基本环境:由于资源紧张,只有3台虚拟机的关系,只做两个replicaSet,每台机器配置分别如下:10.10.1.55这台机器安装 Primary1,configServer1, Arbiter110.10.1.56 安装 Primary2,configServer2, Arbiter210.10.1.57 安装 Secondary1,Secondary2,configServer3,mongos
1.55机器的配置文件如下:Primary1的conf文件:| 1234567891011 | dbpath=/data/mongodb/rs0_0logpath=/data/mongodb/log/rs0_0.loglogappend=trueport=40000bind_ip=192.168.11.55,10.10.1.55oplogSize=10000fork=truejournal = truereplSet=rs0directoryperdb=true |
Arbiter1的配置文件:| 1234567891011 | dbpath=/data/mongodb/rs0_arbiterlogpath=/data/mongodb/log/rs0_arbiter.loglogappend=trueport=40002bind_ip=192.168.11.55,10.10.1.55oplogSize=10000fork=truejournal = truereplSet=rs0directoryperdb=true |

分别通过mongod --config filename 来启动不同的mongo 进程,成功启动后可以通过netstat 查看在1.55 机器上分别分配了Primary1端口:40000,Arbiter1端口:40002,configureServer1端口:40006
1.56机器的配置:Primary2的配置文件:| 1234567891011 | dbpath=/data/mongodb/rs1_primarylogpath=/data/mongodb/log/rs1_p.loglogappend=truebind_ip=192.168.11.56,10.10.1.56directoryperdb=true port=40003oplogSize=10000fork=truejournal = truenoprealloc = truereplSet=rs1 |
Arbiter2配置文件:| 1234567891011 | dbpath=/data/mongodb/rs1_arbiterlogpath=/data/mongodb/log/rs1_a.loglogappend=truebind_ip=192.168.11.56,10.10.1.56directoryperdb=true port=40005oplogSize=10000fork=truejournal = truenoprealloc = truereplSet=rs1 |
ConfigureServer2配??文件:| 1234567891011 | dbpath=/data/mongodb/rs1_conflogpath=/data/mongodb/log/rs1_conf.loglogappend=truebind_ip=192.168.11.56,10.10.1.56directoryperdb=true port=40007oplogSize=10000fork=truejournal = truenoprealloc = trueconfigsvr=true |
分别通过mongod --config filename 来启动不同的mongo 进程,成功启动后可以通过netstat 查看在1.55 机器上分别分配了Primary2端口:40003,Arbiter2端口:40005,configureServer2端口:40007
1.56机器的配置:rs0_Secondary1配置:| 1234567891011 | dbpath=/data/mongodb/rs0_secondary1logpath=/data/mongodb/log/rs0_secondary1.loglogappend=trueport=40001bind_ip=192.168.11.57,10.10.1.57oplogSize=10000fork=truejournal = truereplSet=rs0directoryperdb=true |
rs1_Secondary1配置:| 1234567891011 | dbpath=/data/mongodb/rs1_secondary1logpath=/data/mongodb/log/rs1_secondary1.loglogappend=truebind_ip=192.168.11.57,10.10.1.57directoryperdb=true port=40004oplogSize=10000fork=truejournal = truenoprealloc = truereplSet=rs1 |

mongos 配置:(启动mongos路由器要注意多台服务器时间必须要同步,否则出现错误)| 1234 | logpath=/data/mongodb/log/mongos.logport = 40009configdb=10.10.1.55:40006,10.10.1.56:40007,10.10.1.57:40008fork = true |
分别通过mongod --config filename 来启动不同的mongo 进程,成功启动后可以通过netstat 查看在1.55 机器上分别分配了rs0_secondary1端口:40001,rs1_secondary1端口:40004,configureServer3端口:40008,mongos路由端口:40009现在用mongo shell登录primary1 配置replicaSet0,步骤如下:cfg={ "_id" : "rs0", "members" : [ { "_id" : 0, "host" : "10.10.1.55:40000" }, { "_id" : 1, "host" : "10.10.1.57:40001" } ] }rs.initiate(cfg)
rs.status()rs.addArb("10.10.1.55:40002")
现在用mongo shell登录primary2 配置replicaSet1,步骤如下:cfg={ "_id" : "rs1", "members" : [ { "_id" : 0, "host" : "10.10.1.56:40003" }, { "_id" : 1, "host" : "10.10.1.57:40004" } ] }rs.initiate(cfg)
rs.status()rs.addArb("10.10.1.56:40005")使用mongo shell登录mongos路由添加分片信息:
| 12345678910111213141516171819 | mongo --host 10.10.1.57 --port 40009mongos> sh.addShard("rs0/10.10.1.55:40000,10.10.1.57:40001"){ "shardAdded" : "rs0", "ok" : 1 }mongos> sh.addShard("rs1/10.10.1.56:40003,10.10.1.57:40004"){ "shardAdded" : "rs1", "ok" : 1 }mongos> sh.status()--- Sharding Status --- sharding version: { "_id" : 1, "version" : 4, "minCompatibleVersion" : 4, "currentVersion" : 5, "clusterId" : ObjectId("561c7bdd4315b18f9862adb4")} shards: { "_id" : "rs0", "host" : "rs0/10.10.1.55:40000,10.10.1.57:40001" } { "_id" : "rs1", "host" : "rs1/10.10.1.56:40003,10.10.1.57:40004" } databases: { "_id" : "admin", "partitioned" : false, "primary" : "config" } |
