51 | c27ba1cc | Michael Hanselmann | These programs are supplied as part of most Linux distributions, so |
52 | c27ba1cc | Michael Hanselmann | usually they can be installed via the standard package manager. Also |
53 | c27ba1cc | Michael Hanselmann | many of them will already be installed on a standard machine. On |
54 | c27ba1cc | Michael Hanselmann | Debian/Ubuntu, you can use this command line to install all required |
55 | 7ed400f0 | Stratos Psomadakis | packages, except for RBD, DRBD and Xen:: |
56 | c27ba1cc | Michael Hanselmann | |
57 | c27ba1cc | Michael Hanselmann | $ apt-get install lvm2 ssh bridge-utils iproute iputils-arping \ |
58 | 69affe73 | Manuel Franceschini | ndisc6 python python-pyopenssl openssl \ |

66 | fc6075dd | Agata Murawska | |
67 | fc6075dd | Agata Murawska | If some of the python packages are not available in your system, |
68 | fc6075dd | Agata Murawska | you can try installing them using ``easy_install`` command. |
69 | fc6075dd | Agata Murawska | For example:: |
70 | fc6075dd | Agata Murawska | |
71 | 958a800a | Michele Tartara | $ apt-get install python-setuptools python-dev |
72 | fc6075dd | Agata Murawska | $ cd / && sudo easy_install \ |

88 | 727ee1ec | Iustin Pop | If you want to build from source, please see doc/devnotes.rst for more |
89 | 727ee1ec | Iustin Pop | dependencies. |
90 | 727ee1ec | Iustin Pop | |
91 | 727ee1ec | Iustin Pop | .. _socat-note: |
92 | 727ee1ec | Iustin Pop | .. note:: |
93 | 727ee1ec | Iustin Pop | Ganeti's import/export functionality uses ``socat`` with OpenSSL for |
94 | 727ee1ec | Iustin Pop | transferring data between nodes. By default, OpenSSL 0.9.8 and above |
95 | 727ee1ec | Iustin Pop | employ transparent compression of all data using zlib if supported by |
96 | 727ee1ec | Iustin Pop | both sides of a connection. In cases where a lot of data is |
97 | 727ee1ec | Iustin Pop | transferred, this can lead to an increased CPU usage. Additionally, |
98 | 727ee1ec | Iustin Pop | Ganeti already compresses all data using ``gzip`` where it makes sense |
99 | 727ee1ec | Iustin Pop | (for inter-cluster instance moves). |
100 | 727ee1ec | Iustin Pop | |
101 | 727ee1ec | Iustin Pop | To remedey this situation, patches implementing a new ``socat`` option |
102 | 727ee1ec | Iustin Pop | for disabling OpenSSL compression have been contributed and will |
103 | 727ee1ec | Iustin Pop | likely be included in the next feature release. Until then, users or |
104 | 727ee1ec | Iustin Pop | distributions need to apply the patches on their own. |
105 | 727ee1ec | Iustin Pop | |
106 | 727ee1ec | Iustin Pop | Ganeti will use the option if it's detected by the ``configure`` |
107 | 2ed0e208 | Iustin Pop | script; auto-detection can be disabled by explicitly passing |
108 | 727ee1ec | Iustin Pop | ``--enable-socat-compress`` (use the option to disable compression) or |
109 | 727ee1ec | Iustin Pop | ``--disable-socat-compress`` (don't use the option). |
110 | 727ee1ec | Iustin Pop | |
111 | 727ee1ec | Iustin Pop | The patches and more information can be found on |
112 | 727ee1ec | Iustin Pop | http://www.dest-unreach.org/socat/contrib/socat-opensslcompress.html. |
113 | 727ee1ec | Iustin Pop | |
114 | 727ee1ec | Iustin Pop | Haskell requirements |
