17).rs0配置：三台机器顺序启动mongod的服务:

[hadoop@bgs-5p173-wangwenting opt]$ mongod --config /opt/mongodb/conf/rs0.conf
[hadoop@bgs-5p174-wangwenting opt]$ mongod --config /opt/mongodb/conf/rs0.conf
[hadoop@bgs-5p175-wangwenting opt]$ mongod --config /opt/mongodb/conf/rs0.conf

18).在baseline01上执行连接到mongod实例:

[hadoop@bgs-5p173-wangwenting opt]$ mongo 172.24.5.173:27017
连接成功后执行
>rs0conf = {
_id: "rs0",
members: [
{
_id: 0,
host: "172.24.5.173:27017"
}
]
}
>rs.initiate( rs0conf )
>rs.add("172.24.5.174:27017")
>rs.add("172.24.5.175:27017")
>rs.status()  //半分钟后执行该命令，若出现一主两从则说明rs0配置成功

rs1配置：
三台机器顺序启动mongod的服务:

[hadoop@bgs-5p173-wangwenting opt]$ mongod --config /opt/mongodb/conf/rs1.conf
[hadoop@bgs-5p174-wangwenting opt]$ mongod --config /opt/mongodb/conf/rs1.conf
[hadoop@bgs-5p175-wangwenting opt]$ mongod --config /opt/mongodb/conf/rs1.conf

在bgs-5p173-wangwenting上执行连接到mongod实例:

[hadoop@bgs-5p173-wangwenting opt]$ mongo 172.24.5.173:27018
>rs1conf = {
_id: "rs1",
members: [
{
_id: 0,
host: "172.24.5.173:27018"
}
]
}
>rs.initiate( rs1conf )
>rs.add("172.24.5.174:27018")
>rs.add("172.24.5.175:27018")
>rs.status()   //半分钟后执行该命令，若出现一主两从则说明rs1配置成功

19).三台机器分别启动配置服务器：

[hadoop@bgs-5p173-wangwenting opt]$ mongod --config /opt/mongodb/conf/configsvr.conf
[hadoop@bgs-5p174-wangwenting opt]$ mongod --config /opt/mongodb/conf/configsvr.conf
[hadoop@bgs-5p175-wangwenting opt]$ mongod --config /opt/mongodb/conf/configsvr.conf

20).三台机器分别启动mongos路由：

[hadoop@bgs-5p173-wangwenting opt]$ mongos --config /opt/mongodb/conf/mongos.conf
[hadoop@bgs-5p174-wangwenting opt]$ mongos --config /opt/mongodb/conf/mongos.conf
[hadoop@bgs-5p175-wangwenting opt]$ mongos --config /opt/mongodb/conf/mongos.conf

21).在172.24.5.173上连接到mongos：

[hadoop@bgs-5p175-wangwenting opt]$ mongo 172.24.5.173:27000

22).切换到admin数据库，添加分片：

mongos> use admin
mongos> db.runCommand({addshard:"rs0/172.24.5.173:27017,172.24.5.174:27017,172.24.5.175:27017"})
mongos> db.runCommand({addshard:"rs1/172.24.5.173:27018,172.24.5.174:27018,172.24.5.175:27018"})

23.查看分片状态：

mongos>db.runCommand({listshards:1})

24).为testdb数据库启动分片：

mongos>db.runCommand({enablesharding:"testdb"})
mongos>db.runCommand({shardcollection:"testdb.test_table",key:{id:1}})

25).测试插入数据:

mongos>use testdb
mongos>for(var i = 1; i <= 50000; i++) db.test_table.insert( { "id":i, "name":"str"+i, "date":new Date() } )
WriteResult({ "nInserted" : 1 })
mongos>db.test_table.stats()
查看分片状态，若rs0和rs1上分别有数据，说明部署成功
