試したこと

〇server.pidファイルを削除
〇再度ターミナルを立ち上げる

補足情報（FW/ツールのバージョンなど）

rails初心者です。サーバーを立ち上げたままターミナルを閉じてしまったことが原因だと思うのですが...どなたかご教授いただければ幸いです。

エラーのログってこれで全部でしたでしょうか？エラー分の最後の方をみたいです。

すみません、切れてしまっていました...! Address already in use - bind(2) for "127.0.0.1" port 8080 (Errno::EADDRINUSE) です！

lsof -i :8080　とすると COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME ruby 7118 ec2-user 15u IPv4 23850 0t0 TCP localhost:webcache (LISTEN) ruby 7118 ec2-user 16u IPv6 23851 0t0 TCP localhost6:webcache (LISTEN) ruby 7118 ec2-user 21u IPv4 23876 0t0 TCP localhost:webcache->localhost:45004 (CLOSE_WAIT) ruby 7118 ec2-user 25u IPv4 23905 0t0 TCP localhost:webcache->localhost:45006 (CLOSE_WAIT) ec2-user:~/environment/weleve (master) $ kill -QUIT 7118 bash: kill: (7118) - No such process ここで行き詰ってしまいました..
