[root@db02 ~]# yum clean all

Latest stable release

[root@db02 ~]# yum install -y mongodb-org

For a specific release: version 3.0.3

[root@db02 ~]# yum install -y mongodb-org-3.0.3 mongodb-org-server-3.0.3 mongodb-org-shell-3.0.3 mongodb-org-mongos-3.0.3 mongodb-org-tools-3.0.3

Version 3.2.9

[root@db02 ~]# yum install -y mongodb-org-3.2.9 mongodb-org-server-3.2.9 mongodb-org-shell-3.2.9 mongodb-org-mongos-3.2.9 mongodb-org-tools-3.2.9

Version 3.2.10

[root@db02 ~]# yum install -y mongodb-org-3.2.10 mongodb-org-server-3.2.10 mongodb-org-shell-3.2.10 mongodb-org-mongos-3.2.10 mongodb-org-tools-3.2.10

If you have older version of openssl than version: 1.0.1e, you can get issues after installajon/upgrading MongoDB 3.x  

Config File:

[root@db02 ~]# cat /etc/mongod.conf

# This is a mongo.conf file

dbpath=/db/mongo

logpath=/var/log/mongo/mongod.log

logappend=true

quiet = true

fork = true

port = 27017

replSet = rs0

oplogSize = 1000

Start/Stop MongoDB

[root@db02 ~]# /etc/init.d/mongod start

[root@db02 ~]# /etc/init.d/mongod stop

Other options

Usage: /etc/init.d/mongod {start|stop|status|restart|reload|force-reload|condrestart}

If you get some complaints about process limits (observered in version 3.2.9) when starting, create a file and add the nproc value manually in following file. 

[root@db02 ~]# cat /etc/security/limits.d/99-mongodb-nproc.conf

mongod     soft      nproc        64000

AUTO START:

It is observed that version 3.2.x has issue better to check and fix autostart 

[root@db02 ~]# chkconfig --list |grep mongod

mongod          0:off   1:off   2:off    3:off    4:off    5:off    6:off

[root@db02 ~]# chkconfig mongod on 

[root@ios-nod-qa-db02 ~]# chkconfig --list| grep mongod

mongod          0:off   1:off   2:on    3:on    4:on    5:on    6:off
