd=haskell`` |
154 | 727ee1ec | Iustin Pop | and a few has extra dependencies: |
155 | 5cd0d9c0 | Iustin Pop | |
156 | 727ee1ec | Iustin Pop | - `hslogger <http://software.complete.org/hslogger>`_, version 1.1 and |
157 | 727ee1ec | Iustin Pop | above (note that Debian Squeeze only has version 1.0.9) |
158 | 727ee1ec | Iustin Pop | - `Crypto <http://hackage.haskell.org/package/Crypto>`_, tested with |
159 | 727ee1ec | Iustin Pop | version 4.2.4 |
160 | 727ee1ec | Iustin Pop | - `text <http://hackage.haskell.org/package/text>`_ |
161 | 727ee1ec | Iustin Pop | - ``bytestring``, which usually comes with the compiler |
162 | e90739d6 | Michael Hanselmann | |
163 | 727ee1ec | Iustin Pop | These libraries are available in Debian Wheezy (but not in Squeeze), so |
164 | 727ee1ec | Iustin Pop | you can use either apt:: |
165 | e90739d6 | Michael Hanselmann | |
166 | 727ee1ec | Iustin Pop | $ apt-get install libghc-hslogger-dev libghc-crypto-dev libghc-text-dev |
167 | e90739d6 | Michael Hanselmann | |
168 | 727ee1ec | Iustin Pop | or ``cabal``:: |
169 | 727ee1ec | Iustin Pop | |
170 | 727ee1ec | Iustin Pop | $ cabal install hslogger Crypto text |
171 | e90739d6 | Michael Hanselmann | |
172 | 727ee1ec | Iustin Pop | to install them. |
173 | bd785ecd | Michael Hanselmann | |
174 | bd785ecd | Michael Hanselmann | Installation of the software |
175 | c27ba1cc | Michael Hanselmann | ---------------------------- |
176 | c27ba1cc | Michael Hanselmann | |
177 | c27ba1cc | Michael Hanselmann | To install, simply run the following command:: |
178 | a8083063 | Iustin Pop | |
179 | 727ee1ec | Iustin Pop | $ ./configure --localstatedir=/var --sysconfdir=/etc && \ |
180 | 727ee1ec | Iustin Pop | make && \ |
181 | 727ee1ec | Iustin Pop | make install |
182 | a8083063 | Iustin Pop | |
183 | c27ba1cc | Michael Hanselmann | This will install the software under ``/usr/local``. You then need to |
184 | c27ba1cc | Michael Hanselmann | copy ``doc/examples/ganeti.initd`` to ``/etc/init.d/ganeti`` and |
185 | c27ba1cc | Michael Hanselmann | integrate it into your boot sequence (``chkconfig``, ``update-rc.d``, |
186 | c27ba1cc | Michael Hanselmann | etc.). |
187 | a8083063 | Iustin Pop | |
188 | bd785ecd | Michael Hanselmann | |
189 | a8083063 | Iustin Pop | Cluster initialisation |
190 | c27ba1cc | Michael Hanselmann | ---------------------- |
191 | a8083063 | Iustin Pop | |
192 | c27ba1cc | Michael Hanselmann | Before initialising the cluster, on each node you need to create the |
193 | c27ba1cc | Michael Hanselmann | following directories: |
194 | a8083063 | Iustin Pop | |
195 | c27ba1cc | Michael Hanselmann | - ``/etc/ganeti`` |
196 | c27ba1cc | Michael Hanselmann | - ``/var/lib/ganeti`` |
197 | c27ba1cc | Michael Hanselmann | - ``/var/log/ganeti`` |
198 | c27ba1cc | Michael Hanselmann | - ``/srv/ganeti`` |
199 | c27ba1cc | Michael Hanselmann | - ``/srv/ganeti/os`` |
200 | c27ba1cc | Michael Hanselmann | - ``/srv/ganeti/export`` |
201 | a8083063 | Iustin Pop | |
202 | a8083063 | Iustin Pop | After this, use ``gnt-cluster init``. |
