a) Install rbenv

# Check out rbenv into ~/.rbenv.
git clone https://github.com/sstephenson/rbenv.git ~/.rbenv

# Add ~/.rbenv/bin to your $PATH for access to the rbenv command-line utility.
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile 
# Ubuntu Desktop note: Modify your ~/.bashrc instead of ~/.bash_profile.

echo 'eval "$(rbenv init -)"' >> ~/.bash_profile


# Restart your shell so that PATH changes take effect. (Opening a new terminal tab will usually do it.) 
# Now check if rbenv was set up -
type rbenv
#=> "rbenv is a function"

b) Install rbenv-build

git clone https://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build

cd /opt/ejabberd-15.07/bin
cp ejabberd.init /etc/init.d/ejabberd

/etc/init.d/ejabberd start

1. Change the config settings. Config file can be found in your ejabberd directory under conf (ex - /opt/ejabberd-15.07/conf/ejabberd.yml)

Change “register:” (around line 481)

  register: 
    all: allow
    registration_timeout: infinity

Change “registration_timeout:” (around line 494)

registration_timeout: infinity //(yaml file level)

Enable “mod_ping”

mod_ping:
    send_pings: true
    ping_interval: 250
    timeout_action: none

2. Start/Restart ejabberd

3. Create a shared roster for every one.

4. Add a host entry for the IP pointing to the URL.

The Application uses bundler gem to manage the gem dependencies. Install the bundler gem first.

sudo gem install bundler

Once the bundler gem is installed, from the application directory (eg: /deploy/crossbow/current), run

bundle install

This would install all the necessary gems required by the application.

bundle install will end with this message:

Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.

Modify the database.yml file to reflect proper DB settings in development and test section and then run following rake task to create all the databases.

bundle exec rake db:create:all

Once the DBs are created run the migrations to create necessary tables using following command.

bundle exec rake db:migrate
bundle exec rake db:migrate RAILS_ENV=test

Run rake db:seed to create the default company and related data (This is just one time task)

bundle exec rake db:seed

The default company will be created with name 'Performexa' and subdomain as 'default'. No subdomain in url will refer to default company. e.g. http://dev01.performexa.com will take default company as a context. An admin user for the default company will also be created. The username for admin user is 'admin@performexa.com' and password is 'pforperformance'.
