Instalação de sistema desenvolvido em ruby no ambiente de produção

1. Liberar execucao no home:

    mount -o remount,rw,exec /tmp

2. Instalar dependencias

    sudo apt-get install -y build-essential zlib1g-dev libyaml-dev libssl-dev libgdbm-dev libreadline-dev libncurses5-dev libffi-dev curl openssh-server checkinstall libxml2-dev libxslt-dev libcurl4-openssl-dev libicu-dev logrotate python-docutils pkg-config cmake libpq-dev git

3. Instalar o RVM

    curl -sSL https://get.rvm.io | bash
    source /home/suez/.rvm/scripts/rvm

4. Configurar variaveis de ambiente git

    sudo nano ~/.bash_profile

    Inserir na ultima linha: export GIT_SSL_NO_VERIFY=1

        source ~/.bash_profile

5. Clonar a aplicacao no /home/suez

    git clone https://gitlab.ifb.edu.br/cdds-ifb/jifb.git

6. Mover a aplicacao para /opt

    sudo mv jifb /opt

7. Instalar passenger

    - Seguir instrucoes do site: https://www.phusionpassenger.com/library/install/nginx/install/oss/stretch/

8. Configuracao nginx

    Criar arquivo /etc/nginx/sites-available/jifb.hom.ifb.local
    server {

        listen 80;
        server_name jifb.hom.ifb.local;
        passenger_enabled on;
        root /opt/jifb/public;

    }

    sudo ln -s /etc/nginx/sites-available/jifb.hom.ifb.local /etc/nginx/sites-enabled/jifb.hom.ifb.local

9. Configurar gems da aplicacao

    - Criar o arquivo config/setup_load_paths.rb
    if ENV['MY_RUBY_HOME'] && ENV['MY_RUBY_HOME'].include?('rvm')

        begin

            gems_path = ENV['MY_RUBY_HOME'].split(/@/)[0].sub(/rubies/,'gems')
            ENV['GEM_PATH'] = "#{gems_path}:#{gems_path}@global"
            require 'rvm'
            RVM.use_from_path! File.dirname(File.dirname(FILE))
            rescue LoadError
            raise "RVM gem is currently unavailable."

        end

    end

        If you're not using Bundler at all, remove lines bellow
        ENV['BUNDLE_GEMFILE'] = File.expand_path('../Gemfile', File.dirname(FILE))
        require 'bundler/setup'

    - Criar o arquivo .ruby-version com o codigo: 2.3.1

    - Criar o arquivo .ruby-gemset com o codigo: jifb

    - Instalar o ruby 2.3.1:
    rvm install 2.3.1

    - Sair e entrar na pasta do projeto:
    cd .

    - Instalar as gems:
    gem install bundler
    bundle install

10. Criar o arquivo config/database.yml

    production:

        adapter: postgresql
        database: jifb
        host: 10.6.2.18
        username: root
        password: ***
        encoding: utf8
        port: 5432

11. Configurar chave secreta da aplicacao:

    RAILS_ENV=production rake secret # para gerar a chave

    - Editar arquivo ~/.bash_profile

        export SECRET_KEY_BASE=<colar chave gerada>

12. Configurar a aplicacao:

    RAILS_ENV=production rake db:create && RAILS_ENV=production rake db:migrate && RAILS_ENV=production rake assets:precompile && sudo /etc/init.d/nginx restart
