After reading the mongodb authoritative guide, it is more appropriate to use the replica set for read/write splitting, and the general system is enough to use it. It is easy to find. If you do not describe it, you can only describe the key steps. The two servers are 201 and 202 nodes, the two are initially configured on 202, and the other is added on 201. Deploy two nodes first202:./Mongod -- dbpath./db1 -- port 10002 -- replSet blort/Server202: 10001

By default: The primary node is responsible for data read and write, the secondary node backs up the data on the primary node, but the arbiter nodeData is not synchronized from the primary nodeArbiter Effect:When the primary node fails, it can select a primary node from the second node and will not participate in the data read and write.MongoDB uses oplog.rs to synchronize data sets between replication sets.This article is from the DBA Sky blog, so be sure to keep this source http://9425473.blog
