MySQLデータベースサーバーmysqldの起動[失敗]

今日、Ubuntu 13.10にMySQLをインストールしましたが、非常にうまくいきました。しかし、コンピューターを再起動した後、MySQLを再起動すると失敗し、/ var / log / mysqlのログは次のようになります。

誰もがこの問題を解決するのを手伝ってくれますか、ありがとう！

ログ出力からかなり明らかなようです。 [ERROR] /usr/sbin/mysqld: unknown variable 'default-character-set=utf8'

探していると思いますcharacter-set-server。
