===========================
53
Installing from a Debian package
54
================================
56
Installing from source
57
======================
59
While installing from a distribution package is often a better idea for
60
users, developers will need to install from a plain source tree.
62
To get the tree, either grab and extract a release tarball, or get the
63
very latest code using bzr: ::
67
You should then change into the new source directory.
69
As IVLE needs to compile some binaries, you must first build, then
73
sudo ./setup.py install
75
Unlike the package, you will have to manually set up the database and
78
.. TODO: Separate IVLE PostgreSQL account.
80
First you must create a PostgreSQL database, and populate it with the
81
IVLE schema. You may use any name for the database. ::
83
sudo -u postgres createdb ivle
84
sudo -u postgres createlang plpgsql ivle
85
sudo -u postgres psql -d ivle < userdb/users.sql
87
The configuration wizard - ``ivle-config`` - will ask you a series of
88
questions. Apart from database settings, the defaults should be correct
89
for a development system. If deploying IVLE properly - particularly on
90
multiple nodes - several options will need to be changed. Watching
99
.. Note: Place here only the configuration required to get the system
100
installed and running. Any further configuration should go in config.rst.
102
IVLE needs a directory hierarchy in which to store filesystem data, which
103
by default lives in ``/var/lib/ivle``. Create it now. ::
105
sudo ivle-createdatadirs
108
Configuring the jail environment
109
--------------------------------
111
You will require a self-contained jail environment in which to safely
112
execute student code.
113
Before you can actually build the jail, a few configuration options are
114
needed. Open up ``/etc/ivle/ivle.conf``, and find the ``[jail]`` section.
118
suite = jaunty # Replace this with the codename of your Ubuntu release.
119
mirror = http://url.to.archive/mirror # Replace with a fast Ubuntu mirror.
120
extra_packages = python-configobj, python-svn, python-cjson
122
Now we can actually build the jail. The creation process basically downloads
123
a minimal Ubuntu system and installs it in ``/var/lib/ivle/jails/__base__``.
124
Note that this could download a couple of hundred megabytes. ::
126
sudo ivle-buildjail -r
131
IVLE makes use of two Apache virtual hosts: one for the application itself,
132
and one for the Subversion services. There are example configuration files
133
in ``examples/config/apache.conf`` and ``examples/config/apache-svn.conf``,
134
which will run IVLE at ``http://ivle.localhost/``.
136
On a Debian or Ubuntu system, just copy those two files into
137
``/etc/apache2/sites-available`` under appropriate names (eg. ``ivle`` and
138
``ivle-svn``). Then you need to activate them: ::
141
sudo a2ensite ivle-svn
142
sudo /etc/init.d/apache2 reload
145
Configuring hostname resolution
146
--------------------------------
148
All of IVLE's hostnames need to be resolvable from the local system. For a
149
production environment, this would be done in DNS. For a development system,
150
this is usually done in ``/etc/hosts``. Add this line to that file: ::
152
127.0.1.1 ivle.localhost public.ivle.localhost svn.ivle.localhost
154
Code running inside the jail environment also needs to be able to resolve
155
those names. Add, to ``/var/lib/ivle/jails/__base_build__/etc/hosts``: ::
157
127.0.1.1 svn.ivle.localhost
159
Then refresh the active copy of the jail: ::
164
Configuring the user management server
165
--------------------------------------
167
You need to have the IVLE user management server (``usrmgt-server``) running
168
for many parts of IVLE to operate properly, so it should be configured to
169
start on boot. There is an example init script in
170
``examples/config/usrmgt-server.init``. For Debian or Ubuntu, copy it to
171
``/etc/init.d/ivle``. Start it now, and set it to start automatically: ::
173
sudo /etc/init.d/usrmgt-server start
174
sudo update-rc.d usrmgt-server defaults 99
177
