RedisをCentOSにインストールして起動スクリプトを書いてみた

redis.conf

起動時にデーモン化したり、ログファイルを作ったりするように、オリジナルに変更を加えています。

起動・停止・再起動とかのスクリプト

redis-serverやredis.confの場所は環境によって違うと思うので適宜読み替えてください。

radis という名前のファイルとして保存

CentOSの起動時スクリプトとして登録

• $ chmod +x redis：上記の起動・停止・再起動スクリプトに実行権限を付与
• $ sudo mv redis /etc/rc.d/init.d/redis：起動時スクリプトとして設置
• $ sudo /etc/rc.d/init.d/redis start：起動する
• $ sudo chkconfig --add redis：起動時スクリプトに追加
• $ sudo chkconfig redis on：起動時スクリプトに登録
• $ sudo chkconfig --list redis：ランレベルを確認