115 | 727ee1ec | Iustin Pop | ~~~~~~~~~~~~~~~~~~~~ |
116 | 727ee1ec | Iustin Pop | |
117 | 21a5e56c | Iustin Pop | Starting with Ganeti 2.7, the Haskell GHC compiler and a few base |
118 | 21a5e56c | Iustin Pop | libraries are required in order to build Ganeti (but not to run and |
119 | 21a5e56c | Iustin Pop | deploy Ganeti on production machines). More specifically: |
120 | 77a180f6 | Iustin Pop | |
121 | 7345b69b | Iustin Pop | - `GHC <http://www.haskell.org/ghc/>`_ version 6.12 or higher |
122 | 77a180f6 | Iustin Pop | - or even better, `The Haskell Platform |
123 | 77a180f6 | Iustin Pop | <http://hackage.haskell.org/platform/>`_ which gives you a simple way |
124 | 77a180f6 | Iustin Pop | to bootstrap Haskell |
125 | 77a180f6 | Iustin Pop | - `json <http://hackage.haskell.org/package/json>`_, a JSON library |
126 | 77a180f6 | Iustin Pop | - `network <http://hackage.haskell.org/package/network>`_, a basic |
127 | 77a180f6 | Iustin Pop | network library |
128 | ee041788 | Iustin Pop | - `parallel <http://hackage.haskell.org/package/parallel>`_, a parallel |
129 | ee041788 | Iustin Pop | programming library (note: tested with up to version 3.x) |
130 | e821050d | Iustin Pop | - `bytestring <http://hackage.haskell.org/package/bytestring>`_ and |
131 | e821050d | Iustin Pop | `utf8-string <http://hackage.haskell.org/package/utf8-string>`_ |
132 | e821050d | Iustin Pop | libraries; these usually come with the GHC compiler |
133 | 21a5e56c | Iustin Pop | - `deepseq <http://hackage.haskell.org/package/deepseq>`_ |
134 | 1ca709c1 | Iustin Pop | - `curl <http://hackage.haskell.org/package/curl>`_, tested with |
135 | 1ca709c1 | Iustin Pop | versions 1.3.4 and above |
136 | 77a180f6 | Iustin Pop | |
137 | 8a65c02b | Iustin Pop | Some of these are also available as package in Debian/Ubuntu:: |
138 | 77a180f6 | Iustin Pop | |
139 | 77a180f6 | Iustin Pop | $ apt-get install ghc6 libghc6-json-dev libghc6-network-dev \ |
140 | 1ca709c1 | Iustin Pop | libghc6-parallel-dev libghc6-deepseq-dev \ |
141 | 1ca709c1 | Iustin Pop | libghc6-curl-dev |
142 | aa9f166a | René Nussbaumer | |
143 | 21a5e56c | Iustin Pop | Or in newer versions of these distributions (using GHC 7.x):: |
144 | aa9f166a | René Nussbaumer | |
145 | 21a5e56c | Iustin Pop | $ apt-get install ghc libghc-json-dev libghc-network-dev \ |
146 | 1ca709c1 | Iustin Pop | libghc-parallel-dev libghc-deepseq-dev \ |
147 | 1ca709c1 | Iustin Pop | libghc-utf8-string-dev libghc-curl-dev |
148 | aa9f166a | René Nussbaumer | |
149 | 1ca709c1 | Iustin Pop | In Fedora, some of them are available via packages as well:: |
150 | ee041788 | Iustin Pop | |
151 | 21a5e56c | Iustin Pop | $ yum install ghc ghc-json-devel ghc-network-devel \ |
152 | 21a5e56c | Iustin Pop | ghc-parallel-devel ghc-deepseq-devel |
153 | ee041788 | Iustin Pop | |
154 | fc6075dd | Agata Murawska | If using a distribution which does not provide them, first install |
155 | 21a5e56c | Iustin Pop | the Haskell platform. You can also install ``cabal`` manually:: |
156 | fc6075dd | Agata Murawska | |
157 | fc6075dd | Agata Murawska | $ apt-get install cabal-install |
158 | fc6075dd | Agata Murawska | |
159 | fc6075dd | Agata Murawska | Then install the additional libraries via |
160 | 727ee1ec | Iustin Pop | ``cabal``:: |
