capistranoのデプロイに失敗する。

Question

(初心者向け）vpsを契約して、Capistrano3でRailsアプリをデプロイするまで その2 ローカル設定編 - Qiitaを参考にさせていただき、アプリケーションのデプロイまで完了しました。

アプリを作る過程で何回かcapistaranoで自動デプロイできていたのですが、

$ bundle exec cap production deploy

をしたところ、ある日突然デプロイができなくなってしまいました。

エラー分でいろいろ調べたりしているのですが、なかなか見当がつかず....
エラーについて知見のある方いらっしゃいましたら、解決策をご教示いただけないでしょうか。　何卒よろしくお願いいたします。

Answer 1

そのcommnadは動いている unicorn を停止させるためのものです。
しかし実際は動いていないために失敗しています。
ん〜〜〜〜　どうするかな。
kill -s USR2 $(< /var/www/{アプリ名}/current/tmp/pids/unicorn.pid) || echo is allredy stoped

とでもするのかな。

ご回答いただきありがとうございます。
こちらはVPS上で実行すれば良い認識でしょうか??

補足：
$ kill -s USR2 $(< /var/www/{アプリ名}/current/tmp/pids/unicorn.pid) || echo is allredy stoped
と入力してみたところ、
-bash: kill: (5943) - そのようなプロセスはありません
と返されました。
