Build dependencies |
5 |
------------------ |
6 |
|
7 |
Most dependencies from :doc:`install-quick`, plus: |
8 |
|
9 |
- `GNU make <http://www.gnu.org/software/make/>`_ |
10 |
- `GNU tar <http://www.gnu.org/software/tar/>`_ |
11 |
- `Gzip <http://www.gnu.org/software/gzip/>`_ |
12 |
- `pandoc <http://johnmacfarlane.net/pandoc/>`_ |
13 |
- `python-sphinx <http://sphinx.pocoo.org/>`_ |
14 |
(tested with version 0.6.1) |
15 |
- `graphviz <http://www.graphviz.org/>`_ |
16 |
- the `en_US.UTF-8` locale must be enabled on the system |
17 |
|
18 |
To generate unittest coverage reports (``make coverage``), `coverage |
19 |
<http://pypi.python.org/pypi/coverage>`_ needs to be installed. |

Configuring for development |
23 |
--------------------------- |
24 |
|
25 |
.. highlight:: sh |
26 |
|
27 |
Run the following command (only use ``PYTHON=...`` if you need to use a |
28 |
different python version):: |
29 |
|
30 |
./autogen.sh && \ |
31 |
./configure --prefix=/usr/local --sysconfdir=/etc --localstatedir=/var |

Packaging notes |
35 |
=============== |
36 |
|
37 |
Ganeti is mostly developped and tested on `Debian |
38 |
<http://www.debian.org/>`_-based distributions, while still keeping |
39 |
adoptability to other Linux distributions in mind. |
40 |
|
41 |
The ``doc/examples/`` directory contains a number of potentially useful |
42 |
scripts and configuration files. Some of them might need adjustment |
43 |
before use. |
44 |
|
45 |
``daemon-util`` |
46 |
--------------- |
47 |
|
48 |
This script, in the source code as ``daemons/daemon-util.in``, is used |
49 |
to start/stop Ganeti and do a few other things related to system |
50 |
daemons. Is is recommended to use ``daemon-util`` also from the system's |
51 |
init scripts. That way the code starting and stopping daemons is shared |
52 |
and future changes have to be made in only one place. |
53 |
|
54 |
``daemon-util`` reads extra arguments from variables (``*_ARGS``) in |
55 |
``/etc/default/ganeti``. When modifying ``daemon-util``, keep in mind to |
56 |
not remove support for the ``EXTRA_*_ARGS`` variables for starting |
57 |
daemons. Some parts of Ganeti use them to pass additional arguments when |
58 |
starting a daemon. |
59 |
|
60 |
The ``reload_ssh_keys`` function can be adjusted to use another command |
61 |
for reloading the OpenSSH daemon's host keys. |
