生產(chǎn)MongoDB分片與集群方案.docx

生產(chǎn)MongoDB 分片與集群方案【編者的話】Mongo DB 是目前在IT行業(yè)非常流行的一種非關(guān)系型數(shù)據(jù)庫(NoSql),其靈活的數(shù)據(jù)存儲方式備受當前IT從業(yè)人員的青睞。Mongo DB很好的實現(xiàn)了面向?qū)ο蟮乃枷?OO思想),在Mongo DB中 每一條記錄都是一個Document對象。本文介紹了一則生產(chǎn)環(huán)境下MongoDB實現(xiàn)分片與集群方案的操作實例。一、 mongodb分片與集群拓撲圖二、分片與集群的部署1.Mongodb的安裝分別在以上3臺服務(wù)器安裝好mongodb安裝方法見安裝腳本。2.Mongod
