Invenio installation
====================
1. About
--------
This document specifies how to quickly install Invenio v2.0.0 for the first
time. See RELEASE-NOTES if you are upgrading from a previous Invenio release.
2. Prerequisites
----------------
Here is the software you need to have around before you start installing
Invenio for development.
Unix-like operating system. The main development and production platforms for
Invenio at CERN are GNU/Linux distributions Debian, Gentoo, Scientific Linux
(RHEL-based), Ubuntu, but we also develop on Mac OS X. Basically any Unix
system supporting the software listed below should do.
2.1. Debian / Ubuntu LTS
~~~~~~~~~~~~~~~~~~~~~~~~
If you are using Ubuntu 13.10 or later, then you can install Invenio by
following this tutorial. **Note:** the recommended Python version is 2.7.5+
.. code-block:: console
$ python --version
Python 2.7.5+
$ sudo apt-get update
$ sudo apt-get install build-essential git redis-server \
libmysqlclient-dev libxml2-dev libxslt-dev \
libjpeg-dev libfreetype6-dev libtiff-dev \
software-properties-common python-dev \
virtualenvwrapper
$ sudo pip install -U virtualenvwrapper pip
$ source .bashrc
2.1.1. MySQL
++++++++++++
MySQL Server will ask you for a password, you will need it later and we will
refer to it as ``$MYSQL_ROOT``.
.. code-block:: console
$ sudo apt-get install mysql-server
2.1.2. Node.js
++++++++++++++
`node.js <http://nodejs.org/>`_ and `npm <https://www.npmjs.org/>`_ from Ubuntu
are troublesome so we recommend you to install them from Chris Lea's PPA.
.. code-block:: console
$ sudo add-apt-repository ppa:chris-lea/node.js
$ sudo apt-get update
$ sudo apt-get install nodejs
2.2. Centos / RHEL
~~~~~~~~~~~~~~~~~~
If you are using Redhat, Centos or Scientific Linux this will setup everything
you need. We are assuming that sudo has been installed and configured nicely.
.. code-block:: console
$ python --version
2.6.6
$ sudo yum update
$ sudo rpm -Uvh http://mirror.switch.ch/ftp/mirror/epel/6/i386/epel-release-6-8.noarch.rpm
$ sudo yum -q -y groupinstall "Development Tools"
$ sudo yum install git wget redis python-devel \
mysql-devel libxml2-devel libxslt-devel \
python-pip python-virtualenvwrapper
$ sudo service redis start
$ sudo pip install -U virtualenvwrapper pip
$ source /usr/bin/virtualenvwrapper.sh
2.2.1. MySQL
++++++++++++
Setting up MySQL Server requires you to give some credentials for the root
user. You will need the root password later on and we will refer to it as
``$MYSQL_ROOT``.
.. code-block:: console
$ sudo yum install mysql-server
$ sudo service msyqld status
mysqld is stopped
$ sudo service mysqld start
$ sudo mysql_secure_installation
# follow the instructions
2.2.2. Node.js
++++++++++++++
Node.js requires a bit more manual work to install it from the sources. We are
following the tutorial: `digital ocean: tutorial on how to install node.js on
centor
<https://www.digitalocean.com/community/tutorials/how-to-install-and-run-a-node-js-app-on-centos-6-4-64bit>`_
.. code-block:: console
$ mkdir opt
$ cd opt
$ wget http://nodejs.org/dist/v0.10.29/node-v0.10.29.tar.gz
$ tar xvf node-v0.10.29.tar.gz
$ cd node-v0.10.29
$ ./configure
$ make
$ sudo make install
$ node --version
v0.10.29
$ npm --version
1.4.14
2.3. Extra tools
~~~~~~~~~~~~~~~~
2.3.1. Bower and Grunt
++++++++++++++++++++++
Bower and Grunt as used to manage the static assets such as JavaScript
libraries (e.g., jQuery) and CSS stylesheets (e.g., Bootstrap), it's much
easier to install them globally.
.. code-block:: console
$ sudo su -c "npm install -g bower grunt-cli"
2.3.2 ``git-new-workdir``
++++++++++++++++++++++++++
For the rest of the tutorial you will need to check that you have ``git-new-workdir``.
.. code-block:: console
$ mkdir -p $HOME/bin
$ which git-new-workdir || { \
wget https://raw.github.com/git/git/master/contrib/workdir/git-new-workdir \
-O $HOME/bin/git-new-workdir; chmod +x $HOME/bin/git-new-workdir; }
**NOTE:** Check that ``~/bin`` is in your ``$PATH``.
.. code-block:: console
$ export PATH+=:$HOME/bin
3. Quick instructions for the impatient Invenio admin
------------------------------------------------------
3.1. Installation
~~~~~~~~~~~~~~~~~
The first step of the installation is to download the development version of
Invenio. This development is done in the ``pu`` branch.
.. code-block:: console
$ cd $HOME/src/
$ export BRANCH=pu
$ git clone --branch $BRANCH git://github.com/inveniosoftware/invenio.git
We recommend to work using
`virtual environments <http://www.virtualenv.org/>`_ so packages are installed
locally and it will make your live easier. ``(invenio)$`` tells your that the
*invenio* environment is the active one.
.. code-block:: console
$ mkvirtualenv invenio
(invenio)$ # we are in the invenio environment now and
(invenio)$ # can leave it using the deactivate command.
