1. IntroductionMaster-slave replication is the most common way to replicate MongoDB. This method is very flexible and can be used for backup, failure recovery, read scaling, and so on.The most basic way to set up is to establish a master node and one or more slave nodes, eac
Mongodb provides a Replication mechanism that helps us easily implement read/write splitting solutions and supports data security in unexpected situations such as disaster recovery (server power failure.
In earlier versions (1.6), Mongo provides two replication modes: master-slave
In practice, we will explain how to build MongoDB and master-slave replication. Because there is only one server, you can only modify the port number to implement the master-slave MongoDB
It took two days to learn MongoDB, and today came into contact with MONGO's master-slave configuration, to write it down1. Open two MONGO server (for a master one from, no security validation related parameters: can be viewed with mongd-help)Mongod--bind_ip IP--port port--dbpath d:\. --replset Name.... (from a similar

1. Set the master node (IP: 10.0.0.1)
2. Set slave node (IP: 10.0.0.2)
3. Add the master node information (IP: 10.0.0.3) to the sources set)
4. Modify the slave node configuration to 10.0.0.4: 27037 as the source. You can use insert and remove to complete the process.
