生产MongoDB 分片与集群方案
Mongo DB 是目前在IT行业非常流行的一种非关系型数据库(NoSql),其灵活的数据存储方式备受当前IT从业人员的青睐。Mongo DB很好的实现了面向对象的思想(OO思想),在Mongo DB中 每一条记录都是一个Document对象。本文介绍了一则生产环境下MongoDB实现分片与集群方案的操作实例。一、 mongodb分片与集群拓扑图
二、分片与集群的部署
1.Mongodb的安装
分别在以上3台服务器安装好mongodb
安装方法见安装脚本。
2.Mongod 创建单个分片的副本集
10.68.4.209
①建立数据文件夹和日志文件夹
mdkir /data/{master,slave,arbiter}
mkdir /data/log/mongodb/{master,slave,arbiter} -p
②建立配置文件
#master.confdbpath=/data/masterlogpath=/data/log/mongodb/master/mongodb.logpidfilepath=/var/run/mongo_master.pid#directoryperdb=truelogappend=truereplSet=policydbport=10002oplogSize=10000fork=truenoprealloc=trueprofile=1slowms=200#slave.confdbpath=/data/slavelogpath=/data/log/mongodb/slave/mongodb.logpidfilepath=/var/run/mongo_slave.pid#directoryperdb=truelogappend=truereplSet=policydbport=10001oplogSize=10000fork=truenoprealloc=trueprofile=1slowms=200#arbiter.confdbpath=/data/arbiterlogpath=/data/log/mongodb/arbiter/mongodb.logpidfilepath=/var/run/mongo_arbiter.pid#directoryperdb=truelogappend=truereplSet=policydbport=10000oplogSize=10000fork=truenoprealloc=trueprofile=1slowms=200 ③启动mongodb
/etc/init.d/mongodb_master start
/etc/init.d/mongodb_slave start
/etc/init.d/mongodb_arbiter start
④配置主、备、仲裁节点
主节点:

① 创建配置目录
10.68.4.209 mkdir /data/config
10.68.4.29 mkdir /data/config
10.68.4.30 mkdir /data/config
②准备配置服务器的配置文件
3个服务器的配置服务器的配置文件一致
#config.confdbpath=/data/configlogpath=/data/log/mongodb/config/mongodb.logpidfilepath=/var/run/mongo_config.piddirectoryperdb=truelogappend=trueport=10003fork=trueconfigsvr=true ③启动配置服务器
/etc/init.d/mongodb_config start
3.Mongod 创建并配置mongos和开启分片模式
① 创建日志目录
Mkdir -p /data/log/mongodb/mongos/
② 准备mongos的配置文件
#mongos.conflogpath=/data/log/mongodb/mongos/mongodb.logpidfilepath=/var/run/mongo_mongos.pidlogappend=trueport=10004fork=trueconfigdb=10.68.4.209:10003,10.68.4.29:10003,10.68.4.30:1000 ③ 启动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() #查看分片状态sh.status({verbose:true})sh.status() 3.快速创建副本集和配置服务脚本
