Since replica set is already part of MongoDB's advanced application, the basic knowledge of MongoDB below is not covered by the author, please refer to MongoDB Manual. Here are a variety of scenarios that tell you how to create a

MongoDB is an open-source non-sql database engine. MongoDB is extensible and is a substitute for standard relational database management systems (RDBMS). A replica set can also provide access to your data when a node fails. Install MongoDB 1. Ensure that each member of the replica set is set hostnameNano/etc/hostname/etc/hostname:Europa 2. Create a file to hold the configuration information for the Mongo

MongoDB Replica set First, Introduction: In simple terms, the replica set (Replica set) is the master-slave cluster with automatic fault recovery. The most obvious difference between a master-slave cluster and a replica set is that the replica set does not have a fixed "ma

This document records the process of building a shard cluster from a MongoDB replica set from scratch.We're going to create a distributed cluster like this: There are two Shard, each shard a replica set, each with two copies (a aribiter in the actual product application), three config servers, and a mongos. The steps are as follows:1. Replica setReplica set AMkdi

Overview replica set is a master-slave replication, and is a master-slave replication with self-failover capability. Overcome the shortcomings of the above-mentioned master-slave replication. After you implement a host server problem. No human intervention is required. The system itself proactively elects a new primary server function.deployment DiagramThe map is copy others, interested to be able to view the person's blog, written very good

About Replica Sets A replica set is a process that synchronizes data across multiple machines.Replica collectives provide data redundancy and extend data availability. Saving data on multiple servers avoids data loss due to a single server.It can also be freed from hardware failures or service outages, with additional copies of data that can be dedicated to disaster recovery or backup from a single machine

We know that Microsoft introduced the Hyper-V replica technology in the release of hyper-v3.0, which is a free disaster recovery tool in Hyper-V to create and maintain replicas of virtual machines (VMS) that, in the event of catastrophic loss, can be transferred to a replica virtual machine, enabling a rapid recovery of the production environment, to some extent ensuring Service continuity.A detailed introd

Tags: MongoDB replica set deploymentDeploying Replication SetsA replica set consisting of three nodes provides sufficient redundancy for network failure or other system failures. The replica set also has the ability to have sufficient distributed read operations. The replica set should maintain an odd number of nodes,

MongoDB cluster building (master-slave replication, replica and) (5), mongodb master-slaveVi. Architecture ManagementMongodb master-slave clusters are divided into two types:1: master-Slave replication (master-Slave) -- The Slave server will not automatically change to the master server. You need to set the Slave server.2: replica Sets (replica set) -- if the mas

I have already written the first article about how to build a Mongo database replica set on the windows platform: How to build a Mongo database replica set on the windows platform. Article 2: in this article, we will summarize the replica set and analyze its working principles. I. Common application scenarios and Data I have already written the first article abou

Introduction to the high availability of a replica set The replica set achieves high availability through automatic failover. When the master node fails, the slave node can be elected as the master node, and this process is automatically performed in most cases, manual intervention is not required. In some cases, data rollback is required for automatic failover. Deployment of
