1，因mysql壓力需求，採用apache Ignite做快取前置，考慮不影響現有業務邏輯下，apache Ignite昨為查詢主庫，mysql不變，所以以mysql為持久層，php寫個載入啟動，mysql表比較多，手寫配置檔案不符合場景，決定用php寫啟動應用程式碼
2,配置檔案（說明：採用純快取不切實際，200多萬資料好用1G記憶體，配置持久化

3，啟動ignite
4，啟用叢集命令
/opt/tmp/apache-ignite-fabric-2.6.0-bin/bin/control.sh --activate
5，程式碼建立表，載如資料庫
6，單臺服務查詢效能遠不如單臺mysql，同樣的資料量同樣的sql，場景不同吧，不符合需求，以致詳情的沒動力貼了。
