配置Replica Sets

配置分片1 在172.16.0.115上配置

[root@mongodb115 ~]# /home/mongodb/bin/mongo --port 11731

MongoDB shell version: 2.4.7

connecting to: 127.0.0.1:11731/test

>config={_id:'shard1',members:[{_id:0,host:'172.16.0.115:11731' ,priority:2},{_id:1,host:'172.16.0.114:11731'},{_id:2,host:'172.16.0.103:11731',arbiterOnly:true}]}

rs.initiate(config)

配置分片2 在172.16.0.114上配置

[root@mongodb114 ~]# /home/mongodb/bin/mongo --port 11732

MongoDB shell version: 2.4.7

connecting to: 127.0.0.1:11732/test

>config={_id:'shard2',members:[{_id:0,host:'172.16.0.115:11732',arbiterOnly:true},{_id:1,host:'172.16.0.114:11732',priority:2},{_id:2,host:'172.16.0.103:11732' }]}

rs.initiate(config)

配置分片3 在172.16.0.103上配置 members里面的优先级priority值高的为主节点，对于仲裁点一定要加上arbiterOnly:true

[root@mongodb103 ~]# /home/mongodb/bin/mongo --port 11733

MongoDB shell version: 2.4.7

connecting to: 127.0.0.1:11733/test

>config={_id:'shard3',members:[{_id:0,host:'172.16.0.115:11733'},{_id:1,host:'172.16.0.114:11733',arbiterOnly:true },{_id:2,host:'172.16.0.103:11733',priority:2 }]}

[root@mongodb115 ~]# /home/mongodb/bin/mongo --port 60000

MongoDB shell version: 2.4.7

connecting to: 127.0.0.1:60000/test

mongos> use admin

switched to db admin

mongos>db.runCommand({addshard:"shard1/172.16.0.115:11731, 172.16.0.114:11731, 172.16.0.103:11731"})

mongos>db.runCommand({addshard:"shard2/172.16.0.115:11732, 172.16.0.114:11732, 172.16.0.103:11732"})

mongos> db.runCommand({addshard:"shard3/172.16.0.115:11733, 172.16.0.114:11733, 172.16.0.103:11733"})

接下来激活分片，如下面的代码所示： 采用hash分片

db.runCommand({enablesharding:"test"})

db.runCommand({shardcollection:"test.users",key:{id:"hashed"}})

强调服务时间必须要同步，否则有问题
