Install Guide

1. I use RVM - Ruby Version Manager, it’s great tool to manage ruby projects, installing this tool is recommended. Look at content of .ruby-version file

2. Clone, bundle gems, install some seeds

   git clone repo
   rvm .ruby-version
   gem install bundle && bundle install

3. Set Postgresql databases omckonrails-dev, omckonrails-test, migrate and seed some data, though seed data is not available at the moment [ source, bash] rake db:setup db:migrate db:seed #optional

4. Set Environment Variables that were listed earlier with creating and editing keys in config/application.yml file

   cp config/application.yml.example config/application.yml

5. Run some tests

   rspec

6. You are done! puma

Advanced setup

• Compile Nginx with RTMP module under user nginx with base directory /opt/nginx (this is optional)

mkdir src
wget -nc -O src/nginx-1.11.3.tar.gz http://nginx.org/download/nginx-1.11.3.tar.gz
wget -nc -O src/v1.1.8.tar.gz https://github.com/arut/nginx-rtmp-module/archive/1.1.8.tar.gz

cd src
tar xf nginx-1.11.3.tar.gz
tar xf v1.1.8.tar.gz

cd nginx-$NGINX_VERSION

./configure --add-module=$WORKSPACE/src/nginx-rtmp-module-1.1.8 --prefix=/opt/nginx

make
make install

• Edit nginx.conf

    user  nginx;
    worker_processes  1;

    events {
        worker_connections  1024;
    }

    error_log  /opt/nginx/logs/error.log warn;
    pid /opt/nginx/logs/nginx.pid;

    rtmp {

        server {

            listen 1935;

            # DASH
            application dashlive {
                live on;
                dash on;
                dash_path /tmp/dash/live;

            }

            location /stat.xsl {

                add_header Access-Control-Allow-Origin *;
                root /tmp;
                add_header Cache-Control no-cache;
            }
        }
    }

• Create directories in /tmp

  mkdir -p /tmp/hls/hdgames/mobile
  mkdir -p /tmp/dash/hdgames/mobile
  mkdir /tmp/rec
  mkdir /tmp/stat

• start nginx

  /opt/nginx/sbin/nginx
