生产环境MongoDB 分片与集群 方案

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.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:

# /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 创建单个分片的配置服务器

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.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.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 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()
