【Ruby on Rails】springを再起動する

Last updated at Posted at 2017-07-03

springとは

今回はspring再起動の方法の紹介がメインなため詳細については割愛します。Railsアプリケーションのプリローダー
開発中に何度も実行するようなrailsなどのコマンドを素早く実行することができるようになる。

再起動する

初めに、springが起動しているのを確認する。

lime:sample_app residenti$ bin/spring status
Spring is running:

25683 spring server | sample_app | started 26 mins ago
25684 spring app    | sample_app | started 26 mins ago | development mode

次に、springを停止する。
念のため、ちゃんと止まっているのかを確認。

lime:sample_app residenti$ bin/spring stop
Spring stopped.

lime:sample_app residenti$ bin/spring status
Spring is not running.

最後に、springを起動し、動いていることが確認できればOK。

lime:sample_app residenti$ bundle exec rails c
Running via Spring preloader in process 26080
Loading development environment (Rails 5.0.3)
Cannot read termcap database;
using dumb terminal settings.
irb(main):001:0> exit

lime:sample_app residenti$ bin/spring status
Spring is running:

26067 spring server | sample_app | started 14 secs ago
26068 spring app    | sample_app | started 14 secs ago | development mode
