[本番環境]Railsの起動がうまくいかないときのless log/production.logの見方

###本番環境
EC2
Unicorn
Nginx1

##現状

Rails起動のため
ターミナルで

RAILS_SERVE_STATIC_FILES=1 unicorn_rails -c config/unicorn.rb -E production -D

を入力し起動を試みますが

master failed to start, check stderr log for details

このようにエラーが出ます
なのでログを確認

less log/production.log

このようにエラーがでいますがどこをみたら良いかがわかりません。
