aws cloud9 ruby on rails migration 後にしたこと

まずは bundle install

mysql が動かない。

username: <%=ENV['C9_USER']%>
#  password: <%=ENV['C9_USER']%> 

もともとこんな感じになってたので、設定変更。
これで、 rails db:create, db:migrate ... ok

rails server を動かす IP とか若干違った

before
rails server -b $IP -p $PORT
after
rails s -b 0.0.0.0

app が error 出す

ruby の version が 変わってた。gem とか 大幅アップデートとか嫌だったので、昔のsetupでいく方針 (live app だったので)
lvm listで状況確認して
rvm install 2.3した (live 環境 2.3.x だったので)
rvm default 2.3.X
この状態で も一度 rails s -b 0.0.0.0 ...ok
