===========================
56
Installing from a Debian package
57
================================
59
Installing from source
60
======================
62
.. If this list changes, you also need to change the list above.
64
If you want to grab all of the required packages in one command, use::
66
sudo apt-get install apache2 libapache2-mod-python libapache2-svn \
67
python2.6 python-cjson python-configobj python-docutils python-epydoc \
68
python-formencode python-genshi python-psycopg2 python-svn python-routes \
69
python-storm libjs-jquery postgresql subversion debootstrap rsync \
72
While installing from a distribution package is often a better idea for
73
users, developers will need to install from a plain source tree.
75
To get the tree, either grab and extract a release tarball, or get the
76
very latest code using bzr: ::
80
You should then change into the new source directory.
82
As IVLE needs to compile some binaries, you must first build, then
86
sudo ./setup.py install
88
Unlike the package, you will have to manually set up the database and
91
First, it is recommended that you create a separate database user for IVLE.
92
You may use any name for the user. ::
94
sudo -u postgres createuser ivleuser # Answer 'n' to all questions
95
sudo -u postgres psql -c "ALTER USER ivleuser WITH ENCRYPTED PASSWORD 'ivle-password';"
97
Now, you must create a PostgreSQL database, and populate it with the
98
IVLE schema. You may use any name for the database (here we use ``ivle``). ::
100
sudo -u postgres createdb -O ivleuser ivle
101
sudo -u postgres createlang plpgsql ivle
102
psql -h localhost -W ivle ivleuser < userdb/users.sql
104
The configuration wizard - ``ivle-config`` - will ask you a series of
105
questions. You should give the database username and password as configured
106
above. Apart from database settings, the defaults should be correct
107
for a development system. If deploying IVLE properly - particularly on
108
multiple nodes - several options will need to be changed. Watching
117
.. Note: Place here only the configuration required to get the system
118
installed and running. Any further configuration should go in config.rst.
120
IVLE needs a directory hierarchy in which to store filesystem data, which
121
by default lives in ``/var/lib/ivle``. Create it now. ::
123
sudo ivle-createdatadirs
126
Configuring the jail environment
127
--------------------------------
129
You will require a self-contained jail environment in which to safely
130
execute student code.
131
Before you can actually build the jail, a few configuration options are
132
needed. Open up ``/etc/ivle/ivle.conf``, and find the ``[jail]`` section
133
(**not** the ``[[jails]]`` section).
137
suite = jaunty # Replace this with the codename of your Ubuntu release.
138
mirror = http://url.to.archive/mirror # Replace with a fast Ubuntu mirror.
139
extra_packages = python-configobj, python-svn, python-cjson
141
.. TODO: Move this around a bit, as the config options required differ for
142
the packaged version.
144
Now we can actually build the jail. The creation process basically downloads
145
a minimal Ubuntu system and installs it in ``/var/lib/ivle/jails/__base__``.
146
Note that this could download a couple of hundred megabytes. ::
148
sudo ivle-buildjail -r
153
IVLE makes use of two Apache virtual hosts: one for the application itself,
154
and one for the Subversion services. There are example configuration files
155
in ``examples/config/apache.conf`` and ``examples/config/apache-svn.conf``,
156
which will run IVLE at ``http://ivle.localhost/``.
158
On a Debian or Ubuntu system, just copy those two files into
159
``/etc/apache2/sites-available`` under appropriate names (eg. ``ivle`` and
160
``ivle-svn``). Then you need to activate them: ::
163
sudo a2ensite ivle-svn
164
sudo /etc/init.d/apache2 reload
167
Configuring hostname resolution
168
--------------------------------
170
All of IVLE's hostnames need to be resolvable from the local system. For a
171
production environment, this would be done in DNS. For a development system,
172
this is usually done in ``/etc/hosts``. Add this line to that file: ::
174
127.0.1.1 ivle.localhost public.ivle.localhost svn.ivle.localhost
176
Code running inside the jail environment also needs to be able to resolve
177
those names. Add, to ``/var/lib/ivle/jails/__base_build__/etc/hosts``: ::
179
127.0.1.1 svn.ivle.localhost
181
Then refresh the active copy of the jail: ::
186
Configuring the user management server
187
--------------------------------------
189
You need to have the IVLE user management server (``usrmgt-server``) running
190
for many parts of IVLE to operate properly, so it should be configured to
191
start on boot. There is an example init script in
192
``examples/config/usrmgt-server.init``. For Debian or Ubuntu, copy it to
193
``/etc/init.d/ivle-usrmgt-server``. Start it now, and set it to start
196
sudo /etc/init.d/ivle-usrmgt-server start
197
sudo update-rc.d ivle-usrmgt-server defaults 99
200
Creating the initial user
201
-------------------------
203
The final step in getting a usable IVLE set up is creating a user. You'll
204
probably want admin privileges - if not, drop the ``--admin``. ::
206
sudo ivle-adduser --admin -p password username 'Full Name'
208
You should then be able to browse to ``http://ivle.localhost/``, and
209
log in with that username and password.
