=== Enable authentication ===
* Connect to mongo instance:
mongo
* Add an admin user:
<nowiki>
use admin
db.createUser(
{
user: "myUserAdmin",
pwd: "abc123",
roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
}
)</nowiki>
* Edit configuration file
sudo nano /etc/mongod.conf
* Restart mongoDB server:
sudo service mongod restart
* connect to your instance:
<nowiki>security:
authorization: enabled</nowiki>
==== Add user roles ====
<nowiki>use reporting
db.grantRolesToUser(
"reportsUser",
[
{ role: "read", db: "accounts" }
]
)</nowiki>
==== Revoke user roles ====
<nowiki>use reporting
db.revokeRolesFromUser(
"reportsUser",
[
{ role: "readWrite", db: "accounts" }
]
)</nowiki>
==== Create User ====
<nowiki>use test
db.createUser(
{
user: "tester",
pwd: "password",
roles: [
{ role: "read", db: "test1" },
{ role: "read", db: "test2" },

=== Disable Transparent Huge Pages (THP) ===
Create the init.d script.<br />
Create the following file at /etc/init.d/disable-transparent-hugepages:
<source lang="bash">#!/bin/sh
### BEGIN INIT INFO
# Provides: disable-transparent-hugepages

esac</source>
Make it executable:
