操作系统：redhat6.4 64位

一、在三个节点上创建如下目录，做测试的话建议确保在/目录有15G左右的剩余空间

[root@orcl ~]# mkdir -p /var/config

[root@orcl ~]# mkdir -p /var/sd1

[root@orcl ~]# mkdir -p /var/sd2

[root@orcl ~]# mkdir -p /var/sd3

二、查看配置文件

[root@orcl ~]# cat /etc/config.conf 

port=28000

dbpath=/var/config

logpath=/var/config/config.log

logappend=true

fork=true

configsvr=true

[root@orcl ~]# cat /etc/route.conf 

port=27017

configdb=192.168.1.30:28000,192.168.1.52:28000,192.168.1.108:28000

logpath=/var/log/mongos.log

logappend=true

fork=true

[root@orcl ~]# cat /etc/sd1.conf 

port = 27018

dbpath=/var/sd1

logpath =/var/sd1/shard1.log

logappend =true

shardsvr =true

replSet =set1

fork =true

[root@orcl ~]# cat /etc/sd2.conf  

port = 27019

dbpath=/var/sd2

logpath =/var/sd2/shard2.log

logappend =true

shardsvr =true

replSet =set2

fork =true

[root@orcl ~]# cat /etc/sd3.conf   

port = 27020

dbpath=/var/sd3

logpath =/var/sd3/shard1.log

logappend =true

shardsvr =true

replSet =set3

fork =true

三、在三个节点上同步时间

略

四、在三个节点上启动用config服务器

节点1

[root@orcl ~]# mongod -f /etc/config.conf 

about to fork child process, waiting until server is ready for connections.

forked process: 3472

child process started successfully, parent exiting

[root@orcl ~]# ps -ef |grep mongo

root      3472     1  1 19:15 ?        00:00:01 mongod -f /etc/config.conf

root      3499  2858  0 19:17 pts/0    00:00:00 grep mongo

[root@orcl ~]# netstat -anltp|grep 28000

root      4763     1  4 21:04 ?        00:00:12 mongod -f /etc/sd3.conf

七、配置副本集

192.168.1.30

[root@orcl ~]# mongo --port 27018

MongoDB shell version: 2.6.4

connecting to: 127.0.0.1:27018/test

> use admin

switched to db admin

> rs1={_id:"set1",members:[{_id:0,host:"192.168.1.30:27018",priority:2},{_id:1,host:"192.168.1.52:27018"},{_id:2,host:"192.168.1.108:27018",arbiterOnly:true}]}

{

        "_id" : "set1",

        "members" : [

                {

                        "_id" : 0,

                        "host" : "192.168.1.30:27018",

                        "priority" : 2

                },

                {

                        "_id" : 1,

                        "host" : "192.168.1.52:27018"

                },

                {

                        "_id" : 2,

                        "host" : "192.168.1.108:27018",

                        "arbiterOnly" : true

                }

        ]

}

> rs.initiate(rs1)

{

        "info" : "Config now saved locally.  Should come online in about a minute.",

        "ok" : 1

}

192.168.1.52

[root@orcl ~]# mongo --port 27019

MongoDB shell version: 2.6.4

connecting to: 127.0.0.1:27019/test

> use admin

switched to db admin

> rs2={_id:"set2",members:[{_id:0,host:"192.168.1.52:27019",priority:2},{_id:1,host:"192.168.1.108:27019"},{_id:2,host:"192.168.1.30:27019",arbiterOnly:true}]}

{

        "_id" : "set2",

        "members" : [

                {

                        "_id" : 0,

                        "host" : "192.168.1.52:27019",

                        "priority" : 2

                },

                {

                        "_id" : 1,

                        "host" : "192.168.1.108:27019"

                },

                {

                        "_id" : 2,

                        "host" : "192.168.1.30:27019",

                        "arbiterOnly" : true

                }

        ]

}

> rs.initiate(rs2);

