In my previous article i have explained installation of mongodb in Centos.Follow the guidelines in http://www.goserverspace.com/2017/09/mongodb-is-nosql-database-which.html
In this article Iam explaining about enabling user authentication in mongodb.we will enable
authentication for users to prevent that another user without sufficient
privileges is able to see the data on the database.
On our CentOS 7 server, MongoDB
is running under systemd with an init script in the '/etc/init.d/' dirctory. We
will edit that script to force the mongodb service to run with the '--auth'
option.
Go to the '/etc/init.d/'
directory and edit the "mongod" file:
#cd /etc/init.d/
#vim mongod
On line 15 you will find the
"OPTION" variable, there we will add the "mongod" option.
OPTIONS="
--auth -f $CONFIGFILE"
Save the file.
Reload the systemd service and
restart MongoDB.
#systemctl daemon-reload
#systemctl restart mongod
Next, we have to test the
configuration by logging into the mongo shell and switch to the admin database,
then try to see the admin users
#mongo
use admin
show users
You will see an error about
the unauthorized execution of the command in the database admin.
Now we need to use the command 'db.auth()' for the authentication.
db.auth('admin', 'admin123')
Now you can see the users with
their roles and the privileges.
