Zenodo depends on PostgreSQL, Elasticsearch 2.x, Redis and RabbitMQ.
If you are only interested in running Zenodo locally, follow the Docker installation guide below. If you plan to eventually develop Zenodo code continue further to Development installation to find out how to set up the local instance for easy code development.
For this guide you will need to install docker along with the docker-compose tool.
Docker installation is not necessary, although highly recommended.
If you can't use docker you can run Zenodo and all of the required services
directly in your system. Take a look at
docker-compose.yml
file to find out what is required and how the configuration looks like.
For development you will need to set-up and configure
four services: PostgreSQL (db
), Elasticsearch (es
),
Redis (cache
) and RabbitMQ (mq
).
The easiest way to run Zenodo locally is to use the provided docker-compose
configuration containing full Zenodo stack. First checkout the source code,
build all docker images and boot them up using docker-compose
:
$ cd ~/src/
$ git clone https://github.com/zenodo/zenodo.git
$ cd ~/src/zenodo
$ git checkout master
$ docker-compose -f docker-compose.full.yml build
$ docker-compose -f docker-compose.full.yml up -d
Note
For the purpose of this guide we will assume that all repositories are
checked into ~/src/
directory.
Keep the session with the docker-compose above alive, and in a new shell run the init script which creates the database tables, search indexes and some data fixtures:
$ cd ~/src/zenodo
$ docker-compose -f docker-compose.full.yml run --rm web bash /code/zenodo/scripts/init.sh
Now visit the following URL in your browser:
https://<docker ip>
Note
If you're running docker on Linux or newer Mac OS X systems,
the <docker ip>
is usually the localhost. For older Mac OS X and
Windows systems running docker through docker-machine
, you can find
the IP with
$ docker-machine ip <machine-name>
You can use the following web interface to inspect Elasticsearch and RabbitMQ:
- Elasticsearch: http://<docker ip>:9200/_plugin/hq/
- RabbitMQ: http://<docker ip>:15672/ (guest/guest)
- HAProxy: http://<docker ip>:8080/ (guest/guest)
Also the following ports are exposed on the Docker host:
80
: HAProxy81
: Nginx443
: HAProxy444
: Nginx5000
: Zenodo5432
: PostgreSQL5672
: RabbitMQ6379
: Redis8080
: HAProxy stats9200
: Elasticsearch9300
: Elasticsearch15672
: RabbitMQ management console
For the development setup we will reuse the docker-compose.yml
file from
the previous section to run only the essential Zenodo services (PostgreSQL,
ElasticSearch, Redis, etc.) and run the application code and Celery worker in
our virtualenv - you will want to have easy access to the code and the virtual
environment in which it will be installed.
Note
Since Docker will be mapping the services to the default system
ports on localhost
, make sure you are not running PostgreSQL,
Redis, RabbitMQ or Elasticsearch on those ports in your system.
Similarly to how we previously ran docker-compose -f docker-compose.full.yml
up -d
to run a "full-stack" version of Zenodo, this time we run only
four Docker containers with PostgreSQL, ElasticSearch, Redis, and RabbitMQ:
# NOTE: The "-d" flag runs the containers in the background
$ docker-compose up -d
Now, create a new Python virtual environment using virtualenvwrapper, in which we will install the Zenodo application code and its dependencies:
$ mkvirtualenv -p python2.7 zenodo
(zenodo)$
Note
Zenodo works on both on Python 2.7 and 3.5+. However in case you need to use the XRootD storage interface, you will need Python 2.7 as the underlying libraries don't support Python 3.5+ yet.
Next, install Zenodo and code the dependencies:
(zenodo)$ cd ~/src/zenodo
(zenodo)$ pip install -r requirements.txt
(zenodo)$ pip install -e ".[all]"
Next, we need to build the assets for the Zenodo application.
To compile Zenodo assets we will need to install:
- NodeJS 7.4 and NPM 4.0.5
- Asset-building dependencies: SASS 3.8.0, CleanCSS 3.4.19, UglifyJS 2.7.3 and RequireJS 2.2.0
You can install NodeJS, NPM and other dependencies using NVM (Node Version
Manager), which is similar to Python's pyenv
. To do that, you need to first
install NVM from https://github.com/creationix/nvm.
Once NVM is installed, set it to use NodeJS version 7.4:
(zenodo)$ nvm install 7.4
(zenodo)$ nvm use 7.4
Now using node v7.4.0 (npm v4.0.5)
Optionally, if you plan on working for a longer time with Node v7.4, you can
also set it as the default version, to avoid having to run nvm use ...
every time:
(zenodo)$ nvm alias default 7.4
Install the npm requirements:
(zenodo)$ ./scripts/setup-npm.sh
The packages will be installed in your local user's NVM environment.
After you've installed the NPM packages, you can finally download and build the frontend assets for Zenodo, by running the following script:
(zenodo)$ ./scripts/setup-assets.sh
To run Zenodo locally, you will need to have some services running on your machine. At minimum you must have PostgreSQL, Elasticsearch 7.x, Redis and RabbitMQ.
To run only the essential services using Docker, execute the following:
$ cd ~/src/zenodo
$ docker-compose up -d
This should bring up four docker nodes with PostgreSQL (db), Elasticsearch (es), RabbitMQ (mq), and Redis (cache). Keep this shell session alive.
Now that the services are running, it's time to initialize the Zenodo database and the ElasticSearch indexes.
Create the database, ElasticSearch indexes, messages queues and various fixtures for licenses, grants, communities and users in a new shell session:
$ cd ~/src/zenodo
$ workon zenodo
(zenodo)$ ./scripts/init.sh
Let's also run the Celery worker on a different shell session:
$ cd ~/src/zenodo
$ workon zenodo
(zenodo)$ celery worker -A zenodo.celery -l INFO --purge
Next, let's load some external data (only licenses for the time being). Loading of this demo data is done asynchronously with Celery, but depends on internet access since it involves harvesting external OAI-PMH or REST APIs.
Make sure you keep the session with Celery worker alive. Launch the data loading commands in a separate shell:
$ cd ~/src/zenodo
$ workon zenodo
(zenodo)$ zenodo opendefinition loadlicenses -s opendefinition
(zenodo)$ zenodo opendefinition loadlicenses -s spdx
(zenodo)$ ./scripts/index.sh
Finally, run the Zenodo development server in debug mode. You can do that by setting up the environment flag:
(zenodo)$ export FLASK_DEBUG=True
(zenodo)$ zenodo run
If you go to http://localhost:5000, you should see an instance of Zenodo, similar to the production instance at https://zenodo.org.
In order for the DOI badges to work you must have the Cairo SVG library and the DejaVu Sans font installed on your system. Please see Invenio-Formatter for details.
