How To Install MongoDB On CentOS 7

From Wikipedia,

MongoDB (from “humongous”) is a cross-platform document-oriented database. Classified as a NoSQL database, MongoDB eschews the traditional table-based relational database structure in favor of JSON-like documents with dynamic schemas (MongoDB calls the format BSON), making the integration of data in certain types of applications easier and faster. Released under a combination of the GNU Affero General Public License and the Apache License, MongoDB is free and open-source software.

First developed by the software company 10gen (now MongoDB Inc.) in October 2007 as a component of a planned platform as a service product, the company shifted to an open source development model in 2009, with 10gen offering commercial support and other services.Since then, MongoDB has been adopted as backend software by a number of major websites and services, including Craigslist, eBay, Foursquare, SourceForge, Viacom, and the New York Times, among others. MongoDB is the most popular NoSQL database system.

3 – Enable and Start Mongodb Server

[root@unixmen-centos7 ~]# chkconfig  mongod  on
[root@unixmen-centos7 ~]# service   mongod start
Starting mongod (via systemctl):                           [  OK  ]

 4 – check if its running

[root@unixmen-centos7 ~]# ps -ef  |  grep   mongo
mongod    2587     1  1 05:24 ?        00:00:08 /usr/bin/mongod -f /etc/mongod.conf
root      2984  2270  0 05:34 pts/1    00:00:00 grep --color=auto mongo
[root@unixmen-centos7 ~]# netstat  -an  |  grep   27017
tcp        0      0*               LISTEN
unix  2      [ ACC ]     STREAM     LISTENING     20600    /tmp/mongodb-27017.sock
[root@unixmen-centos7 ~]#

5 – Open the port on firewall

[root@unixmen-centos7 ~]# firewall-cmd --zone=public --add-port=27017/tcp --permanent
[root@unixmen-centos7 ~]# firewall-cmd --reload

6 – check from other machine

[root@unixmen-centos7 ~]# telnet  27017
