CentOS6.5下安装配置MongoDB分片集群

没什么仔细的解释，直接上配置过程，有问题的同学请看原文或百度查详细资料，有想法的同学也欢迎留言交流哈

副本集： http://www.thebigdata.cn/JieJueFangAn/12416.html
分片： http://www.thebigdata.cn/jiejueFangAn/12418.html

自己动手配置一遍后总结如下：

1.创建各个目录(config,mongos.shard1......)

2.如下

Start Mongodb :
./mongod --dbpath /usr/local/mongodbtest/single/data/

Start Master MongoDB :

./mongod -dbpath /usr/local/mongodbtest/master -master

每台机器启动副本集命令 :
./mongod --dbpath /usr/local/mongodbtest/replset/data --replSet repset

随便进一台机器配置副本集

./mongo

use admin

config = {_id:"repset",members:[{_id:0,host:"192.168.75.129:27017"},{_id:1,host:"192.168.75.130:27017"},{_id:2,host:"192.168.75.131:27017"}]}
rs.initiate(config);

正文开始

分片配置(注意：3台服务器的时间一定要相同，不然分片会失败！！！！)

1.启动配置服务器
./mongod --configsvr --dbpath /usr/local/mongodbtest/shard/config/data --port 21000 --logpath /usr/local/mongodbtest/shard/config/log/config.log --fork

2.启动mongos服务器
./mongos --configdb 192.168.75.129:21000,192.168.75.130:21000,192.168.75.131:21000 --port 20000 --logpath /usr/local/mongodbtest/shard/mongos/log/mongos.log --fork

3.配置各个分片的副本集
./mongod --shardsvr --replSet shard1 --port 22001 --dbpath /usr/local/mongodbtest/shard/shard1/data --logpath /usr/local/mongodbtest/shard/shard1/log/shard1.log --fork --nojournal --oplogSize 10

./mongod --shardsvr --replSet shard2 --port 22002 --dbpath /usr/local/mongodbtest/shard/shard2/data --logpath /usr/local/mongodbtest/shard/shard2/log/shard2.log --fork --nojournal --oplogSize 10

./mongod --shardsvr --replSet shard3 --port 22003 --dbpath /usr/local/mongodbtest/shard/shard3/data --logpath /usr/local/mongodbtest/shard/shard3/log/shard3.log --fork --nojournal --oplogSize 10

4.定义副本集配置

./mongo 127.0.0.1:22001
use admin
configshard1={_id:"shard1",host:"192.168.75.129:22001"},host:"192.168.75.130:22001"},host:"192.168.75.131:22001",arbiterOnly:true}]}
rs.initiate(configshard1);

./mongo 127.0.0.1:22002
use admin
configshard2={_id:"shard2",host:"192.168.75.129:22002"},host:"192.168.75.130:22002"},host:"192.168.75.131:22002",arbiterOnly:true}]}
rs.initiate(configshard2);

./mongo 127.0.0.1:22003
use admin
configshard3={_id:"shard3",host:"192.168.75.129:22003"},host:"192.168.75.130:22003"},host:"192.168.75.131:22003",arbiterOnly:true}]}

rs.initiate(configshard3);

备注：

arbiterOnly:true表示该节点是仲裁节点，不参数存储数据

5.串联路由服务器与分配副本集
./mongo 127.0.0.1:20000
use admin
db.runCommand({addshard:"shard1/192.168.75.129:22001,192.168.75.130:22001,192.168.75.131:22001"});

db.runCommand({addshard:"shard2/192.168.75.129:22002,192.168.75.130:22002,192.168.75.131:22002"});

db.runCommand({addshard:"shard3/192.168.75.129:22003,192.168.75.130:22003,192.168.75.131:22003"});

6.指定的数据库和集合分片生效
db.runCommand({enablesharding:"testdb"})

db.runCommand({shardcollection:"testdb.table1",key:{id:1}})

7.Spring整合MongoDB分片集群的配置：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

</mongo:mongo>

<mongo:db-factory id="mongoDbFactory" dbname="testdb" mongo-ref="mongo"/>

<bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
<constructor-arg index="0" ref="mongoDbFactory"/>
</bean>
</beans>

--------------------------------------------------------------------------------------------------------------------------------------------------------------

8.Java连接MongoDB

public class Test { public static void main(String[] args) { List<ServerAddress> addresses = new ArrayList<>(); ServerAddress ad1 = new ServerAddress("192.168.75.129",20000); ServerAddress ad2 = new ServerAddress("192.168.75.130",20000); ServerAddress ad3 = new ServerAddress("192.168.75.131",20000); addresses.add(ad1); addresses.add(ad2); addresses.add(ad3); @SuppressWarnings("resource") MongoClient client = new MongoClient(addresses); @SuppressWarnings("deprecation") DB db = client.getDB("testdb"); DBCollection coll = db.getCollection("table1"); searchAll(coll); } public static void save(DBCollection coll){ BasicDBObject basicDBObject = new BasicDBObject(); basicDBObject.append("id",100001); basicDBObject.append("testKey","testVal"); coll.save(basicDBObject); } public static void searchAll(DBCollection coll){ DBCursor dbObject = coll.find(); List<DBObject> dbObjects = dbObject.toArray(); for(DBObject dbObject2 : dbObjects){ System.out.println(dbObject2); } } }
