MongoDB分片布屬（Linux）

1、創建數據文件夾

[root@Mongo-server-A /]# mkdir data

[root@Mongo-server-A /]# cd /data
[root@Mongo-server-A data]# mkdir config
[root@Mongo-server-A data]# mkdir shard1
[root@Mongo-server-A data]# mkdir shard2
[root@Mongo-server-A data]# mkdir log
[root@Mongo-server-A data]# ls

2、進入mongodb目錄

3、創建啓動配置文件

[root@Mongo-server-A bin]# vi shard1.conf 

dbpath = /data/shard1
shardsvr = true
replSet = shard1
bind_ip = 192.168.2.88
#auth = true
port = 10001
oplogSize = 100
logpath = /data/log/shard1.log
logappend = true
profile = 1
slowms = 5
rest = true
fork = true

[root@Mongo-server-A bin]# vi shard2.conf 

dbpath = /data/shard2
shardsvr = true
replSet = shard2
bind_ip = 192.168.2.88
#auth = true
port = 10002
oplogSize = 100 
logpath = /data/log/shard2.log
logappend = true
profile = 1
slowms = 5
rest = true
fork = true

[root@Mongo-server-A bin]# vi shard3.conf 

dbpath = /data/shard3
shardsvr = true
replSet = shard3
bind_ip = 192.168.2.88
#auth = true
port = 10002
oplogSize = 100 
logpath = /data/log/shard3.log
logappend = true
profile = 1
slowms = 5
rest = true
fork = true

4、啓動

[root@Mongo-server-A bin]# ./mongod -f shard1.conf 

[root@Mongo-server-A bin]# ./mongod -f shard2.conf 

[root@Mongo-server-A bin]# ./mongod -f shard3.conf 

5、對分片（shard1\shard2）配置進行初使化

config = {_id: "shard1", members: [

                          {_id: 0, host: "192.168.2.88:10001"},

                          {_id: 1, host: "192.168.2.89:10001"},

                          {_id: 2, host: "192.168.2.90:10001"}]

           }

config = {_id: "shard2", members: [

                          {_id: 0, host: "192.168.2.88:10002"},

                          {_id: 1, host: "192.168.2.89:10002"},

                          {_id: 2, host: "192.168.2.90:10002"}]

config = {_id: "shard3", members: [

                          {_id: 0, host: "192.168.2.88:10003"},

                          {_id: 1, host: "192.168.2.89:10003"},

                          {_id: 2, host: "192.168.2.90:10003"}]

6、創建配置服務器啓動文件

configsvr.conf

dbpath = /data/config

configsvr = true

port = 20000

logpath = /data/log/config.log

logappend = true

fork = true

7、啓動配置服務

[root@Mongo-server-A bin]# ./mongod -f configsvr.conf

8、創建配置路由配置文件

mongos.conf

configdb = 192.168.2.88:20000

port = 30000 

chunkSize = 5

logpath = /data/log/mongos.log

logappend = true

fork = true

9、啓動路由並登錄

[root@Mongo-server-A bin]# ./mongos -f mongos.conf

[root@Mongo-server-A bin]# ./mongo 192.168.2.88:30000

10、加入分片

mongos> use admin
switched to db admin
mongos> db.runCommand( {addshard:"shard1/192.168.2.88:10001,192.168.2.89:10001,192.168.2.90:10001", name:"shard1", maxsize:20480} )

{ "shardAdded" : "shard1", "ok" : 1 }
mongos> db.runCommand( {addshard:"shard2/192.168.2.88:10002,192.168.2.89:10002,192.168.2.90:10002", name:"shard2", maxsize:20480} )

{ "shardAdded" : "shard2", "ok" : 1 }

mongos> db.runCommand( {addshard:"shard3/192.168.2.88:10003,192.168.2.89:10003,192.168.2.90:10003", name:"shard3", maxsize:20480} )

{ "shardAdded" : "shard3", "ok" : 1 }

11、查看分片

mongos> db.runCommand( { listshards : 1 } )
{
        "shards" : [
                {
                        "_id" : "shard1",
                        "host" : "shard1/192.168.2.88:10001"
                },
                {
                        "_id" : "shard2",
                        "host" : "shard2/192.168.2.88:10002"
                }
        ],
        "ok" : 1
}

12、測試

mongos> use test
switched to db test
mongos> show dbs
admin   0.078125GB
config  0.1875GB
mongos> db.userinfo.insert({userid:10234,name:'fengyi'})
mongos> db.userinfo.find()
{ "_id" : ObjectId("4f60ee47fd58cd2bece6291b"), "userid" : 10234, "name" : "fengyi" }
mongos> 

netstat -lntp|grep mongod
