Mongodb version 3.2.7

Resource division:

192.168.1.11Rose 27017-"config server"

192.168.1.11 27018 Murray-"mongos"

192.168.1.11 27019 "mongod Service"

192.168.1.11 27020 "mongod Service"

Since they are all built on the same machine, a single mode is adopted here. Of course, you can make mongod services into replica sets, and config server can also be used as replica sets, so I won't repeat them here.

Direct posting configuration:

192.168.1.11:27017

Path: / var/log/mongodb/mongod.log

DbPath: / mongodb/data

PidFilePath: / var/run/mongodb/mongod1.pid

Port: 27017

BindIp: 192.168.1.11

Sharding:

ClusterRole: configsvr

Then start config server

Mongod-f / etc/mongod.conf

192.168.1.11 27018 UV-> mongos

# storage:

# dbPath: / mongodb2/data

# journal:

# enabled: true

Comment out the above options, and the following error will occur if you do not comment:

Path: / var/log/mongodb/mongod2.log

PidFilePath: / var/run/mongodb/mongod2.pid

Port: 27018

BindIp: 192.168.1.11

Sharding:

ConfigDB: 192.168.1.11:27017

Then start the service:

Mongos-config mongod.conf

192.168.1.11:27019

Path: / var/log/mongodb/mongod3.log

DbPath: / mongodb3/data

PidFilePath: / var/run/mongodb/mongod3.pid

Port: 27019

BindIp: 192.168.1.11

Sharding:

ClusterRole: shardsvr

Then start the service:

Mongod-f

192.168.1.11:27020

Path: / var/log/mongodb/mongod4.log

DbPath: / mongodb4/data

PidFilePath: / var/run/mongodb/mongod4.pid

Port: 27020

BindIp: 192.168.1.11

Sharding:

ClusterRole: shardsvr

Then start the service:

Mongod-f

Check to see if the port is listening

Then log in to mongos

Mongo-host 192.168.1.11-port 27018

Then add sharding

Then check the sharding status again as shown below:

You can clearly see that two partitions sharding have been added.

Mongos > sh.enableSharding (testdb)-> enable sharding partitions for testdb

Mongos > sh.shardCollection (fullName,key,unique)-> Partition collection

Sh.shardCollection ("huangdb.testcoll", {Age:1,Name:1}): partition sequentially by age and first name