{

        "info" : "Config now saved locally.  Should come online in about a minute.",

        "ok" : 1

}

192.168.1.108

[root@localhost sd3]# mongo --port 27020

MongoDB shell version: 2.6.4

connecting to: 127.0.0.1:27020/test

> use admin

switched to db admin

> rs3={_id:"set3",members:[{_id:0,host:"192.168.1.108:27020",priority:2},{_id:1,host:"192.168.1.30:27020"},{_id:2,host:"192.168.1.52:27020",arbiterOnly:true}]}

{

        "_id" : "set3",

        "members" : [

                {

                        "_id" : 0,

                        "host" : "192.168.1.108:27020",

                        "priority" : 2

                },

                {

                        "_id" : 1,

                        "host" : "192.168.1.30:27020"

                },

                {

                        "_id" : 2,

                        "host" : "192.168.1.52:27020",

                        "arbiterOnly" : true

                }

        ]

}

> rs.initiate(rs3);

{

        "info" : "Config now saved locally.  Should come online in about a minute.",

        "ok" : 1

}

八、添加分片

在三个节点上任一个节点都可以操作

192.168.1.30

[root@orcl sd3]# mongo --port 27017

MongoDB shell version: 2.6.4

connecting to: 127.0.0.1:27017/test

mongos> use admin

switched to db admin

mongos> db.runCommand({addshard:"set1/192.168.1.30:27018,192.168.1.52:27018,192.168.1.108:27018"})

{ "shardAdded" : "set1", "ok" : 1 }

mongos> db.runCommand({addshard:"set2/192.168.1.30:27019,192.168.1.52:27019,192.168.1.108:27019"})

{ "shardAdded" : "set2", "ok" : 1 }

mongos> db.runCommand({addshard:"set3/192.168.1.30:27020,192.168.1.52:27020,192.168.1.108:27020"})

{ "shardAdded" : "set3", "ok" : 1 }

九、查看分片信息

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

{

        "shards" : [

                {

                        "_id" : "set1",

                        "host" : "set1/192.168.1.30:27018,192.168.1.52:27018"

                },

                {

                        "_id" : "set2",

                        "host" : "set2/192.168.1.108:27019,192.168.1.52:27019"

                },

                {

                        "_id" : "set3",

                        "host" : "set3/192.168.1.108:27020,192.168.1.30:27020"

                }

        ],

        "ok" : 1

}

十、删除分片

mongos> db.runCommand({removeshard:"set3"})

{

        "msg" : "draining started successfully",

        "state" : "started",

        "shard" : "set3",

        "ok" : 1

}

十一、管理分片

mongos> use config

switched to db config

mongos> db.shards.find();

{ "_id" : "set1", "host" : "set1/192.168.1.30:27018,192.168.1.52:27018" }

{ "_id" : "set2", "host" : "set2/192.168.1.108:27019,192.168.1.52:27019" }

{ "_id" : "set3", "host" : "set3/192.168.1.108:27020,192.168.1.30:27020" }

十二、对要分片的库和表声明

切换到admin库

mongos> use admin      

声明test库允许分片

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

{ "ok" : 1 } 

声明users表要分片  

mongos> db.runCommand({shardcollection:"test.lineqi",key:{id:"hashed"}})

{ "collectionsharded" : "test.lineqi", "ok" : 1 }

十三、测试脚本

切换到test

mongos>use test

mongos> for (var i = 1; i <= 100000; i++) db.lineqi.save({id:i,name:"12345678",sex:"male",age:27,value:"test"}); 

WriteResult({ "nInserted" : 1 })

十四、测试结果

查看分片信息

mongos> use config

switched to db config

mongos> db.chunks.find();

{ "_id" : "test.users-id_MinKey", "lastmod" : Timestamp(2, 0), "lastmodEpoch" : ObjectId("55ddb3a70f613da70e8ce303"), "ns" : "test.users", "min" : { "id" : { "$minKey" : 1 } }, "max" : { "id" : 1 }, "shard" : "set1" }
