解壓mongodb檔案

主機1

[root@mongodb115 ~]# tar zxvf mongodb-linux-x86_64-2.4.7.tgz

[root@mongodb115 ~]# mv mongodb-linux-x86_64-2.4.7 /home/mongodb

主機2

[root@mongodb114 ~]# tar zxvf mongodb-linux-x86_64-2.4.7.tgz

[root@mongodb114 ~]# mv mongodb-linux-x86_64-2.4.7 /home/mongodb

主機3

[root@mongodb103 ~]# tar zxvf mongodb-linux-x86_64-2.4.7.tgz

[root@mongodb103 ~]# mv mongodb-linux-x86_64-2.4.7 /home/mongodb

啟動shard1,shard2,shard3

[root@mongodb115 ~]# /home/mongodb/bin/mongod -f /home/config/shard1_1.conf

[root@mongodb115 ~]# /home/mongodb/bin/mongod -f /home/config/shard2_1.conf

[root@mongodb115 ~]# /home/mongodb/bin/mongod -f /home/config/shard3_1.conf

[root@mongodb114 ~]# /home/mongodb/bin/mongod -f /home/config/shard1_2.conf

[root@mongodb114 ~]# /home/mongodb/bin/mongod -f /home/config/shard2_2.conf

[root@mongodb114 ~]# /home/mongodb/bin/mongod -f /home/config/shard3_2.conf

[root@mongodb103 ~]# /home/mongodb/bin/mongod -f /home/config/shard1_3.conf

[root@mongodb103 ~]# /home/mongodb/bin/mongod -f /home/config/shard2_3.conf

[root@mongodb103 ~]# /home/mongodb/bin/mongod -f /home/config/shard3_3.conf

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

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' }]}

配置分片3  在172.16.0.103上配置 members裡面的優先級priority值高的為主節點，對于仲裁點一定要加上arbiterOnly:true

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

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 }]}

啟動3台config server

[root@mongodb115 ~]# /home/mongodb/bin/mongod  -f /home/config/config.conf

[root@mongodb114 ~]# /home/mongodb/bin/mongod  -f /home/config/config.conf

[root@mongodb103 ~]# /home/mongodb/bin/mongod  -f /home/config/config.conf

啟動3台 Route Process

[root@mongodb115 ~]# /home/mongodb/bin/mongos -f /home/config/mongos.conf

[root@mongodb114 ~]# /home/mongodb/bin/mongos -f /home/config/mongos.conf

[root@mongodb103 ~]# /home/mongodb/bin/mongos -f /home/config/mongos.conf

配置shard Cluser

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

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"})

接下來激活分片，如下面的代碼所示：    采用hash分片

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

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

強調服務時間必須要同步，否則有問題
