Dependencies

Java 8 is necessary to run the REST-api server which is built on top of the Play Framework:

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

EBeans can use other data providers, but for ease we documented a default setup here with PostgreSQL 9.3 or higher:

sudo apt-get install postgresql postgresql-contrib

In order to run Play Framework, TypeSafe activator is required. Download activator from here and add it to your path. Make sure this is available on the path of the user that will run the REST server as well.

Server configuration

First, the server code has to be compiled into a production distribution.This can be executed from within the source directory:

activator dist

Next, copy the distribution to the folder where the REST server will be ran:

cp -rf target/universal/ /opt/cros

Make sure the user running the REST server has write permissions to the /logs folder. Next, create a database user and database for the REST application. This user also requires CREATE, DROP permissions on the database. This username, password and database credentials can be put into the application.conf in the conf directory.

db.default.driver=org.postgresql.Driver
db.default.url="jdbc:postgresql://localhost:5432/cros-web"
db.default.user=cros
db.default.password="password"

The server can now be started:

/opt/cros/universal/stage/bin/cros-core -Dhttp.port=9000 -DapplyEvolutions.default=true </dev/null >play.out 2>&1 &

nginx can be used as a reverse proxy in combination with the frontend. For more information, please checkout the frontend documentation.