(invenio)$ deactivate
$ # Now join it back, recreating it would fail.
$ workon invenio
(invenio)$ # That's all there is to know about it.
Let's install Invenio in the environment just created.
.. code-block:: console
(invenio)$ cdvirtualenv
(invenio)$ mkdir src; cd src
(invenio)$ git-new-workdir $HOME/src/invenio/ invenio $BRANCH
(invenio)$ cd invenio
Installing Invenio.
.. code-block:: console
(invenio)$ pip install -r requirements.txt
Some modules may require specific dependencies listed as ``extras``. Pick the
ones you need. E.g. to add images support, we can do as follow:
.. code-block:: console
(invenio)$ pip install -e .[img]
Compiling the translations.
.. code-block:: console
(invenio)$ pybabel compile -fd invenio/base/translations/
Installing the npm dependencies and the external JavaScript and CSS libraries.
.. FIXME
bower / grunt / inveniomanage collect should be run after the demosite has
been installed and only there.
.. code-block:: console
(invenio)$ npm install
(invenio)$ bower install
``grunt`` and ``inveniomanage collect`` will create the static folder with all
the required assets (JavaScript, CSS and images) from each module static folder
and bower.
.. code-block:: console
(invenio)$ grunt
(invenio)$ inveniomanage collect
3.2. Configuration
~~~~~~~~~~~~~~~~~~
Generate the secret key for your installation.
.. code-block:: console
(invenio)$ inveniomanage config create secret-key
If you are planning to develop locally in multiple environments please run
the following commands.
.. code-block:: console
(invenio)$ inveniomanage config set CFG_EMAIL_BACKEND flask.ext.email.backends.console.Mail
(invenio)$ inveniomanage config set CFG_BIBSCHED_PROCESS_USER $USER
(invenio)$ inveniomanage config set CFG_DATABASE_NAME $BRANCH
(invenio)$ inveniomanage config set CFG_DATABASE_USER $BRANCH
(invenio)$ inveniomanage config set CFG_SITE_URL http://0.0.0.0:4000
(invenio)$ inveniomanage config set CFG_SITE_SECURE_URL http://0.0.0.0:4000
Assets in non-development mode may be combined and minified using various
filters (see :ref:`ext_assets`). We need to set the path to the binaries if
they are not in the environment ``$PATH`` already.
.. code-block:: console
# Global installation
$ sudo su -c "npm install -g less clean-css requirejs uglify-js"
or
# Local installation
(invenio)$ inveniomanage config set LESS_BIN `find $PWD/node_modules -iname lessc | head -1`
(invenio)$ inveniomanage config set CLEANCSS_BIN `find $PWD/node_modules -iname cleancss | head -1`
(invenio)$ inveniomanage config set REQUIREJS_BIN `find $PWD/node_modules -iname r.js | head -1`
(invenio)$ inveniomanage config set UGLIFYJS_BIN `find $PWD/node_modules -iname uglifyjs | head -1`
Invenio comes with default demo site configuration examples that you can use
for quick start.
.. code-block:: console
(invenio)$ cd $HOME/src/
(invenio)$ git clone --branch $BRANCH git://github.com/inveniosoftware/invenio-demosite.git
(invenio)$ cdvirtualenv src
(invenio)$ git-new-workdir ~/src/invenio-demosite/ invenio-demosite $BRANCH
(invenio)$ cd invenio-demosite
(invenio)$ pip install -r requirements.txt --exists-action i
3.3. Development
~~~~~~~~~~~~~~~~
Once you have everything installed you can create database and populate it
with demo records.
.. code-block:: console
(invenio)$ inveniomanage database init --user=root --password=$MYSQL_ROOT --yes-i-know
(invenio)$ inveniomanage database create
(invenio)$ inveniomanage demosite create --packages=invenio_demosite.base
Now you should be able to run the development server. Invenio uses
`Celery <http://www.celeryproject.org/>`_ and `Redis <http://redis.io/>`_
which must be running alongside with the web server.
.. code-block:: console
$ # make sure that redis is running
$ sudo service redis-server status
redis-server is running
$ # or start it with start
$ sudo service redis-start start
$ # launch celery
$ workon invenio
(invenio)$ celeryd -E -A invenio.celery.celery --workdir=$VIRTUAL_ENV
$ # in a new terminal
$ workon invenio
(invenio)$ inveniomanage runserver
* Running on http://0.0.0.0:4000/
* Restarting with reloader
**Troubleshooting:** As a developer, you may want to use the provided
``Procfile`` with `honcho <https://pypi.python.org/pypi/honcho>`_. It
starts all the services at once with nice colors. Be default, it also runs
`flower <https://pypi.python.org/pypi/flower>`_ which offers a web interface
to monitor the *Celery* tasks.
.. code-block:: console
(invenio)$ pip install flower
When you have the servers running, it is possible to upload the demo records.
.. code-block:: console
$ # in a new terminal
$ workon invenio
(invenio)$ inveniomanage demosite populate --packages=invenio_demosite.base
And you may now open your favourite web browser on
`http://0.0.0.0:4000/ <http://0.0.0.0:4000/>`_
Optionally, if you are using Bash shell completion, then you may want to
register python argcomplete for inveniomanage.
.. code-block:: bash
eval "$(register-python-argcomplete inveniomanage)"
4. Final words
