CENTOS7 installation MongoDB3.4

Brief introduction
MongoDB is a product between a relational database and a non-relational database, and is the most versatile and most like relational database in a non-relational database. The data structure he supports is very loose and is a JSON-like Bson format, so you can store more complex data types. MONGO's biggest feature is that the query language he supports is very powerful, and its syntax is a bit like an object-oriented query language that almost implements most of the functionality of a relational database single-table query, and also supports indexing of data.

Packages Package Description
The MongoDB official source contains the following dependent packages:
MONGODB-ORG:MONGODB metadata package, install the following four packages automatically:
1.mongodb-org-server: Contains the MongoDB daemon and related configuration and initialization scripts.
2.mongodb-org-mongos: Contains the daemon for MONGOs.
3.mongodb-org-shell: Contains the MONGO shell.
4.mongodb-org-tools: Tools with MongoDB: Mongoimport, Bsondump, Mongodump, Mongoexport, Mongofiles, Mongooplog, Mongoperf, Mongorestore, Mongostat, and Mongotop.

Installation steps
