LARP-Platform

Here is a little manual:

• Install JDK 1.8
• Install Grails
• Install PostgreSQL and create database for application
• Run grails application.

How to install and configure JDK?

Download and extract Oracle Java SE Development Kit 8 or OpenJDK 8. Then add to ~/.profile file this line:

export JAVA_HOME=<path-to-jdk>
PATH=$PATH:$JAVA_HOME/bin

You can also install JDK via standart repositories:

sudo apt-get install openjdk-8-jdk

If JDK already installed in your system there may be some problems with default comands like java and javac. They can be linked with older version of Java. To know it exactly you should execute:

update-alternatives --config java

You will see a list of paths to different versions of JDK. Then choose a number of the correct version.

If there is no correct version, you can add it by the command:

update-alternatives --install /usr/bin/java java <path-to-jdk>/bin/java 1

Then try to configure symlink again and repeat this part for javac command.

How to install and configure Grails?

Download and extract Grails from official site. Then add to ~/.profile file this line:

export GRAILS_HOME=<path-to-grails>
PATH=$PATH:$GRAILS_HOME/bin

How to install PostgreSQL and create database?

Install PostgreSQL via standart repositories:

sudo apt-get install postgresql

If there is no russian locale in your system, you should install it:

sudo locale-get ru_RU.UTF-8

Then drop and create again cluster with russian locale:

sudo pg_dropcluster --stop <version> main
sudo pg_createcluster --locale ru_RU.UTF-8 <version> main

After this manipulations PostgreSQL daemon will be down. You should start it again:

sudo service postgresql start

In /etc/postgresql//main/pg_hba.conf add rules:

local sameuser all md5
local template1 all md5

And restart daemon.

Enter in PosgreSQL console like this:

sudo -upostgres psql

And create user and database:

#!sql
CREATE USER larp_platform ENCRYPTED PASSWORD 'larp_platform';
CREATE DATABASE larp_platform OWNER 'larp_platform';

To check connection try this:

psql -Ularp_platform

How to configure database settings?

Edit file grails-app/conf/DataSource.groovy:

#!groovy
dataSource {
    ...
    username = "larp_platform"
    password = "larp_platform"
}

...
environments {
    development {
        dataSource {
            ...
            url = "jdbc:postgresql://<host>:5432/larp_platform"
        }
    }
    ...
}

How to run application?

You can run application on internal tomcat (development mode by default):

grails [-Dgrails.server.port.http=8090] [dev|test|prod] run-app

Also you can deploy war-file on tomcat manualy. To build war-file execute (production mode by default):

grails [dev|test|prod] war
