ローカルサーバーの止め方

Question

###わからないこと
toy_appというアプリをつくってそこで

$ rails generate scaffold User name:string email:string

を打ちました。

そして

rails s -b 0.0.0.0

を打ってサーバを立ち上げようとすると

=> Booting Puma
=> Rails 5.0.1 application starting in development on http://0.0.0.0:3000
=> Run `rails server -h` for more startup options
Puma starting in single mode...
* Version 3.7.0 (ruby 2.3.1-p112), codename: Snowy Sagebrush
* Min threads: 5, max threads: 5
* Environment: development

というエラーがでましたが、ページにアクセスしてみると別のアプリであるmygameが開いていました。

mygameに移動して

rails s -b 0.0.0.0

を打つと、

=> Booting Puma
=> Rails 5.0.1 application starting in development on http://0.0.0.0:3000
=> Run `rails server -h` for more startup options
A server is already running. Check /home/vagrant/workspace/mygame/tmp/pids/server.pid.
Exiting

とエラーが出ました。

再起動してみても同じでした。

ローカルサーバーを止めようと c + Ctrlキー を押してみても止まらないみたいです。

toy_appをブラウザで見てみたいので、解決方法を教えて下さるとありがたいです。

Answer 1

ps aux | grep rails して表示されたプロセス番号に対して
sudo kill -9 プロセス番号 とすれば強制的に止めることができると思います
