MySQL Clusterの良いところの一つに、Rolling Upgradeが可能なので、
サービスを停止せずに、MySQL Clusterのアップグレードが可能な部分があると思います。
やはり、アップグレードにサービス停止を伴うと、インフラ管理者もサービス担当者と
メンテナンス時間の調整をしなければならず、なかなか対応がが難しいと思います。
アップグレードには、MCM（MySQL Cluster Manager)というCommercial版のツールを使えば、
コマンド一つでアップグレード可能ですが、今回はマニュアルで一つ一つアップグレードしています。
MySQL Cluster Managerは、基本的な管理ダスクを自動化することによって、
MySQL データベースの作成と管理を簡易化します。

■ 現状の構成確認
本番環境ではお勧めしませんが、デモ環境なので2台のサーバー上に共存して構成しています。

[root@cluster74_01 mysql]# /usr/local/mysql/bin/ndb_mgmd -f /usr/local/mysql/mysql-cluster/ndb-config.ini MySQL Cluster Management Server mysql-5.6.24 ndb-7.4.6 [root@cluster74_01 mysql]# /usr/local/mysql/bin/ndbd --connect-string=192.168.56.114 --nostart 2015-05-14 02:19:06 [ndbd] INFO -- Angel connected to '192.168.56.114:1186' 2015-05-14 02:19:06 [ndbd] INFO -- Angel allocated nodeid: 1 [root@cluster74_01 mysql]# /usr/local/mysql/bin/mysqld_safe & [1] 5066 [root@cluster74_01 mysql]# 150514 02:19:17 mysqld_safe Logging to '/usr/local/mysql/data/cluster74_01.err'. 150514 02:19:17 mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data [root@cluster74_01 mysql]#
全ノードのMySQLのバイナリーが同じバージョンになっている事を確認
– STOPしているノードをSTARTコマンドで開始

基本動作確認し、ログを見てエラーが無い事を確認して終了
メモ: 本番では、arbitratorの設定をもう少し明確に設定しておく。
