rjbをつかったRailsのプロジェクトをcapistranoでawsにデプロイする際にGem Load Error is: can't create Java VMが発生する

Question

railsプロジェクトでkuromoji-rubyのラッパーのzipangをインストールし、capistranoでamazon linuxにデプロイする時に以下のエラーが発生しました。

linuxのirb上でkuromoji-rubyやzipangをrequireすることができ、rubyのコードを動かすことはできます。
また、amazon linux上で$JAVA_HOMEは設定してあります。
ローカル環境(Mac)では正常に動作します。

Capfile

  after :restart, :clear_cache do

end

環境 (リモートとローカルで一致)

ruby 2.5.1
rails 5.2.1

ローカル環境
java -version

java version "1.8.0_162"
Java(TM) SE Runtime Environment (build 1.8.0_162-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.162-b12, mixed mode)

リモート環境
java -version

java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)

解決法をお教えいただけると幸いです。

Answer 1

capistranoから入ったユーザーでは$JAVA_HOMEが通っていませんでした。

deploy.rb

set :default_env, {"JAVA_HOME" => "/usr/java/jdk1.8.0_181-amd64"}

で解決しました。
