Productive Rails application - HVboom/HowTo-DigitalOcean GitHub Wiki

Create a dedicated user

• follow the Development User instructions
• the name of the user will be the name of the application URL, like bim.hvboom.net for an application user bim

Install the application

• login into the new user account

• add export RAILS_ENV='production' to your $HOME/.profileto ensure the right environment

  • logout and login again or run the command export RAILS_ENV='production' in the current shell

• Checkout the GitLab repository of the application

  cd $HOME/RubyOnRails
  
  git clone [email protected]:<application repository>.git  # example: git clone [email protected]:HVboom/BuildingIntegrationModeling.git
  
  ln -s <application> $USER  # example: ln -s BuildingIntegrationModeling bim
  

• Prepare Bundler production settings by creating a config file $HOME/RubyOnRails/<application>/.bundler/config

  mkdir -p "$HOME/RubyOnRails/$USER/.bundle"
  touch "$HOME/RubyOnRails/$USER/.bundle/config" >/dev/null 2>&1
  if [ -w "$HOME/RubyOnRails/$USER/.bundle/config" ]
  then
    echo '---'                                 > $HOME/RubyOnRails/$USER/.bundle/config
    echo 'BUNDLE_WITHOUT: "development:test"' >> $HOME/RubyOnRails/$USER/.bundle/config
    echo 'BUNDLE_FROZEN: true'                >> $HOME/RubyOnRails/$USER/.bundle/config
    echo 'BUNDLE_PATH: "vendor/bundle"'       >> $HOME/RubyOnRails/$USER/.bundle/config
    echo 'BUNDLE_DISABLE_SHARED_GEMS: true'   >> $HOME/RubyOnRails/$USER/.bundle/config
  fi
  
  # run 'bundle install' automatically
  cd $HOME/RubyOnRails/$USER
  

Setup the Ruby On Rails application

• MySQL only: Create database user for the application user (e.g. bim) with phpMyAdmin

  images/phpMyAdmin_AddApplicationUser.png

• If you have the config/master.key file, then you are lucky - otherwise

  • Delete the file config/credentials.yml.enc
  • Create a new one with EDITOR=vim bundle exec rails credentials:edit using the content of config/credentials.yml.example

• Compile assets: NODE_ENV=production RAILS_ENV=production bundle exec rake assets:precompile

• Setup the database: RAILS_ENV=production bundle exec rake db:create db:schema:load db:seed

• Cleanup log and tmp directory: RAILS_ENV=production bundle exec rake log:clear tmp:clear

• Restart application: RAILS_ENV=production bundle exec rake restart

Update application

• Checkout new version: cd $HOME/RubyOnRails/$USER && git pull
• Update to newest Gem versions: RAILS_ENV=production bundle install
• Update to newest Node versions: yarn install --production
• Remove obsolete Gem version: RAILS_ENV=production bundle clean --force
• Compile assets: NODE_ENV=production RAILS_ENV=production bundle exec rake assets:precompile
• Setup the database: RAILS_ENV=production bundle exec rake db:migrate
• Cleanup log and tmp directory: RAILS_ENV=production bundle exec rake log:clear tmp:clear
• Restart application: RAILS_ENV=production bundle exec rake restart
