MongoDB Configuration Master-slave replication

MongoDB Configuration Master-slave replication is much simpler than MySQL

1, install, start with the configuration file

2. Modify the configuration file

Configuration of the Master

[Email protected] mongodb]# cat/etc/mongod.conf

port=27017

Dbpath=/usr/local/mongodb/data

Logpath=/usr/local/mongodb/logs

Logappend=true

Journal=true

Fork=true

Master=true

From the configuration

[Email protected] home]# cat/etc/mongod.conf

port=27017

Dbpath=/usr/local/mongod/data

Logpath=/usr/local/mongod/logs

Logappend=true

Journal=true

Fork=true

Slave=true

source=192.168.56.105:27017

Two configurations to do so.

Then load the configuration again and there's no problem.

View Master-Slave status

Db.printreplicationinfo (): View the status of the primary node

Db.printslavereplicationinfo (): View the status from a node