161 | 727ee1ec | Iustin Pop | |
162 | 1ca709c1 | Iustin Pop | $ cabal install json network parallel utf8-string curl |
163 | 5cd0d9c0 | Iustin Pop | |
164 | 21a5e56c | Iustin Pop | Haskell optional features |
165 | 21a5e56c | Iustin Pop | ~~~~~~~~~~~~~~~~~~~~~~~~~ |
166 | 21a5e56c | Iustin Pop | |
167 | 21a5e56c | Iustin Pop | Optionally, more functionality can be enabled if your build machine has |
168 | 1ca709c1 | Iustin Pop | a few more Haskell libraries enabled: the ``ganeti-confd`` daemon |
169 | 2fa8f963 | Michele Tartara | (``--enable-confd``) and the monitoring daemon |
170 | 2fa8f963 | Michele Tartara | (``--enable-mond``). The list of extra dependencies for these is: |
171 | 21a5e56c | Iustin Pop | |
172 | 727ee1ec | Iustin Pop | - `hslogger <http://software.complete.org/hslogger>`_, version 1.1 and |
173 | 727ee1ec | Iustin Pop | above (note that Debian Squeeze only has version 1.0.9) |
174 | 727ee1ec | Iustin Pop | - `Crypto <http://hackage.haskell.org/package/Crypto>`_, tested with |
175 | 727ee1ec | Iustin Pop | version 4.2.4 |
176 | 727ee1ec | Iustin Pop | - `text <http://hackage.haskell.org/package/text>`_ |
177 | fe7ad9c8 | Iustin Pop | - `hinotify <http://hackage.haskell.org/package/hinotify>`_, tested with |
178 | fe7ad9c8 | Iustin Pop | version 0.3.2 |
179 | 21a5e56c | Iustin Pop | - `regex-pcre <http://hackage.haskell.org/package/regex-pcre>`_, |
180 | 21a5e56c | Iustin Pop | bindings for the ``pcre`` library |
181 | 35c6e63d | Michele Tartara | - `attoparsec <http://hackage.haskell.org/package/attoparsec>`_ |
182 | fcc1977b | Helga Velroyen | - `vector <http://hackage.haskell.org/package/vector>`_ |
183 | 2fa8f963 | Michele Tartara | - `snap-server` <http://hackage.haskell.org/package/snap-server>`_, version |
184 | 2fa8f963 | Michele Tartara | 0.8.1 and above. |
185 | e90739d6 | Michael Hanselmann | |
186 | 21a5e56c | Iustin Pop | These libraries are available in Debian Wheezy (but not in Squeeze, with |
187 | 21a5e56c | Iustin Pop | the exception of curl), so you can use either apt:: |
188 | e90739d6 | Michael Hanselmann | |
189 | e0e3586a | Agata Murawska | $ apt-get install libghc-hslogger-dev libghc-crypto-dev libghc-text-dev \ |
190 | 1ca709c1 | Iustin Pop | libghc-hinotify-dev libghc-regex-pcre-dev \ |
191 | 2fa8f963 | Michele Tartara | libghc-attoparsec-dev libghc-vector-dev \ |
192 | 2fa8f963 | Michele Tartara | libghc-snap-server-dev |
193 | e90739d6 | Michael Hanselmann | |
194 | 44b7a8a8 | Michele Tartara | or ``cabal``, after installing a required non-Haskell dependency:: |
195 | 727ee1ec | Iustin Pop | |
196 | 958a800a | Michele Tartara | $ apt-get install libpcre3-dev |
197 | 1ca709c1 | Iustin Pop | $ cabal install hslogger Crypto text hinotify regex-pcre \ |
198 | 2fa8f963 | Michele Tartara | attoparsec vector snap-server |
199 | e90739d6 | Michael Hanselmann | |
200 | 727ee1ec | Iustin Pop | to install them. |
201 | bd785ecd | Michael Hanselmann | |
202 | 2fa8f963 | Michele Tartara | In case you still use ghc-6.12, note that ``cabal`` would automatically try to |
203 | 2fa8f963 | Michele Tartara | install newer versions of some of the libraries snap-server depends on, that |
204 | 2fa8f963 | Michele Tartara | cannot be compiled with ghc-6.12, so you have to install snap-server on its |
