Installing MongoDB database on CentOS 7 4.0.0 latest Version

About MongoDB

MongoDB (from the English word "humongous", the Chinese meaning "huge") is an open-source database that can be applied to businesses of all sizes, industries and applications. As a database for agile development, MongoDB's data schema can be updated flexibly as the application progresses. At the same time, it also provides developers with the functionality of traditional databases: two-level indexes, a complete query system, and strict consistency, among other things.

MongoDB enables businesses to be more agile and scalable, and businesses of all sizes can use MongoDB to create new applications, increase productivity with their customers, accelerate time-to-market, and reduce enterprise costs.

MongoDB is a database designed for scalability, high performance, and high availability. It can scale from a single-server deployment to a large, complex, multi-datacenter architecture. With the advantage of memory computing, MONGODB can provide high-performance data read and write operations. MongoDB's local replication and automatic failover capabilities give your application enterprise-class reliability and operational flexibility.
