===========================
58
Installing from a Debian package
59
================================
63
Installing from source
64
======================
66
.. If this list changes, you also need to change the list above.
68
If you want to grab all of the required packages in one command, use::
70
sudo apt-get install apache2 libapache2-mod-python libapache2-svn \
71
python2.6 python-cjson python-configobj python-docutils python-epydoc \
72
python-formencode python-genshi python-psycopg2 python-svn python-routes \
73
python-storm libjs-jquery postgresql subversion debootstrap rsync \
76
While installing from a distribution package is often a better idea for
77
users, developers will need to install from a plain source tree.
79
To get the tree, either grab and extract a release tarball, or get the
80
very latest code using bzr: ::
84
You should then change into the new source directory.
86
As IVLE needs to compile some binaries, you must first build, then
90
sudo ./setup.py install
92
Unlike the package, you will have to manually set up the database and
95
First, it is recommended that you create a separate database user for IVLE.
96
You may use any name for the user. ::
98
sudo -u postgres createuser ivleuser # Answer 'n' to all questions
99
sudo -u postgres psql -c "ALTER USER ivleuser WITH ENCRYPTED PASSWORD 'ivle-password';"
101
Now, you must create a PostgreSQL database, and populate it with the
102
IVLE schema. You may use any name for the database (here we use ``ivle``). ::
104
sudo -u postgres createdb -O ivleuser ivle
105
sudo -u postgres createlang plpgsql ivle
106
psql -h localhost -W ivle ivleuser < userdb/users.sql
108
The configuration wizard - ``ivle-config`` - will ask you a series of
109
questions. You should give the database username and password as configured
110
above. Apart from database settings, the defaults should be correct
111
for a development system. If deploying IVLE properly - particularly on
112
multiple nodes - several options will need to be changed. Watching
121
.. Note: Place here only the configuration required to get the system
122
installed and running. Any further configuration should go in config.rst.
124
IVLE needs a directory hierarchy in which to store filesystem data, which
125
by default lives in ``/var/lib/ivle``. Create it now. ::
127
sudo ivle-createdatadirs
130
Configuring the jail environment
131
--------------------------------
133
You will require a self-contained jail environment in which to safely
134
execute student code.
135
Before you can actually build the jail, a few configuration options are
136
needed. Open up ``/etc/ivle/ivle.conf``, and find the ``[jail]`` section
137
(**not** the ``[[jails]]`` section).
141
suite = jaunty # Replace this with the codename of your Ubuntu release.
142
mirror = http://url.to.archive/mirror # Replace with a fast Ubuntu mirror.
143
extra_packages = python-configobj, python-svn, python-cjson
145
.. TODO: Move this around a bit, as the config options required differ for
146
the packaged version.
148
Now we can actually build the jail. The creation process basically downloads
149
a minimal Ubuntu system and installs it in ``/var/lib/ivle/jails/__base__``.
150
Note that this could download a couple of hundred megabytes. ::
152
sudo ivle-buildjail -r
157
IVLE makes use of two Apache virtual hosts: one for the application itself,
158
and one for the Subversion services. There are example configuration files
159
in ``examples/config/apache.conf`` and ``examples/config/apache-svn.conf``,
160
which will run IVLE at ``http://ivle.localhost/``.
162
On a Debian or Ubuntu system, just copy those two files into
163
``/etc/apache2/sites-available`` under appropriate names (eg. ``ivle`` and
164
``ivle-svn``). Then you need to activate them: ::
167
sudo a2ensite ivle-svn
168
sudo /etc/init.d/apache2 reload
171
Configuring hostname resolution
172
--------------------------------
174
All of IVLE's hostnames need to be resolvable from the local system. For a
175
production environment, this would be done in DNS. For a development system,
176
this is usually done in ``/etc/hosts``. Add this line to that file: ::
178
127.0.1.1 ivle.localhost public.ivle.localhost svn.ivle.localhost
180
Code running inside the jail environment also needs to be able to resolve
181
those names. Add, to ``/var/lib/ivle/jails/__base_build__/etc/hosts``: ::
183
127.0.1.1 svn.ivle.localhost
185
Then refresh the active copy of the jail: ::
190
Configuring the user management server
191
--------------------------------------
193
You need to have the IVLE user management server (``usrmgt-server``) running
194
for many parts of IVLE to operate properly, so it should be configured to
195
start on boot. There is an example init script in
196
``examples/config/usrmgt-server.init``. For Debian or Ubuntu, copy it to
197
``/etc/init.d/ivle-usrmgt-server``. Start it now, and set it to start
200
sudo /etc/init.d/ivle-usrmgt-server start
201
sudo update-rc.d ivle-usrmgt-server defaults 99
204
Creating the initial user
205
-------------------------
207
The final step in getting a usable IVLE set up is creating a user. You'll
208
probably want admin privileges - if not, drop the ``--admin``. ::
210
sudo ivle-adduser --admin -p password username 'Full Name'
212
You should then be able to browse to ``http://ivle.localhost/``, and
213
log in with that username and password.