205 | 2fa8f963 | Michele Tartara | own, esplicitly forcing the installation of compatible versions:: |
206 | 2fa8f963 | Michele Tartara | |
207 | 2fa8f963 | Michele Tartara | $ cabal install MonadCatchIO-transformers==0.2.2.0 mtl==2.0.1.0 \ |
208 | 2fa8f963 | Michele Tartara | hashable==1.1.2.0 case-insensitive==0.3 parsec==3.0.1 \ |
209 | 2fa8f963 | Michele Tartara | network==2.3 snap-server==0.8.1 |
210 | 2fa8f963 | Michele Tartara | |
211 | 1ca709c1 | Iustin Pop | The most recent Fedora doesn't provide ``crypto``, ``inotify``. So these |
212 | 1ca709c1 | Iustin Pop | need to be installed using ``cabal``, if desired. The other packages can |
213 | 1ca709c1 | Iustin Pop | be installed via ``yum``:: |
214 | 21a5e56c | Iustin Pop | |
215 | 21a5e56c | Iustin Pop | $ yum install ghc-hslogger-devel ghc-text-devel \ |
216 | 21a5e56c | Iustin Pop | ghc-regex-pcre-devel |
217 | 21a5e56c | Iustin Pop | |
218 | fc6075dd | Agata Murawska | .. _cabal-note: |
219 | fc6075dd | Agata Murawska | .. note:: |
220 | fc6075dd | Agata Murawska | If one of the cabal packages fails to install due to unfulfilled |
221 | fc6075dd | Agata Murawska | dependencies, you can try enabling symlinks in ``~/.cabal/config``. |
222 | fc6075dd | Agata Murawska | |
223 | fc6075dd | Agata Murawska | Make sure that your ``~/.cabal/bin`` directory (or whatever else |
224 | fc6075dd | Agata Murawska | is defined as ``bindir``) is in your ``PATH``. |
225 | fc6075dd | Agata Murawska | |
226 | bd785ecd | Michael Hanselmann | Installation of the software |
227 | c27ba1cc | Michael Hanselmann | ---------------------------- |
228 | c27ba1cc | Michael Hanselmann | |
229 | c27ba1cc | Michael Hanselmann | To install, simply run the following command:: |
230 | a8083063 | Iustin Pop | |
231 | 727ee1ec | Iustin Pop | $ ./configure --localstatedir=/var --sysconfdir=/etc && \ |
232 | 727ee1ec | Iustin Pop | make && \ |
233 | 727ee1ec | Iustin Pop | make install |
234 | a8083063 | Iustin Pop | |
235 | c27ba1cc | Michael Hanselmann | This will install the software under ``/usr/local``. You then need to |
236 | c27ba1cc | Michael Hanselmann | copy ``doc/examples/ganeti.initd`` to ``/etc/init.d/ganeti`` and |
237 | c27ba1cc | Michael Hanselmann | integrate it into your boot sequence (``chkconfig``, ``update-rc.d``, |
238 | c27ba1cc | Michael Hanselmann | etc.). |
239 | a8083063 | Iustin Pop | |
240 | bd785ecd | Michael Hanselmann | |
241 | a8083063 | Iustin Pop | Cluster initialisation |
242 | c27ba1cc | Michael Hanselmann | ---------------------- |
243 | a8083063 | Iustin Pop | |
244 | c27ba1cc | Michael Hanselmann | Before initialising the cluster, on each node you need to create the |
245 | c27ba1cc | Michael Hanselmann | following directories: |
246 | a8083063 | Iustin Pop | |
247 | c27ba1cc | Michael Hanselmann | - ``/etc/ganeti`` |
248 | c27ba1cc | Michael Hanselmann | - ``/var/lib/ganeti`` |
249 | c27ba1cc | Michael Hanselmann | - ``/var/log/ganeti`` |
250 | c27ba1cc | Michael Hanselmann | - ``/srv/ganeti`` |
251 | c27ba1cc | Michael Hanselmann | - ``/srv/ganeti/os`` |
252 | c27ba1cc | Michael Hanselmann | - ``/srv/ganeti/export`` |
253 | a8083063 | Iustin Pop | |
254 | a8083063 | Iustin Pop | After this, use ``gnt-cluster init``. |
