MongoDB cluster in Linux-replica set Environment Construction MongoDB replica sets are suitable for scenarios with fewer writes and more reads. You can use message queues for write control to reduce the pressure on highly concurrent writes. The Application Scenario of replica set should be selected based on the project requirements. If there is a high concurrency

I will talk about the replica set in the previous phase. The primary features of the replica set are embodied in two aspects: 1. the replica set does not have a specific primary database. 2. If there is a fault such as a crash, the cluster selects a database as the primary database, which provides the automatic fault recovery function. Next we will perform the fo

Tags: auth date introduction states like theory knowledge role bash downloadBrief introduction MongoDB Replication (replication) is the process of synchronizing data across multiple servers. The master node records all operations on it, oplog the primary node periodically from the node, and then performs these operations on its own copy of the data, ensuring that the data from the node is consistent with the primary node. Replication provides redundant backups of data and stores copies of data o

MongoDB Sharding Cluster is a horizontally scalable mode. It is very powerful when the data volume is large. I have been trying to study three roles to build a MongoDB Sharding Cluster: 1. Shard Server: mongod instance, used to store actual data blocks. In the actual production environment, a role of Shard Server can be assumed by one Replica Set of several machines to prevent single point of failure (spof) on the host. 2. Config Server: mongod instan

MongoDB supports failover and implementation redundancy across multiple machines through asynchronous replication. Only one machine is used for write operations at the same time in multiple machines, and because of this, MongoDB provides the assurance of data consistency. The machine that plays the role of primary can distribute the read operation to Slave.MongoDB high availability is divided into two types:Master-slave master-slave replicationYou only need to add the –master parameter when a se
