Next, build a Cluster, which consists of four servers, including two Shard, three Config, and one Route Each Shard is composed of a Replica Set, and each Replica Set is composed of two Mongod nodes and one vote node. The configuration process is as follows: 1. The four servers start the corresponding Mongod process respectively: 192.168.95.216/Usr/local/

Designed to provide scalable, high-performance data storage solutions for Web applications. It is widely used for its advantages such as high performance, easy to deploy, easy to use and easy to store data. Its installation configuration is fairly simple, like the lightweight MySQL, but features tittle. This article mainly describes the start and
