生產MongoDB 分片與集群方案
【編者的話】
Mongo DB 是目前在IT行業非常流行的一種非關系型數據庫(NoSql),其靈活的數據存儲方式備受當前IT從業人員的青睞。Mongo DB很好的實現了面向對象的思想(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環境下MongoDB實現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臺服務器安裝好mongodb
安裝方法見安裝腳本。
2.Mongod 創建單個分片的副本集

①建立數據文件夾和日志文件夾
mdkir /data/{master,slave,arbiter}
mkdir /data/log/mongodb/{master,slave,arbiter} -p
②建立配置文件
- #master.conf
- dbpath=/data/master
- logpath=/data/log/mongodb/master/mongodb.log
- pidfilepath=/var/run/mongo_master.pid
- #directoryperdb=true
- logappend=true
- replSet=policydb
- port=10002
- oplogSize=10000
- fork=true
- noprealloc=true
- profile=1
- slowms=200
- #slave.conf
- dbpath=/data/slave
- logpath=/data/log/mongodb/slave/mongodb.log
- pidfilepath=/var/run/mongo_slave.pid
- #directoryperdb=true
- logappend=true
- replSet=policydb
- port=10001
- oplogSize=10000
- fork=true
- noprealloc=true
- profile=1
- slowms=200
- #arbiter.conf
- dbpath=/data/arbiter
- logpath=/data/log/mongodb/arbiter/mongodb.log
- pidfilepath=/var/run/mongo_arbiter.pid
- #directoryperdb=true
- logappend=true
- replSet=policydb
- port=10000
- oplogSize=10000
- fork=true
- noprealloc=true
- profile=1
- slowms=200
③啟動mongodb
/etc/init.d/mongodb_master start
/etc/init.d/mongodb_slave start
/etc/init.d/mongodb_arbiter start
④配置主、備、仲裁節點
主節點:
- # /usr/local/mongodb/bin/mongo 10.68.4.209:10002
- MongoDB shell version: 2.4.9
- connecting to: 10.68.4.209:10002/test
- > use admin
- switched to db admin
- >config={ _id:"policydb", members:[ {_id:0,host:'10.68.4.209:10002',priority:2}, {_id:1,host:'10.68.4.209:10001',priority:1},
- ... {_id:2,host:'10.68.4.209:10000',arbiterOnly:true}] };

2.Mongod 創建單個分片的配置服務器
① 創建配置目錄
10.68.4.209 mkdir /data/config
10.68.4.29 mkdir /data/config
10.68.4.30 mkdir /data/config
②準備配置服務器的配置文件
3個服務器的配置服務器的配置文件一致
- #config.conf
- dbpath=/data/config
- logpath=/data/log/mongodb/config/mongodb.log
- pidfilepath=/var/run/mongo_config.pid
- directoryperdb=true
- logappend=true
- port=10003
- fork=true
- configsvr=true
③啟動配置服務器
/etc/init.d/mongodb_config start
3.Mongod 創建并配置mongos和開啟分片模式
① 創建日志目錄
Mkdir -p /data/log/mongodb/mongos/
② 準備mongos的配置文件
- #mongos.conf
- logpath=/data/log/mongodb/mongos/mongodb.log
- pidfilepath=/var/run/mongo_mongos.pid
- logappend=true
- port=10004
- fork=true
- configdb=10.68.4.209:10003,10.68.4.29:10003,10.68.4.30:1000
③ 啟動mongos
/etc/init.d/mongodb_mongos start
④ 配置分片
- sh.addShard("policydb/10.68.4.209:10002")
- sh.addShard("policydb2/10.68.4.29:10002")
- sh.addShard("policydb3/10.68.4.30:10002")
- sh.enableSharding("policydb")
- db.runCommand({"shardcollection":"policydb.fullPolicyTextInfo_history", "key":{"key":1}})
- db.printShardingStatus() #查看分片狀態
- sh.status({verbose:true})
- sh.status()
