Installing the OpenQuake Engine on RedHat Linux and clones

This documentation explains how to install the OpenQuake Engine on RHEL 7 and its clones (CentOS, Scientific Linux) via EPEL. GEM provides preliminary support and binary RPMs for unstable (nightly builds) and stable releases.

Dependencies

Dependencies

The following dependencies are required. They will be installed automatically by the oq-engine package:

sudo python-amqp python-celery numpy scipy python-shapely python-psycopg2 python-django python-setuptools python-psutil python-mock python-futures rabbitmq-server postgresql-server postgis

Install the OpenQuake Engine

Before installing the OpenQuake Engine you need to add EPEL and the OpenQuake Packages COPR YUM repo:

Add EPEL repositories

$ sudo yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

Unstable releases and nightly builds

$ curl -sL https://copr.fedoraproject.org/coprs/gem/openquake/repo/epel-7/gem-openquake-epel-7.repo | sudo tee /etc/yum.repos.d/gem-openquake-epel-7.repo

The full list of supported repos is available on COPR: https://copr.fedoraproject.org/coprs/gem/openquake/

Stable releases (starting from OpenQuake Engine 1.5)

$ curl -sL https://copr.fedoraproject.org/coprs/gem/openquake-stable/repo/epel-7/gem-openquake-stable-epel-7.repo | sudo tee /etc/yum.repos.d/gem-openquake-stable-epel-7.repo

Now it's possible to install the OpenQuake Engine using YUM:

$ sudo yum install python-oq-engine

Post-installation tasks

PostgreSQL initialization

$ sudo postgresql-setup initdb

Open /var/lib/pgsql/data/pg_hba.conf file and add on top of the file these lines

## localhost in IPv4
host   openquake2   oq_admin        127.0.0.1/32     md5
host   openquake2   oq_job_init     127.0.0.1/32     md5
## localhost in IPv6
host   openquake2   oq_admin        ::1/128       md5
host   openquake2   oq_job_init     ::1/128       md5

Then restart PostgreSQL

$ sudo service postgresql restart

Bootstrap the DB

$ sudo -u postgres oq_create_db
$ oq-engine --upgrade-db

A previously installed database can be removed running the dropdb tool

sudo -u postgres dropdb openquake2

Run a demo

$ oq-engine --rh=/usr/share/openquake/risklib/demos/hazard/AreaSourceClassicalPSHA/job.ini

More commands

For a list of additional commands, type oq-engine --help.

Uninstall the OpenQuake Engine

$ sudo yum erase python-oq-*

If you want to remove all the dependencies installed by the OpenQuake Engine, you need to have a yum plugin called yum-plugin-remove-with-leaves first and then use the --remove-leaves yum's flag:

$ sudo yum install yum-plugin-remove-with-leaves
$ sudo yum erase --remove-leaves python-oq-*

Reset the database and drop the datastore

You can reset the OpenQuake Engine to start from a fresh installation:

oq_reset_db

This script will remove the database and the users datastore, then it will create a fresh new setup.

To run the script without interaction the flag --yes can be used. To just drop all the data without recreating the database the flag --skip-new can be used.
