where to save the unicorn PIDS and sockets path as the folders gets dissappers after mina deploy rails app

Question

I have set up a server for deploying my rails app. I am not able to start unicorn service. It is giving me a failed status. I am totally new to this. So as per this tutorial https://www.digitalocean.com/community/tutorials/how-to-deploy-a-rails-app-with-unicorn-and-nginx-on-ubuntu-14-04. I created the shared folders for the socket, PIDs on the server. but I am using mina for deployment after every release my shared folder which I manually created, disappears and goes away with the old release with my unicorn files. So I created that shared folders on my local Desktop but they are not getting pushed to the server via git. So where and how should I place my unicorn pids and sockets to make it working below are my files

my unicorn.rb file

root = "/home/deployer/apps/rails_app/current"
working_directory root
pid "#{root}/shared/unicorn.pid"
stderr_path "#{root}/log/unicorn.log"
stdout_path "#{root}/log/unicorn.log"

listen "/shared/unicorn.railsapp.sock"
worker_processes 2
timeout 30

preload_app true

My /etc/init.d/unicorn_rails_app file

set -e

    USAGE="Usage: $0 <start|stop|restart|upgrade|rotate|force-stop>"

    # app settings
    USER="ggg"
    APP_NAME="rails_app"
    APP_ROOT="/home/$USER/$APP_NAME/current"
    ENV="production"

    # environment settings
    PATH="/home/$USER/.rbenv/shims:/home/$USER/.rbenv/bin:$PATH"
    CMD="cd $APP_ROOT && bundle exec unicorn -c config/unicorn.rb -E $ENV -D"
    PID="$APP_ROOT/shared/pids/unicorn.pid"
    OLD_PID="$PID.oldbin"

    # make sure the app exists
    cd $APP_ROOT || exit 1

    sig () {
      test -s "$PID" && kill -$1 `cat $PID`
    }

    oldsig () {
      test -s $OLD_PID && kill -$1 `cat $OLD_PID`
    }

    case $1 in
      start)
      sig 0 && echo >&2 "Already running" && exit 0
        echo "Starting $APP_NAME"
        su - $USER -c "$CMD"
        ;;
      stop)
        echo "Stopping $APP_NAME"
        sig QUIT && exit 0
        echo >&2 "Not running"
        ;;
      force-stop)
        echo "Force stopping $APP_NAME"
        sig TERM && exit 0
        echo >&2 "Not running"
        ;;
      restart|reload|upgrade)
        sig USR2 && echo "reloaded $APP_NAME" && exit 0
        echo >&2 "Couldn't reload, starting '$CMD' instead"
        $CMD
        ;;
      rotate)
        sig USR1 && echo rotated logs OK && exit 0
        echo >&2 "Couldn't rotate logs" && exit 1
        ;;
      *)
        echo >&2 $USAGE
        exit 1
        ;;
    esac

      queue "mkdir -p #{deploy_to}/current/tmp2/"
      queue "touch #{deploy_to}/current/tmp2/restart.txt"
    end
  end
end

I am getting this errors

Keep them in shared folder, you can create symlink to tmp folder in shared.
