Basic environment:

Due to the shortage of resources, there are only three virtual machines, and only two replicaSet are made. The configuration of each machine is as follows:

10.10.1.55 this machine installs Primary1,configServer1 and Arbiter1

10.10.1.56 install Primary2,configServer2, Arbiter2

10.10.1.57 install Secondary1,Secondary2,configServer3,mongos

1.55 the configuration file of the machine is as follows:

Conf file for Primary1:

Dbpath=/data/mongodb/rs0_0logpath=/data/mongodb/log/rs0_0.loglogappend=trueport=40000bind_ip=192.168.11.55,10.10.1.55oplogSize=10000fork=truejournal = true#noprealloc = truereplSet=rs0directoryperdb=true

Configuration file for Arbiter1:

Dbpath=/data/mongodb/rs0_arbiterlogpath=/data/mongodb/log/rs0_arbiter.loglogappend=trueport=40002bind_ip=192.168.11.55,10.10.1.55oplogSize=10000fork=truejournal = true#noprealloc = truereplSet=rs0directoryperdb=true

Configuration file for ConfigServer1:

Dbpath=/data/mongodb/rs0_conflogpath=/data/mongodb/log/rs0_conf.loglogappend=trueport=40006bind_ip=192.168.11.55,10.10.1.55fork=truejournal = true#noprealloc = trueconfigsvr=truedirectoryperdb=true

Different mongo processes are started through mongod-- config filename. After successful startup, you can view through netstat that the Primary1 port is assigned on the 1.55 machine: 40000 discipline Arbiter1 port: 40002 training reServer1 port: 40006

1.56 configuration of the machine:

Configuration file for Primary2:

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 profile:

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 profile:

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

Different mongo processes are started through mongod-- config filename. After starting successfully, you can view the Primary2 port assigned on the 1.55 machine via netstat: 40003Magi Arbiter2 Port: 40005MakeReServer2 Port: 40007

1.56 configuration of the machine:

Rs0_Secondary1 configuration:

Dbpath=/data/mongodb/rs0_secondary1logpath=/data/mongodb/log/rs0_secondary1.loglogappend=trueport=40001bind_ip=192.168.11.57,10.10.1.57oplogSize=10000fork=truejournal = true#noprealloc = truereplSet=rs0directoryperdb=true

Rs1_Secondary1 configuration:

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

ConfigureServer3 configuration:

Dbpath=/data/mongodb/confSvr3logpath=/data/mongodb/log/conf3.loglogappend=truebind_ip=192.168.11.57,10.10.1.57directoryperdb=true port=40008oplogSize=10000fork=truejournal = trueconfigsvr=true

Mongos configuration: (when starting a mongos router, note that multiple server times must be synchronized, otherwise an error will occur)

Logpath=/data/mongodb/log/mongos.logport = 40009configdbstation 10.10.1.55 freed 40006 Magazine 10.10.1.56 Freud 40007 minicolor 10.10.1.57 Glop 40008 fork = true

Different mongo processes are started through mongod-- config filename. After starting successfully, you can view through netstat that the rs0_secondary1 port is assigned on the 1.55 machine: 40001memrs1secondary1 port: 40004dyadireServer3 port: 40008dymongos routing port: 40009

Now log in to primary1 with mongo shell to configure replicaSet0, as follows:

Cfg= {"_ id": "rs0", "members": [{"_ id": 0, "host": "10.10.1.55 id 40000"}, {"_ id": 1, "host": "10.10.1.57virtual 40001"}]}

Rs.initiate (cfg)

Rs.status ()

Rs.addArb ("10.10.1.55 40002")

Now log in to primary2 with mongo shell to configure replicaSet1, as follows:

Cfg= {"_ id": "rs1", "members": [{"_ id": 0, "host": "10.10.1.56 id 40003"}, {"_ id": 1, "host": "10.10.1.57 Suzhou 40004"}]}

Rs.initiate (cfg)

Rs.status ()

Rs.addArb ("10.10.1.56 40005")

Use mongo shell to log in to mongos route to add sharding information:

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"}

Now create a new database to test the shards:

Mongos > use people

Switched to db people

Mongos > for (var iTunes 1 / 2 / 1 / 2 / 1 / 2 / 1 / 2 / 1 / 2 / 1 / 2 / 1 / 2 / 1 / 2 / 1 / 2 / 3 / 3 / 3 / 1 / 2 / 3 / 3 / 3 / 3 / 1 / 2 / 3 / 1 / mongos / for / var / for / for / var / item1 I 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)

Now, since there is only one shard on the rs0, you can increase the amount of data to improve the shard:

For (var iTunes 10 rs1 Timestamp I > {"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)

Now there is one shard on rs0 and two shards on rs1.
