Install MongoDb on Redhat 7/CentOS 7

1. Add repository

/etc/yum.repos.d/mongodb-org-3.2.repo

name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.2/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-3.2.asc

2. Install mongodb.

sudo yum install -y mongodb-org

semanage port -a -t mongod_port_t -p tcp 27017

sudo service mongod start

You can check the mongoDB logs using the following command.

tail -f /var/log/mongodb/mongod.log

sudo vi /etc/mongod.conf