现在创建一个新的数据库来测试一下分片:mongos> use people
switched to db people
mongos> for(var i=1;i<10;i++) db.customers.insert({name:"jordan"+i,country:"American"})
WriteResult({ "nInserted" : 1 })
mongos> for(var i=1;i<10;i++) db.customers.insert({name:"gaga"+i,country:"American"})
WriteResult({ "nInserted" : 1 })
mongos> for(var i=1;i<10;i++) db.customers.insert({name:"ham"+i,country:"UK"})
WriteResult({ "nInserted" : 1 })
mongos> for(var i=1;i<10;i++) db.customers.insert({name:"brown"+i,country:"UK"})
WriteResult({ "nInserted" : 1 })
mongos> for(var i=1;i<10;i++) db.customers.insert({name:"ramda"+i,country:"Malaysia"})
WriteResult({ "nInserted" : 1 })
开始建立分片:| 1234567891011121314151617181920212223242526272829303132333435 | mongos> db.customers.ensureIndex({country:1,_id:1}){ "raw" : { "rs0/10.10.1.55:40000,10.10.1.57:40001" : { "createdCollectionAutomatically" : false, "numIndexesBefore" : 1, "numIndexesAfter" : 2, "ok" : 1 } }, "ok" : 1}mongos> sh.shardCollection("people.customers",{country:1,_id:1}){ "collectionsharded" : "people.customers", "ok" : 1 }mongos> sh.status()--- Sharding Status --- sharding version: { "_id" : 1, "version" : 4, "minCompatibleVersion" : 4, "currentVersion" : 5, "clusterId" : ObjectId("561c7bdd4315b18f9862adb4")} shards: { "_id" : "rs0", "host" : "rs0/10.10.1.55:40000,10.10.1.57:40001" } { "_id" : "rs1", "host" : "rs1/10.10.1.56:40003,10.10.1.57:40004" } databases: { "_id" : "admin", "partitioned" : false, "primary" : "config" } { "_id" : "test", "partitioned" : false, "primary" : "rs0" } { "_id" : "people", "partitioned" : true, "primary" : "rs0" } people.customers shard key: { "country" : 1, "_id" : 1 } chunks: rs0 1 { "country" : { "$minKey" : 1 }, "_id" : { "$minKey" : 1 } } -->> { "country" : { "$maxKey" : 1 }, "_id" : { "$maxKey" : 1 } } on : rs0 Timestamp(1, 0) |
现在由于数据量不多只有一个分片在rs0上,可以通过增加数据量来提高分片:
| 12 | for(var i=10;i<10000;i++) db.customers.insert({name:"ham"+i,country:"UK"})for(var i=10;i<10000;i++) db.customers.insert({name:"ramda"+i,country:"Malaysia"}) |
mongos> sh.status()
--- Sharding Status ---
sharding version: {
"_id" : 1,
"version" : 4,
"minCompatibleVersion" : 4,
"currentVersion" : 5,
"clusterId" : ObjectId("561c7bdd4315b18f9862adb4")
}
shards:
{ "_id" : "rs0", "host" : "rs0/10.10.1.55:40000,10.10.1.57:40001" }
{ "_id" : "rs1", "host" : "rs1/10.10.1.56:40003,10.10.1.57:40004" }
databases:
{ "_id" : "admin", "partitioned" : false, "primary" : "config" }
{ "_id" : "test", "partitioned" : false, "primary" : "rs0" }
{ "_id" : "people", "partitioned" : true, "primary" : "rs0" }
people.customers
shard key: { "country" : 1, "_id" : 1 }
chunks:
rs1 2
rs0 1
{ "country" : { "$minKey" : 1 }, "_id" : { "$minKey" : 1 } } -->> { "country" : "American", "_id" : ObjectId("561c7da73af7c7865defefb1") } on : rs1 Timestamp(2, 0)
{ "country" : "American", "_id" : ObjectId("561c7da73af7c7865defefb1") } -->> { "country" : "UK", "_id" : ObjectId("561c7db63af7c7865defefd4") } on : rs0 Timestamp(3, 1)
{ "country" : "UK", "_id" : ObjectId("561c7db63af7c7865defefd4") } -->> { "country" : { "$maxKey" : 1 }, "_id" : { "$maxKey" : 1 } } on : rs1 Timestamp(3, 0)
现在rs0上有一个分片,rs1上有两个分片
